So I thought I would improve my previous design to use a Nokia 5110 LCD in the design instead of the 1602 LCD. This Nokia display gives five or six lines of display so you can see more information.</p><p>I use a computer power AC adapter to power the colloidal silver maker at about 19 VDC. Most people say that 18 to 20 volts is ideal for this application. </p><p>This is a picture of the Nokia display. I added the ability to see the current setting as it reduces every time the current exceeds 1ma.

I added a can of seafoam to less that 1/4 tank of gas - thats twice the recomended mixture. When I was done with both things there was black suit on the pavement near the exhaust pipe.

My first attempts was to wrap the LED strips around the dead light bulbs. That did not work that well. My next attempt is to make a signboard and cover it with eight LED strips on each side.This will require 12 volts at 20 amps to run it! I switched the power to wire nuts and 12 volt 10 amp power supplies after this picture was taken. The barrel connectors in the picture got really hot.</p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh6cTECQ0RRWAn2i71abo7jM-vc-HiDYKhXHsjjLl5CkMsu5OmQNqqv2Y4L8vNL2rKqxvKnp0kamGimNASlZ-efImAUvMj4QsZ7dgyuh9SnbA0przmhdOkQWaN4rMMn5a0vofsNt_88EhKa7YHutL3jmoieAEmiBSKXymKXxTwu9zbI8dIt8hA1b7HOB6k/s2989/Light%20panel.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="2989" data-original-width="1868" height="320" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh6cTECQ0RRWAn2i71abo7jM-vc-HiDYKhXHsjjLl5CkMsu5OmQNqqv2Y4L8vNL2rKqxvKnp0kamGimNASlZ-efImAUvMj4QsZ7dgyuh9SnbA0przmhdOkQWaN4rMMn5a0vofsNt_88EhKa7YHutL3jmoieAEmiBSKXymKXxTwu9zbI8dIt8hA1b7HOB6k/s320/Light%20panel.jpg" width="200" /></a></div><br />This is the sign with the old LED strips wrapped around the bulbs.<div><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhjoybME8e2pmzuKp7PRj8pdomiiS_-sm5MjcSdrW8YPGLWtkRf5b2_jvv-iE1pyTw0PNAs2NzQe09-cT9J-ZMcZv9F521yRWRWQ9mNSEeJg2KnNRkkZqzhHJQj95O1E3RvOUiwEMwaQJ-j64GPIWB5RvrsVLv65Ab2NATLXerAzJq8LhiUq1iVMlOSHHg/s720/new%20sign-old.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="514" data-original-width="720" height="228" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhjoybME8e2pmzuKp7PRj8pdomiiS_-sm5MjcSdrW8YPGLWtkRf5b2_jvv-iE1pyTw0PNAs2NzQe09-cT9J-ZMcZv9F521yRWRWQ9mNSEeJg2KnNRkkZqzhHJQj95O1E3RvOUiwEMwaQJ-j64GPIWB5RvrsVLv65Ab2NATLXerAzJq8LhiUq1iVMlOSHHg/s320/new%20sign-old.jpg" width="320" /></a></div><br />This is the LED's that I am using in the new sign lighting panel.<br /><br /></div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgplwcZHTk0ozsUboh-jOuOfWgXJuRFduWA4tbqW_WD6SE2qNHFQYDDi1kIhlwniY7A5pjGv1HHpHVaFaBLxtdq8N1hoivjnsvI80z_Z-Gej75NYf7zWDPpNcTZbO3YTp7CQ9EL-YQuHM0cxh6awowLDmOM9KMWibhRqWNEFNOaWSc5PZV9_t4S1_S5-bE/s704/leds.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="236" data-original-width="704" height="134" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgplwcZHTk0ozsUboh-jOuOfWgXJuRFduWA4tbqW_WD6SE2qNHFQYDDi1kIhlwniY7A5pjGv1HHpHVaFaBLxtdq8N1hoivjnsvI80z_Z-Gej75NYf7zWDPpNcTZbO3YTp7CQ9EL-YQuHM0cxh6awowLDmOM9KMWibhRqWNEFNOaWSc5PZV9_t4S1_S5-bE/w400-h134/leds.jpg" width="400" /></a></div><br /><div>WARNING!

The distance was about 3/4 of a mile. The results were excellent! I had no knowledge of how to do this other than using repeaters to pick up internet from a house or two away. This time I needed to reach a building that was a few blocks away. </p><p>I used google maps to see if there was a straight shot between the locations. Then I went up on the roofs but could not see all the way to the other end from either direction. There was nothing visible in the way. It was a narrow shot as some pine trees surrounded my house but there was a gap in just the right direction. </p><p>I bought a model that has lots of LED's on the side to be able to troubleshoot any issues. I installed the "A" unit on the roof of my house. Then the "B" unit (You can change A to B with a switch) was installed on the building. I was amazed at the results the signal level was 100%! But there was no internet at the receiving end. The issue turned out to be that I had two internet cables at my house with a union in the middle and lost a connection somewhere. Switching to 100 foot exterior grade cables at both ends resolved that issue.</p><p>Here is the ad for the bridge on eBay:<br /></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgrmZsGrQRHDEHk0cOjIAnAZ-opSzPVknVtKQRX5WS28k3KXbMARCRwFsx0JkIUgleOL7C4KPb9KwoZp8vyxpptYDaCkhjRE1_p3VmJwxKxea9WOzyMzUQvntqxMfvNQ2BhyVVmC2Wv-oJjDVrmh2OMtNqnCXnJ22ROlX7lxDdSfAK6EiUGh4y9v0sVR7E/s608/Bridge.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="337" data-original-width="608" height="221" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgrmZsGrQRHDEHk0cOjIAnAZ-opSzPVknVtKQRX5WS28k3KXbMARCRwFsx0JkIUgleOL7C4KPb9KwoZp8vyxpptYDaCkhjRE1_p3VmJwxKxea9WOzyMzUQvntqxMfvNQ2BhyVVmC2Wv-oJjDVrmh2OMtNqnCXnJ22ROlX7lxDdSfAK6EiUGh4y9v0sVR7E/w400-h221/Bridge.jpg" width="400" /></a></div><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjzuMxJF6j5Z2dwuqWcVKi1TQXcPuhqGXHu7L72m1onvLY3_lSl8kQN5czdPPu-R2IdPOw1qOxB7e3AOxv7HRt75yYJSRQ-xomzyNG7wtkXAJ6leqwXWcS_RExfm-Awb-8nQapfAmIjDPFDfh1Shbw9AcJb-16ufZTazipLnpjCsHPNCqCJYYbnf_CNsQA/s1208/Bridge2.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="603" data-original-width="1208" height="200" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjzuMxJF6j5Z2dwuqWcVKi1TQXcPuhqGXHu7L72m1onvLY3_lSl8kQN5czdPPu-R2IdPOw1qOxB7e3AOxv7HRt75yYJSRQ-xomzyNG7wtkXAJ6leqwXWcS_RExfm-Awb-8nQapfAmIjDPFDfh1Shbw9AcJb-16ufZTazipLnpjCsHPNCqCJYYbnf_CNsQA/w400-h200/Bridge2.jpg" width="400" /></a></div><p>This is the receiving unit.

I picked up theis fried amplifier at a Hmfest from a friend for like $10 for the poweer transformer. I tested the output transistors and all but one were shorted. So I decided to rebuild it with a dual TDA7394 amplifier board for $22 on eBay. The power transformer is 60 VCT so the rectified power is + and - 42 volts DC. That is a little high for the IC but within its specs. It should deliver 100 watts per channel into 8 ohms without any problems.</p><p>Here is the old circuit board.

Back in 2020 I had built a AMG8833 based camera. Its resolution was only 8x8 pixels. The MLX90640 is 32x24 pixels, that is a huge improvement for about $40. I was hoping that I could just unplug the one sensor and plug in the new one. Things are never that simple! </p><p>This is a picture of the completed project. The camera does not do a good job. I tried multiple cameras and they all fail to show the varying shades of colors!

Then I realized that the module I have has an extra IC on it. I had ordered a MLX90640 module on eBay for a little over $40.

The filter capacitor did not help, so I am running the LED strips off the ESP32 pins via a 220 ohm resistor. So far no problems! The issue was that IO12 must be tied low during boot so do not use it for LED strips!</div><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjgU4xHX40Of1QMpVZsluPWT8Q-jG80TxzDLbwMYW-VgDnTSGylCajHF-O3wKsdFiv3aRW2_PNs5pQSsiQpG1bvyNsyUrIKRA8ToGg3aetuejWiYcKL0XqCR2qip73mRA9omjDdW5BFcR8m4TpsEZnMSOpyPnkng5h53Kf6-bldJs_r8egeoiqL1N9rocQ/s2211/20231011_202319.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1861" data-original-width="2211" height="269" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjgU4xHX40Of1QMpVZsluPWT8Q-jG80TxzDLbwMYW-VgDnTSGylCajHF-O3wKsdFiv3aRW2_PNs5pQSsiQpG1bvyNsyUrIKRA8ToGg3aetuejWiYcKL0XqCR2qip73mRA9omjDdW5BFcR8m4TpsEZnMSOpyPnkng5h53Kf6-bldJs_r8egeoiqL1N9rocQ/s320/20231011_202319.jpg" width="320" /></a></div><div><br /></div>This is a sample of scrolling text using WLED.

My regular place to get the car inspected was having issues with its inspection machine. He said to try back next week. It was still bad the next week, so I called another garage. They were booked for 2 weeks but they could get me in then. Then the problems arose. The brakes started grinding, the check engine light came on, etc. I think the check engine light comes on every year just to remind you to get the car inspected. LOL. </p><p>So the brakes were replaced but the check engine was the lower O2 sensor and the catalytic converter. I added some stuff that promised "double your money back if it fails inspection" to the gas. I think it was from CRC. The car came with a spare O2 sensor so I had that installed. Then it came up with several codes all pointing to the O2 sensor. So I went and bought another O2 sensor, but it had a code as well indicating slow response from the O2 sensor. I was starting to think the wiring was bad. At this point I checked the collection of sensors.</p><p>The spare that came with the car DID NOT FIT the car! (It did physically)</p><p>The replacement I bought was a "universal" replacement.</p><p>So I bought an OEM exact replacement and it looked just like the original one on the left in the picture and guess what? After lots of prayer and parts swapping it worked!</p><table align="center" cellpadding="0" cellspacing="0" class="tr-caption-container" style="margin-left: auto; margin-right: auto;"><tbody><tr><td style="text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj4lIqPelkuGdsRHLlMnlu31n-6goJohQ_OfDnzkV4aaJwMv6S3ZoPgVPxiFa6MeI2Kih9y6cvPhanOd-5SKsIIVtJ1GhjV1k8aQWGrrjFieWwNIhv4A9MM-LHft4K6BHoT1uvTt6oH9ZvHhl2rBBOBa5lF5Bi76JDai9DocvohEjPYrA52MLsnuMXI4Wc/s3378/O2%20sens2.jpg" style="margin-left: auto; margin-right: auto;"><img border="0" data-original-height="1872" data-original-width="3378" height="221" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj4lIqPelkuGdsRHLlMnlu31n-6goJohQ_OfDnzkV4aaJwMv6S3ZoPgVPxiFa6MeI2Kih9y6cvPhanOd-5SKsIIVtJ1GhjV1k8aQWGrrjFieWwNIhv4A9MM-LHft4K6BHoT1uvTt6oH9ZvHhl2rBBOBa5lF5Bi76JDai9DocvohEjPYrA52MLsnuMXI4Wc/w400-h221/O2%20sens2.jpg" width="400" /></a></td></tr><tr><td class="tr-caption" style="text-align: center;">O2 sensors</td></tr></tbody></table><br /><div>Now I have a collection of O2 sensors to look at.

In all three cases all I had to do was replace the LED Backlights. There was the 65" where I disconnected part of a ribbon cable to the screen. Then there was a 55" when after taking it apart at least three times I laid it on its face to attach the back cover and somehow it ended up on its power cord that cracked the screen. Now I have a 50" TV that I have damaged one of the SIDE ribbon cables.

There are even videos of me doing that on Youtube. Well I fianlly broke down and bought a LED tester. The reason was that I had just received a second identical TV to one where I had replaced all of the LED strips and this time I did not want to buy any, but to reuse the good ones from the last TV instead. But I was in for a big surprise. Only two LEDs were bad in the last TV so I was sure I was all set to fix the new one. However in the new TV there were at least 20 bad LED's. Even with 8 good LED strips out of 10, I was still not able to fix all the lED's!! The best I could do was to leave 2 bad LED's. On top of that, as I reasembled the TV two lenses fell off of the strips, so it has to be taken back apart and repaired again!</p><p><b>The short story is that this tester works great.</b> I did have one strip that tested bad in the TV but tested good once it was removed for some reason.</p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjngcoVEcOWj0t0E91TaFsEpViO3P3qHMS7A7ZKiTqh5hW1nLeysTyUUbT4jDlL1oa2xMd9xGtQBa8MrXBwnfut08F90kQGEc6lQB3kXnYTOQOsCYkIG58sYlwXbYp94NuUsKiT3bJ-FTQ4fyh6GqTrtBcT0N5Ah64PhFstEbtsyXzLw3ul2LluFLdW/s4127/Led%20strips2.jpg" style="margin-left: 1em; margin-right: 1em;"></a><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjngcoVEcOWj0t0E91TaFsEpViO3P3qHMS7A7ZKiTqh5hW1nLeysTyUUbT4jDlL1oa2xMd9xGtQBa8MrXBwnfut08F90kQGEc6lQB3kXnYTOQOsCYkIG58sYlwXbYp94NuUsKiT3bJ-FTQ4fyh6GqTrtBcT0N5Ah64PhFstEbtsyXzLw3ul2LluFLdW/s4127/Led%20strips2.jpg" style="margin-left: 1em; margin-right: 1em;"></a><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEim4S_j06zYcItYfmvvkaw9vyboEHrDwguL8D8z_5qRPvtbcylEVTBalb-_FkRGpzpf2Mcr6pIXYukh35BbDrpJuRAJFe81py75d7F0w61081VMv2lMmsb7W0HEAZqs5eLaAO9A-8Li_Qf3eM04LI5aFmeNTAPvmjnzEPKCCtX6E5UW1mCcYQdeoOlq/s2557/LED%20tester2.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1417" data-original-width="2557" height="177" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEim4S_j06zYcItYfmvvkaw9vyboEHrDwguL8D8z_5qRPvtbcylEVTBalb-_FkRGpzpf2Mcr6pIXYukh35BbDrpJuRAJFe81py75d7F0w61081VMv2lMmsb7W0HEAZqs5eLaAO9A-8Li_Qf3eM04LI5aFmeNTAPvmjnzEPKCCtX6E5UW1mCcYQdeoOlq/s320/LED%20tester2.jpg" width="320" /></a></div></div><div><br /></div>Here is some of my LED strips that I have collected over the years that needed testing.<br /><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj4nenNARXl3-1fE9tmGT4SheM_RPjwb8Xz-TODusHbaOfLmt98xBO9c842kTFqLprTLFsHMoSxBbEJNv-hs8Mu7aapxs8ckfMfcJkmCO4wFM5JMcqvcve86Je2seqA6CixoeUFNDUpR5tXRI2D3Y0aB5NV3L1BftZbkaJ2v97StwOou8Crhk8_Gria/s3940/led%20strips.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="3940" data-original-width="1095" height="400" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj4nenNARXl3-1fE9tmGT4SheM_RPjwb8Xz-TODusHbaOfLmt98xBO9c842kTFqLprTLFsHMoSxBbEJNv-hs8Mu7aapxs8ckfMfcJkmCO4wFM5JMcqvcve86Je2seqA6CixoeUFNDUpR5tXRI2D3Y0aB5NV3L1BftZbkaJ2v97StwOou8Crhk8_Gria/w111-h400/led%20strips.jpg" width="111" /></a> </div>Here is how to test the LED strips. Basically you go + to + on each strip. Note that the strips are not always labeled correctly! The - terminals are usually just shorts. Trial and error is the quickest way to find the correct polarity. You can use a jumper to short out one end of the LED strip if you want to go positive to negative at one end of the strip. Once you replace the bad strips then test everything to make sure it works together before reasembling the TV. Sometimes the LED strip connectors have issues.<br /><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhhQvUZcgFzz8ZD6fp2DU75GYaCKQnQctmfwvTLokFqTqpwnGnbR_i5pUhchpEc8znhnfbmWwFOs3dKF4CSytnaC0Tk9aKrVd6sY--22IiGh0spcp7Wa7eI2w4jtkRwYqVemdKSR4Dmuog4q962G6xOVoNbHncDSb70Ti93BXpTnS_2dR3Xg7l6HZ1S/s4099/test%20led43.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="967" data-original-width="4099" height="75" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhhQvUZcgFzz8ZD6fp2DU75GYaCKQnQctmfwvTLokFqTqpwnGnbR_i5pUhchpEc8znhnfbmWwFOs3dKF4CSytnaC0Tk9aKrVd6sY--22IiGh0spcp7Wa7eI2w4jtkRwYqVemdKSR4Dmuog4q962G6xOVoNbHncDSb70Ti93BXpTnS_2dR3Xg7l6HZ1S/s320/test%20led43.jpg" width="320" /></a></div><br /><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgFNxchd4n_NrPivQks0Aafbs2lBLXSGbaXuRYYJGW26d33WmpsjNJHpozA_XDCZbUIVCkafnk6u9IQ1jpVz4-c1L5hPmiqqt5wnwTRaazMYtxe1qx3_-fuG70PgFMH-PC3yMz8QopSeYIZ-d-I0iMti7Pe_wPzWeutopW7iYcKacR67JA-iRzZPg3f/s3648/test%20led.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="920" data-original-width="3648" height="81" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgFNxchd4n_NrPivQks0Aafbs2lBLXSGbaXuRYYJGW26d33WmpsjNJHpozA_XDCZbUIVCkafnk6u9IQ1jpVz4-c1L5hPmiqqt5wnwTRaazMYtxe1qx3_-fuG70PgFMH-PC3yMz8QopSeYIZ-d-I0iMti7Pe_wPzWeutopW7iYcKacR67JA-iRzZPg3f/s320/test%20led.jpg" width="320" /></a></div><br /><p>This are some really burnt out LED's<br /></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhXoT1hfiVBmhtURzfQODQIROrc6x7Ss5wd6GR1GJbBW8M_4ZzxggwCfxh7fAx1rMpySTREi7rxflYQkhkPtUFkpkDHFz4KvdSMChk-Spc4fhPUtRGMS5RB897gg8oSZiLm7ro6RZDXlcYJmJt2CynV-6K83CKNDh4T3ellhtHz5uIOvzIRAno7gCZ7/s3794/test%20led%20burnt.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="823" data-original-width="3794" height="69" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhXoT1hfiVBmhtURzfQODQIROrc6x7Ss5wd6GR1GJbBW8M_4ZzxggwCfxh7fAx1rMpySTREi7rxflYQkhkPtUFkpkDHFz4KvdSMChk-Spc4fhPUtRGMS5RB897gg8oSZiLm7ro6RZDXlcYJmJt2CynV-6K83CKNDh4T3ellhtHz5uIOvzIRAno7gCZ7/s320/test%20led%20burnt.jpg" width="320" /></a></div><div class="separator" style="clear: both; text-align: center;"><br /></div><div class="separator" style="clear: both; text-align: left;">The results are not that good!

This is quite common when you reglue the lens. I do not know why so many of the lenses fell off the strips in this TV. I suspect maybe it was dropped or something. Also, I was reusing LED strips that had been removed form another TV, that process is known to loosen or even pop off the lenses.</div><div class="separator" style="clear: both; text-align: left;"><br /></div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEil1PcjYvuVhOiYsc2awNDcweQ4QwWciUmohkE6vSO2j54Mk4hJlgKFK3Tw5C2HS6mpdouUecyQU79OtJE1UkmmAYRxw9s2WWdmxX-Ilui845qJB2YkXwtoWAsmKw21S9Te6UHcfrCSC5YLXtftjtS3mPJjJDSoCRJTjjMhr8RtZ7UpmFzAl9dgpflB/s2783/Reglued.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1630" data-original-width="2783" height="187" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEil1PcjYvuVhOiYsc2awNDcweQ4QwWciUmohkE6vSO2j54Mk4hJlgKFK3Tw5C2HS6mpdouUecyQU79OtJE1UkmmAYRxw9s2WWdmxX-Ilui845qJB2YkXwtoWAsmKw21S9Te6UHcfrCSC5YLXtftjtS3mPJjJDSoCRJTjjMhr8RtZ7UpmFzAl9dgpflB/s320/Reglued.jpg" width="320" /></a></div><div><br /></div>I took it back apart and reglued three LED Lenses back in place. Then, while putting it back together, I heard another lens fall off. Then I took it apart again and found not one, but three lenses had fallen off. None of the loose lenses had been glued on before. So I glued them and put it back together again. The bad LED is on an "A" strip and I only have "B" strips that are spare. Overall it looks much better but still is not perfect. The only real solution is to replace all the LED strips with new ones....<br /><div class="separator" style="clear: both; text-align: left;"><br /></div><p></p>Bob Davishttp://www.blogger.com/profile/04602803109106077023noreply@blogger.com0tag:blogger.com,1999:blog-3584132508185165153.post-81731577902189715972023-06-05T10:45:00.007-04:002023-06-07T17:22:36.417-04:00Dynex DX-37L150A11 Replace Fluorescent Backlight tubes with LED strips<p>I hate to see newer TV's go in the garbage. Recently I was at our local firehall as they filled bin after bin with defective TV's as part of our towns cleanup. Many, if not most TV's were just having issues with the backlighting. I even brought a 55" model home to repair. Anyway, I had a 37" TV that had the older fluorescent tubes for backlighting. I watched as one, then two, then three of the tubes went out. Then the TV quit, no backlight. So I thought I would fix it with LED strips just for the fun of it.</p><p>At first I tried RGBW LED's because I had them on hand. They did not work well at all.

It has been an expensive year at that!

On top of that direct injection does not clean the intake valves that get covered in burnt oil from the PCV valve. On top of that it takes a quart of oil every 1,000 miles because of low tension piston rings that do not clean up all the oil so it gets burnt onto the rings thus cakeing them in burnt oil.</span></p><p><span>At one point the car would go into limp mode and shut down every mile or two. I really struggled to get it back home. It turns out that the HP Fuel pump had broken, the spring was completely detached, and it was pumping gas into the oil as well as leaking gas on the motor front. One of the pump mounting bolts had broken in half!!</span></p><p><span>BTW, this is how to fix an Equinox that will not start (that still has dash lights), just unplug the circled connector on the computer and then plug it back in (This also erases all problem codes):</span></p><p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi2jgdE8dxo0Fw9NEMRgRS4sMKQF5g75MmOZQHYxnKXWgP9GKB7sFiNb5YY3_px0Qz6kKQ_49HleL2c8spj66am1gddkcPB6IT3CrbQ9_lC_SzvgUP6g_6glhjFm1HJM4mxp-vrR-MiZ02smAOFluP952Qzw0uTF7I-FBV2-DGq3WGt1EKtOwXpF3IY/s2080/EQ%20CPU-e.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="936" data-original-width="2080" height="144" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi2jgdE8dxo0Fw9NEMRgRS4sMKQF5g75MmOZQHYxnKXWgP9GKB7sFiNb5YY3_px0Qz6kKQ_49HleL2c8spj66am1gddkcPB6IT3CrbQ9_lC_SzvgUP6g_6glhjFm1HJM4mxp-vrR-MiZ02smAOFluP952Qzw0uTF7I-FBV2-DGq3WGt1EKtOwXpF3IY/s320/EQ%20CPU-e.jpg" width="320" /></a></div><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjZmkQ0Ifv_4rTxdEH_XImfR76fZEqBIQGtvNFtNUidJmcoOvrjSEQgoqNCh9rOBTarw2DamyJCKJ5duZkmVtISmOYGP2LpRRQgThqPf-R6DzNFs7-RDpYKTmV_mb4fn7OOrgWEwf7Et-nioe9nZLNXEibOritdTzAUmy2y4GxaNBGog0ESwZllWics/s4160/EQ%20CPU.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1872" data-original-width="4160" height="144" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjZmkQ0Ifv_4rTxdEH_XImfR76fZEqBIQGtvNFtNUidJmcoOvrjSEQgoqNCh9rOBTarw2DamyJCKJ5duZkmVtISmOYGP2LpRRQgThqPf-R6DzNFs7-RDpYKTmV_mb4fn7OOrgWEwf7Et-nioe9nZLNXEibOritdTzAUmy2y4GxaNBGog0ESwZllWics/s320/EQ%20CPU.jpg" width="320" /></a></div><br /><span>Since I wrote this it developed <b>another</b> issue. It would stall sometimes when you stop and sometimes when you almost stop to make a turn. Then it went into limp mode and would not leave first gear. So I added some Lucas transmission fix and it has not stalled since then. It does still sometimes have a rough shift down so I think it needs to have the transmission fluid changed.<br /></span><p></p><p><span><br /></span></p>Bob Davishttp://www.blogger.com/profile/04602803109106077023noreply@blogger.com0tag:blogger.com,1999:blog-3584132508185165153.post-74233665046069521272023-06-01T09:20:00.006-04:002024-03-01T09:03:51.200-05:00JBL SB2 Subwofer Speaker Repair<p> I recently repaired some JBL SB2 subwoofers.

The TV is so huge that there was almost not enough room where I was working on it. So I stacked everything behind it as I took them out so they would go back in in the same order. The screen was attached to the black plastic pieces so I tokk them out together, but that makes it very difficult to put it back together.

There is a old blog post on it. For some reason the bottom element quit working so I thought i would fix it. It turned out that there had been a water leak for a long time. The area was completely rusted out so I did not dare touch it. My wife wanted a 40 gallon heater but they are 21" in diameter and would not fit in the space available. However I discovered that there is a narrow 18" diameter 40 gallon water heater that is available at Lowes.</p><p>The 12 year old water heater.

They came equiped with 500 watt light bulbs. That means that you can only have three of them on a typical 120 volt circuit. So I thought I would retrofit them with some LED lights. But a direct replacement LED light is $100 each! Then I came up with a retrofit that can fit almost any light from a PAR38 sized bulb. Now they are not as bright, typically 1000 to 2000 lumens. The 500 watt lights are around 6000 lumens! But the LED lights are still very bright, even blinding to look at.</p><p>All you need for the retrofit is a metal strap, it needs to be strong, I have doubled up some of the wimpy straps to get enough strength. Then you need a 1000 watt ceramic socket.
