I have damaged three TV's in a row while trying to fix them.

I am batting three in a row for destroying TV's while trying to fix them.  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.  I had them all tucked in but when I put on the bezel two of the side cables came out and were damaged by the bezel.

This picture shows the side ribbon cables (The screen is on its other side).  The cables loop around and are only about 3/8" long.  They tuck into spaces that are alloted for them.

The result of the damage is the top left side of the screen is out.  If I play with the damaged ribon cable it starts working for a few minutes.

The 65" TV that I accidently disconnected part of a ribbon cable, then fixed it with a clip, is still working!
