Two of the LCD monitors that I purchased really cheaply on EBay had bad inverters. I had never successfully fixed a bad inverter before, even after trying to fix them a lot. But this time I was in luck, every one of the bad inverters had a little silver 22 uF capacitor that was bad. Replace that capacitor and the inverter works! You can optionally replace the power supply filter cap, it was bad but did not appear to affect the monitor. Below is a picture of the inverters with the capacitors replaced. You can use a 10 uF at 25 volts to replace the bad capacitor.
Next I needed some 12 volt 4 or 5 amp power supplies for these monitors. They sell for around $25 on EBay. That is unless you look for universal LCD monitor AC adapters. They sell for $10, and the text says they support the VE170 screens!
