Game king lcd blacks out after warm up

[Lizardking2000]

I have a gameking with a tovis LTG-1932UR LCD. After warm up the screen blacks out but everything including touchscreen still works (has green light in lower right quadrant). After reset it comes back on for a short time depending how much it has warmed up is how long it will stay on. I’ve checked all fans and they are working. I’ve even put a fan in cabinet but no luck. I’ve checked all caps but they appear good (visual). HELP!!!!!!

Sounds to me like the backlighting is failing when it warms up. try a new inverter first, if that does not fix the problem, then I would say your ccfl's are bad and need to be replaced or converted to LED.

Thanks! Any idea what the output voltage should be from the inverter?
