Re: Samsung un58tu7000fxza - Power cycles with no picture, only backlight
Could be less resistance or something which is causing voltage drops as is pulled next to VSS -10V path 23

I have isolated path 22 of the flexi using tape . +25V is going through my wire only. I have soldered to the VGH testing point on LCD PCB and MB's soldering point next to the molex connector.Leave a comment:

It was not actually a video. The idea of linking LCD panel directly with MB described earlier gave me a clue that could be a possibility of current leak between VGH 25V and VSS -10 placed next to each other. Cheebster's post #71 and the link he found was crucial. I haven't removed anything from LCD PCB panel.Leave a comment:

Hi everyone.Just wanna say that mine is working too. I have done taping track 22 which is feeding LCD pannel with 25V , then crossed VGH located on pannel's PCB with MB's 25V directly bypassing molex ribbon using random wire. Havent use the resistor as wasn't necessary in my case. TV turns on every time. Thanks for detailed explanation.Leave a comment:
