AUO 39' panel Vertical bar/ freezing picture Solved/panel repair

[planb]

Thanks for your time and efforts to share your expert knowledge.

Your technique seem working sometimes and fair enough but VGH voltage is not an alternating pulse but a constant 30V DC voltage and likewise VGL is a constant -9V DC voltage and not an alternating pulse. So my question is, why connect constant DC voltages to LC1 and LC2 which supposed to work but with alternating PWM signals, in this case pulsating 30V to -9V DC voltages with 3s duty cycle from the level shifter chip? And secondly, how does by passing the level shifter chip LC1 and LC2 PWM signals solve the problem, if it's caused but by the faulty gate electronics in the glass panel and not by the level shifter chip on the driver or source board?

Sir when I done this procedure again vertical bars appear can you explain about vss point cutting

[sureshv]

Super sir but same work paniten but 20 minite after jumping agin picture sir

[vaikundaboopathi]

Sir, LC2 ku VGH jamber pannanuma Illa AVDD voltage jamber pannanuma sir.

[tusiimegeofry]

I have the same problem but the levelshifter ic is to hot, and the vgl voltage keeps increasing and decreasing
