Very interesting video I ever seen on youtube. About drop voltage ⚡.Vgh vgl. Well explained. And very short video but very useful tips. Carry on guys for your great works. Thumbs 👆
I've watch many LCD video tutorials on how to solve this kind of problem but nothing mentioned about COF being replace guess they don't have the machine that you have to do the right job amazing.
Thanks for your time and efforts to share your expert knowledge. Your technique seems 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?
Loving your videos, if I understand this tracks correctly, VGL and vgh goes to the cofs directly. What if the ckv tracks, please do the video of the ckv tracks
Great video! A compilation of nasty, complicated issues that requires the touch of a genius to resolve. I love your meticulous workplace and neat presentation. Do you provide training? If so, I'd like to visit you if the world gets better.
Thanks for your amazing video,sir what about voff it becomes high in on switch and it latter goes down the voltage, what is the possible cause??? Thanks and more power to you
Hi can you help me vgh and vgl no voltage or drop voltage newbie tech and still learning about led TV.. it only shows the logo for a minute then it will auto turn off ... Custer said he try to clean the screen with alcohol maybe there where some spoil goose to the panel... Haven't open the panel yet seems backlight is good since it's lighting up for a minute..thanks
The connections and bypass does not show a professionalism, could it cause a short circuit. Is there another method to use to looks better aesthetically?
In my Onida tv after power on V ON is going down from 16v to 98mV , all remaining voltages are stable, capacitor looks good. Now how can I check issues?
Can you help me.vestel led 32 inch picture is green at first than slowly turns in to white n the midle green (left) white(in the midle) and green on the right all verticaly .all voltages are present 29v15v7.5v 0,6v
There is a Daewoo TV with Slack that works without any problems. The image suddenly turns black after an hour of work, and dotted lines appear on page 3 of several times. Some cases reset and continue in two parts, some cases are off-key but some cases are on-key but not the image. There are two modes of the green light, which indicates that the TV is on. In the last two cases, we have to disconnect the two electrical outlets and then turn on the electricity to return to normal. please help There are several Daewoo TVs that have this problem This model is 42F 4100
@@VcoreLC thanks. After injecting 15v voltage onto Avdd there was different affect on the screen then cof started smoking. Too bad. Another tv in the rubbish.

I have Avdd 7.4v only. Should be 15v. What is usual cause of AVdd low problem?
AVDD switching mosfet/Capacitors/ IC
