Hi, excellent video. Would this also work on overheating issue on TP MS338 PC822 (LED backlight voltage is 151 V and LED backlight transformer gets up to 65 deg C).

My Smart TV Backlight output shows only 55 volt, how ? 55v is only enough? After releasing standby only the voltage increase? The TV is in standby mode, not releasing.

black light burned out, which one is compatible? I didn't find it here in Brazil.

Dear, I am from Uruguay I do not see correctly the value of the resistor ..? Or if someone knows? Thanks a lot..

4.7k, 3.3k, 2.2k anyone ic pin no 5 make ground, low resistance value you can make more reducing voltage

@bijugeorgestvtips 3 жыл бұрын

2.2k you can reduce more than 20 volt

1 second power coming ? = backlight problem. Totally zero means PCB problem

and what is the resistor color code

4.7 k reducing 5 v, 2.2k reducing 10 volt( voltage making low )

@BentonRepairs Жыл бұрын

whats this do , but reduce the back light voltage ? which means a dimmer picture , how's that even a fix for the backlight that's only mod for a working backlight, have you looked at a circuit diagram for this board , cause the chip your calling a voltage regulator is a dual op amp putting a pull down 2.2k resistor on pin 5 of the 01358the positive side to ground of the op amp input , seems like a very odd solution unless something else is wrong , is this to stop the leds blowing in which case you should explain and title the video accordingly because its not fixing the backlight but perhaps it may reduce the LED voltage , and yea you really need to work on your English or put in some subtitles. TP MS3458 pc757 is virtually the same with slightly different component layout. I would give it a title like " Reducing the backlight voltage on TP MS338 PC821" and im not convinced its the best way to go about it , an interesting hack though.
