Hi sir, Leandro from Uruguay! Can you explain a bit more about the V of the integrated chip? And show the lights please! I wanna repair the same TV and 😃
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).
After I will try to find the solution searching searching searching after I find that IC number get it circuit diagram then I will start the modification backlight voltage
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.
hi sir my led's on the strip is oky if i test one by one but if switch on the tv the backlights just dim goes on and of quick ,does it mean i have the same problem
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.
