Did you replace all the caps that were the same as the bad ones? You may be able to find a replacement power supply if you Google around. Search Youtube for switching power supply repair guides: http://www.youtube.com/watch?v=TxGgUiUo1F4Comment

Take pics of the boards using the manage attachments option and make sure they are of high quality. We need to check the voltages going out the power supply to make sure there are no other problems.

I acquired a free 50” TV. IT is a Sharp LC50LE752E. It does not show a picture and has no backlight, although the indicator light turns blue meaning it has turned on.

However after the screen swap the Touch and Pen feature still doesn't work, neither on Windows 11 nor in Linux (tested with various distros).

Hello Community,
Would welcome any help on getting a service manaula for the above model (Phillips 75PUS6754/12) TV or anything similar.
Picture intermittently works fine for a day or a minuite then goes off, but backlights appear to remain on.

Thanks in advance,
