Hello,
I have a Philips PUS6501 TV that I got as defective. The TV has no picture. I first tested the power supply and made a short circuit during the measurement on Q8101 between D and S. Therefore, the Q8102 and resistor R8101 burned out, which I changed. After that I went to test the LED backlight and one LED was burned out on each strip. Now I doubt that the LED backlight was a major malfunction and that the power supply was good.
After repairing the LED backlight, the TV did not work again. I managed to turn it on when I was measuring the voltages on the power supply with an instrument, but it turned on so that initially the LED backlight flashed for a few seconds and the TV turned on. Then everything worked, the TV could be turned on and off, everything worked. After that I unplugged it overnight and it didn't work again, it couldn't turn on.
Ambilight lights up but there is no picture.
On schematic I circled with red on page 4 which part I changed and the one I shorted.
Does anyone know what else needs to be checked or what is wrong?
