Philips 55PFL6008K/12 QFU1.2E dead

[sopik78]

Hello good people,

please help me with TV Philips 55PFL556008K/12 chassis QFU1.2E with no reaction to switch on or any key on RC. No LED flashing.

On main board I can read 1.1V, 1.5V, 3.4V, 5V, 12.2V, when plugged to AC, the power consumption starts from 0W to about 20W, then drops to 16W and after while to 0W. CPU is warming up a little bit.

I guess the power supply board is OK and problem is on main board.

What should I check?

The manin board code is 3104 303 54946 B, 3104 313 66186 B

According to page 58 you appear to have all the voltages. Is there absolutely no other signs of life? Is the digital audio led output on the mainboard on?
There does appear to be an awful lot of fuses shown in the schematics that would be worth checking out.

Yes, digital audio LED lights for a while when plugged in AC and that voltage rails start up.
