Hello everyone, I would like to ask some help repairing this Panasonic TV.
The symptoms are the following:
TV turns on, power LED turns green. The display shows a faint screen with very dim backlight, then turns black, power LED starts flashing red indefinetly.
The PSU outputs two voltages: 5.5V and 16V


5.5V is present, while 16v is not on the output pin.
I started looking for for short, not found any.
Damaged components like capactirs or diodes, did not find any either.
So I started measuring around the board, tracking back the missing 16v.

As you can see, the NCP1234 has the High voltage input, but nothing on the drive output.
The Mosfets has voltages on the source and gate, but nothing on the drain.
I managed to find the schematics of the TV, I started examining it but I'm pretty new to these SMPS PSUs.
Can you please point me the right direction and help me repair this board?
I couldn't find any cheap ones either to just replace, also I would like to learn repair these kind of circuits too.
