Default VESTEL 17IPS71 - Quadro TV

Hello, i have this PSU 17IPS71 that have no other voltages except 12V on CN4 connector. I found that this board have many faults and i read this threadbut did not find any help.
What i try to do:
replace U202 (FAN6300)
replace LED driver (MP3394)

All caps look ok. I check all diodes and they are ok. On D22, D24 and D26 i have 12V.

On D11, D13 and D15 i got 30V.
On D27 i have 30V on bot sides (the diode is ok, not shorted)

So on output connector (CN4) i only get 12V no 5V.
Also on IR i get 3.3V (no 5V)
