By checking with a digimer, I found that the Schottky Diode in the power supply module is defective. The question is why it burned and whether it was the only defective one. Thank you for your help.

Thanks to the colleagues who helped me solve my Sony Tv. I replaced the Schottky Diode and two electrolytes 470 µF and 1000 µF in the diode circuit and the tv worked. Greeting
P.S. I am an older generation of RTV mechanics and I have not been active for a long time. Electronics is more of a hobby for me.

Hi!
There is some shottky diode on this board. Replace the defective, and also replace the elektrolyt capacitors (105C Low ESR).
