Bush tv LT26MC1A with a 715T2907-2 psu

[vinceroger]

Hi guys i have a bush lcd tv i was given im struggling with repairing the psu basically the main filter cap has 336v dc but no voltages on the secondary side i have the psu on the bench im not sure if i need to jump any pins too test the secondary voltages can someone look at the schematic and advise me many thanks

What is main filter cap, C920?

IC901 pin8 must have Vcc, it's from T901 feedback winding.

What IC902 pin2 has?

check +5V presence then activate supply by putting some resistor between PS_ON and +5V ()small, like below 100ohm you already have the 10kohm).
seems like that higher side psu is outputting the standby voltage.
if no +5V, then dig for this standby voltage. you can put some load on +12/+24v outputs or just use the TV boards for this
IC902 is my main suspect, or something around him
