Long story short, I'm putting together a receiver, from two receivers. Both had different issues. One missing the power supply, the other had a corroded HDMI board.
The power supply does not work, it had two IC's blown(very visible), D901/D902 and I have found a bad resistor.
I have replaced two blown ICs and resistor, but it still won't power on.
I don't even have standby voltage.
I measure 334V, at the transformer TF93's #7 pin.
Q901 FET is getting 334V.
The ICs, are not getting VCC at all.
D914 zener diode shows .718V one way, but meter is not beeping. That is normal?
Any help would be appreciated.
