Hello,
I have a Yamaha receiver that does not power up. Does absolutely nothing. I have this far changed the common fault capacitor C405 to another 22nf 650V capacitor but that does not seem to help.
Testing the voltages I have 16 volts on C411, 5v standby is also present(excactly 5v). And AC input 230V is also present.
Only problem I have is that from the transformer leads I do not get 230V output at all. When I measure plus and - on D408 the multimeter shows only 3 Volts(testpointts marked on picture).
What would be the bad component here? What should I look for?
I am not really that familiar with mains voltage rectifying procedures.
