5 amp 125v fuse blown on Sony STR-DE197 Receiver

SOURCE: sony str-de845 Powers up, relay clicks, fuses BLOW!

This condition, may be produced by defective components (Q506, Q507). you can remove those transistor, replace the fuses, power-on and wait for relays click. if the fuses not blown again, them replace both transistor.

SOURCE: I have a Sony STR-D565 Receiver. I bought new

I resently hooked up my sony std d 565 reciever for 5.1 speakers and I keep hearing beeping, what is wrong?

SOURCE: Blows main fuse when power is turned on

Shorted power supply/module is most likely problem.

SOURCE: I have a Sony STR-D965 receiver that has worked

its a common problem when the amplifier outputs are shorted and need to be replaced. put tinfoil on the fuses and watch it smoke
