Friends Sony STR DH130 goes into protection mode soon after turning on. It works for a second then can hear loud pops from speakers.
I've tried the suggested methods to fix but nothing works. Correct impedance speakers. Speakers wired correct. Good ventilation.
I've tested the output transistors in circuit and I don't see anything unusual. I may pull them to test but will wait for advice here. I also measure
about 57 volts on the emitter resistors. Seems high to me. Anyone?

Sziasztok
Van egy Sony Házi Mozi Erősítő amiben a készenléti trafó nem működik de sajna sehol sem találom hogy a szekunder feszültsége mennyi lehet se a rajzon nincsen megadva sem a part listában sem a neten trafó szám alapján nem találok róla adatokat úgy látom eléggé titok övezi hogy a Sony nem veri nagydobra ennek az értékét .
Én 12V tippelek de inkább kérdezek mint le égessem a vezérlést.
