Sziasztok, adott ez az erősítő, olyat tesz, hogy teljesen megnémult, tápfeszek +-34volt megvan a végtranyókon, nem melegszik, relé kattan bekapcs után, de nem igazodok ki a panelen, a relé érintkezőin sincs már táp, egy rajza volna-e valakinek, köszi.
Szervusztok!
Van egy STR DE 875-ös erősítő nálam aminek kitörték az antennabemenetét - sajnos - 4 SMD alkatrésszel együtt. Rengeteg rajzot találtam hozzá, de a tunert egyik sem részletezi, csak egy blokséma van mindegyikben. A part. száma 1-693-539-21 vagy ...540-21. Ha valaki tudna közelebbit erről megköszönném nagyon.
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!
Ennek a sony-nak süket a rádió része, még sistergés sem hallható. A cd kifogástalanul működik, lejátszik mindent. Milyen feszültségeket kéne tudni mérni a tuner lábain?
