Sony DTC 790 DAT magnó befűz, de nem indul a lejátszás.
Befűzéskor felpörög a fej, azután leáll, CAUTION hibajelzéssel.
A kazettát is csak úgy lehet kivenni, ha ki és bekapcsolom.
A kazettaérzékelő kapcsoló, a két motor, elektromágnesek, tápok ellenőrizve.
Rajzot a Tanyáról letöltöttem.
Valaki ismeri, vagy javított ilyet?

Sziasztok,
Egy elhalálozott (több IC rövidzáras lett) alaplap helyett keresek egy jót a Sony MHC-V11 erősítős hangládához.
Gyártó szám: 988522300 vagy 988520889
Fut még ilyen néven: 40bhx2241-maf2g
Köszönöm,
István

Üdv mindenkinek!
Van valakinek ilyen autórádióhoz bontott előlapja? A hangerő mikrokapcsolót kellene kicserélni, de ezek a leddel egyben vannak, és igen borsosnak tűnik az ára.
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?
