Sziasztok
Van egy Sony cd játszó aminek sajnos nem lelni a rajzát sehol és a 591-es abszolut más belvilágú. Sajnos nem forgatja a lemezt a motor meg jó. a lézer próbálkozik. a motort egy LA6520 ic hajtja. Tud valaki ajánlani egy másik típust amiben szintén ez az ic dolgozik, hogy megnézhessem a vezérlés módját. Az ic adatlapja már megvan.
Köszönöm Laci
Hi!
Az említett erősítő megadta magát, még a relé sem húz be.
Szervízoldalakon láttam a tipikus hibajavítási ötletek között ezt a "relé nem (sem) húz be" problémát, csak sajnos nem férek hozzá.
Valakinek esetleg ötlete, tapasztalata?
Nagyon köszi!
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?

Üdv!
Ismét megpróbálom, hátha... Sajnos betörték (kijelző, minden más OK), ha lenne valakinek bontott ilyen készüléke, vevő lennék a plexijére, vagy a komplett előlapra: http://www.kephost.com/view3.php?filename=56lgkrzav1uuxvx7gxz2.jpg
