Üdv mindenkinek! Ehhez a kis Sony erősítőhöz keresnék Service Manualt,vagy egyéb bármilyen doksit.
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

Sziasztok,
A fent említett erősítő hibakeresésében kérnék segítséget.
Végfok STK4161II
Táp +-41V szkóppal nézve tiszta.
Passzív elemeket jónak mérem táp után +-15V rendben van előersítőnél zárlatot nem mérek.
Végfok nélkül védelem nem tílt a relé kapcsol.
Végfok berakása után a két kimeneten tápfesz. Több végfokot is próbáltam.
Raktam bele STK4191V is mert ennek a tápfesze +-53V lábkiosztása ugyan az hátha kicsit megszalatt a tápfesz. de a jelenség ugyan az.
Annyit vettem észre hogyha a 8 as lábat lebegtetem akkor a védelem nem tilt de hangot nem tudtam kicsikarni belőle.
jelgenerátorom sajnos még nincs.
Ha valakinek van ötlete azt megköszönném.
Üdv.:
Gy
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?
