Sziasztok!
A fenti erősítő az eredeti távval nem működik, csak egy-két funkció. A táv egyébként él, ad jelet. Egy másik, eredeti Sony Audio távval is ugyanez a helyzet, csak pár funkció működik, itt azonban már több: hangerő + és -, muting, kikapcsolás.
Tudna valaki tanácsot adni?
Köszönettel:
Attila
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!
A fenti tunerben van egy 5 lábú fekete téglatest alakú alkatrész. Ez van ráírva: TOKO AR50Hx.
Úgy tűnik, hogy belül kh-s, mert ha megnyomom torzít a rádió. Kérdésem, hogy mi lehet ez és mivel tudnám helyettesíteni? Gondolom valamilyen szűrő lehet, de milyen? Az IC-t sem sikerült beazonosítani, rajz alapján okosabb lennék, de mindenhol csak a blokkvázlata szerepel.
Üdv.
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
