Onkyo DX-7333 CD player sometimes doesn't recognize CDs
I have a Onkyo DX-7333 CD player, which sometimes doesn't recognize CDs. I don't think it's a laser pickup (KSS-213C) problem, because when it recognizes the CD, it plays it without a problem, even very scratched ones. The next thing is, it should play CD-RWs, but it doesn't even recognize them. I think it needs adjustment There are two pots on the main PCB - Focus Gain R123 and Focus Offset R112. Also there are two test points: TP1 4 pins, first pair labelled Tracking Gain, second pair Focus Gain TP2 2 pins labelled RF Out and VC But in the service manual is no description, what should be measured on the test points and how to set Focus Gain and Focus Offset. In the attachment is a cut out from the schematic, where the test points and adjustment pots are. Please if someone knows, how to?
Onkyo TX7830-nel a hangerogomb forgatasara a hangszorok membranjai ki/be mozdulnak.
Sziasztok. Van ez az Onkyo Tx7830 radios erositom. Mukodik rendesen, de ha a hangerogombot (jel nelkul) gyorsan forgatom fel vagy le, a melyhangszorok membranjai kifele ill. befele mozdulnak. He elegge gyorsan forgatom, a vedelem le is tilt. Lassu forgatasnal ez a jelenseg nem jon elo. Van a Tanyan s.m. rola, nezegettem is, de nem latom a kapcsolatot a hangero novelese v. csokkentese es a membranok mozgasa kozt. A hangeropotmeter es a meghajto ic. bemenete kozott van egy muveleti erosito, es ez galvanikusan le van valasztva ugy a potmeterrol, mint a meghajto ic-rol.  Ha valakinek lenne valami konstruktiv otlete, ne tartsa magaban. Koszonom.
ONKYO A-8630 hálózati trafó
Jó napot mindenkinek! A típus A-8630. Letakarták és úgy üzemeltették.Kiverte a hálózati biztosítékot.A tulaj átkötötte,és eleinte elindult. Most már csak kiveri a biztosítékot.Ha lekötöm a hálózati trafó szekunder oldalát nem változik semmi.Ha a trafó egyik bemeneti ágát kikötöm nem olvad ki a biztosíték.Szerintem rossz a trafó,de már nem gyártják.Tud-e valaki valamilyen beszerzési forrást? dínó
Onkyo tx-sr500 nem jön ki belőle hang
Hozzám került egy Onkyo TX-SR500 erősítő, nem jön ki belőle hang. Bekapcsol, kezelőfunkciók működnek, de hangot sehogy nem ad. Oszciloszkóp nélkül nehéz...Tápok szerintem megvannak mindenütt. Valaki nem találkozott ilyen hibával? Gyanakszom a bemenet választó IC-re.
