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 TX-NR1007 házimozi erősítő nem szólal meg
Sziasztok! A készülék kijelzője működik, funkciók állíthatók, a rádió rész is hangolható. A végfok kimenetén lévő relék viszont nem kapcsolnak be, a végfokra már nem kerül hangjel, így nem is szól a készülék egyetlen kimenete sem. Van benne egy jó nagy HDMI panel, nagyon sok alkatrésszel, ezen mértem tápokat, amik valószínűleg jók voltak. A készüléket Reseteltem, de nem változott semmi sem. A kijelzőn nem jelennek meg a hangszórókkal kapcsolatos ikonok sem.  Ebben a készülékben is ez a HDMI panel okozhatja a készülék problémáit? Valakinek van javítási tapasztalata benne?
ONKYO TX-SR307 nincs hang
Sziasztok,

Onkyo TX SR307-es HDMI-s erősítőnek nincs hangja. Bekapcsol, minden funkció működik rajta de nem jön ki rajta hang.

A HDMI-DSP panelen néztem az IC-ket, egyik sem BGA tokozású, mind SMD. Gondoltam, ezek nem forrasztották ki magukat mint a BGA-s társaik.

Kicseréltem ezen a panelen az SMD elkókat, a helyzet nem változott. 

Érdemes újra forrasztanom az SMD DSP ic-t?

Valakinek hasonló helyzet?

(egy érdekesség: ha a B hangfal kimenetre kötök hangfalat és a hangerőt max-ra teszem halkan ugyan de jön ki hang az erősítőből)
