Kaptam egy Onkyo TX-SR 605 tip. erősítőt, amely nem szólal meg. Minden funkciója működik. A bemeneteket lehet rajta kapcsolni, a reset-re sem változott. A kimeneti relék is kapcsolnak. Ha valaki tud adjon tippet a hiba behatárolásához. Előre is köszönöm.
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?
Üdv' Mindenkinek. Kezelőn stby 5V megvan, stby gombon is. A relét, mi bekapcsolja a cuccot egy tranzisztor kapcsolná, aminek a bázisa valahonnan arról a digitális förmedvény panelról jön, ami a mindenféle av és egyéb dolgokat is kapcsolgatja. Ha a relé meghúz, villanyok megjönnek, de továbbra is agyhalott. Itt feladtam.
A cucc pesti.
Ha akad, ki elmolyolna vele, küldjön privátban egy telefonszámot és összehozom a gazdival.
Can anyone help me with this service manual?
I have a unit with damaged Ethernet port.
