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?

Hughes & Kettner Target 244 + 5 keverő pár csatornája vacakol MEGOLDÓDOTT!!!
Kedves Kollégák! Szereztem egy Hughes & Kettner Target 244 + 5 típusú keverőt. Kb 5 csatornán - különböző mértékben - a következő hibajelenség van: Bedugok egy mikrofont...nincs hang... mozgatom az XLR-csatit VAGY tekergetem a Gain-t, Vagy hangosabbann beleszólok a mikrofonba és megjön a hang. Hasonló jelenség a Line Jack-ről is produkálható. A Jack-ek (line és insert) a csatornapanelre van ültetve, az XLR vezetékkel van bekötve. Tapasztalt már Valamelyikőtök ilyet??? Esetleg egy kapcsolási rajz??? (nem tudom, hogy a Jack-ek kapcsolója van-e használva) Felhasználói leírásnak is örülnék Előre is köszönök minden segítséget!!! stonhy
