Stage Line STA 502 erősítő egyik oldal hibás. Kapcsolási rajzot keresek
Üdv mindenkinek,
az erősítőnek az egyik oldala elszállt és valaki orvosolta
a problémát kicserélt mindent ami szerinte rossz volt
viszont elkövetett egy súlyos hibát  A 2SA 1694 és
a 2SC 4467 helyett BD 29-250 használt.
Esősorban rajzot keresnék a készülékhez.
Ennek hiányában is meg tudom javítani de szeretném
látni a kapcsolást,már kerestem a neten de eddig sikertelenül
talán valakinek meg van ennek az erősítőnek a rajza.
Előre is köszönöm a segítségeteket.
 
Yamaha CDX-590 laser adjustments?
I have a Yamaha CDX-590 CD player and it skips on some CDs - original CDs, these CDs play without problems on my other CD players. I have changed the laser unit (KSS-210A) but this didn't solve the problem. When I turn the player upside down, it plays the problematic CDs without a problem. That's why I think the laser needs adjustment. I have only a service manual for the CDX-493/593 but they should be very similar to the CDX-590. It seems that the adjustments are done via "test mode" of the CDX-590, unfortunately there is not much information, how to exactly, in the service manual. Here is a picture of the PCB. http://www.volny.cz/hwtest/PCB.JPG Here are the "test mode" sections of the service manual. http://www.volny.cz/hwtest/TM1.GIF http://www.volny.cz/hwtest/TM2.GIF In "test mode" I have tried Auto adjustment mode 1, 2, 3, but I don't know if it should work fully automatic without any intervention or when the mode is fineshed and I can proceed to the next one. So I activated mode 1, waited a while, activated mode 2, waited a while, activated mode 3, then exited test mode. It didn't help. Mode 1 - only a short blink of two horizontal dashes on the display and thats it Mode 2 - started "play" without sound from a strange time 99:00 (the test CD is not so long), after a while it skips to another time, "plays" a while, then skips back and "plays" and so on, I left it about an hour and it was still going on Mode 3 - seems to be very short as mode 1 I think I'm missing something ... Maybe someone did this or even serviced Yamahas in an official service and can provide information how to adjust the laser? Or maybe the problem is not the laser?
NIKKO R400 Kapcsolási rajz vagy szerviz manuált keresek
Hozzám került egy Nikko R400 rádió erősítő.Hibás volt az STK4171X. Cseréltem, de a tápellátásban van hiba. Jól jönne egy rajz, hogy tudjam a feszültség értékeket. Minden ötlet jól jön.
