Yamaha RX-V595ARDS bekapcsolás után azonnal kikapcsol.
Sziasztok!
 A fenti Yamaha tuner erősítő St.by-ból való bekapcsoláskor azonnal kikapcsol. Ha egy soros ellenással sorba kötöm, (kb. 130V kerül a gépre) kifogástalanul működik. Így szoktam indítani a zárlat-gyanús készülékeket. A tápok jók (látszólag), brumm minimális. Ahogy a működő készülékre rákapcsolom a direkt tápot (220V), ismét azonnal kikapcsol. A trafó is látszólag jó, mert ha 220V ot kapcsolok rá, alig van áramfelvétele. Találkozott már valaki hasonlóval?
Köszönettel:

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?
Yamaha AST-C10 bekapcsolás után búg ( MEGOLDVA )
ÜDVÖZLET MINDENKINEK.
A fent nevezett készülék egy mini hifi. Olyan hibával került hozzám,hogy nem szól. Ezt a hibát megjavítottam,/ a hangszóró védelem reléje volt oxidos/. Most bekapcsolás után mikor a relé behúz, búgó hang hallatszik a hangszóróból, illetve a fejhallgató kimeneten bármelyik bemeneti forrás kiválasztásánál. Sajnos javítás előtt nem próbáltam ki a fejhallgató kimenetet. A készüléknek van még egy hibája. Működés közben néha elhalványodik ,vibrál a kijelző világítása,illetve bekapcsoláskor kétszer , háromszor ki-be kapcsol a védelem reléje.
A segítségeket előre is köszönöm.

SZIASZTOK !

KÖSZÖNÖM MINDENKINEK A TIPPEKET, TANÁCSOKAT, DE KÉRLEK BENNETEKET, HOGY MIATTAM NE VESSZETEK ÖSSZE !!!

Üdv  Misi
