YAMAHA RX-V450 Nem indul,semmilyen próbálkozásra se reagál.
Sziasztok!Fent említett erősítő,még várakozás,hideg indítás,bármilyen praktikára sem hajlandó bekapcsolni.Még nem érkezett meg hozzám,de korábban még elindult egy-kétszer,de most már abszolút nem csinál semmit.Olvasgattam itt mások eseteit,itt is kondi lesz valószínű,vagy még mást is tönkre vághatott?Csak az érdekelne,hogy elérhető-e hozzá minden olyan alkatrész amit esetleg cserélni kell.Válaszaitokat,segítségetek előre is köszönöm!Üdv Sakee.
YAMAHA stagepas 400 működtetése agregátorról.
Üdv Mindekinek!
A címben szereplő erősítőt kellene működtetni egy bemutatón olyan helyen, ahol nincs hálózati feszültség.
A kérdésem a következő: merjem agregátorról működtetni a meghibásodás veszélye nélkül?
Milyen megbizható megoldásokat tudnátok ajánlani az erősítő müködtetésére ?
Egy erősítő már tönkrement agregátoros müködtetéssel, bár nem bizonyitott, hogy a meghibásodás összefügg az agregátoros működéssel.
A javaslatokat előre is köszönöm.

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?
