Yamaha psr-s500 szintetizátor - kijelző egyik fele sötét - Megoldva
Sziasztok! Yamaha psr-s500-as szinti kijelzőjének egyik fele ne működik. Minden egyéb működik rajta, kontrasztot tudom állítani viszont a jobb oldala a kijelzőnek ha feltekerem a kontrasztot teljesen elsötétül ha leveszem a kontrasztot teljesen világos. Segítségeteket kérném, hogy hogyan tudnám megállapítani hogy a kijelzővel vagy a vezérléssel van a gond? Üdv.: Norbi
YAMAHA RX-V367 nem szól, vége megy
Sziasztok! Az erősítő Yamaha RX-V367 kapcsoló ic-je nem működik, rendeltem egy másikat és kicseréltem, de sajnos minden maradt a régiben. A tápok jók és az érdekessége az, hogy a bekapcsoláskor egy pillanatra van adatforgalom, de a későbbiekben hiába utasítom bármire /bemenetválasztás/ semmi sincs. Tuner üzemben a bemeneten van jel a kimenet meg nulla. A gyári rezetet megcsináltam. Gondolván hátha már valaki végigjárta az áramköreit és egy ihletet adva tudna segíteni. Köszi
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?
