YAMAHA RX-V457 erősítő tápegységében alkatrész azonosítása.
Sziasztok! Nevezett erősítő került hozzám, tápegység hibával. Nemrég járt szervizben, de pár hét után ismét megadta magát. Láthatólag két alkatrészt cseréltek benne: R419/D405 Most ugyanez az ellenállás égett szét. A zener jó, viszont nem tudom az eredeti jelölése mit takarhat. Helyette Z10M lett berakva (ez sem sokat mond) Jó lenne konkrétan tudni, mik lehettek, mert addig nem látom értelmét továbblépni és a tönkremenetel okát keresni. Üdv,Z.
Yamaha AX-530 erősitő
Üdv! Keresem a fenti erősitő rajzát. Amit a kereső talál, az egy sokkal bonyolultabb erősitőé... Köszönöm! Közben megkaptam egy másik fórumon. Feltöltöttem ide is.
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 RX-V630RDS AV RECEIVER Bekapcsolása után 1-2 mp. kikapcsol
Sziasztok. 
A címben említett készülék bekapcsolás után  1-2 mp. kikapcsol. Ezalatt a rövid idő alatt a funkciók működnek(hangerő, bemeneti választó stb.) 
Amennyire tudtam átmértem,végfokozatt,táp jónak tűnik. 
Nem igazán tudom merre kellene tovább keresgélni. 
Ha van valakinek tapasztalata, ötlete kérem ossza meg
köszönöm.
