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 RXV-420RDS távirányító hol megy, hol nem
Üdv Mindenki! A fenti készülék távirányítója hol megy, hol nem. A távadó IC típusa JT-7062-2. Az IC körül minden alkatrész átnézve, Infra LED ellenőrizve, a tápot az IC megkapja. A panel erős nagyítás alatt is és a szakadásvizsgálóval is mérve hibátlannak tűnik. Van rajta egy 3,64MHz-es 3 lábú rezonátor, aminek működését oszcilloszkóp hiányában sajnos nem tudom ellenőrizni, pedig én arra nyanakszom, mert gyakran koppant a padlón. Szerintetek mi más lehet még? Az alábbi távok jók elvileg hozzá: - RAV14 V694130 - RAV205 V4732200 - RAV206 V6940901 és V6940900 Köszi
YAMAHA TX-1000 tunerhez antenna csatlakozó dugó kellene
Sziasztok! A tuner hátoldalán 9,4 mm külső átmérőjű, a normál antenna dugó méretével pontosan megegyező, viszont nem dugó, hanem aljzat van. A középső részén 1 mm átmérőjű érintkezőt tud befogadni. Én ilyen csatlakozó aljzattal eddig még nem találkoztam, de nemrég egy ismerős már keresett nálam ilyet, de csak fényképet mutatott róla. Valakinek ismerős ez a csatlakozó aljzat? Normál antenna dugókkal nem lehet összecsatlakoztatni, kiszerelni sem szeretném, hiszen ez egy aranyozott minőségi csatlakozó aljzat. Mellékelem a fényképet.
