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. Here are the "test mode" sections of the service manual. 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 HTR-2866 Internal error-t ír a kijelzőjén
Üdv! Van ez a készülék, bekapcsoláskor a fenti hibaüzenetet írja ki... Mit lehet vele kezdeni? A YouTube-on van fent egy másik modellről ilyen hiba kvázi megoldás, de elég zavaros, hogy mit is csinál, milyen gombokat nyom meg, és amikor csinálja egy jókis rész ki is van takarva a képből... K sok értelme volt így feltenni... De olyasmit vélek felfedezni benne, mintha az a gép elfelejtette volna fiú-e vagy lány, vagyis lefagyott az agya, és újra kéne tanítani, hogy melyik modellhez tartozik az agy, és mit vezéreljen... Tudja-e valamelyikőtök, hogy valójában mi okozza, és mi lehet megoldás? Köszi!
