Üdv Mesterek!Keresném a JVC KD-G 631 autórádió rajzát. Előre köszönve. Öreg T
Üdv mindenkinek.
Van egy 2.1 hangfalszettem és néha pattogó hangot ad ki főleg akkor ha pl: lekapcsolom  a villanyt de van olyankor hogy búg de elég hangosan.
A hangfalszett a számítógép hangkártyába van dugva jack dugóval forrasztva a vezetékek gondosan elszigetelve egymástól.A számítógép  egy szünetmentesről kap áramot a szünetmentes pedig egy túlfeszültségvédő elosztóba van dugva.
Mitől van ez a jelenség?
A gép külön áramkörről kap áramot.
Valami zavarszűrő kellene ami megszűrné a hálózat okozta zajokat?
Válaszotokat köszönöm.
Üdv:Gábor
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?
Sziasztok/Hello Everyone!
Accuphse P-400-hoz keresek service manual-t, vagy egy jól kivehető kapcsolási rajzot. Amennyiben valakinek van ilyen azt nagyon szépen megköszönöm!
I'm looking for a service manual for the legendary Accuphase P-400 or at least a good resolution readable schamatic. I'd be really greatful if someone could share one!
Köszömöm!
"Rajzot, service manualt, jobbra a "Keresem/WANTED" doboz "KATT IDE" gombján keresztül kérj!"
