Hello, I got a problem with my Sony Receiver STR-DE 225.
There´s a sudden interruption of Audio in non defined intervalls - may be once ore 6 times during appr. 5hrs operation.
Interruption does not depend on Volume. Connection cables and speakers I´ve checked.
There´s a loud crack in both speakers, display shows for short time "PROTECTION".
After switching off and on again, everything operates normal until next interruption.
I removed from the inside of the receiver a lot of dust with a vacuum cleaner, but this didn´t help.
Unfortunately Sony has no documents for this device, as it is To "old" (1996), or could give me a hint,
in what cases "PROTECTION" might appear.
Is there anyone to give me a clue? Thanks

Sziasztok!
Most épp egy UNITRA MDS411D-t restaurálok.
A lista ami eddig megvan:
1. Szíjcserék.
2. Kombifej és törlőfej cserék.
3. A fejhez vezető kábelek.
4. Kontakt hibák megszüntetése.
5. Átkondizás ahol kellett.
Most már tökéletesen szól! Szép hangja van. :)
A PLAY, REC, PAUSE, STOP gombokra rendesen reagál és teszi dolgát.
De a csévélés nem úgy akar működni ahogy kellene.
A led az felvillan ami a gomb felett van, de nem pörgeti a motort.
Ha a REED relénél lévő szíjtárcsát (amin a mágnes is van) egy kicsit megmozdítom,
egyből el kezd csévélni.
DE!!!!!!!
A féket akkor se engedi ki!!!!!
Lejátszásnál kiengedi a féket.
Ha manuálisan "féktelenítem" akkor rendesen csévél.
Előre és hátra.
Ha várok vele 1-2mp-t akkor ismét meg kell "izgatni" a REED-et hogy csévéljen.
A kapcsolási rajza:

Előre is kösz, a szakértelmet.
Mint olvastam a file megnyitási problémákat:
A DJVU file nézegető pedig itt: http://windjview.soft112.com/
Én ezt használom már régóta. Soha nem volt vele problémám. :)
Üdvözletem Mesterek !
Keresem a JVC KD-R 821BT rajzát.
Kicsit leejtették a végfok hűtőbordára.
Nem akar indúlni.
A Tanyán nem találtam.
Előre köszönve és tisztelettel: Öreg T.
A probléma megoldódott .
Megint dolgozhattam egy nagyot , az előlap is kettétört, úgyhogy kuka.
Ha valakinek lenne előlapja felkinálnám a tulajnak.
Üdv :Öreg Tom
Because I did not found it and I was forced to buy, you get it for free!
