Most vettem a neten, de FM-ben csak a Juventus szól gyatrán.Tudnátok segíteni mivel kezdjem? (Egyenlőre se rajz se manual nincs hozzá)
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

Hello, I am in a repair KENWOOD KRF-X9995D.
Let me know if anyone is aware of how to reset the processor.
That is about a year ago I had the same problem with another amp of the same model!
So this is the second unit can not repair!
The main flaw is that the accumulation of around 1F 5.5V had spilled acid. was also in the same thing happened! ie it shows mute, but going into test mode, (having pressed the key "INPUT SELECTOR DOWN" and "POWER", the analog input works (but only in TEST).
Any help?
Thank you
Sziasztok.
A címben említett MINI HiFi van nálam nagy generálon.
A mai nap elkészültem mindennel! :)
De a kijelző az nagyon zavaró....
Elég halvány.
Összességében 2db alkatrész tartozik a fűtéshez amit találtam a rajzon.
ZD302 6,8v Zener
C304 47uf 50v Elko
Ezt a 2 alkatrész kicseréltem, de semmi változás.
+ amúgy 4,5v-ot mértem a cső F1 és F2 lábainál.
Csak azt nem tudom, hogy ez jó érték-e?
Vagy az is lehet, hogy a CSŐ kezdi magát megadni?
Ahogy nézegettem, a tanya bázisában megtalálható a rajza.
Ha valakinek van egyéb más ötlete szívesen fogadom.
