Szervusztok Erősítős Szakik!
Javítok éppen egy erősítőt(autós erősítő ugyan de azt hiszem a tápegységtől eltekintve nincs különbség az asztalihoz képest). Tápegység hibával került hozzám amit orvosoltam is.A baj az,hogy rendkívül halkan szól.Hídba kötve és csatornánként külön-külön is.Mindenféle szabályozás megvalósul,hangerő hangszín egyaránt,csak rendkívül halkan.
A tápegység 2x37,5V.Végfok tranyók rendben vannak(ohm-osan mérve legalábbis). Valami központi hibára gyanakszom,mivel mindkét csatorna egyaránt rossz,de az elő erősítőben nem találtam hibát(ami nem azt jelenti,hogy nincs is).
Válaszaitokat előre is köszönöm!
Tisztelt Urak!
Tudna-e valaki segíteni, hogy a KSC 2316y és a KSA 916y tranyókat mivel lehetn kiváltani!?
Köszönöm.
Üdv.
Galibali
Sziasztok!.
Nem akartam trollkodni a (Audi concert TT (Blaupunkt) hangerő nem szabályozható. Vadmalacka jóvoltából MEGOLDVA) című topicba
Szó, mint száz: a probléma az, hogy a bizonyos Motorola chip ( XC85556CFN (MC68HC05B32) meghalt.
Olvastam, van egy áthidaló megoldás, Vadmalacka jóvoltából, ez érdekelne engem szájbarágósan.
Ui.: jelenleg nem tudok PIC-et programozni, tehát csak kész "termék" érdekelne, ár megjelöléssel.
üdv Tamás
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
