Sony STR DH130 protection mode
Friends Sony STR DH130 goes into protection mode soon after turning on.  It works for a second then can hear loud pops from speakers.
I've tried the suggested methods to fix but nothing works.  Correct impedance speakers.  Speakers wired correct.  Good ventilation.
I've tested the output transistors in circuit and I don't see anything unusual.  I may pull them to test but will wait for advice here.  I also measure
about 57 volts on the emitter resistors.  Seems high to me.  Anyone?
Sony STR-DE 225 Receiver, sudden interruption of Audio, after switching off everything is ok again
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

 
Sony HCD-RX77 hi-fi nem szabályoz hangerőt!
Kedves tanya lakók! A fent említett hi-fi került hozzám javításra,cd mechanika alapos takarítás után,a szépen viszi a lemezeket és a magnó mechanikát, is újra kellett szíjjaznom.Nos, egy hiba még mindég meg maradt, nem szabályoz egyáltalán a kijelzőn 1-30 ig jelzi is hangerő szintet, de semmit nem hajlandó végre hajtani be kapcsolás után hol max hangerőn szól vagy olyan halkan hogy alig lehet hallani,kontakt hiba nincs,át néztem mindent a végfok modult is mit nézzek még meg valami hasznos tipp??T:Zsolt.
Sony CFD-S03CP MP3 lejátszás gond
Sziasztok! Adott egy Sony CFD-S03CP hordozható lejátszó ami tökéletesen működik ha CD Audio lemez van benne,a gondok akkor kezdődnek mikor MP3 formátumot játszik.Hiba nélkül beolvas majd elkezdi őket játszani de 2-3 másodpercenként ki-ki hagy néhány pillanatra.1,8V LDO-t lecseréltem a BD83S panelon,kondikat is átmértem,feszeket is szkóppal megnéztem és rendben vannak,stabilak.Az olvasófejet is kicseréltem újra,de a hiba maradt...Szívesen fogadnék ötleteket a probléma megoldására nagyobb tapasztalatú fórumtársaktól!Előre is köszönöm!
