ONKYO amplifier dolby surround, Problem with a Switching Diode
Hi everyone

Could somebody tell me if I can replace a switching diode to another one, the one installed in the onkyo is a 1SS252 and is 10 times more expensive that a 1SS355.

Usually I order the same but they are pricey (around 10.00 usd for a 100) and not commonly used, not many sellers.
For the 1ss355 every seller on line has it in stock and it's around 1 to 2 usd for a 100.
Ans they are available locally, not in china waiting 5 weeks for the part.
Thank you.

Onkyo TX-NR646 NG:LCRSLSRBLBR hiba javítása
Van egy Onkyo TX-NR646 házimozi. Bekapcsolás után ezt az üzenetet írja ki. NG:LCRSLSRBLBR. A reset nem segít. A végtranzisztorok mérve jók, feszültségek megvannak.
Van valakinek ötlete, hogyan tovább?

Előre is köszönöm.

Mindenkinek Boldog Újévet Kívánok!
Onkyo TX7830-nel a hangerogomb forgatasara a hangszorok membranjai ki/be mozdulnak.
Sziasztok. Van ez az Onkyo Tx7830 radios erositom. Mukodik rendesen, de ha a hangerogombot (jel nelkul) gyorsan forgatom fel vagy le, a melyhangszorok membranjai kifele ill. befele mozdulnak. He elegge gyorsan forgatom, a vedelem le is tilt. Lassu forgatasnal ez a jelenseg nem jon elo. Van a Tanyan s.m. rola, nezegettem is, de nem latom a kapcsolatot a hangero novelese v. csokkentese es a membranok mozgasa kozt. A hangeropotmeter es a meghajto ic. bemenete kozott van egy muveleti erosito, es ez galvanikusan le van valasztva ugy a potmeterrol, mint a meghajto ic-rol.  Ha valakinek lenne valami konstruktiv otlete, ne tartsa magaban. Koszonom.

Sziasztok! A segítségeteket szeretném kérni a fent nevezett erősítővel kapcsolatban. Minden működik rajta, de nem jön ki belőle semmi hang. Az egyik ismerősöm hozta, hogy nézzem meg neki, ugyanis a felesége mindig letakarja a szellőző nyílását a tetején egy terítővel mondván biztosan leégett a végfoka. A végfokait megmértem mind jó. Mi lehet a baja? És nem igazán akar működni rajta a hangerő gomb sem (sokszori körbetekerés után 1-et változik) a távirányítóval tökéletesen működik.
