Onkyo speciális alkatrészeket honnan
Sziasztok! Remélem nem nagyon egyértelmű a kérdés amit felteszek :) Onkyo TX-840-hez kéne nekem egy motoros hangerőpoti. Alps gyártmány, de a HQnál ötletük sincs hol kéne keresnem. Az egyik oldala száz százalékos halott. Hasonló motor nélküli is megtenné, mert úgysincs meg a távja :) Ötleteket örömmel várok laci fotót holnap prezentálok. jelenleg egy "márkakereskedés-féle" is megtenné. ahol jártam: HQ, Lomex, Sini
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-DS797
Kedves kollégák! Tanulságos hiba megoldását szeretném közzétenni, ha valaki találkozik eme jelenséggel, / könnyen lehet, hogy típushiba/ egyszerűbb lehet a megoldás. A hibajelenség: Minden működött a gépen csak éppen egy hang nem jött ki a kimeneten. Táp, végfok minden jó volt, a hűtő ventilátor nem ment. Gyanús volt, hogy valami tiltás az oka a jelenségnek. A Main circuit PC board nevű, "U1" jelű panelen található memória kapacitás nyák felőli oldalán egy pici rozsdafolt jelezte, hogy kilyukadt. A kigőzölgő elektrolit a lyukgalvanizálást szétmarta több ponton. A pontok vezetékkel való pótlása és a kondi csere után a hiba elhárult. Laszlo 61 :D
