Onkyo TX-NR509 HDMI panelre befutó jelekre nem reagál.
Egy Onkyo TX-NR509-em van, az a gond vele, hogy az analóg bemeneteken kívül semmit nem érzékel. Van egy panel benne, amire az összes HDMI csatlakozás megy, innen van HDMI kimenet a TV-re. Ide érkezik a NET csatlakozás, és az előlapról usbl pl. IPOD-nak stb. Ezeket a TV kimeneten kivételével nem érzékeli. A SETUP pontokat látom a TV-n, de a fenti digitális bemenetek állítási lehetőségei nem aktívak. Van valakinek ötlete, hol kezdjem? Kapcsolási rajzom van. Előre is köszi!

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 A8630 nem mukodik a bemenetvalasztas
Sziasztok. A cimbeli erositovel szenvedek. Hibasan vettem, csak az egyik bemenetrol mukodott. Mikor levettem a tetejet, lattam, hogy a bementvalaszto ic at van kotve. Rendeltem egy masikat, de ez sem akar mukodni. Mintha teljesen halott lenne, nem megy at a jel rajta - nincs egy bemenet sem kivalasztva. +- tapfeszek megvannak, a kapcsolat a kontrollerrel pin to pin leellenorizve. Nincs tobb otletem, szerintem 2 lehetoseg maradt: vagy a bementvalaszto ic halott, vagy a kontroller, bar a kivalasztott bemenetnek megfelelo ledek kigyulnak. Volt valakinek hasonlo esete?
