Onkyo TX-NR414 erősítő, nem lehet bekapcsolni
Van egy Onkyo erősítő, melynek hibája, hogy nem lehet bekapcsolni. A készenléti panelra rámértem biztosíték jó, a kimenetén a 12vés a 9v megjelenik. Ez a tápfesz rácsatlakozik a HDMI panelra. Szerintem ezen a panelon kellene a hibát keresni, innen jön vissza az a kapcsoló jel, amelyik a készenléti relét kapcsolná a rajz szerint. Kérnék egy kis segítséget a hiba feltárásához.
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?
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.
