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.

Pioneer VSX-321 erősítő HDMI fogadó része nem működik
Sziasztok!

Van nálam egy Pioneer VSX-321 5.1 erősítő. A HDMI nem működik, a forrás nem detektálja az eszközt, nincs hang.
Optikai bemenet működik, szól az erősítő.
Egy 3.3V-os stabilizátor, ami a kontrollert hajtotta csak 2V körül adott ki, ezt cseréltem, most 3.3V (IC207 NJM2831F33). A többi táp is jónak tűnik.
A kontroller I2C lábain 0V-ot mérek, kommunikációt nem látok. Ugyanígy gyanús, hogy a HDMI csatinál is 0V-ot látok az edid lábakon. Felhúzó táp megvan mindkét esetben.

Itt elakadtam.
Van esetleg valakinek tippje, hogyan tovább?

Köszi!
