Can anyone help me with this service manual?
I have a unit with damaged Ethernet port.
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,
egy Onkyo minihifi (CR-185) áramtalanítás után mindig lenullázza az óráját, gondoltam kicserélem benne a szuperkondit.
Azonban semmi nem változott, ugyanúgy 0:00 fogad ha kihúzom és visszadugom.
Merre érdemes elindulnom a hibakereséssel?
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.
1SS352
