Sziasztok!
Tippet, segítséget kérnék 3 tálcás Philips 680C midi HiFi hibájának behatárolásához, tapasztalat hiány miatt.
A forgótálca mechanikájában a szíjakat már lecseréltem.
Philips VAM1021 optika
Hiba:
Mindhárom lemezt pozícióba forgatja, a motor a lemezt egy fél körben megmozdítja, majd leáll.
Az optika is 2-3 alkalommal felemelkedik, de fényt nem látok a lencsén üres tálcánál.
Mindhárom lemeznél megismétli, majd NO DISK felirat a kijelzőn.
Köszönöm a válaszokat, üdv: Csaba

Üdv!
Ismeri valaki a tárgybeli mütyűrt? Az URH lassan elhangolódik, de még fél óra után sem áll be, kúszik-mászik-bosszant, és nem jutok a végére, a kapcsolása meg nagyon cikornyás...
Üdv. mindenkinek!
Jelenség az alábbi: 88 Mhz-től felfelé haladva az adók egyre gyengébben foghatóak. A kábel TV-én a rádió csatornák beosztása 1Mhz léptékben van, és 100 megán már alig halható a müsor ( Petőfi ).
A kapcsrajzot nem találtam meg, igy az LA1823 adatlapja alapján próbáltam eligazodni. Hangoló fesz rendben, AGC van, frekvencia kijelzés OK, állomás keresés közben a némitás OK.
Kérem ha valakinek van rajza vagy ötlete, hogy mi okozhatja e hibát segitsen.
Tisztelettel, welding alt
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.
