Hozzám került egy Onkyo TX-SR500 erősítő, nem jön ki belőle hang. Bekapcsol, kezelőfunkciók működnek, de hangot sehogy nem ad. Oszciloszkóp nélkül nehéz...Tápok szerintem megvannak mindenütt. Valaki nem találkozott ilyen hibával? Gyanakszom a bemenet választó IC-re.
Sziasztok.
Egy Sony MDX 100 RDS tip. autórádió végfok IC hibás de sehol nem találok róla infót.
Az IC tip.: Sony 160-00-4D4. Nekem nem úgy tünik hogy ez lenne a tipusa, de más nincs.
Ha valaki már találkozott ilyennel köszönöm ha tudna segiteni.
I Have a Sony STR-V55 stereo receiver and need a relay for it. It is 24 volt and the Soney part number is 1-515-347-00. RY801 on the schematic. Can anyone give me an idea how to cross reference the Sony part number? I am not having much luck finding it on line.
Thanks
Sziasztok!
Hozzám került a cimben szereplö szörnyeteg!
Nem gyári állapotu, mert a toroid helyett hiperszil van benne amelynek emelt a tápfesze 42 volt.
Müsorforrás nélkül kb 5 perc mulva langyos a jobb oldali végfok hütöbordája.
Viszont müsorforrással szépen torzitásmentesen szol.
Esetleg a nyugalmi árama lehet rossz?
Emelt tápfesz nem okoz gondot?
Letekert hangerönél semmi rendellenes zaj,illetve müsorforrás nélkül teljes hangerön sincs zaj.
Valaki elkezdte modifikálni, de teljesen pozitiv irányba.
üdv:atis
