Yamaha rx-v477 házimozi erősítő, processzor nem indul
Kedves Kollégák!

A címben szereplő erősítő TMPM362F10FG processzora nem működik, 3,3V os tápfeszültsége rendben van de sajnos hidegen 8ohm al terheli valami.
Nem kezdtem még keresgélni a terhelés forrását mivel elég kicsik a forrasztások, de nagy valószínüséggel a processzor okozhatja. 
Kérdésem, hogy lehet-e üres processzorral cerélni? Pl: aliexpressről.

Üdv: S. István
