Hi, I have a Pioneer vsx 922 Home AV amp. Its has worked great, till the other day when the speech on a film was not...

Mine is doing nearly the same thing. Turns off in the same way, no light or warning, just off. But mine can go for hours...

Hi, I have nearly the same issue. Turns off after hours or them mins, but never reason for time. No lights show, remove lead from back and push it back in and it turns on again. Had the PSU replaced, and formatted harddrive but still the same. So you think it could be a faulty HD, and replacing this will finally sort it?
