Re: Power problem - total power failure
You need to make sure that power supply has fried. It requires to check output voltage by volt meter. What is the exact model number of your Sony home theater system to guide you properly. Is it DAV-S500 or some thing else.

Could be just bad luck! It seems unlikely to me that the power supply would take nearly a year to destroy the T-con board!
You could get in touch with Toshiba to see if there is some kind of problem that is cropping up on this model that might cause failure in on the T-con.
Fastest way to check this is to disconnect all speaker wires from the unit leaving the video hooked up and play a disc. If it keeps playing fine, you have a speaker or wire problem. If it still reacts the same, it's an internal problem and would need to be serviced. If the unit continues to play, post a reply and I will describe in detail how to troubleshoot the system. Hope this helps
