I have a RCA RT2500. Has been working fine since purchased new. Turned on today, and it immediately turned off. There was a message that flashed - CK SPKR. I tried to restore factory settings, checked speaker wires, checked all component connections, all were fine. Any suggestions? The RCA and Thomson web sites were of no help. Thanks.
I have also the same problem, I am area of Montreal, we had a power failure and I think that we had a electic overload
