Audio output shorted out or blown fuses in power supply check all fuses if fuses are good your Audio out put transitors or I.C has been shorted out as a result of impedence over load in future dont connect speakers in parallel in those small Audio units.
I had the same problem. I can't fix it, and neither could RCA customer service. The only way I could think of was to find a surge protector extension cord that had a on/off switch to make it easier to turn on. Another solution might be to buy a cheap wall timer, the kind you use to turn lights on/off. That resets it every day and it should be OK.
No, I doubt if the surge device is causing your problem. most likely there is a power supply issue, or a fauly with one of the servo or motor driver circuits. This is not a repair or a quickie fix for the end user I'm afraid. This unit is going to need to be taken into a repair shop to be diagnoised. Good Luck
Its not a typical repair that a do it yourselfer can do unless youve had troubleshooting experience on microprocessors. Your problem could be the 5 volt power supply is not filtered clean when it warms up or the reset voltage falls too low for the micro. good luck
