Reset "PROTECT" on Onkyo TX-SV434 receiver?
The left speaker wires on my Onkyo TX-SV434 receiver were shorted out
while the unit was under power (don't ask, it involves kids). There was a spark at the wire terminus and the receiver went dead (sound-wise). The display said "PROTECT" which I know is the protect mode for Onkyo. I searched around on the Net for reset info, but nothing was immediately apparent. Two tactics that I found on the Net and tried we On my Onkyo, turn the unit on, push and hold Video-1, then push Speaker A. It will respond with 'CLEAR'. Mine is still stuck in Protect mode, but maybe this will help someone. HOLD IN THE VIDEO-1 BUTTON WHILE POWERING UP... However, neither of these worked. I did get the "CLEAR" reading, but the unit powered down immediately. I opened up the unit, but the fuse is apparently intact (could it still be burned out, though?), and there are no obvious "switches". So, what do you think? Should I just get ready to send the unit to the shop? Thank you for your help, Tom |

If it's not worth spending up to around 150.00 or so, maybe time for a new receiver. Mark Z. (Authorized Onkyo serviver - Wichita, Ks.) |

It sounds like you burned out the Protect circuitry. Time for a visit to
repair it. -- DaveW ---------------- "Serial # 19781010" wrote in message ...

Reset "PROTECT" on Onkyo TX-SV434 receiver?
How does one 'burn out the protect circuitry' by shorting speaker wires?
The protection circuit is doing exactly what it's supposed to do, protect the speaker(s) from damage in the event of an amplifier failure. One amp channel (at least) is damaged. Mark Z.
