Re: Onkyo TX-SV434 "Protect" light
The protect mode is a built in safety message, indicating that theres a fault somewhere with-in the unit, and it wont let the unit come on fully or more damage will occour. This unit is a solid state device, and you should not attempt to use it or open it or try any self repair as it will cause more damage. If this unit is more then a few years old , it might just be the time to start looking around at all the back to school sales on electronics, as to have this unit serviced will cost an estimate fee as well as parts and labor. If you want to invest a few bucks into this machince , then go for it, but its most likly will cost 1/2 or more then the cost of the entire unit did when it was new to have it repaired. It is up to you. Good Luck

hello the output transistor could have blown. this can happen if you play your receiver with high volume all the time the transistor heats up causing it to blow there are other components you can check first like any glass type fuses see if any have blown if ok check the capacitor see if any have swelled up or poped hope it helps
Does the display show "tuned" or "FM Stereo"? This would normally indicate a good reception. The tuner has a signal level threshold and if the signal gets to week, the receiver mutes to prevent noise in the speakers. Swithing to mono make reception less intolerant. Does the problem also occur, when you switch to mono?
There is a problem with one or both of the audio amp circuits. The amp is going into a protect mode as to protect and save your speakers. Sorry but there is no simple fix. this will need to go to the shop to be diagnoised. Good Luck
the system protect is usually displayed when a condition of short or shorting is occurring in the speaker wiring or the voice coil of any of your speakers.... thte circuit of you reciever is trying to protect itself and you from a very costly repair,,,so it you have another set of speakers try to use them and see if the condition still exists and if it does the problem is in the output section of the receiver,,,and if the protect no longer exists you have fixed your problem,,,good luck
