Check the speakers for shorts or grounds. if all checks out fine try disconnecting power to the deck for a few seconds and then reconnecting it.

I have a Tevion AVR/2006. Soon as you turn it on, it comes up overload protect. Nothing works. Tried resetting nothing works. We have gone all through the manual & can not find anything in the...


The overload protect has activated because the audio output ic has shorted, as a thought! check all speaker connections to make sure wire has not crossed causing issues. I suggest a professional to further inspect your system.

Protect error


Hi,

If your amplifier goes into the protection, there's really something wrong. There are different kind of protections but usually that circuit does see a DC voltage on your speakeroutput.
So it's a protection for your speakers.

Protection light won't stop blinking/ Subs don't work


The amp probably has shorted output transistors to eliminate other possible causes, read through the following page. Let me know if you have any other questions.

Protect


The protect message indicates that a problem was found in the output stage of the amplifier. Unless this gets repaired, nothing will work. As a verification that the speakers or the wires are not the problem, unplug all of the speakers and try again. If protect still is displayed, the problem is inside the unit.

The tape is write protected, remove the tape and make sure the green strip is set to REC as opposed to SAVE.
