Re: Protect

You may have shorted the speaker wires. Remove all wires from the output connections and make doubly sure no strands are left there. Turn volume to zero and turn the receiver on. If the problem persists, you probably fried the output stage. Have it repaired.

I have this issue, my teac ag d7900 which itself off to standby and when I switch it "on" again, it says protect and shut itself down again

Right. This means that either you have a short in your speaker cable somewhere or the short-detector circuitry inside has problems. Disconnect all speaker cables and turn the receiver on. If the symptom goes away, turn the receiver off again and connect one of the speaker wires. Repeat until it starts to go into protect again. When it does, the last speaker you hooked up has a short somewhere in the wire.
If protect always comes on, you'll need to get the unit serviced.

Teac AG V7700 Receiver problem powering up

I have a Teac ag-7700 and when I would try to power it on it would shut off. I did get it to turn on for about 10 minutes and then it shut off. Now when I try to power it on the light on volume dial stays lit but the LED does not light up and no sound through speakers.

Have a teac amp and dvd / cd player moved house plugged in and now amp makes clicking noise and displays "protect" ?? tried resetting as per manufacturers instructions ............still no joy ?

Protect mode happens when the amp detects a problem internally and shuts down to prevent further damage. The most common cause of this is shorted output transistors. Without takeing measuremetns inside the unit, I can not state the specific problem, but a repair for this is relatively simple. Expect a cost of $15-$40 for parts plus the local labor rate.

Protect keeps flashing

there is a similar problem to yours on here. also, does it take a minute to go into protect or does it happen almost immediately? i'd unplug all your speakers from the back of the receiver and turn it on, if it still goes into protect it sounds like an internal problem which has been addressed. look at this for internal problems;
