I would say to check your manual, and if not, get it repaired (if you can). If you need to use a last resort, then just replace your dvd player with a new one.

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.

ONLY TURN STANDBY


Hi.

The standby is forced because a fault had been detected.
The TV is in protect mode, because a fault had been detected.

If the TV went in standby and does not wake up, then the TV is in protect mode.

In protect mode higher voltages from PSU gets shut down and TV remains in standby.(see also Why my TV does not start up and remains in...)

Try first leaving the TVpower cord unplugged for some times, let say one hour or so. Then connect powr

If that does not work, and you keep having the TV in protect mode, it means that there is a fault.

In that case call the phone support number listed on the user manual to arrange repair.

Is the red light flashing at first?
The unit may be going into protect mode. Lets hope it has done the job and the receiver has protected itself from failure.
Protect mode can result from speaker wires touching each other or the Amps2_bing.gif metal case. Check that first.
It can also be caused by unstable ohm loads if too many speakers2_bing.gif are connected to any of the outputs especially zone 2.
If you can remove all speaker wires and turn the unit back on. If it stays on, turn the volume down on the main zone and zone 2 if connected. Then reconnect speaker wires.

The receiver has gone into a protect mode because something is wrong and it shuts down to prevent further damage. Could be a power supply or output amp issue.

Stuck on standby


Unit is in protect mode there are a few problems that can trigger protect mode the most common is blown channel (shorted outputs). Sometimes one of the 15v regulators may go bad causing imbalance of supplys triggering protect mode. Also sometimes a bad solder connection could cause unit to go into protect also.

Going into protect due to either blown channel or probably a 15v regulator might be down which I have seen many times also. causing unit to go into protect.

Denon surround saying protect on display


Make sure none of your speaker wires are touching, this will cause it to shut down instantly.

Flashing PROTECT


This is often caused by a problem with the speakers or speaker wiring. A speaker wire that's pinched behind the head unit will cause this problem if it's shorted to dash metal or the deck chassis. The first thing to do is remove the head unit and inspect all the speaker wiring for bare spots or pinched spots. If everything looks okay, disconnect all four speakers from the deck and switch it on. If it still shows "protect" then you have a defective head unit. If not, then turn it off, re-connect one of the speakers, and turn it on again. Continue until you find the speaker output that puts the deck into protect mode.
