When you press the standby button to turn the system on it comes up with 'PROTECT' and then says 'SEE YOU' and switches itself off - how can I get rid of this?

sometimes the system can get a little "rusty" after inactivity. The most common simple solution is to unplug it then plug it back in

The receiver is in protect mode, most likely due to a damaged amplifier. This protect mode, keeps the unit from turning on and causing further damage to itself and/or your speaker system. For more information, please visit my website at audioserviceclinic.com. Thank you.

Check its mechanism for fault.

Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

If protect is coming up on the display, it means the system is detecting a short somewhere on one of the speakers and so is turning the amp off to avoid damage.
Check all the connections at the back of the amp to ensure they are not shorting, and at the back of each speaker, if nothing is found there, check each wire for damage, or a bare wire touching the body of the car

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 Amps metal case. Check that first.
It can also be caused by unstable ohm loads if too many speakers 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.

unit seems to go into protect mode.Theres very little that can be done..There is good chance unit needs to be checked at a repair shop.Try to find one that is authorized for your particular brand if possible

This a memory problem ,try to look for the reset button and press it . If you can't find the reset button then the other option is unplug the unit for 24 hours the purpose is to reset and dessipate or drain the charged current .

Hope it may help you;

I managed to find a local repair man who fixed the problem. He put in a new transformer.

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