Since the problem appeared to correct itself on occassion, I would first look for poor solder connections either at the output transistors or at the voltage regulators. Let me know if you need more detail.

SOURCE: Receiver keeps flashing "PROTECT"

The protect message indicates that a problem was detected in the last stage of the amplifier and that it has shutdown to prevent further damage. Usually this indicates that the output transistors have failed. Any shop that works on audio should be able to repair this. Expect a part cost in the $20-$40 range. Add in the local labor rate for the total repair cost.

SOURCE: how to remove the protect signal

Make sure that your input level are not too high. They will cause the an overload in the receiver and it will clip the circuit. This will continue until you lower the level of the input that you have on at that time.


IF THIS HELPS PLEASE VOTE.....GOOD LUCK AND THANKS..

Why does my Teac ag h500 keep saying protect?


Hi. Unfortunately the protection circuit is saving your speakers from a fault, most likely one side of the amplifier in the unit is defective.

This needs an engineer.

I have a TEAC AG L 800 and when i press the ON comand the dysplay shows the word "PROTECT" and then shuts off. What should i do to fix this problem?


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.

Check for loose speaker connections at the speaker as a root cause for intermittent shutdown.

Keeps kicking off saying protect


Hi rifrandle
To answer your question;
Your amplifier goes into protect mode when it detects a fault or condition that could damage the speakers and/or the output stage.

Often caused by shorted outputs.

Although this does`nt tell you much on how to fix this problem, the best help i can give you at this point is to tell you to have it looked at by a repair shop.

Hope this help good luck

It just clicks at the relay but wont turn on


hi this is a common problem on this model .. the standby supply is working D611 gives -5V D612 gives -30V D613 gives f+ supply and D610 gives 5.6v micro supply .if an of these are low change in the live side of psu C627 100uF 35V also change C628 1uF 50V .ALSO CHECK R611 is 47 ohms and also R610 is 1Mohm 1/4watt resistors.. if al this is well . the main psu is not starting this is generally caused by R629 220K 2W or R613 47 OHM 2W being open circuit these are the start up supply feed resistors Also check D628 1N4937 for being S/C .if all thses are OK change C626 1uF 50V and also C625 220uF 35V .these items will generally get the unit to work..if you need any more help email yam_man_dan@yahoo.com
