SOURCE: my techwood plr85 keeps saying PROTECT every time i turn it on.

disconnect the speakers one at a time and see if the protect goes off.there may be shorted speaker leads on the back of the amp or a speaker.a common thing is to hit the wires with a vacuum or furniture.once i saw someone hang a picture and put a nail right thru one of the wires that were installed when the home was built.if all speakers are disconnected and the protect is still on,then there is a dc fault in the amp and it needs to be looked at.the most common cause is a blown output transistor or ic

SOURCE: I have A Techwood 400

Generally speaking, an amp protects itself from heat, shorts and overloads.


Overloads can be from excessive periods of high output 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 hands-on tech.

I have a Techwood reciever. I need to replace the motor for the fan. Please tell me where I can order this part! Thanks a bunch! Diana


I believe that Techwood is no longer in business. You could try electronics site such as mcm electronics or encompass electronics for a fan.

My (Techwood 400 Watt Home Theater Receiver PLR85) won't turn on


I have had the same problem.

You have a faulty cooling fan.

The system senses the fan isn't working, and knows that without it, it will over-heat. So it goes into a "self-protect" mode - hence the green light.

You need to replace whatever part of your fan has gone bad.

Fuse # 7 (Fan)


4cyl or 6cyl engine? Have the cooling fan switch checked. It is supposed to go on when certain temp is reached, but it apparently isn't functioning properly if it isn't turning the fan off when the temp drops.
