    The green light is signifying your receiver is going into a "self-protect" mode.

    I have owned 3 of these receivers. They are vicious, pushing 400 watts. They get very hot.

    The problem you're experiencing is the same problem I had. The issue is that your system has detected that you have a FAULTY FAN. The system knows it will over-heat without the fan, so it protects its self.

    Change your fan. Problem solved.

    Good luck finding a fan.

No sound center channel


Check the speaker output settings on the receiver. The receiver may be in a 'stereo' or 'two-channel' mode only.

Tip

Instead of resetting rear speakers each time.....


I have found a similar problem with the rear speakers on this unit (needing to be reset each time the unit was turned off), but found a quicker way around it.....with both the main unit off and the rear receiver off: turn on the rear speaker receiver, then the main unit. If the blue light on the rear receiver does not come on, turn off the main unit, and turn it back on again. This has worked for me ~50 times or so and has worked repeatedly. It's faster than going through the reset phase each time. Also when turning off the system, turn off the main unit first, and then the rear receiver. Sometimes I also simply leave the rear receiver on since it pulls only 4 Watts. Hope this helps any users.....(it also works on my boyfriends older generation model).

A long while back, my RCA RTD218 receiver stopped working. I have since tossed it out. I do however, still have all of the speakers for the system. Is there any possible way to get a replacement receiver...


Troll the auction sites for RTD210 or RTD217 if you want the original electronics. Except as noted below you may get away with using the 6-ohm speakers on any amplifiers that can handle 6-ohm loads.

According to the picture of the speaker hookup on page 5 in the manual they're doing something funky with a wireless transmitter slaved off the subwoofer for driving the rear speakers. That says to me they're sending combining the rear channels with the LFE channel amplifier output.

I have A Techwood 400 watt Home Theater Receiver plr85. When you turn It on About 30 secends after that it mkes a poping noise, and then you cant hear anything .After that the word PROTECT Flashes How can...


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.

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

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.
