It could be a dirty control or switch, working them back and forth could prove that. Other than that, It's likely bad outputs. A unit that old may have transistors for outputs but might be IC's. Transistors can be tested with an ohm meter to see if they're good or not. Also if it has transistor outputs, they may have a small value resistor on the Emitters, check those as well.
Hope that helps...

SOURCE: Pioneer sx-205 gives a overload
Does it play normal on any sources, or do you only have the tuner and CD for available sources?
There are many different things that can cause this type of problem.
It could be bad solder connections on in the amplifier circuit or power supply, it could be a bad speaker or a bad output channel inside the receiver if this happens only when it gets turned up loud.
The overload warning happens when the amplifier circuit has excessive current or DC voltage on the outputs. Unfortunately the only way to determain if it is the speakers is to change them with other known good speakers and see if it still happens. But before buying any speakers you need to have the receiver ruled out as the source of the problem.
It can also go into overload if you have the wrong type of speakers connected, or too many speakers connected. Each speaker jack should only have one speaker connected toit. If you are using for example, 4 speakers connected to the "A" speaker jacks meant for just 2 speakers, it will create a load to the amplifier that the amplifier is not rated for.
Look on the back of the receiver and it will have listed the proper impeadance for your receiver. Most will say:
8 ohms or more "A" or "B" speakers
16 ohms "A" and "B" speakers
That means you must use 8 ohm or higher ohm rated speakers if you are using only speakers"A" or only speakers "B", but can not use 8 ohm speakers if you are using speakers "A" and "B" at the same time. Then they must be 16 ohm speakers.
Two 8 ohm speakers in one speaker jack is a 4 ohm load, that is why you can not use more than 1 speaker per speaker jack.
I hope you found this information useful, and if I can be more help just let me know.

Just to be sure we are talking the same unit I have included the link to the user manual for SX-255R
1. have you tried to press the Muting button on the remote unit.
(item 11 remote unit diagram)? does it make any diffrence - what if the button is stuck?
2. Have you tried to play the Tuner radio - what happens then? do you still get Muting.
3. You mentioned something about speaker wire coming out.
I understand that Pioneer receivers shut off if any of the speakers is faulty, ie, correct impedance is not showing at the speaker input point.
Usually the newer units give an "overload" message. It is possible this could be happening and the SX-255R gives the "muting" message instead. Some people have reported very minute shorts where strands of the speaker wire touch the body and it causes "overload".
One way to check is to remove speakers wires one by one and see if the "muting" goes away. Then you can check the offending speaker if that is what is happening.
Please do drop a comment to say how you progressed.
