Avr250. Right speaker half working - Audio Players & Recorders

Disconnect all the cables (except power) and see if it still shuts off. If it does, there is probably internal problem. If not, re-connect speakers one at a time to determine if there's any short

Your (5.1) receiver supports just 6 speakers. Left, Center, Right, Left Surround, Right Surround and Subwoofer.

I have had a look around for this model and from what I could see of it looks mono. Having just a yellow and white front sockets. I think the biggest clue when looking at just images of video recorders is these front sockets. Stereo ones will have two RCA jacks red & white. Mono have just one. You will also see a Yellow jack, but that's for video so ignore that.

switch the speaker connectors and see if the ones that work on the right work on the left. if they do then your amp is ok and the problem is either the wiring for the right side or the right side speakers. If the speakers don't work when you try this swap, then you have a bad channel onn your amp and will need a bench mechanic to fix it, (if you could find one). also make sure that you have a signal to both the right and the left, this can be tested by again doing a swap, take the left feed and put it in the side that is now working and if you hear sound then the inpurs are ok

Hi,

In that case, you most likely have a shorted MOSFET on one of your output channels. The unit is going into protection mode.

This can be caused by shorting your speaker cables or overdriving a speaker.

If you have the skills it is a job that you can do but you would need to find a service manual for the unit and replace the output transistors. You would also need to check some associated circuitry.

A good repair shop should be able to do this for you but you are probably looking at $150+ to do it, maybe more.

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

Holding the harness and looking at it as it would plug into the back of the stereo you have 8 wires in the top half of the harness and 4 in Tue bottom. Working left to right on the top half first is the rear left speaker, front left speaker, front right speaker and rear right speaker. The positive speaker wires are on top the negatives are on bottom.

For the lower half of the harness you have 1 wire in the top row and 3 in the bottom. The one on top is the switched wire to turn the stereo on and off with the ignition. The bottom row from left to right is ground, and 2 constant power wires for stereo memory you can use left right or both to connect to your stereo's memory lead. I hope this helps I was looking to and had to map the wires using some educated guessing and a multi-meter.

I had a same problem.Left speaker with no voice.Fallowing solution worked for me.
Disconnect the sub's electric first.Loosen 4 screws ant pull out the control unit slowly.Be careful, it is tight.Then you will see the big aluminium cooler.Carefully squeeze the two parallel arms between a finger and thumb to bend and get closer them about half mm.Then connect the plugs and play an mp3 to control.If it is ok, replace the control unit and tighten the secrews.

it may be one of the fuses inside

Can you hear anything from it right now, such as scratching noise or something, if you can hear something, then check the audio input cables, or the output to the right speaker, try turning it or something.
If that method didn't works, then possibly there's two conditions:
1. Your right speakers burned, try replacing it with the new ones.
2. Your power board half damaged, the right channel is damaged or something.Maybe the IC's burned or maybe just some minor electronics parts that is not working properly.

this could be a bad connection fault, or a fault with the player. does it work through headphones?
