my reciever has a problem with the mian front channels (l+r). I just hear crackling and static. The other channels are all ok. This started as an intermitant problem but now it seems permanent. Is there a relay(s) that connect these channels whos contacts have gotten worn out?
please advise or provide schematic / part no. If possible.

if front left is working it is possible u have a dry solder on ur right channel line. try resoldering or if u want to know exactly where dry solder is, shake gently every right channel components and connections. if resoldering does not work it is possible u have a faulty ouput amp for ur right channel. if ur not sure about this i suggest u get it checked by a qualified tech.
Try connecting one of your other speakers to the centre channel on the amp to see if it is the speaker or the Reciever. If the speaker does not crackle then chances are the centre speaker is probably blown and will require replacing.
A possible cause for the static in your cordless phones could be dimmer switches around the area of your phone that causes static. Turn the switches completely off (not just turned down) and see if the static leaves. You can replace the dimmers with regular switches if that clears your static. If it does not, another trace for interference: you will have to take a portable radio and turn it to AM 550 mHz and tune it to the loudest crackling noise. Carry the radio around looking for the loudest static interference. Could be a loose connection in a receptacle or panel box. Any small malfunction can cause static on wireless devices.
Hello, There is not compability issue, sounds like you have a mic problem because you hear the Roger Beep and that means that the transmition and Reception cicle is working if you could test an audio accesorie would be great.
There is another possibility if one of the radios is out of frequency you could experiment the same symtoms.
there is no chance that you can fix this problem by replacing speaker wires. Resoldering the output stages as well as area around the microprocesor could be the efficient solution.
If you need more info please advice.
