Question about Yamaha RX-V3000 Receiver
Recently, I began to experience a high pitch, crackling sound coming from my Polk RM 7500 right channel while watching a dvd, War, at high volume level. The crackling sound will come and go, very annoying. Obviously, something is wrong. The crackling sound appears at higher levels usually when listening in DTS, or any other high quality sound track.
When playing at regular sound track you kind of don't notice the sound distortion but if you get your ear close to the right speaker, channel, you hear a distortion in the sound from both mid and tweeter in that channel. I have check for wire connection and also use the speaker in the right channel to the left and vise versa and noticed that the speaker in the right sounded good in the left channel. However, the speaker that I moved from the right channel to the left sounded crackling, distorted on the right. To me is not the speaker but??? What could the problem be?
As I was typing this, I was listening at regular sound level without the high distorted, crackling sound and all of the sudden from the right channel distortion started at an annoying level.

yep but if your not a tech you should take this easy repair to a pro. Your problem is an open emitter resitor and happens when the units over driven or a speaker is bad for a while while it was working. if your a tech then check all of the emmitter resistors. also it could be a bad output device. Good Luck

Yes, sounds like your DSP chip has an issue. Not an inexpensive repair if that's the culpret. Around 400-500 to replace the chip. It's an awesome receiver and worth 300-400 in repair, however, a 3800 or 1800 can be had for 600-800 depending where you look. If you need more help, post a comment and I can help you some more.

SOURCE: No sound from left channel
It's possible you've blown the left channel, but the fact that you have no audio in the left channel from both A and B speakers makes me wonder whether the balance control has been accidentally rotated to the right.
There is a rotary control on the front of the receiver for BALANCE. This should be in the 0 position, i.e. top dead centre. If it's been moved to the right, you wont get audio from the left channel from either A or B speakers.
Please check your balance control first then let me know if you need further assistance. You can reply to me by clicking on "Add a Comment" below your question.
