I have a Pioneer Elite VSX-49 (just 49, not TX or TXi) which I have had for several years. All of a sudden I started getting a cracking out of a single channel. Here are the symptoms ...
1. The cracking is only one in one channel
2. The cracking is independent of any control on the front panel & input source
3. The crackling occurs even when the volume is turned all the way down
4. The crackling usually is delayed from turning on the amplifier. It takes anywhere from 2 to 10 minutes before the crackling starts.
I have tried pressing on the circuit board with the rubber end of a pencil to try and tease out a correlation (thinking that a bad solder joint may be the problem) but to no avail.
Does anyone have any idea of what it may be and/or some tests which could prove insightful?
