Question about Panasonic SA-HE75 Receiver
When turning the volume up, it goes from minus 85 to zero.
Without any sound, off course.
Any suggestion ?
It's usually happen when the unit is overheating the malfunction on the device is always there. The parts inside or the what we call the resistor / transistor / IC / are the one affected when the unit get warm, the parts can be cook for that instant heat and no exhaust of the hot air inside to put outside..
Only one parts have cook or melted or got the problem due to device overheating, you probably got the best of both world that your device will malfunction and soon be a dead set one.
