Question about Onkyo TX-SR304 Receiver
After about 30 minutes of use, the speakers begin to get very scratchy and fuzzy, and create high pitched noises. Also, the display on the receiver will begin to show garbled random numbers and letters (the volume will increase and decrease, but the digital display will show garbage data). Any advice? Thanks in advance!
This receiver runs VERY hot during normal operation. Make sure you provide good ventilation for it.
With summer here, you might consider a small clip-on fan and clip it near the top of the receiver. The amplifier section is along the front of the chassis - so that's the source of heat.
See if unblocking it helps - then try the fan.
