My PRX715 stops working after a few minutes of play. The LED in the front goes from blue to red; obviously no volume from the speakers when the light goes red but it works/sounds fine while the light is blue.
The fan works while the speaker sends out volume but stops when the light goes red.
I have tried both inputs and different cables.
It may be power safe mode.
When input signal level too low it switch to this mode.
Try compromise with sending line signal from desk and gain level on the speaker to enough loud signal
damage is on the input usually ic 33078
I can't explain exactly. because it can be different.
you can also ask for help at your local service center.
hope it helps
