I have a Pioneer RX-590 4 Channel stereo in my room that my dad gave to me as a moving-out gift. and whenever I listen to the radio on it or plug my xbox into it, it works fine at first for a few minutes,but then the speakers just turn off for about 3 seconds and then turn back on. the display still shows that it is playing the music but it has been doing this ever since I hooked it up in my new room. I just bought new 16-gauge wire for all 5 speakers. It doesn't matter what the volume is on it either. the speakers still go on and off. sometimes it does it 4 or 5 times in a minute. I'm getting worried that it might be damaging the system so i stopped using it completely. I believe it was manufactured in 1997 but it worked fantastically until now. please help me figure this out
