I have a Sony SA-WM40 subwoofer that has seen approximately 3 years of heavy use. As many people know, its a great sub after the polyfill and mod-podge mods. However, the problem I recently started noticing is that after playing a CD for a few songs, it spontaneously cuts off during the middle of a song for anywhere between 5 to 10 minutes and then comes back on randomly. It then proceeds to switch on and off at random intervals. Its like it has a mind of its own. What is weird is the power light stays on and stays green throughout. I do hear a "click" like as if it were shutting off or switching or something when this happens though.

Has anyone else encounteed this problem with this sub? I thought it might be the "power save auto turn on/off" function that is built in, so I switched it to manual but the same thing happened anyway. I figure the cheap, built in amp is just plain wore out and old. Is it time to get a new sub, or is there an easy cheap fix for this?
