SOURCE: E250P Not powering on... chirping noise
I had the same chirping issue with the sub. I found a document that talks about replacing the C5 capacitor for a 47mfd type instead of 470mfd. This solved the chirping issue however I still experience an intermittend issue with the power on indicator flickering off and on. Anyone hear of the fix for this?

Your speaker is an active one. This means that it has indepented amplifier for low and high frequencies. So maybe the woofer (low speaker) is still active but its amplifier is defective. In order to make things more clear take a look at this block diagram to understand the signal flow:
I suggest you to unscrew the screws at the back panel and eject the whole electronics from the inside:
Take care the cables that connect the electronics with the speakers. If it's easy mark what goes where and unplug these cables. Now with the electronics on the table try to locate fuse(s) that may have been blown; since you don't smell burned components, fuses is the most common problem. Replace any blown fuse with the same one and put things back in the proper order. In case that you don't locate any fuses the problem is at components and I can't be sure if you can manage replacing components.
In case of a problem or clarification, don't hesitate to post me a reply before rejecting my answer.
If you are satisfied, accept my solution.
Thanks and regards

If the fuse is defective doesn't it mean that the speakers would not play? In my case it plays, just that I get it cutting off ever so often.
