This may sound a bit strange, but every so often when I flip off my overhead fluorescent kitchen light my home theater (located in my great room about 20 feet away) shuts off. The setup consists of:

Samsung 40" LNT-4066F LCD
Onkyo TX-SR674 receiver
Oppo DV-981HD DVD player
KEF KHT 3005 speakers
Verizon Fios HD DVR set-top box
Monster PowerCenter HTS 1000

After 5-10 seconds, everything starts back up (the set-top box has to go thru a re-boot cycle). It's annoying every time it happens. It seems to happen more often if I flip off the kitchen light quickly.

I'm no expert, but my guess is that the PowerCenter is sensing a voltage fluctuation/surge, and shuts down as a protective mechanism.

I have spoken with a local home theater store and with Monster and have gotten variable/vague suggestions.

My question is, would the addition of a modest battery backup unit (say something like a $100 Belkin 750-AVR), into which I would plug the Monster PowerCenter, likely solve my problem? I've looked online at a variety of 'home theater power protection' devices, but many are just voltage-conditioning devices; they don't provide battery backup. The ones that do provide battery backup are significantly more expensive. I'm assuming my Monster PowerCenter is adequate at cleaning up dirty power (although I realize it's not a high-end model), so would the addition of just a basic UPS unit be all I should need at this point?

Thanks for your help.

Most UPSs don't have near the power you'll need. They also make a simulated sine wave, which will actually hurt your noise problem.

Plug the Monster into a different receptacle. One that is not on the same circuit as the kitchen.
