SOURCE: Remote control
You need to resurface the contacts. Here's how you do it:
First, disassemble the remote. Clean the black foil pads on the circuit board with rubbing alcohol. Now take a #2 pencil and a razor and shave the graphite from the "lead" onto a piece of paper (hold the blade perpendicular to the lead, this results in a finer powder). Now that you have a nice pile of powdered graphite, blot a Q-Tip into it to saturate the cotton with graphite. Rub the graphite onto the little black pads on the rubber button membrane, and be sure to apply more graphite to the Q-Tip every 2 to 3 buttons. Blow off any excess graphite. reassemble remote and test.

Hiya i dont recommend that you try this without experience but if you want to give it a bash then great. (please keep in mind that slipping with meter probes could make things much worse and there is risk of shock) Thats my disclaim :) ... On the power board/ PC board, look for the 2 largest capacitors. The y will be PS caps. With a multi meter set to DC, test acroos one cap then the other (one at a time) There voltages should be the same in value more or less and the voltage should be around 30- 40 V. There will also be another supply of around 12V but cannot tell you where to look for that without seeing. If all fails, send me a pic and will point you in direction. Best of luck

If you can believe what they say about the specs...
Register and download the manual for free at retrevo.com
Bear in mind the power spec is at >>>> 10% <<<< THD without any bandwidht specified. THAT's a lot of distortion stated in a meaningless fashion to convince you to part with the money.
If one looks at the power CONSUMPTION figure (43 watts), one can conclude that the audio power spec is totally fabricated. NO device puts out more power than it consumes.
That is not to say it won't sound good and loud in certain settings and conditions, but this is not, say, a Bose Acoustic Wave Music System. After a certain volume demand it will just be annoying instead of entertaining. That's why they called this class of product a Ghetto Blaster.
I see one sold for $70 last year...
