Polaroid HR2500 vs. 3m 6650

[jackardiac]

So, here's my situation... I've had a Polaroid HR 2500 for the last year and a half, and it's served me well. Greats specs, as most of you know, and grabbing it for $50 on eBay was an absolute steal. But about 4-5 months ago the upper 1/5th of the panel suddenly whited out. It came and went at first, but now it just went. It only really affects me when I watch full-screen TV, but with letterboxed movies it's fine... I just cover up the white section.

At any rate, as much as I love the panel I'd rather have one with full capabilities, so I bought a 3m 6650 on eBay. The problem? No power supply. So I'm desperately looking for a way to power it up and make sure it works, then I'll be able to put the HR2500 up for sale.

Does anyone here have a suggestion / solution / extra power supply on hand?

Thanks,

Kevin
