I realize that doesn't help much in your situation.

Where I worked, we got in truckloads of store-return TVs. My boss wouldn't let me spend time on TVs that wouldn't sell for much in our retail store. So Westinghouse, Polaroid, Element, etc, I just looked them over. If I didn't have them fixed in about 30 minutes, they got torn down for parts on the eBay store. Funny, off-brand parts (at that time) sold for more than the big names- so that was further motivation to not spend much time on them.

Interesting. Do you think it might be worth a shot at buying another power supply/inverter board from ebay for this unit and seeing if that fixes the issue?
