This is just MHO, but I'd stay very far away from Philips TVs.
I bought a new one that crapped out right after the warranty (naturally), and they wouldn't fix it (naturally). That's not what pissed me off, though. After doing a bit of research on the web, I found that the particular model I had failed the exact same way my TV failed for a ton of people. So many complaints about it, in fact, that if I did my research before buying, I would have never bought the damn thing. Hell, I have Sony's going on 15 years. TV's aren't supposed to die at the rate their TV's do. The fact that these are refurbished just tells me that they still have crappy Quality Control and are still selling defective electronic equipment.
I don't know what happened to Philips, but they used to have a good name in electronics, and now, they aren't worth the trouble. All I can tell you is their customer service sucks, their product sucks, and there are a LOT of angry people out there that complain about Philips on a regular basis.
Do a search on this model and see what tends to fail on the machine. I'll bet it's a problem with the motherboard, with a bad connection or resistor that needs to be replaced.
No thanks, woot.
