(Instead of creating yet another
Buying a TV thread, I decided to hijack Pap's. Sorry, buddy.)
My six-year old Sony TV died.

It's completely non-responsive when I try to turn it on. It acts like it's not plugged in, even though it is (and yes, I tried changing outlets, etc.). I think it's either a problem with the power source or the mother board. I'm looking into getting it fixed but it might turn out to be more expensive then it's worth, so I'm also contemplating just buying a new television.
Has the Internet finally decided if Plasma, LDC or DLP is better? My living room is fairly bright during the day (not sure if that matters). I'm looking to probably pick up at 42" set. I'm not really concerned about burn-in, as I understand that it's not a big problem these days.
My biggest concern is refresh rate. I don't really know any of the technical specifics, but I know enough to be worried that I'll get a system that doesn't play nice with my Wii.
I have a connection that can get me a really good deal on an LG TV. The Internet doesn't seem to really like LG TVs (something about poor black levels and screen uniformity). Then again, the Internet doesn't like a lot of things. Does LG really compare that badly to Panasonic/Phillips/Sony/etc? ( I prefer to stay away from "lesser brands" like Vizio and Insignia.)
Any advice would be greatly appreciated.
