do not spent too much $$$ on fixing it, 42" (LCD's & Plasmas) tv's are fairly cheap now days if you shop around + then there would be no more replacment cost of lamps.
I have a Panasonic PT-44LCX65/PT and need to know definitively whether this TV has a color wheel or not. I am in dispute with a TV repair service that said they replaced the color wheel - but have since been told that's impossible because this model doesn't have a color wheel. I would so appreciate any help from any TV experts out there.
