I purchased a panasonic pt-61lcz70 lcd rear projection tv. A week after buying it I started noticing green lines on the sides of the screen. The lines appear exactly where the screen cuts off a non hd picture. Is this normal with projection tv's? Should I call panasonic? Should I exchange the t.v. and risk getting another one with the same problem?

Most likely problem is bulb failure. Replacing the bulb is first step in any LCD rear Projection troubleshooting.
PT-61LCZ70 has a special "Super Dooper" long life lamp that costs a ton to replace. US users have 5 year warranty on the lamp assembly. Canada users can whistle for help from Panasonic Canada. There is no replacement bulb available, only expensive lamp assembly.
TV has to be completely taken apart to change the lamp. Panasonic service information is 12+ pages for lamp change instruction.
Hi , it seems you are experimenting a light engine problem.Here's how your tv works: http://www.youtube.com/watch?v=ZLLHnQ4y-wo Basically there's 3 LCD chips that create the colors and image by blending together.When these chips start to melt you will get those blue spots, pixilation even vertical lines.You will need to replace the light engine.You can find it here: http://www.discount-merchant.com/PANASONIC-521A2C52-p/1177904.htm Have a blessed one!
If its a LCD projection TV (such as Sony Wega, Hitachi, Epson, Philips,
and some Panasonic, some Mitsubishi), and the green image is in the whole
screen or just one part as a blob or a line. Is most probably that one of your
LCD Color Filters is damaged (burned out or starting to get busted), I don’t
know if you can just replace the color filter, I believe you need to
change the whole light engine system or the optical block. There are some
places around, I found some on ebay but you should definitely try on
discountdashmerchantdotcom their price range $260.00 - $330.00
