I bought a couple of TVs at Walmart. Good price. One fer me, one fer Mum. About a month ago, white lines about 4" in height at the top of my screen. I was washing Mum's floors the other day and heard sommat on the TV and went in to see it. Same deal on her TV. Still under warranty. But, odd. I am wondering if it has sommat to do with the new HD or whatever.

Anyone else?

I can still watch TV, but....
