How do you get TV, is it cable, satellite, or antenna?
If cable, do you use a set top box or does the cable come from the wall and screw into the connector on the back?
If you use a high def cable box, are you using the 5 wire component video connection between the box and the TV, or are you using HDMI?
Do you have any other sources connected to this TV, like a DVD player, and if so, does the problem happen with it?
what do you need to know i did not get your answer
I beg your pardon, I don't see where you told me anything.
How about a DVD player, do you have one?
no are you going to help me
If you press the TV's MENU button, do you see the lines on top of the menu or does the menu look OK?
How old is this TV? What's the model number?
OK, go get your refund...
