How do I fix rolling horizontal lines on my brand new Proscan TV?

SOURCE: LCD TV with horizontal lines rolling up screen

Find someone in an area that the Company will ship to and send them the money to get the replacement board. then give them the shipping address and have them send it to you . I would be willing to help if all it will cost me is the time. You would have to take care of the E-Bay Bill and The shipping costs from my location to yours.

if u r connected to an ant. it is due to poor signals from the ant so get a booster or amplifier for the ant.

SOURCE: We also have a Vizio with red horizontal lines and our TV is new

It's possible that the motherboard or the controller board for the screen is defective. At this point, I would use the warranty from Vizio. It should be no doubt that it covered. Here's the info you will need from the Vizio web site.

Based on reported problems with Samsung LCD tvs, It is probably one of three problems:
Separation of layers of the LCD panel;
A defective LVDS cable connection;
A defective T-Con circuit board.
If light hand pressure on the affected area on the LCD panel changes the problem, its the defective panel. If not, manipulating the LVDS cable will reveal the cable defect. If not, coolant spray applied to the T-Con circuit board should reveal if it is defective by temporarily alleviating the problem. Dont remove the back cover if you dont know how to protect yourself from electrical shock hazards. There can be more than 1000 volts in the backlight inverter area.
