Question about Gateway GTW-P42M303 42 in. Plasma Television

1 Answer

Blue vertical lines across the top of the screen

When I turn the TV on, blue vertical lines about three inches wide, that look like a bar code, appear across the entire top of the screen. Some of them will slowly start to extend down the screen. When I have a picture on the screen, the lines are still there and the picture color appears distorted as if the contrast is turned way up. About a month ago I attached a digital antenna converter through the coaxial (RF) input. Is this a hardware or software problem and is there any way I can re-set the screen?

G'Day!

Unfortunately, what you're describing is a repair issue. You won't be able to address the problem with troubleshooting. There is a part inside the TV that needs to be replaced. If you're under warranty, this will cost you nothing. If you're not under warranty the cost will likely be a minimum of $200 parts and labor. However, be warned that the cost could be considerably higher.


I hope I've provided you useful assistance and that this information allows you to make an informed decision as to how to proceed from here. Please be sure to vote on my response. I hope I've earned a good rating from you today.

Please post a comment if you need additional assistance so that I can help you further.
