After viewing my HDTV for about 30 minutes the top area of the screen pixels out. If I turn it off for a few minutes the picture will be ok but the problem occurs again. The HDTV is four years, is the TV about to go out or can it be fixed? I have read the troubleshooting guide but there is no topic on the owner manual for this problem.

Tries websites like Shopjimmy.com,Ebay.com to buy a refurbish board that call T-CON board to do a replacement.This T-CON board sit in the middle at the bottom of the tv LCD screen panel.This T-CON board control all the picture pixels going throught to the tv LCD screen panel.
Tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish board that call the T-CON board for the replacement.This board sit in the middle at the bottom of the LCD screen panel.This T-CON board only job are to decodering picture pixels dots only before it show up to the LCD screen panel.
This is because full pixels of your TV is not getting invoked at the beginning .If you are able to view the picture as normal after 1 or 2 minutes, its fine.Else you need to call to service center and get this problem fixed.
