Greetings-
I have a Sharp Aquos LC-26D40U purchased new in December 2007 (warranty expired). Recently it began this: When turned on, the picture is fine and everything operates as it should. After a few minutes, the screen begins acting up as seen in the photos below. At first, if you turn it off for a few minutes and then turn back on, the screen returns to normal until it warms back up again. Obviously something heat related.
With the nature of the problem, I suspected and replaced the T-CON board, but that didn't work. I also cleaned and tightened all ribbon cables and their connections. Mainboard?
This happens regardless of input selected. If the menu is selected, it is also distorted.
(BTW- all other artifacts on screen only show up in photo. Not actually there)
Any help is greatly appreciated.
Best,
David
