I bought my dad a Mitsubishi model no. LT-40133. It's a 40" slimline tv. I bought it in dec. of '08. It was a Christmas present,
Anyway, about 6 mths. ago, When you first turn it on, you get vertical lines, It starts about 3" from the left and it goes all the way to center of tv. I read some post on the internet, most people say its the t con board. The vertical lines will last about 15 to 20 minutes and then disappear. It does this every time the tv is off for a while.
6 mths. later it's still doing the same thing.
Does anybody know what could be causing these? And could it be the t con board? If so, is this an easy fix?
