Vizio e550i-b2; thin dark horizontal line across screen
I have a Vizio E550i-b2 television. It is about two years old now. Today I noticed a faint horizontal line about five inches from the bottom of the screen. It is not a typical colored line (red nor white) but just a thin line that is darker than the rest of the tv. Maybe a quarter of an inch thick. Also, the line does not go all the way across. It starts on the right side and ends a few inches before it reaches the left side. What could this be?
**I am finding replacement boards all over the internet, but cannot find a replacement LCD panel anywhere. Are these not available?**
Is this a good question?
