I have an Insignia NS-42L550A11. This is the 42" LCD 1080p 120hz model. I am starting to get black lines across the screen that are intermittent. Also there is some occasional ghosting that occurs, the best way I can describe this is that is is similar to how the bad guy in the Riddick Chronicles moves. These symptoms are not continuous but do get worse as use goes on. When the TV is turned on cold usually takes about 5-10 minutes for them to start once it is warm.
BB wants $150 to come out to "look" at it. I have found a few websites with parts but I am just not sure what part to change.
I appreciate any help and will try to give more details as best I can.
