Hello, all. About a month ago we started noticing these strange vertical lines show up on our tv, sometimes they go away after a period of time, but are consistently visible when we first turn the tv on. anyone seen anything like this?

the lines are in groups of 6 and are blue, red, yellow and green scattered across the screen.

here is the tv model: LG 42PQ30
