Colorful Vertical Lines

[lisamorrison508]

Hi. I have a Sanyo HDMI TV. There are blue, green, and purple vertical lines blocking half my screen. Can you tell me what to do, please?

Most likely vertical lines caused by a bad T-Con board. I suggest you contact your manufacturer if this is still under warranty so they can help you with the repair, or if not, contact any local repairman and have them check the board for any obvious damage.
