Insignia NS-42P650A11 buffer issue?

[blobula]

When watching my tv via HDMI random white vertical lines on the left side of the screen flicker or flash briefly and then go away for awhile. It's very sporadic. Other times when I turn the tv on there are some black vertical lines the remain on the left side of the screen. If I turn the tv off for awhile then turn it back on they aren't there.

What part could possibly be going wrong? Y-Buffer?

If you're lucky it's buffers but more likely panel, especially if the vertical lines are pixel-width.
