Hello,

Yes, it's a screen problem. It could be a loose connection of the LCD and the motherboard or the lid lights gone bad. You can fix that by either resetting the connection of the screen and the motherboard or replacing the whole screen. You would need a technician to do that.

T con board is responsible for the image you see on screen as well as any anomalies.

Thanks for the photos, it looks like an internal adjustment is required to the ramp generator which controls the sequence for the screen to refresh itself from a previous image to a new image. This is a precise setting & also a software update may be necessary to cure the problem. These settings are on the Y-Sutain board & need to be accurate.If this procedure does not cure the problem then the screen will need replacing. As it will out of warranty, it would be best to contact a local repair centre & ask for an estimate to try & set these adjustments for you.
