I've had my 65833 for about 3 weeks now, every 4-5 days or so I get a weird artifact on the left side of the screen, looks almost like a piece of dust or hair but magnified like it's on the lamp itself.

It shows up for a few days across all inputs, but then goes away for about the same length of time that is was there. This has been happening since I got the display.

I'm hoping it's just a problem with the lamp, that way it'd be and easy fix.

Here's a pic of the artifact.
