This week I started seeing a pattern of lines flashing on the screen occasionally while watching movies.
The first few times I noticed it there were horizontal bands of them that would appear and disappear quickly.
Since then it seems to have gotten progressively worse, and now it is clear that its a whole rectangle of lines. The rectangle pattern flashes for a bit and then goes away. Sometimes only for a second or two, and sometimes for much longer.
It happens regardless of which input is used, and does not matter if there is an external signal or not. I have removed my moome card and put the projector on Input-A with no signal attached and it still shows up on the test patterns.
The lines disrupt video and the test patterns generated by the projector, but do not affect the menu text or text on the test patterns. It is interesting that the size of the rectangle corresponds to the area used to display text on the test patterns and that the lines precisely match the spacing of the test pattern grid.
Is it possibly a malfunction where whatever is used to display the on screen text is freaking out and showing these lines when it shouldn't be showing anything?
I did try toggling the "Status" option which suppresses some of the on screen text but that didnt change the behavior.Full Resolution Image - 631KBAVI Video (Right Click Link and Save) - 50MB
Ignore the ground loop line - thats just the sync between the projector and the camera.
