Question about Canon Office Equipment & Supplies
An area of the projected image shows weird "maze like" lines, in the green to blue color range.. all lines are 90 degrees to each other, very pattern-like, not random squigles.. i really don't know how else to describe this..
the lines appear brighter depending on the actual image color in the problem area.. the lines do not change position between the wide and normal settings, so i don't think it's a signal transmission issue from the video source..

I have the exact same problem as sal1965. Does anyone know which circuit board may have a problem?

SOURCE: Long time to power up video
My Sony KP-53XBR200 will not display any video (even from the tuner) except the internal display until it sees a video input on one of the video jacks on the back after a power hit.
I solved this by putting a video cable from Monitor out to Video 4 in (unused for other video). Voilla! Instant video on. This may not be your issue, but it fixed my set!

If your seeing vertical line across the screen you need to check the components in the vertical stage as well as the vertical IC could be bad, or the yoke could open.
Also check if any voltage reaching the vertical stage.
Was this help full.

SOURCE: NEC Lt240 prblem
You could check in the Service Menu if your RGB is the same percentage and at the same run rate.
The run rate is normally 45-60 and the percentage on 50.
I would however recommend that you take it to a NEC agent to get it serviced.
If this doesn't fix it , then you will be looking at a new Mainboard.
Thanks for using Fixya and good luck.

Can you connect a computer (vga) signal to this projector? I'd like to know what your "white" computer screen does on the projector....example, Excel spreadsheet....
I am leaning towards these problems, a bad video card...or worse delamination of one of your LCD panels and possible polarizer burn in the optical engine.
