After exhausting all possibilities that there was a problem with my new Marquee 8000 projector, I turned on the screen.


MY SCREEN:

96"w by 52"h Studiotek 130 AT-1.5 "snapper" wall mount screen. The screen was installed around mid-March


WHAT I'M SEEING:

very faint vertical & horizontal lines/bands 1/2 to 1" wide forming a grid, about 6-8" apart..mostly visible during bright, daylight scenes or in white screen test patterns (and red screen and green screen, less so on blue). The vertical bands appear more visible than the horizontal. The lines are most prominent in the upper LH quadrant of the screen. The bands/grid are not visible without projecting a light onto the screen. When they're visible, they almost look like a slight fold in the screen or variance in the screen's reflective property.


Very strange. Am I losing it? Anybody seen anything like this before? I know screens take some time to stretch out, but is this normal? I'll give Stewart a call later today and ask some questions there as well.


Thanks in advance for any thoughts.

Dear Paul,


I think I can explain the vertical lines but I can not explain the horizontal lines. The vertical lines may be slight packing impressions in the screen surface. The screen fabric is shipped rolled up around a packing tube . There is also some soft thick packing tissue type paper rolled up in the screen. These packing impressions will normally smooth out in a few days. I must say, the horizontal lines have me stumped. One thing I would like to suggest is that you tape on the screen surface a piece of white paper over the a troubled horizontal line. Use masking tape as it will not damage the Studiotek finish, Then, from at least 8 feet away from the image, evaluate if the line still exist. I would like to eliminate the possibility that the projector's Cross Hatch test pattern has not been burned onto your CRT tubes. If lines are still there, then call Stewart Filmscreen in the morning and we will expedite a new replacement screen fabric to you. Also, if the packing lines fail to smooth out we will replace the screen.


The toll free number is: 800 762-4999, Monday through Friday, 7:00 am to 5:00 pm PT.


Regards,


Don

Don,

Thanks for your reply. I've actually been remiss in keeping current on this post. Here's what's happened since I posted initially.


I exhausted all possibilities that the problem was with my projector by shutting it off and hitting the screen with a floodlight (kind you use for painting, etc.). There were those lines again! I used Post-It notes to mark a few off and turned the PJ back on...they didn't match a single test grid on the PJ.


Next morning I contacted my dealer and Stewart's 1-800. The gentleman I spoke with at Stewart was equally stumped as to how I could be seeing what I was seeing, but was quick to offer a substitution/replacement screen fabric. Arrangements are under way for the swap-out. My dealer will be contacting Stewart on Monday.


Don, I've got to say that Scott Kimber at Stewart was great to speak with and his "we're not happy until you're happy" attitude/approach was downright refreshing. Thanks for such great service!
