quote: Carsten Kurz Can you tell us more?
This was a small, neighborhood theater that sometimes calls me when they have a problem. They reported a "blue spot" in the upper left quadrant of the screen. At the time, I was getting ready to leave town for another job, so I didn't have a lot of time to deal with it. I went down to the theater & I did see what appeared to be a 'stuck' blue pixel on the screen. It wasn't 'horrible', but it was definitely there & once you saw it, it was hard to ignore.
As the theater was short on money, and I was short on time & didn't want to spend all night at the theater, ( I had a 3am airport shuttle pick-up the following day) I decided to do the checkerboard thing as sort of a 'Hail Mary' fix for them. Not finding an alternating checkerboard pattern on their projectorthingy (an NEC) I created one for them & told the to let it run until they opened the next day. (so it ran about 14 hrs) I got a text message the next day that the 'blue pixel' was gone. This was about two years ago, and it's never come back.
I agree with you that it shouldn't make a difference, & I wouldn't be surprised if this doesn't work all the time, but all I can say is that on this occasion, it "fixed" their problem.
The theater was operating on a very tight budget, so if this hadn't worked, they probably would have just left the pixel on screen. In fact, I never even billed them for my last minute late night 'emergency' call, so as far as I'm concerned, they got they're moneys-worth. (Although I recently did another emergency job for them which saved them from loosing a sold-out show, for which they paid me almost double what I billed them, so "it's all good".)
