I am getting ready to try leveling the wear on my green tube in my DTV-1100 / 1209s. I have pretty bad 4:3 wear, in a small area, off center on the tube face. Luckily, there only seems to be one wear pattern.
I plan to wipe my setup completely, expand the raster up to 3-4 mm from the edge of the tube face, and use GIMP or something similar to draw a pattern and display it. I'll gradually increase to full brightness and high output mode (can't remember what barco calls it) over the course of an hour or so, and check on it when I can to touch up the pattern or change geometry slightly if the projector drifts. I will also defocus the tube to avoid burning in scanlines.
For those who have done some wear leveling, do you have any other tips? Is it best to use a sharp-edged pattern, letting the electronic defocusing take care of the edge to prevent burn there, or should I use a gaussian blur over the half-inch or so at the edge of my wear pattern?
I don't know how successful I will be, but others seem to have fair results, and it's much cheaper than a new tube!
