Are you
saying that "phosphor screen burn" on a CRT can be fixed by a
strong exposure to sunlight?
That sounds too bizarre - I would expect that strong
exposure to the sun
would simply fade the phosphors even more...
sure, . . .
just burn the rest of the screen to match, or until the percentage of
difference is less noticeable
Go to reverse video, and leave a Visicalc L-bar on for a long time.
Hi Fred
I suspect that you are right. Still, without having a light meter handy
we'd just be guessing. One of my terminals someplace has a mild burn
on it from some menu. Next time I see it, I'll place it in the sun but
mask of a section with foil. If it is just making things uniformly dim,
the covered section will be brighter.
Even so, it might better to get a uniform dimming than some burn
letters.
I have an old oscilloscope that has a hard burn. It looks like there
is no phospher at all where the burn is. I doubt this could be recovered.
