Never had this on my CRT,
Did you have a direct view CRT or a CRT based RPTV?
What I use SSE (Silk Screen Effect) to describe is this.
In order to decrease reflections, increase contrast, and increase brightness for the viewer of a RPTV a special type of "fresnel lens" screen is used. One layer of the screen has grooves cut to reject external light, and to concentrate projected light in the normal viewing area.
The unintended side effect is that if your attention shifts from the image to the screen itself you see the pattern of the "fresnel" grooves. It's my impression that over the past four years the "pattern" has gotten finer and more regular in appearance.
Some people, probably with their contrast turned way up, see sparkles too. I assume that's the result of too much brightness reflecting off of the "fresnel" grooves.
Others describe a very light silk cloth stretched over the image. That's what I see, but the cloth seems to me to be under the image.
Maybe this will also help.Silk Screen Effect (SSE)
guess I need to get a Pro Calib. done.
Anyone know of a Pro calibrator in the Little Rock AR. area?
A very good calibrator may be able to make SSE less noticeable, but it's not a sure thing. UMR is outstanding and lives in Texas. I don't know if he travels to Little Rock, but it's possible.
If you haven't tried it yet, you might want to get a copy of the DVE calibration disk and try that first. Check the Eliab link at the bottom of my post.
