I bought a rather nice Sony CPD-200ES 17" Trinitron monitor today at a used
computer store. Price was right and the CRT is in fabulous condition
regarding image quality (Bright, sharp focus, etc). However, the purplish
anti-glare coating is coming off in many spots. I mean all over - Not just
in one area. Guess this must be why it was dumped at the used computer
place.

Any quick tips on removing the rest of the coating completely and easily?
I've already been wiping away with a paper towel and Windex and it does
slightly remove the coating, but it takes a lot of scrubbing.

Thanks,
-Steve

You can try alcohol. Try regular medical grade isopropyl alcohol, but do not
use anything stonger than denatured alcohol. - Reinhart

I am reading from a can of spray on anti-glare coating.
It states the only way to remove it once dry is with a razor blade. I guess
a stanley knife or exacto blade would be the way to go.

The use of cleaners that have strong solvents, or the use of SOS pads,
steel wool, and abrasive cleaners will remove the anti glare. But there
is a chance with some of these that the CRT glass can also be scratched.
DO NOT use blades or sharp tools to the surface of the CRT.

The anti glare will come off without scratching the CRT glass if you use
a simonize type polish on it that is used to remove the scratches from
paint. This will take a lot of polishing, but it will take it off, and
leave the glass surface without any scratches. You can use a polishing
wheel, as what is used for simonizing a car. This will do it faster.

If you want to do a real clean and easy job to the corners, you should
remove the CRT. Removing the CRT will be the job for someone who is
properly trained and equipped for this type of work! Many adjustments
may have to be re-done if the CRT is removed, and re-installed.

It is impossible to re-coat the CRT glass once the anti glare coating is
removed. This is put on using high vacuum vaporization equipment on the
face of the tube, before the tube is fully built.

Thanks for the tips. I thought about polishing compound and that sounds
like the best route.

As far as removing the CRT from the bezel - Shouldn't be a big deal. I've
done that before and I can yank the entire thing without having to move the
yoke or ground strap. Four bolts and a couple small phillips screws and the
entire chassis and tube will come out.

Carburetor cleaner or laquer thinner help. The only problem is that both
will turn the plastic monitor furniture into sticky goo. So you have to
take the plastic away to use these harsher assistants.

That's a good tip, shouldn't be too hard to remove the guts from the case to
clean, I've done it a few times. I hate those anti glare coatings, they
almost always reduce the image quality and they're so easily damaged.

I did notice that the image looks a little "warmer" with the coating and
"cooler" in spots where the coating is gone. Only a slight difference, but
it is noticable.

I'm going to pick up some thinner and try that trick. I've tried all of the
cleaners I have in the house and I guess they aren't harsh enough!
