Sounds like a discipline problem.

This sounds like you have some problems with your son that should be delt
with!

The screen has coatings on the surface, and when polishing it, these will be
damaged. There will be a type of blemish showing in the screen after the
polishing is done.

There are some polishing compounds that are designed for glass. You will
also need the polishing tools to do the job. This would be almost impossible
to do by hand.

There are some very serious safety issues in striking the glass surface of a
CRT. There is the danger of a serious implosion!

You should definitely do something about this problem, and very fast!

Yah sounds dangerous.

I had considered using one of those windshield repair kits available at
automotive stores. More appropriate for "bulls eye" type cracks. The
filler material may work for the scratches if flowed in with the screen
flat. As above no polishing may be possible. There's also this stuff
for repairing scratches is glasses. Just some thoughts have never tried
any of these things.

I don't know of anything that works. Recently, a watch repairer told me
that there was some new compound for filling scratches in watch crystals.
He was supposed to send me some info from the supplier but never did. You
might want to try a watch man and see what they have.

Totally agree with the discipline related approach, apparently the son is
either too young to appreciate the value of another's property or has never
been taught that fact.
Also, as noted, a severe safety situation could result with just the right
contact with the glass. These things are not to be trifled with, there is a
definitive reason why the designers and manufacturers put the safety glass
on the sets in the first place. However, persistence in hitting it with a
hard object can prove to be extremely detrimental to your child and others
in close vicinity of the set.

A friend of mine gave me a tip wich works for glass but maybe not for
coated glass.

Take a silicon cloth and use cigarette ashes, yes, I know ...
Just try it ! Magic !

Another one , wich I saw and did, wich I coudn't believe until I did it
by myself (don't do this with your screen) :

cutting glass with a pair of scisors : put a piece of glass in the
water (in a big bucket, the glass lust be totally imerged, your
scizzors as well. Cut the glass. The feeling is like if you are cutting
a shell (clamp, muscle ...)

For the end : this friend is a precision optician, working for defense,
laser beam systems for fighter aimers, etc ...
Goog luck. Try with a scratched piece of glass before doing it on your
tv maybe ...

Cutting glass with scissors?? Excuse me if I seem a touch cynical; but I
find that hard to believe....

If the glass is very thin, I would believe it.

One good way to cut glass is to the scratch line in it from a glass
cutter. Then put the sheet of glass under water, and carfully tap it on
the side that is to be removed from the desired side, as normaly done
out of the water. Or, put the glass over a wedge and carfully tap
and press on the side to come off.


As for the sisors part, I have to see that one!

I remember seeing an article about that in a 1960's issue of _Popular
Mechanics_ or some similar magazine. Never tried it myself, though.

If you can feel the scratches with your fingernail then there's not really
anything you can do. This assumes of course a standard direct view CRT TV.

If they are long and numerous, I'd also be concerned about the implosion
hazard.

Dicipline the kid or put a piece of Plexiglas over the screen to prevent
further damage (or damage to your new TV).

This seems a good enough reason to keep scissors out of reach of the
goldfish. :-))
