Repairing scratches on CRT glass?

Hey all,

Just looking for some advice on the feasibility of removing scratches from the glass of a CRT. I have a nice Sony CPD-G500 21" monitor and it has 2 scratches dead-center of it's glass. It is in beautiful condition otherwise. I've read online that trying to buff these out can be an exercise in futility with many recommending against it.

With that said, I don't have much to lose on this so I'm considering trying something like this:


Obviously, a car windshield and a CRT screen are not the same thing, and there might be anti-glare coatings to worry about here, but it'd be great if I could hear from someone with experience in trying to fix something like this, whether that experience is positive or negative.

Thanks in advance!

 

I'd probably get a junk tv and scratch it and see what happens when you try to remove the scratch first.

 

I’ve used polywatch many times to remove small scratches from crt screens. In fact I removed one today from a sony trinitron. The stuff is 20 dollars on amazon and only lasts for 2 uses max, but it works well. Scratches have to be not deep as it could polish a flat surface where a deep scratch was which will be noticeable on curved tubes.

 

It depends on how deep it is - cerium oxide goes a good job on fine scratches. For deeper scratches, you can use silicon carbide - but you should consider this a being the first step of a 2-step process since it will leave the surface looking hazy and you will then need to polish with cerium oxide for a polished finish.

 

Does it still have the anti-glare coating on it? (Does the monitor face appear relatively dark when it's off?) If so, just peel it off and run the monitor without it. The tube face will be a much lighter grey without it, but it will still look good in a dark room.
