Arcade Monitor with scratch in glass Question

[Epyx]

I realized i created a gouging scratch on my monitor when I powered it up to tweak settings on my current cab project. My nail does feel a slight groove and sure enough the toothpaste trick didn't work. It blocks the distortion of the light but replaces it with a toothpaste smear line!

It is a WG D9800 which runs perfectly fine and is currently in Horizontal Mode...I ordered a 2nd today which will replace this one. My thoughts are worst case it will make a great vertical monitor as the scratch is near the bottom middle.

Anyone know of any other tricks/methods to remove a scratch on an arcade monitor that you can just feel with a nail? Or am I SOL?

Thanks in advance!

jewelers rouge sometimes can get it out, but if it's deep, yer SOL

I wonder if that epoxy material auto glass repair shops use for dings would work?

Thanks guys. I just called a glass repair shop and he said that unfortunately, due to it being tempered glass conventional repair methods won't work...either put up with the scratch or replace it

The scratch itself is small...its what it does to the light below (distorts it to a blurry line almost 3x the width of the scratch) that is annoying.

I have already ordered another monitor and will use this as a vertical...ill also try a small strip of tape in an attempt to have the light not get distorted.

Supposedly cerium oxide can be used to polish out a scratch on glass.

I just bought 8 oz of the stuff on eBay to try to get scratches off the glass from a cocktail cab I am restoring - and unfortunately it didn't do much at all. However, I was using it with a polishing pad on an orbital sander.

I found some info that suggested it MIGHT work if you first use some high grit sandpaper - 1500 or 3000 grit, and then use the cerium oxide to do a final polish. Seems I might have had better luck if used a rubber polishing pad in a high speed drill and used some serious elbow grease...?

I basically decided to just buy a new piece of glass, but with a monitor it might be worth the time and effort.

I read somewhere that for scratches in LCD panels, you can fill the scratch in with petroleum jelly as a reasonable solution. Might try that?

Ill give both those suggestions a try, thanks!

I didn't think I needed to start a new thread, but I *just* picked up a TV for my Project (yay me) and noticed when I got it home that it had a 2" scratch in the screen.  Not certain if it's deep or not, but I can definitely see it.  What's the verdict on your repair, Epyx?  Also, what's the 'toothpaste trick'?

If you attempt a repair, be prepared to make it way worse.  What often seems to happen is that, in the process of buffing the scratch out, you polish the rest of the surface surrounding it to a finish that doesn't match the rest of the CRT face.  If the scratch is minor, I'd just live with it or try one of the non-permanent "fixes" like filling it with petroleum jelly.  If it's so bad you're about to toss the tube, anyway, then have at.

If it's bad and you need a monitor, you could attempt a tube swap from a TV or other arcade monitor as the D9800 is a fairly capable boardset.  You might have to swap the yoke, too, though, which complicates things a little.

If it looks really bad, I'm going to try the petroleum jelly trick.  I think I might be putting some tinted plexi in front of it anyway, so I'm not certain if that will make it more or less visible.  I'm not going to make any snap judgments now.  I'll get it assembled and then consider the options.

Thanks for the input!

have used automotive buffing compound, and LOTS of elbow grease for minor scratches.
