Damaged CRT glass

[RolyL]

I have managed to scratch the front of my iiyama 17" CRT. I have spoken to their tech-support and they think I have taken off some of the anti-static filter-coating of the glass. There is a nasty splodge right in the centre of my monitor and I'd like to do something about it. iiyama won't repair it, only replace the entire tube and charge me £150 for the privilege. Any suggestions?

Sounds to me like you have stuffed the monitor completely... the only option you realy have is to take it to a panel shop and get the guys there to try and buff the scratch out like they would out of your windscreen if you scratched that. I don't know what this will do tho the tube because I have never had to do it...LOL. Good luck!

Folks, CRTs are not car windscreens. CRTs are under substantial tension, not to mention
the vacuum inside. Damage to the glass sets the whole thing up for structural collapse.
A CRT with damaged glass is a ticking time bomb, messing around with it
to camouflage the damage only increases the risk of an implosion.

I think the glass itself is fine... it's the anti-static coating that has been slightly damaged. Is it possible to reapply this without replacing the entire tube?

No they're not... Would it really be that volitile?
If you are buffing out surface scratches I would imagine it would be safe, but like I said I have never tried it, nor would I... I would just replace the tube or get a new monitor.
I will make sure not to be the first to try it if it really could be that volitile.

You're probably stuck with it. To buff it out, you'd have to buff off *all* of the anti-static coating... I'd live with it if I were you.

flot is right, you can't just apply a part of the coating after it has been damaged. I'm not certain whether it's even possible (or wise) to remove the whole coating and re-apply it.

BTW, don't let peter scare you. The damage you described does not sound like any form of structural damage. Otherwise you'd probably already have noticed it

Not being able to reapply the coating seems to be the impression iiyama are suggesting. Pity really, as structurally the monitor is fine. Oh well, I'll just have to live with it :-(
