Hi, I'm using a 21" dell CRT which does very nice refresh rates and resolutions. Only problem is their's a chip on the middle of the screen, which is brighter than the rest of the screen and doesnt display lines though it, just the general colour around and about.

IE if I draw a straight black line through it in paint it just displays white where the chip is, irritating when the cursor goes over it.

Was wondering if someone knew of some kind of plastic filler with the same refractive index of glass which would fix the problem.

Thanks in advance.
 
Hmm, sounds interesting, surprised spie's not got something like that in car products. Do you know the proper name of the stuff it is and how it might affect the monitor, IE will it leave a huge dark splodge or something?
 
Looked in to it a bit, unfortunately it doesn't seem like something you can just buy and apply, needs to be done with proper equipment and stuff:(.
 
Take it down to your local supermarket car park, usually some company there offering to fix your windscreen. This can't be too different :)
 
This is actually very dangerous. The vacuum in the CRT is very high. If the crack begins to spread you WILL be wearing a some nice 10mm pieces of glass in your forehead when it goes off. If it was mine I would throw it away. I have personally seen CRT fail and I would not want to be anywhere near one. CRT's implode then debris is spat out the front as it rebounds off the back off the tube. The flatter the screen the thicker the glass needs to be to cope with the negative pressure. I must add not all tubes will implode fully as some have banding protection but shards of glass still fly around.

Not to worried about it imploding, its only a surface chip apposed to a deep crack and yes its very thick glass as its a flat 21" screen (weighs 31Kg:eek:). Since I don't have a car and I'm only a poor student can anyone suggest an easy way to fix it without calling out autoglass?
 
I don't think there is an easy fix, when autoglass fix the windscreen it's structual and can still be seen, it just stops the spread. Any imperfections in glass defract light....

Even in a complete vacuum there is onlu 1 atmosphere of negative pressure and that won't cause a catastropic failure even if it cracked with thermal cycling. The glass at the neck end is only 1mm thick.... you can bounce a brick of the front of a screen and it will only chip. All that TV rubbish when someone puts there head through one ..... no chance.

Mythbusters anyone?
