Re: SCRATCHED TV SCREEN
I was researching your problem and I found a warning that you may want to heed on http://www.answerbag.com/q_view/577.
"Scratched glass under compression can be dangerous (more prone to failure). In televisions, the glass is like a giant light bulb
that is completely emptied of air, so it is always ready to implode
like a submarine getting crushed in a hollywood movie. A scratch can be
a a weak spot and implosion can send glass flying when it collides
together. Although the flying glass is just tiny shards that can,t
penetrate skin, only one has to hit your eye to make it a big deal. So
safety glass might be a good idea when working on the tube that close.
You will be able to make the scratch duller with some work."
The actual answer is that you would have to have the front screen replaced. It is opticaly coated. If you try using any type of polishing compounds the coating will be removed. There will probably be ripples and reflections where you tried to do the polishing. The replacement part is made of acrylic with an optical coating. It is expensive.
If you had an LCD screen, the compete panel would have to be replaced. This would be terribly expensive!

By the looks of that picture, it's hard for me to believe that the scratch is not on the outside of the protective plexiglass screen. However, you can remove the protective screen w/o negative effect of the picture. In fact, it will probably reduce the glare from light on the screen. If, in fact, the scratch is still seen w/o the protective screen installed, then it is the lenticular screen that is scratched.
The lenticular screen is the one with the vertical grooves from top to bottom in it. The fresnal is the back screen that appears to have been lathed in a circular pattern.
Well, unfortunately, there isn't much you can do about it. The cost of a new screen and installation would be almost as much as a new TV itself, so if the scratch doesnt deter you from watching TV, then I suggest just leave it be. There are a couple of scratch removing products (abrasives) on the market, but if you have no experience in this, then you'd only make the scratch worse...
I replaced the screen on my 62 inch projection TV for about $50 and the the picture quality is good! Have a sheet of plexiglass cut to the EXACT size needed. BEFORE installation it MUST be frosted on both sides by either a fine particle sandblaster or by sanding it VERTICALLY on BOTH sides with a power sander and a fine grade paper.
If this is only an OUTER protective screen and the image is projected on the inner screen then DO NOT frost the replacement screen, just install it.
