What is the best way to remove a scratch from a plasma flat screen?

It's about 4 inches long & is quite noticeable on very dark scenes.

Is the panel glass on the front of the television? I would probably look in to glass polish or some good quality metal polish rather, meguiars or the like.

Yeah it's glass. I was hoovering and took the plug out, wound it up & hit the tv when moving it away. The picture's fine. Can't tell if it's just a scratch or if it's cracked though.

Wow how did you manage to scratch plasma glass?

Be careful when rubbing or polishing it out because the screen might have a protective antu-reflection coating. if you rob that away you will gate a patch.

I think the most likely outcome of a repair attempt is making it worse.

Even a person with years of scratch removal skill would struggle to produce a perfect result, what chance a beginner to the technique?

It's only a thin sheet of glass, nothing special, and scratches as easy as any other glass.

If you have the nerve you could try some glass scratch remover that they use on car windscreens. I got some for my windscreen but it was only for surface scratches, the ones that don't click when you run your finger nail over them. I had never done anything like this before, I just carried it out following the instructions. You use a drill on very low speed making sure the paste and pad is wet at all times checking the glass making sure it doesn't get too hot.

Pretty sure it gave other uses for this polish, a TV screen was one of them.

I wouldn't hesitate in doing it, but then I have used it before.
