![]() Lots of old dodges like Beeswax and Oil,--Think covering scratches on higly polished wood surfaces.....
Maybe Brasso will polish it out--But will also make for a shiny area rather than the matte surface of usual LCD....

![]() Try a clean pencil eraser. It works better than you'd think.

![]() Toothpaste can help buff some scratches out. Any buffing compound ok for plastic finishes should work too.

![]() I wonder, how those windshield damages are filled, with that special glue, it wouldn't work on an LCD screen as well?

![]() Matt a few years ago we had those machines who could buff a CD with some plactic material, it would remove the scratches from the surface of a CD. You could simply get that machine, it has a very fast rotating motor on which some plastic material is connected. Once it comes in contact with the surface you want to remove scratches from, it fills those scratches up with plastic. I’m not sure if we can find those easily today though.

![]() You can remove the scratch but its going to remove the matte surface layer too using any rubbing compound.

![]() I use 91% isopropyl alcohol with a cue tip and rub straight along the scratch since i get
tv's from a recyling place most have some scratches but i have had good luck with this technique if you try this, test on a small spot and if it makes things worse then do not do the rest of the scratches with this technique but for almost every tv i have worked on this has worked great for me |

![]() There was silicone heatsink compound (clear), instead of the newer white stuff, made by GC electronics, it works well. You just smear it in the scratch with your finger, then buff off the rest along the scratch with a microfiber cloth. It was like Vaseline (petro jelly), not sure if that the Vaseline would work, as it's a petro product, and might react to the plastic, but the GC silicone heat sink compound worked like magic when we used it. one thing, it never sets, so you periodically might have to reapply if you clean the rest of the screen, but we were shocked how well it worked. The scratches literally disappeared. You could try the Vaseline on a junk screen and see if it does the same thing, and not eat the plastic if you can't locate any GC Electronics clear heat sink compound

![]() BTW, this tip came from another tech, he said he read it on some forum but we just happened to have some of that clear stuff in stock. I can't remember what forum or who he got the tip from, sorry to whoever originally discovered this.
