I have scrached my panasonic plasma tv this

You can take the guts out, panel and all and replace the protection screen (PN: TTEA0222). It's quite a job, however, there are only 4 screws typically holding the Plasma panel in place. It's a matter of taking some notes a photos as you proceed through the disassembly process. May take you an hour or two and you will need to keep dirt and dust from in between the new screen and the panel. Also, this is a 2 man job. You need to be very careful picking the panel up. Too much pressure or twisting can crack the panel. I hope this was of some help.

The only way to repair it is to replace the panel...very expensive.
