Projection T... Master
Re: Scratched Glass Television Screen
You will need to replace the tube there is no screen its the actual face of the picture tube. very expensive around 500 for a new tube that size. I have a source for used rebuilt tubes for around 275.00 shipping included. If interested let me know the model number and I will inquire as to the availability.

Hitachi has two screens (other than a clear screen protector some have) The two inner screens are only sold as a pair---over 400) If the mirror behind them is damaged look to see no glass has scratched the inner screen as it will show---Mirror can be available either from Hitachi or some after market places have them.
If the mirror--Google the model number with "replacement mirror"
I have a rear projection TV that I thought had a scratch as well. Upon closer examination and several attempts to clean, I discovered that there was a spider web behind the screan in front of the color projectors. I carefully removed the screen and gently cleaned the spider web from the screen. Presto no more scratches.
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.
I would suggest that you clean the lenses and then apply some of the " As Seen on TV " lens scratch remover. I have used this product many times and it seems to work very well. If you have scratches on the screen. you may need to replace the screen as I have not found a good product to correct this problem. I hope this has helped.
