I've got a 46" Sony KPR-4600. This is an older unit, but it still works great. I had to move it the other day to my new home, and when I unloaded it and turned it on I noticed a stress crack within the screen. After looking at the screen, I'm pretty sure I can simply remove the plastic and put a new plastic screen in it. Does anybody know of a place I could buy a new screen for this unit?
