I have a 12+ year old Sony Bravia 40" S something. It's been starting to crap out with white shading getting larger and larger when turned on with the cable box off. You can't really notice the white while the TV is on. Anyways I noticed 2 really deep scratches recently and 1 not so deep scratch on the screen. I'm the only one who has ever cleaned the screen. The wife has never touched it. My 9 year old kid said he hasn't touched it and I believe him. Anyways, the scratches are pretty straight. Is it possible that the screen manifests a scratch from something going on under the panel? I'm about ready to replace it and was just wondering if any of y'all have seen anything like this?
