The glass on my five year old WEGA is scratched. I've looked into upgrading, but have decided to wait, and now I find that my set has been scratched up! Is there anything that can be done about it? I can feel them with my fingernail. So far I've found at least five, and four of them are very big in surface area. I can only assume my kids had something to do with it, and I'm really angry about it. My guess is that there's not much that can be done, but here's hoping.
