When I was a kid I threw
something (I had an antique erector set and various other heavy metal things to 'play' with) at our early 90's Zenith that gave it a DEEP screen gouge about 1/3 the size of a pea...It survived a good 5-10 years of me throwing various other stuff at till it was given away working when we upgraded.
I also have an early 70's Sylvania that looks like someone shot it bullseye in the center of the screen with a BB gun...Deep gouge, and it is fine...It looks like it was outside for a decade before I found it. Somehow I convinced that set to work.
Unless you plan to throw hammers at it you should be fine...If you do plan to throw hammers at it you probably have bigger problems to deal with.
