I think the general rule is, if you can pick up a TV you should throw it away when it breaks. It might make some sense to fix a "big screen" but the parts for table top TVs are largely made from "unobtanium".
These guys used to handle some high volume TV parts but the last time I was looking for something (a tuner for a big screen) they didn't have it. http://www.mcmelectronics.com/mcm4u.html
