Mitsubishi BPC "spare"

[Reece]

A guy I know gave me another TV some time back which I repaired and this time had this Mitusbishi that he wanted $20 for. I bought it to keep as a spare in case one of my normal "house" TV's goes out. It works OK although it's missing the power switch, but the universal remote luckily was programmed enough to operate it and to get the on-screen menus. Here I'm running it from rabbit ears through a Zenith digital-to-analog box. It gets a decent picture for what it is. It's a model C3-27209, built in 1997. Says made in USA!? My question is: if it starts to go bad, and I'm crazy enough to go into it (which doesn't seem likely), what do these sets typically crap out on?
