I have a 17" RCA Portable TV from around 1960 or so that was given to me and it didn't power up when I first got it, turned out to be a bad thermistor in the power supply circuit, bypassed the thermistor and the TV powered right up and the TV worked as it sat with all of the original parts and tubes in place yet, the only problem I had was that the vertical is slightly jumpy but I attribute that to the fact that there are 6 paper caps in the TV (4 of them in the vertical circuit) that need changing out, but its kind of hard to get to them as the vertical circuit board is soldered to the chassis.
