Just a white, lit up, blank screen with no audio.

First, I'd check to be sure the IF amp. tubes are good, and that they're connected in the socket, I think a bad or not lit up IF tube would cause that. As for the vid out tube socket, I've never had to change a tube socket on a circuit board before, but I'm sure someone here has. On one of my sets that uses circuit boards, some previous repair man had soldered a new socket ontop of the old one, to avoid damaging the board further, it doesn't look pretty, but it seems to work ok.
