It's usually the fly back transformer that goes and "if" you can still get them for that model having someone fix it would cost roughly $200
On the 1960 monitors it was almost always a bad solder joint that fails on the back of the high voltage sender on the tube. That monitor suffered from really bad cold solders all over the circuit board.
i have a 1960 i got from a guy who ran it so long the power transistor around the middle of the board literally burned a 1/4" hole thru the board, when i went to take the transistor out it crumbled to powder and all that was left were the leads.. i did fix the monitor however. Turns out he was smacking the thing to make it work for years when all it would of took was resolder the transistor.
