Restoration question from beginner

[ffontana]

Hello All.
Just purchased an older black and white TV/radio/record player combo.
RCA TA169.
The guy I bought it from suggested it was working. He had it plugged in when I went to see.
The TV did not come on (radio and recorder player worked).
I did not want to pursue a restoration (by me or a shop) without knowing the picture tube is OK.

The tube does have a faint light on the back when powered on and there is a bright dot on the screen when power is shut off.

Is this an indication that the picture tube is OK?

Thank you,

Frank
