Does anybody have any suggestions on how to fix this?

I was playing Ms Pacman when somebody turned on another tv when suddenly the Ms Pacman arcade started to play blind.

I used the G07 flowchart and checked F901 and F902 and both are fine.
The diodes on D901-D904 are also fine.
The Resistor on R101 is also fine at 220
From what I can tell I think the flyback is okay. There is no visible cracks.
Maybe I'm testing the hot incorrectly but when I tested the HOT using the DMM by placing two needles on the two legs I get a reading of 0.
When I place one needle on the outer casing of the HOT and the other on the leg I get a reading of 510.
Is this correct? I thought it should be a reading greater than 10 when placing the needles on the two legs and 0 when placing one leg on the outer casing and one on the leg of the HOT?

I thought the HOT was shorted and replaced it with a new one but I got the same reading with the DMM?

Am I testing it incorrectly? This is all new to me so any help suggestions or help is appreciated.

Thanks.
 
By the way there is no glow on the neck either.

Thanks for any help given.
