Space invaders deluxe- thin scrambled line in middle of screen

Hi, I recently purchased my first arcade machine, space invaders deluxe. The machine lights up when powered on. The screen, when warmed up, just shows an inch wide vertical line of scrambled nothingness. I'm new to repairing games so I don't know if its a power supply problem, a rom problem, or a monitor problem. Any advice would be appriciated. Thanks!

Edit: I tried coining it up to see if it was running blind but didn't hear the game start but I'm not so sure the coin mechanical works because it looks like the previous owner modified it with a button.
Edit 2: I removed the roms to test to see if they were the issue but all that did was make the vertical line wider.

make sure the yoke is connected right. the wires are all removable. I unfortunately don't know what goes where off hand.

mine has a Wells-Gardner V1001 I think it's called.

I don't have much experience at all with SID so maybe it's something board related. also pay mention that your power supply board (on the left of the cab, facing the back) might need work done to it, I don't know any of the test points for voltage though.
 
I'm no expert but it sounds like the display may just be squashed? Has it ever been recapped? Have you tried any of the adjustments?

btw...don't electrocute yourself! A lot of voltage is in those monitors, even when OFF!
