Donkey Kong Monitor Issue?

[CTpunk]

Think I should have put this here instead of the resto section...

Hey there brand new to this and have a few questions regarding a Donkey Kong machine I just picked up rather cheap. Dont know what generation this is but its got the blue sides and has a Sanyo monitor. Ive gotten some useful info from researching around here and elsewhere but havent found the exact problem yet. The game fires up and plays, guy runs and jumps and dies but Ive got no real screen (see pic). Its seemed to collapse into one center vertical line. I havent done anything except cleaned out the layer of dust on everything, inside and out. Does this look like a "cap kit" repair? Also if it is a cap kit issue how many caps are we talking about here? Replacing them all on each and every board? Seems like there are over 100 no? Thanks for any help and please ask me to include any info that I may have left out.

IF the monitor is mounted on it's side , then it is loss of vert .

IF a standard mount, there is a faulty connection in horiz sweep.
 there will likely be a burnt spot around the faulty connection. thus helping u in locating fault.
remove carbon track and resolder connection  ( assuming little to minor pcb damage)

Hard to tell from those pics, but yes it's vertically mounted and thus has vertical collapse.
(and it's a vertical game)
Looks to be a typical Sanyo 20EZ.

Do yourself a favor and order the deluxe kit from Bob Roberts as it's probably never been touched before from the looks of it.

And there is a bunch, but not nearly 100.

A cap kit may seem daunting, but once you start doing it and you get into a rhythm it goes pretty fast.

There's also a "service switch" in the center of the monitor's main board that if flipped (it has a tiny lever style handle) the wrong direction is intended to shut off the vertical deflection. It could easily be flipped if you were cleaning the board.

One direction shuts off vertical deflection and the other direction is for normal operation.

It's also possible that enough of the electrolytic capacitors have gone bad to kill the vertical deflection. Replacing the capacitors should bring it back.
