Ms. Pac Man Monitor Issues, Just cap'ed but still need help

I cannot seem to get this Ms. Pacman monitor right.

First off can anyone tell what kind of monitor it is?

I mean I suppose it should be an Electrohome GO7 but I cant seem to find anything that indicates that.

I just cap'ed the monitor today. I changed every capacitor except for these two. The really big one on the left and the big one that lays sidways on the right. I'm not really sure what it is or how it works. How does that adjust something?

One other thing is that according to this little paper on the right, the horizontal sizing is this coil type thing or whatever this is on the left.

This is what I'm getting. I can't seem to dial it in. This is about as good as I can get it. It's still a bit wavy, scrolls slowly from side to side and and off center.

Thanks. This is driving me nuts.
 
Yes it is a 4600.

And whether you are testing it using an original Ms. Pac Man or a Multicade board, the problem is your sync connections. Both of those games use composite negative sync. You have the sync connected to the positive sync pins on the left daughtercard. Move them to the negative sync pins and you should be able to adjust it to a good picture...
 
Hmm I'm not quite following. Ok touch up the solder points I get. Move the sync from positive to negative; is that one of the connectors? Do I need to move the location of one of the wire connectors? Thanks again for your help!

Also my bad I forgot about the monitor section.
 
Your first post - first picture is what Mod is speaking of.
You are using a game requiring negative sync which you currently have wired for positive sync.

Page 18 - change your connector from positive sync to negative (connect the white wire to N horizontal and yellow wire to N vertical sync)

That is exactly right. Typical good catch by Riptor. If you can wiggle the x.y cards and the pic does not change, you dont need to worry about them.
 
It doesnt look like it has the card he needs with the separate header for sync.

I didn't see the pins either, but the solder spots are there on the back side, so I thought he just didn't take the picture from the proper angle...
 
That did it!!!

I moved the white and yellow down to the negative sync and now the screen is perfect. Thank you guys so much, I would have NEVER figured that out on my own.
