I just picked up a cabinet from Teckkev, with a Wells Gardner 19K4906 monitor in it. Everything seems to be great, except the monitor is cut off on the rightmost half-inch.

Does anyone have an idea what could cause this? If needed, I can throw some pictures on Photobucket and show them here.

Is that a cable that looks to be about a 16-gauge wire, with a round connector on the end, that'd attach to one of three prongs on the board near the back of the monitor?
 
Yes. There is one for vertical shift and one for horizontal shift.

Also, you may be able to adjust the position a little by adjusting your horizontal hold a bit, but if you go too far, your picture may start rolling (especially if it hasn't been rebuilt lately)...
 
Have you tried moving the horizontal shift jumper?
Done. This seems to be called "Horizontal Raster Control" on my monitor - is that possible? It didn't seem to really affect things at all, though, no matter what position it was in....

Yes. There is one for vertical shift and one for horizontal shift.

Using the Horizontal Hold, I actually managed to get 90% of what was missing back on screen! Thank you for all of your help!

If you have any further suggestions to get that last 10%, or why my horizontal raster shift may not be moving the picture, please let me know.

For the record, Cab was gutted for Dptwiz, but he already had the cab to program into his CNC. Colin ask if I can have it ready in 2 hours. I wired cab, installed monitor (from working complete game), and tested controls, coin, etc. I stated I would had it properly built if he would have picked it up the next day :)

I know Colin is not making any accusation. I just want others to know I did not throw crap together and call it a game, lol. :)

Yeah, Kevin took great care of me, especially on such short notice! I have to work the next several days, otherwise I would've waited. Also, Kevin didn't contact me with a "game for sale." Instead, I actually bought three separate pieces - a cabinet with a wiring harness and power supply, a monitor, and a motherboard. Kevin was nice enough to put everything together so I could test it all out before throwing it in the van.

I don't even see this as any sort of difficulty with the game - It's just a good way for me to get familiar with things that I didn't know before. My experience with monitors before this was limited to removal, reinstallation, and vert and hori hold and shift. Never had to deal with a raster shift before.

Overall, though, I feel like I've accomplished quite a bit by getting the picture 90% of the way to perfect, and rotated, and whatnot. Just want to see if I can get things perfected. Anyone here able to give me a rundown of how to properly go about a raster shift?
 
You accomplished more than me on monitors :) My 1st and only image flip attempt was an epic failure. I got confused and flipped both of the 2 pin connectors (after I split the 4pin in 1/2). That monitor still sitting in the megatouch :)

Oh, I actually DID have to flip both of the 2-pin connectors after cutting the 4-pin in half... it was rotated 180 degrees instead of just upside down. It took a couple tries to get it right, though.

Feels like things are coming together nicely, though... I may pick up some more games soon. Blitz is awesome, but I've always wanted a Sega STV setup for Die Hard Arcade, the couple Virtua Fighter games on it, and maybe Terra Diver.
 
if you can't get the image to shift with the raster pins, then you should probably recap it first.

other than that, you can decrease the horizontal size slightly with the horizontal width coil to get the rest of that picture on the screen, but it'll make the black part on the other side a little bigger.

And you can change a ceramic cap on the chassis to decrease the horizontal size limit, too, with the same qualifier as above...
 
check the yoke hasnt shifted putting the image too far off to the side. sometimes the little rubber wedges fall off and the yoke shifts one way or the other.
