Just installed a jrok board in my Stargate cab with a Samsung A48KRD82X02 monitor. The image quality is fine, but shifted too far left. Maxing the horiz position pot inside the coin door doesn't center it. (The left red border on Robotron is still just offscreen, for example.)

Are there any other adjustments to make (perhaps on the main monitor board itself)? Thx!
 
The monitor number you listed looks like a tube number. What chassis is in the machine? Most chassis have a horizontal position jumper that can be moved around.
 
That ws the tube number. Sorry! The 2 numbers I found on the monitor board (on stickers) are WG 8051254, and 025A1482-001F. I did find a small horizontal osc pot on the near left corner of the monitor board (viewed from the rear of the cab) and it just brought the image onscreen when fully turned. But this has both that pot and the horiz position pot all the way over. A jumper tho shif the horizontal position might be just the trick.

Let me know if the numbers I gave you above are not correct. (I'm more of a pinball guy by trade, and relatively clueless about monitors etc.!) Thx.
 
Thx. I'll check for future reference, but it seems that the problem is solved! I looked and didn't find a jumper, but there was a 2-position pushbutton switch on the left of the board (labeled 'sw 301'). Pushing this in to the 2nd position shifted the image right, and I was then able to center it properly with the 2 pots. Picture is fine now! Thanks for the responses and getting me to look in the right direction.

Update: After going a bit cross-eyed looking at the monitor board images, I found that mine is a WG K7300. Good to know for future reference. Thanks again!
