Title: CRT VERTICAL ISSUE
Post by: ViciousKid on September 15, 2007, 10:30:36 am: Hi,

I currently have some arcade cabinets, two of the CRTs that came with it are having vertical screen issues, it looks like it is shrunk on the bottom of the screen and the picture goes off the screen on the top, so you can't see like your health etc. What can I do to fix this problem. I will get the model number soon and post it, it is a Phillips monitor

Thanks

This is the Good one no black bar at the bottom or crunched up...but just noticed it still needs to be moved down as u can see the health bar is a little off the screen..

There should be a remote board with 4-6 pots labeled BRT, CON, V-POS, V-SIZE, H-POS, H-SIZE

By the way, these controls may be on the main board, not on an extended user remote board.

Let us know how you make out.

Not on a K7500.

And you can see the control cable in one of those pictures. It's either that or the neckboard cable.
