I am done with my Blitz 99 to golden tee for 2005 conversion, however I cannot figure out the sync issue. I am getting a scrambled picture on the screen. I have the red green blue and ground hooked up to the correct pins on the chassis. However when hooking up to composite sync or any of the other pins left I'm getting a scrambled picture. I have switched all the dip switches to try medium and standard resolutions. The wells gardner medium resolution monitor is out of a Blitz 99 so I know it works since I tested it out today. Any help would be great. Anyone having any pictures of the video hookup on the chassis would help also.

You may also have to adjust the Horiz Freq or 50/60Hz or something to that effect on the main chassis. Without knowing exactly which monitor you have it's kinda hard to point out.
Connect your sync to composite negative and go from there.

I have no idea what that is .... should be something like a 25K7500, 25K8000 or U5000, etc.
Can you find the "P" number on the main chassis? (like P738, P790, etc)

P793
thanks for your help

WGM2575=Wells Gardner 25" k7500. If you are sure your sync wires are connected correctly, try adjusting the horizontal hold which, iirc, is located close to the transistor that is mounted on the monitor frame.

I have the sync connected to the last pin. There are red green blue horz sync and vertical comp sync. I do not have anything on these sync pins

Sarge is right, it's a 7500 series.
Sounds like you have the sync connected correctly, so try the horizontal hold adjustment.
Which is kinda hiding way up towards the front of the main chassis.
