Sega Rally Twin Monitors out of sync
Chassis seems to be: MS9-29A on both cabinets.
I cannot find any adjustment for H-Sync or V-Sync from this chassis. The Pins were set to 24khz and the monitors were working properly but after moving the H-Sync or V-Sync is a bit ***ed.
I adjusted this kind of problem np in my other monitors in the past but with this one I cannot find the adjuster pots
Pictures:

There seems to be some glue in the H-H 15khz and H-H 24khz screws I don't know if these are the right ones.
Thanks a lot for help.

The H.H pots are horizontal hold, give the 24k one a go if it's a 24k game.

Re: Sega Rally Twin Monitors out of sync
It's in the both monitors exactly the same, maybe some GND problem?

Re: Sega Rally Twin Monitors out of sync
Be a massive coincidence to cause exactly the same problem on both monitors, gotta be something that affects both surely?

Re: Sega Rally Twin Monitors out of sync
Or is this after you have adjusted the same thing on both? Or are pics from before you touched them or after?

I didn't touch either of them. TV repair man is coming today to check it out. I hope he can figure out what is causing the problem.

Re: Sega Rally Twin Monitors out of sync
Yeah it's strange it affects both, cabs are only connected by the link cables aren't they? Separate psu's and that?

TV guy said there is probably something distorting the video signal and there is other more expert guy coming on wednesday to see with an oscillator.
