    Following on from my post HERE
    Just wondering if anybody familiar with these chassis may know how to get the image centered, the picture sits too far to the right with no way to adjust it, deflection issue?
    Look like its been this way since factory considering the burn sits to the right. I've turned the brightness up so the gap can easily be seen. I've managed to adjust the picture as far to the left as possible. It's not as bad in game like Pacman and Galaxian but far more noticeable when I hooked Berzerk up to it.
    I'm not overly worried about it but before I put it back in the machine I thought I'd ask.

      Have you played around with the centering jumpers on the chassis, near the pots ?
      Might help, but probably wont move the picture that far...
      [MENTION=286]Johns-Arcade[/MENTION] would be better for advice about it then me.

        Played with everything mate, It may not be easily fixable if at all. Only way to bring the picture to the edge of the screen is the h-sync but of course the picture loses sync.
        Go7's seem pretty basic.

            Like i said mate I've tried all the pots and jumpers. Those ones only moved the picture slightly left or right within the projected area, I need to move the projection to the left to fill that unused area. I don't think projection is the right terminology lol.
            Its like the beams need to be deflected more to the left to fill that dead spot.

              Have you tried to move the yoke a little closer ?

              Maybe get some tips off [MENTION=8377]dragonlee[/MENTION] and replace it with an LCD screen...

                No haven't tried touching the yoke yet, just wanted to get some feedback before blowing things up lol.

                This is what I think about his LCD's

                    I'm drunk and not reading well but if it's a convergence issue magnets can bring the image across. I used my kids fridge letter magnets to fix my Vectrex.
                    Winter is here and I'm still riding more than gaming, my current goal = 100,000 meters elevation gain for the year - well ahead so far

                      Hi Trav , Berzerk is a slightly different Sync output so it lock frequency will put it a bit more off center than most games , while it not important on a lot of games using the G07 you will need to Join the - H Sync and -V Sync together .

                      Basically you have a 6 pin input and 3 pin input connector on that chassis , The Red , Green , Blue and Gnd go in the 6 pin connector , the single neg comp Sync goes in the 3 pin connector on the V & H pins.
                      This will shift the picture across , on some games you only join the Sync to H pin ( like normal monitors ) in the 3 pin connector and will sit perfect or it can be to far the other way ( opposite to what you have ).

                        Spoke to Joey yesterday and reminded me to update the post.
                        The board is wired exactly the same as it is in the cab with both neg H & V sync tied together so unfortunately this is a no go.
