OK,I installed a Lizard Lick 60in1 and Lizard Lick power supply/adapter replaced the fuse blocks,replaced the edge connector ,cap kit and had someone I know make adjustments(pots,H+V,etc )and when he was done the picture looked awesome and the play was fine but we couldnt shake 2 small issues; a slight "flag wave" on the right side of the screen and the picture is slightly turned to the left(Left is too low..see pics)It was really late and we ran out of time to keep going,but had to quit..Hes coming back tomorrow night to help out again,do you guys have any suggestions?Thank you!!! Jeff (Pacs show the worst)the pics below;

If this is the worst it gets with a GO7, then you should be happy. These monitors do not do real well with the 60 in 1 and multi-game stuff out there and it has nothing to do with the monitor. Decrease the vertical size a bit and enjoy it for what it is. If the image is overall crooked, loosen up the thumb screw on the yoke and give it a twist while your buddy watches.

My g07 did the same thing with the 60/1 I swapped the chassis with another g07 and it wasn't noticeable. But the image is centered put about a quarter to far to one side I moved the centering pin and it got better but not quite perfect.
Thanks elutz for the advise on swapping chassis I would've never tried that.

Just for the record, this type of problem is NOT limited to the 60-in-1. I've seen G07's have this type of warp with a regular Pac-Man board. The multi just seems to enhance it.

You can help fix it a little by changing the values of C517 and C518. They are normally a 100uf 16v and 220uf 16v cap. You can change both to a 220uf 16v cap, which will result in a little more square of a picture.. I've seen chassis with some of these caps increased to 1000uf 16v and still work, but it's not really recommended. That section has to do with the keystoning and pincushioning, so changing the values some isn't that critical.

There's also a transformer right near there by the flyback that sometimes gets cold solder on the pins, and can affect it a little.

And you might find you can do a bunch of changes and nothing gets better...
