Hey guys -
So I got the Playchoice 10 home today. It needs some work, though is playable somewhat.

The first thing I want to tackle ASAP, is the upper monitor. I don't know what this phenomenon is called, so I couldn't search for it. But, after the monitor warms up, it does this:

Despite the picture, it is NOT rolling - the black scanlines (between the data top and bottom of the image) are fixed. You can see the characters change as controls are used.
When it's NOT doing that - i.e. right after turning the game on - it's compressed vertically, and the V-SIZE knob won't turn any more to make it taller.

I have not tried the H-Hold pot yet (didn't have my manual handy when I was inspecting the monitor, didn't know where it was. I'll try that later tonight..)

Other than my game having an ultra-low serial number, I know nothing of any work done on the game before I picked it up today.

Anything to check for this? Recapping?

that kind of looks like a yoke issue if that won't adjust out.
 
that looks like bad caps and adjusting your H-Hold.

bring it with you when you come by next.
we can look at you when you pick up your other stuff.

Peace

Thanks guys. I'll see if I can at least keep the display *visible* today, before guests come over for the game. Their kids (..and some of them I'm sure) would like to play SMB on an arcade. :D

Looks like I may be down your way in a month or so, if that's too far out, I can make a special trip. :)
