Taito Egret 3 Vertical size issue

[kebrank]

I just bought an Egret 3 and I'm having problems displaying some PCBs.
It seems the vertical size pot can't reduce the screen size enough to fit in the monitor visible area.
For some of the games i have to choose between see the score on the top or the life bar on the bottom.
Does anybody have any idea if this can be fixed?

Thank you,

Probably the VR7 'v.sub size' pot on the chassis.

I'll try it tonight. I hope it works.

Thank you,

I was able to reduce the image a little bit more using the VR7 pot but it's still unacceptable.
It's not even close to fit the whole image in the screen area .
Any other suggestions?. Any other people with Egret 3/AWSD around that had the same problem?

Has your tube been swapped because the only time I had a v.size that was still out and not adjustable by either v.size pot, the tube had been replaced and didn't exactly match the chassis.

I guess you could try checking the B+ pot values with a multimeter but its not the most fun thing to do.

Try asking over at arcadeotaku you might get more help over there.

The tube is a Samsung and the chassis a Wei Ya.
The monitor also has some geometry issues but that's another story.
I'll try at arcadeotaku later today.

Thank you,

Yeah, good old samsung / wei-ya combo. I have the same.

The geometry issues are near-inescapable sadly, especially in 15K.

You might have a bit of luck with an answer for the v.size though.
