Fix or ditch my arcade monitor ?
TPB:
Hi guys,
I have a Street Fighter Zero 2 cabinet (aka Street Fighter Alpha 2).
When you power it up, it used to take about 40 minutes before the picture became viewable (I presume once the tube had warmed up). After that, if you powered it off & straight back on again, the picture instantly appeared, as the tube was still warm.
But that was before. It now seems to have got worse. The last time I powered it up, alas, still no viewable picture after 40 minutes.
EDIT: Here's the monitor in action ... a jumbled multi-colour mess of lines :
The monitor is a Videocolor A59EAS13X25. The monitor chassis is a Glendale GE-728HR, with a testing certification dated June 26, 1992. Please take a gander at the photos attached.
I know nothing about the guts of these monitors. Perhaps it just needs something simple like a "horizontal hold" adjustment. But I can't see any knobs for horizontal or vertical hold.
Adjustment knobs that are visible :
The monitor has three knobs for R-BKG, G-BKG, and B-BKG. The monitor chassis has three knobs for R.GAIN, G.GAIN, and B.GAIN ... it also has knobs for B.ADJ, and PIN.CUSH ... it has a screw adjustment for U.LINE.
Guys, is it fixable ? ??? ???
Second question ... can this monitor be connected to a J-PAC ?

A few extra pics of the monitor chassis :
Malenko:
looks like a Vsync issue.
As for JPAC, yeah, since CPS2 is jamma, you can unplug the jamma harness and plug the JPAC in. YYou'll hafta wire up the kick buttons to the jpac instead of using the CPS2 kick harness.
boardjunkie:
Nope....thats a H sync problem. Try adjusting the H hold and see if that brings it into proper operation.
Kevin Mullins:
Definitely a loss of Sync..... first thing I would do is re-seat the video input connector and check for bad solder joints on those header pins for that connector.
BTW - that is a re-branded Wei-Ya chassis. (728HR)
Glendale/Eygo/Promax, etc, etc are all the same, they are just the name they were sold under.
