WOOOOO!!! Fixed it!!

[TurboC--]

I fixed my WG4616.    (Of course I fixed it now that my new monitor shipped out today.)  I had broken one side of one trace on the XY daughterboard - a particularly slender trace which connects C359 to C358.  Found it while ohmmeter-testing all the traces that connected the caps I put in.  Soldered in a bypass wire (to the broken side), stuck it in the card, and after about 20 minutes of turning knobs (and almost coming here to ask for help) I got DOS displayed on the screen.    I still get some very minor and repetitive rolling down the side of the screen, but I can deal with that later. 

Unfortunately Puckman doesn't display correctly.  I don't know if it is something with the AdvMAME settings, or if I still have incorrect settings on my monitor somehow (which is maybe letting me sync to the mode DOS is using but not the mode AdvMAME is using?)  Guess I can mess with it more tomorrow.  AdvMenu also tells me it can't find any proper video modes, even though I set it up several times for Standard Arcade Monitor.  So I was using AdvMAME directly to launch the game.  If anyone has experience with setting up AdvMenu correctly for 19" Standard or wants to send me the modelines, let me know...

Sweet, I'll give it a shot, thanks. 

Separate question.  Here's an effective schematic of how the traces on the board are/were:

o---//o-----o

With o's as junctions and // indicating the broken trace.  The center junction was the one that broke the trace, so I thought it safer to not mess with the solder on that junction at all, but instead to wire the bypass like this:

o---//o-----o
\________/

It works, and those 3 junctions are supposed to be connected and thus (ideally) at the same electric potential at any point in time.  But later I was thinking about how the current loops would be, and technically I have altered the current flow through the trace.  I'm also getting a minor but consistent slow roll down the left edge of the monitor from top to bottom.  I have no idea of the cause, hopefully it isn't my bypass.  There's still plenty of knob tweaking I can try...

So why didn't you just connect the two parts, instead of going to the next one?

[TurboC--]

It's all on the same trace.  The center junction was already broken off from one trace.  I didn't want it broken off from the other one as well.  I doubt it is causing any problems, I need to mess with the horiz. osc coil and syncs again.

I downloaded the EasyMameCab CD ISO image and burned it.

from memory the easymamecab iso makes a self booting cd (shove it in your cd drive and switch on)

be aware though that it wants to re-format the hard drive of the machine you set it up on.

you shouldnt run into problems swapping between monitors while a computer is running
