D9500 problems and maybe found a swap-able TV tube?

I recently got a pair of D9500 monitors and have a few problems.

When testing with an atomiswave (Sports Shooting USA cart), the VGA connection's picture looks wrong on both of them AND "No signal" is on the screen. (VGA signal verified as good on a 25" tri-sync mak.)

When testing the CGA connection, I still get "No signal" but on monitor is all black and the other is all red (more on that one later).

The first picture show the built in VGA cable I was using. The VGA port on the chassis that I didn't use. The .156 header that I used for CGA. What did I do wrong?

Pictures 2/3 are of the VGA signal.

Pictures 4/5 are of the CGA signal. (It goes black/white.)

For reference these are the chassis/tube pictures of the first D9500 monitor that looks stock.

Note the neck looks like a 9+1 pin neck.

This is the second D9500 monitor. The tube and yoke look very different. Did someone tube swap this? Where/what is the D9500 part number on the yoke?

Note the neck is a 8+1 pin. The picture showing the neck board on the tube is as tight as the neck board will fit. It will NOT go on further. (Same with my B&K adapter.) The glass has a good will sticker of "Sanyo 6.95" on it. Was this a yoke swap or is there a Sanyo/D9500 compatible TV out there?

If you need more/other pictures to help me, let me know and I will post them.

Thanks for the tip. Any suggestions connecting for VGA/CGA?

All I have found are this:
http://forum.arcadecontrols.com/index.php?topic=90533.0
VGA: But from a PC, they has the same problem, but wrong resolution.

And this:
http://forums.arcade-museum.com/showthread.php?t=78574&page=2

But I don't have this "other" cable they speak of to switch to VGA.

I saw this on the BYOAC. Can anyone confirm this to be correct?

When using the supplied VGA cable:

**************************
**************************
**************************

1) Unplug the Monitor
2) Disconnect the approx. 1 foot long x 6-wire cord (and the round single wire) that connects from the mainboard to the small neck board.
3) Attach the 5-wire cable (from the provided VGA cable from Wells-Gardner) to the Large main board to the 5-pin slot that is just to the right of the power cable. More specifically, next to the two-blue wires.
4) Attach the remaining round single wire and the 6-wire cord to the Neck board from where you removed the cord from step #2.
5) Attach the opposite end of the VGA cord to your video card.
6) Plug in the power cord, boot up your computer and all should work fine.

Ensure your video resolution is set to 800x600 or less. If for some reason you forget, your monitor will say something like "Out of Range" and you will see a bunch of squigly lines. It doesn't seem to damage anything that I noticed. Just as a precaution I touched the wires from the provided cable and they were, thankfully, cool to the touch.

**************************
**************************
**************************

Again, you are actually disconnecting the ground and 6-wire cord from the neck board that connects the main PCB and plugging your supplied vga cable wires into the neck board. In addition, plugging the 5-wire cord into the main PCB.

Just seems a little odd...

And this from Ken:
http://forum.arcadecontrols.com/index.php?topic=61908.0

"I have found the "digital" monitors from Wells are 'particular' about how you hook up the sync. These monitors don't like having composite sync jumpered across horiz and vertical terminals as is common in most game cabinets. With these monitors composite sync is only to be fed to the negative horizontal sync terminal."

Which I have done both (jumper-ed/doesn't like and negative only)

I found a NOS D9500 chassis I had and I found NO "built-in VGA cable" but it did have a different cable.

I marked in the picture where the VGA cable plugs in. Does this little cable replace the VGA cable on the neck board and the single spot on the chassis is replaced with the other two spots on the chassis?

I also got a VGA to CGA adapter (common with the tri-sync maks) and put that on the VGA cable with a CGA signal. It worked as well as a VGA signal (it says "no signal" and it displays wavey/distorted in the background).

I believe I had mentioned that once in another thread. Now that I think about it I was suppose to get pictures as well, whoops.

I've got a couple of these monitors and they have the wiring differences you mention. I believe if you look in the manual or schematic you can see they are meant for different sources and there are jumpers for different source levels as well.

Can you link to this manual you speak of? I can't find one.

I can only find the 3 manuals listed on wells' websites:
Spec sheet
Schematics
Board layout with connections and controls

None of them list either the built-in VGA cable or this other connector I listed above. Or any "jumpers" to switch.

I otherwise played around with it this weekend.

With the "built-in" VGA cable, I wasn't able to get that to work for any signal. Including also trying a VGA cable to .156 pin adapter or using the .156 header on the chassis or the DSub.

I switched to the other cable that I had with my NOS chassis and I was able to get the CGA signal working using the chassis .156 header. The VGA atomiswave signal didn't work. Furthermore, after only maybe 20seconds of being on, the VGA cable heated up like I posted/asked about in this thread:
http://forums.arcade-museum.com/showthread.php?t=384930

Yikes!

I than tried JP Lost World (it outputs VGA and EGA) on the VGA cable and it worked correctly with no cable "heating" going on.

EGA is not yet tested.

So, maybe still an incorrectly set jumper for the VGA cable?

If someone has an actual user manual that talks about jumpers and cables, posting that would be great!

Just to be clear on a couple things,
1. There is no user manual that is going to hold our hands and walk us through every question and scenario. For example the jumpers and what they do are located in the schematic, bottom right side of page 2. Has a little table so that the user can figure out what signal level the PCB provides and what they need to do for this monitor.

2. We should be clear on VGA and CGA. Wells is really only concerned with connector type, pinout, and signal level. Not about the actual signal, ie you can input a CGA signal from a VGA card using the VGA connector if it is wired up correctly.


Do you have a part number on what you call the little cable?

I don't want to sound dense, but I don't see a table on the bottom right side of page 2.

This document right?
http://www.wellsgardner.com/pdf/Schematics/D9500.pdf

I see the 2 notes on the left side, nothing on the right other than "PD199500 MAIN BOARD" and the drawing above.

I don't have a part number for the cable, but it is pictured above (on blue carpet).

That's the right doc, you have to keep scrolling to the right. "PD199500 MAIN BOARD" is like in the middle of the page, there is still more of the PDF on the right side. The table is right above "PD199500 SYNC INPUT"

The monitor is definitely confusing some folks and the manual doesn't spell everything out like it does with some of the other digital monitors.


I was hoping the cable had a part number as I believe you need that cable when you are not using the VGA connector.
 
BTW, I said just emailed Wells to see if they could give me a part number and tell me when that cable should or shouldn't be used. Figured we should go to the source instead of BS'ing about it.

Guy responded saying he couldn't answer me due to system changes.
