No, different monitor. Bought it seperate. Still wondering about the vertical sync wire and caps.

AlanS17 · « **Reply #41 on:** July 01, 2005, 10:58:17 am »

It sounds like the cab was originally wired for a monitor with a composite sync and you've got one with seperate syncs. If you've already tried tuning the vsync adjustment and it didn't help then try this.

Take the wire that you've got going into the horizontal sync, split it, and send the second wire branching off of it into the vertical sync.

Even after you do this, it might still roll, but at least you should be able to properly tune it with the vsync adjustment now.

Blacksmith · « **Reply #42 on:** July 01, 2005, 04:39:21 pm »

Or could I add a vertical sync wire to the chasis pinout and run it back to the vert sync on the jamma harness. (I'm assuming that there is a v-sync on the harness, but will have to check.)

AlanS17 · « **Reply #43 on:** July 01, 2005, 04:55:23 pm »

The JAMMA harness only supplies composite sync. It doesn't supply seperate hsync and vsync.

Blacksmith · « **Reply #44 on:** July 01, 2005, 05:50:03 pm »

after further investigation, I believe that the wire on the chasis board was connected to the horizontal sync pin ( I think). It is very difficult to distinguish on the picture of the pin layout on the bottom of the chasis. Anyway, I moved the wire over to what I think is the v-sync pin on the chasis and the monitor's picture didn't change that I could see. My biggest problems right now are that the picture still rolls pretty bad and I have the thin white or grey lines going from left to right across the monitor. I'm not sure what this is, but could those lines be caused by "refresh rate?"

AlanS17 · « **Reply #45 on:** July 01, 2005, 05:58:07 pm »

You need sync signal going into both the horizontal and vertical syncs. Split the sync wire and send it into both hsync and vsync. Give that a shot.

I don't know what the lines across your screen are yet, but let's get a stable picture first and then worry about what it looks like.

Blacksmith · « **Reply #46 on:** July 04, 2005, 01:00:37 am »

Here is the update: No good news yet. I spliced the sync wires into two separate wires and ran them to the monitor and j-pac with no apparent change in picture. Picture still rolls horribly and when I try to adjust the rolling the adjustment pot (I think thats what it is?) is so touch that I just can't seem to get it to stop. Could the adjustment pot be bad too? Anyway, picture is still kind of faded looking if you can see it in my pic and I still have the white/grey horizontal lines running across the monitor. The second pic is of the back of the monitor itself. I have six adjustment screws on the end of the picture tube, but am unable to read what they adjust as the board must have all of that info on the other side. Does anyone know what these adjust and what order the are in from left to right. I don't really care to start turning them and mess anything up and I am also a little intimidated by the DANGER High voltage tag right underneath them! Hope somebody can talk me through this. This sure is frustrating!

Ok, see that large bundle of wires going down into your cab?
(The ones that are soldered to the board, not the rgb input wires)

Follow that and you will find your remote adjustment board.

(Do not power on the monitor with that board disconnected, it can damage the monitor)

This is a small board with (Usually) 6 pots on it that have most of the monitors adjustments.

DO NOT adjust the pots on the neck board, as they control the color balance.

The manual for your monitor is here I think. (It looks like a 7000 series.)

http://www.mikesarcade.com/arcade/manuals/monitor/WG-K7000.zip

There are no harmful voltages on the remote adjustment board, but plenty on the main monitor board.

p.s.

Happy 4th!

I have been using the remote board to try and stabilize the rolling that I've been experiencing with the vertical hold pot. I have been unsuccessful trying to get the rolling stopped. The adjustment pot for the vertical hold seems extremely sensitive to the touch and does allow me to slow down the rolling at times, but it won't completely stop it and if you just touch the adjustment pot it really starts rolling. Do these things go bad? Nobody posting has been able to give me the right answer for this problem yet. Also, the horizontal white/grey lines are still a problem as well as the screen colors look washed out or faded. Can I adjust the colors with the adjustment screws on the back of the monitor shown in the pic? Also, do I do this with my hand or a small screwdriver? I don't want to get zapped!

Here is another question for you:
I have two LED display lights on my J-pac that indicate sync function and neither one of them are lit. Does that mean anything regarding all of the problems that I'm having and what do I do to resolve it?

dabone · « **Reply #50 on:** July 04, 2005, 04:42:15 pm »

Just looked at my cab with jpac and I have 2 leds lit.

So that probally means you aren't getting correct signal to the monitor.

Do you have a dos boot floppy to try?

If you are running a arcadevga card just grab a dos boot off of

http://www.bootdisk.com

Then if everything is working right you should be able to get a dos prompt on the arcade monitor. (This is to check if your card is working correctly, ruling out any windows driver issues.)

dabone,
I have no idea what you just told me to do??? Yes, I am running arcadevga card in my pc. What is this dos boot that I'm supposed to download and what am I supposed to do with it? I just don't know what you are talking about. How is this supposed to get the led's to light up on the j-pac?

dabone · « **Reply #52 on:** July 04, 2005, 05:35:37 pm »

Dos boot is loading msdos from a floppy disk.

Goto bootdisk.com and grab a boot image, run it with a blank floppy and it will create a bootable floppy disk.

If the arcadevga is working correctly, then you will get a a:> after you boot the floppy.

Just curious, you do have the keyboard cable plugged in to your jpac?

(The jpac draws power from the ps2 connector)

Error for the jpac from the ultimarc website.

Error Conditions:

LED never lights:
Board faulty, cable faulty, PC not powering up correctly.

LED gives two short flashes and the I-PAC is connected via USB:
The board has mis-detected a PS/2 interface. Check USB controller is enabled and working on the PC. Try another USB device as a test.

LED gives one short flash then stays off:
I-PAC has detected a USB controller but the PC is not detecting the device as having been connected. Check USB drivers on PC.

LED flashes 3 or more times after initially lighting:
Switch test failed. Check chart below for failing input. Check switch wiring. Try disconnecting this wire and see if the flash pattern changes.
LED lights as soon as power is applied, never flashes but just stays on constantly:
See the first line of the table below

maybe I have this stuff hooked up wrong? I just had the keyboard connected to the pc because it isn't inside the cab yet so I just left it hooked up that way. I dissconnected it from the pc and hooked it up to the j-pac and fired it up that way. Didn't get any illuminations from either led. I'm kind of confused about this hook up I guess. I thought that the j-pac was getting power somehow from the monitor cable that is connected to it? Guess thats wrong.

Blacksmith · « **Reply #54 on:** July 04, 2005, 11:02:19 pm »

To all that have stuck with me thusfar, thanks. My stupidity has no bounds it seems! Well, I now have a stable picture for the most part. Turns out, in my blindness, I never hooked up the cable from the j-pac to the pc as dbone instructed, so I was never getting power to the j-pac to handle the sync issue. After doing so, the picture stabilized immediately and my seizures stopped! I was able to adjust the color too. Here are the new problems:
when the screen changes from desktop to mame games the vertical roll starts immediately until I stop it with the adjustment knob. (this will suck during game playing I'm sure) I think it has something to do with resolutions? What do I do for that?
Next problem is vertical and horizontal height and width don't look right. If I adjust it so I can see the whole picture on the screen I have to make it much smaller than the bezel. Doesn't seem right?
Another problem is when I go to my itunes program the screen changes to a yellowish color. Very weird.
Any thoughts on the newest probs?

Along with my other questions regarding my monitor, can someone please put into terms I can understand what exactly the ATI Control panel does in the ArcadeVGA card utility program? I did not install it and am wondering if it could be the answer to the rest of my monitor issues?

AlanS17 · « **Reply #56 on:** July 05, 2005, 02:48:02 pm »

No power? Yup, that would do it.

I could give you pointers from here, but most of them would be for regular video cards. I've never actually used the ArcadeVGA so I can't answer alot questions specific to it. I'll continue to watch the thread and help where I can, though. Good luck.

dabone · « **Reply #57 on:** July 05, 2005, 03:26:21 pm »

Ok, this monitor is NOT going to look at good as your 9200.

Usually you will lose a little bit around the edges.

Not sure about the itunes, thats not usually an app you run on a cab.

To fix the rolling problems after game launch use this utility

http://mamewah.mameworld.net/downloads/mame_res_tool.zip

and remove all non 60hz modes.

Then generate your ini files.

Blacksmith · « **Reply #58 on:** July 05, 2005, 03:34:47 pm »

I'm using emuloader, not mamewah. Will that resolution tool work?

dabone · « **Reply #59 on:** July 05, 2005, 04:10:03 pm »

The res tool is for mame. It has nothing to do with mamewah.

Blacksmith · « **Reply #60 on:** July 05, 2005, 05:47:45 pm »

I'm not sure how to generate the ini files for the resolution tool. I've got the ATI control panel loaded on the pc and the resolution tool program as well. Can you walk me through it?

dabone · « **Reply #61 on:** July 05, 2005, 07:49:59 pm »

Post a request over here.

http://www.mameworld.info/ubbthreads/postlist.php?Cat=&Board=arcadeospc2jamma

it's Mamewah's support board.

(He also answers questions about the res tool also)

Blacksmith · « **Reply #62 on:** July 06, 2005, 03:27:37 pm »

Talking to a friend of mine he thinks that maybe the monitor will not really support a great looking screen during desktop mode or itunes screen and maybe thats why the screen looks a little blurry and turns yellow? Is there another music program that I could use on the mame machine that might run at a lower resolution? Have to be easy to set up! Something that resembles a juke possibly?

AlanS17 · « **Reply #63 on:** July 06, 2005, 04:34:03 pm »

Alot of the programs mentioned in the Audio/Jukebox/MP3 forums will suit your needs. Try googling a particular one called Arcade Jukebox, though. It's very basic, but works well.

Blacksmith · « **Reply #64 on:** July 06, 2005, 04:35:37 pm »

just downloaded it and am trying it out.

dax · « **Reply #65 on:** December 22, 2005, 02:49:21 am »

I have this same monitor in a Neo Geo cab. I was able to get it working, but I have similar resolution issues and I'm not sure how to handle it.

One issue is that I can run the monitor at 800x600 and it looks pretty decent, but the bottom part of the screen is pinched and the vertical sizing knob doesn't turn enough to compress the screen to completely be displayable... for example in windows, I don't see the task bar. I'm not sure how to fix this. I can run at 640x480 but this seems to create more problems in mame.
