Arcade VGA Blues

[Warmachine]

Hey,

I bought an x men acade cabinet that still had the monitor and jamma harness for a few bucks. I then purchased the arcade vga card and jpac to have a hassle free hook up. But i am getting nothing but a blue picture on the monitor both led on the jpac lights up which signals a good signal going to jpac from the arcade vga card....I am lost, could it be a bad jamma harness, is there any way to get some kinda signal to the monitor to make sure it even works, i guess this is the noob post of the day.

Thanks Sean

ok..very noobish of me i dont know whant kind of monitor it is.
Hopefully i can get some info without the need to know that, if not i will check when i get home.

I'd check for some kind of signal @ the end of each color wire.... Deffinitly check the continuity of each video wire in the jamma harness.... If it was a used harnedd there is no telling who converted it. ther e ma be losse wires. I have a street fighter two that had garbled sound... fixed it buy insulating the 2 speaker wire on the jamma harness that had been left bare and were touching each other. sooooooo

Thanks for the info, i checked the monitor it has a sticker close to that dredded red cable that i fear more than monday rush hour traffic.
Only two sequence stand out.  G-A63ADG25X, and 04RC0105-009 i am not sure which if any is the model #. I ordered a new jamma harness if figure if i can spend money on a j-pac and vga card 15 bucks is not gonna kill me for a harness plus this one looks busted with electrical tame and empty connectors. I know some kinda signal is going to the monitor since once i turn on the cpu and it turns blue with these wavey lines when i turn the v hold knobs i see some kinda movement but no pic.

Windows XP is trying to use the Stock ATI Driver!

Try rebooting in safe mode, and install the ArcadeVGA drivers and reboot.

[Warmachine]

I will try that, but i am not running xp.

I finally got a picture up after the clip that holds the v-hold contrast and so on fell, but my pic is kinda fuzzy with these solid horizontal ines going accross the screen and the colors dont look so sharp is this a sign of bad caps, also what exactly are thos 6 white knobs on the neck, can i do any tweaking with them.

You may have loose connections.  I had horizontal bars across one of my monitors, and after I took off the (damn memory is failing me tonight, it's the circuit board on the back of the yoke) and reseating it, I had a bright crisp picture.  Check for loose connections.

[Warmachine]

ok due to my voltage phobia and that nightmare giving glow at the back of the yolk how should i approach this

[Warmachine]

oh one more thing what are those six white knobs for is safe to touch them that glow really makes me nervous to go back there

[SirPeale]

Get over your nervousness.  Be carefull and you should be okay.

You can use the adjustment knobs while the machine is on with no worries, in fact that is why they are there.  Avoid touching the obvious (the board itself) and you'll be fine.

As for reseating that board, turn the machine off and pull it straight off (at least that's what I did with mine.)  Then plug it back in.  Be careful, not for shocks, but to make sure you put it on straight.

[Warmachine]

Thanks for the info, removed the board twice, i also hooked a new jamma harness i bought same thing, there is also a faded green color run at the top right...is that sign of a needed cap kit...i hope not.

[SirPeale]

Can you take a picture?  Sounds almost like you have a speaker thats' too close to the monitor.

Hey Warmachine, did you ever solve this problem?  I am having this exact same problem now.  I tried to get a picture of it, but none of the 6 I took came out well enough to see what the problem is.
