Hey everyone,

wanted to see if I can get a 2nd opinion on an issue i am having with my
CarnEvil cabinet I just obtained.

I cleaned the sensor and the focus lens in the front of the gun. When I try to Calibrating to gun. It shows the x on the screen but when I point it does not register on the screen

Any ideas ?
 
Videos are unavailable to me. (It switches to .com when I go to the link.)

What is your voltage AT the gun? What is your voltage AT the PCB?

Do both guns do the same thing?
 
On my Carnevil cab, I had to replace the monitor. Although my monitor was "pretty good"...I just could not get the gun to register. I even replaced the guns with brand new ones. Still I could not get the guns to register.

Then I replaced the monitor with one that had no burn in what so ever...then my guns worked fine.
 
Both guns doing the same and I ran the diagnostic test on the guns to see if pump and triggers worked, which thy do but when I point guns at screen says off screen, even when pointing directly at screen
 
what is the size of the monitor and is it worth fixing ?

I currently have my cabinet at a friends house.

Nope no sensors.
I think I put in a 25 inch monitor...cant remember exactly but it was a size bigger then the cabinet is intended for.
You also have to deal with an issue regarding this sync wire. You need
to connect the SYNC wire from the JAMMA connector to the monitor AND
the gun board......if I remember correctly.
My cab uses Happ Guns.
As far as if its worth it....I think it is.

I'm sure you tried turning up the flash brightness. another thing you can try is making the screen smaller and see if that helps, just for testing. I had mine like that and it only works with the flash brightness at 85 or better. I also have to turn up the contrast.my monitor was capped and a new flyback put in. didn't help. I also cleaned the monitor screen, gun lenses, and put new opto boards in the guns. didn't help. checked voltages ect.
 
The monitor is a standard resolution 25 inch. I replaced the one in my Carnevil with a K7000, going this route requires adding an isolation transformer. For your issue, first thing to try is new optical sensors in the guns. Both of mine were bad at first and it wasn't the typical broken wire on the optical emmiter. If your sure the guns are good, it could be monitor adjustments or a weak tube causing the issues.
 
the little gun board that plugs into the Seattle main board has a yellow wire, that's supposed to tap into the composite sync signal that goes to the monitor. if that's not connected, then the game board will not be able to mate to the monitor sync for the lightguns to operate correctly.

as such, I think there's a 6 pin breakout plug that goes between the JAMMA harness and the monitor signal plug, the sync wiring should have a yellow and white wire going into the plug, and a single white wire coming out running to the monitor. to verify this, use the diode test on your meter between the small plug to the gun board to the sync on the monitor. this could only be with games that came with Neotec monitors though, so maybe you'll have the yellow/white wiring to sync if it's a K7400 originally.

if you don't know how to crimp molex, you should learn, especially if that yellow wire broke off. :)

I also encourage reading the PSU guide in my signature. the lightguns should you get them to work again will be very erratic and inaccurate if the +5 is low to the main board. cleaning the JAMMA edge and adjusting your power supply to where you get 5.10V to the roms or at the red and black wires on the hard drive plug will sort that out.
 
Hey everyone.

so looks like after adjusting the Brightness higher on the monitor it fixed the issue.

so now the guns shoot and work.


another issue has presented itself now.

what can be done for the game to auto save this settings of the monitor / free play/ volume.

when I shutdown the game you have manually adjust these settings each time, also what can be done for the monitor to help the brightness issue? (Capkit ?)

As far as the pcb not holding the settings, it probably needs a new cmos battery. If your adjusting the brightness from the pcb which I'm not sure is an option, the battery would also fix that. However you should be able to adjust the brightness on the monitor chassis and that shouldn't change unless the chassis has issues like bad caps, bad pots or a bad flyback.
 
there's a brightness option in the test mode for the gun calibration. if I'm understanding right, that adjusts the actual brightness of the flash when you shoot. you can dabble with the brightness/screen adjustments on the monitor too though, turn the brightness up until you get pixel dots in a black background (the test mode is perfect for this) and then dial it back until the dots go away. you could also have a monitor that came with a garbage tube from the factory, if it's a Zenith tube of that era, chances are the guns are weakening.

if you pay attention when you turn the game on, you should see a yellow message on the boot screen that says something like FACTORY SETTINGS RESTORED. that will indeed imply that the CMOS battery is dead. it's a CR2325 lithium battery, towards the middle-right of the board.

it might take a few power cycles for it to grab and keep settings, I had some difficulty with the one at work. eventually I got a green GOOD message out of it. ^_^

He is sayin he does not have the original sawed off shotguns and had to add a synch wire.

Raising the brightness and contrast will make the light guns work more accurate.
also adjusting the focus on the flyback.

You can buy a 2032 coin cell battery and throw it in as a replacement and it
will save the settings.
 
Old thread, but I thought I would throw in my experience since I just fixed this game today (new purchase). It would not register shots at all. Properly adjusted flyback settings and screen geometry. Set "flash brightness" in menu back to factory settings. Game works fine again.
