Hi,

I don't know if this should be posted in this section or the monitor section but I am hoping that someone with the information please comes forward as this problem is driving me crazy!

This is an ongoing issue over the years and I have searched the forums and the internet countless times and cannot come up with a definitive answer to this problem.

I have had several Big Buck Hunters over the years, Pro, Safari and World and the problem effects all versions of the game.

The problem is the gun calibration specifically the Gun Tracking or The Signal Strength which depending on the display dies out to zero before reaching the edge of the display.

On some displays the sight works great all the way to the left, right and up but try to shoot something at the bottom 20% of the display and the gun does not register.

On other displays the sighting works great up and down but try to shoot something at the left or right edges and nothing.....

I have tried resolving this by swapping computers, I/O PCB's, new optics in the shotguns, rebuilding the chassis and even rejuvenation of the CRT even though the emissions were in the green and nothing helps.

The information I have come across is basically the same, "those Makvision displays are crap" but that does not explain why this is especially as when I put a test pattern on the display it is vibrant and detailed.

From what I understand the guns "look" for the scan lines and that determines where the gun fires at a given point in time. Using this I would have to assume that somehow the display is not producing the required scan line strength -- but to the naked eye, the display is working correctly and looks good.

Just for demonstration purposes I uploaded a video of the situation I am trying to resolve. This is a game with a rebuilt chassis, rejuvenated CRT, rebuilt computer and new optics in the shotguns:


This display is worse than the one I just swapped as the guns fail sooner that the previous one that shot great top, left and right but bottom no good.

This issue changes (better or worse) when I swap displays so the issue is with the displays and not the cabinet (components).

Does anyone know what component(s) on the display cause this very very frustrating situation and / or has anyone resolved this in some way???

I would really really appreciate a solution to this decade old problem which I have yet to solve.

Thank you in advance and thanks for listening.....

Have you cleaned the gun lenses yet? We had that issue on our BBH Pro and it made the guns much better. Also the calibration menu tends to under-exaggerate the gun signal strength while they work OK in game. I prefer to just play a couple of rounds and see how the guns feel and go from there. Monitor brightness is also a factor too.
 
Yes, lenses cleaned, new optics installed and the issue is during game play, I just posted that video as an example.....

Thanks for the suggestions though.....
 
I tried every conceivable possibility with the exception of monitor chassis component replacement, I just do not know which component to replace!
 
Determined it is a display issue, thread here:
