I just replaced the Monitor and when i put the machine back together I have a ghost touch issue. This goes away when i pull the front of the cab back a little.
I have tried bending the top front tabs back a little to get the touch screen away from the CRT, which seems to work a little but still have the issue when bolted back together.
I have scotch mounting tape in between the cab and touch screen overlay to hold it in place. it seems like there is about 1/4 inch or more space in between CRT and touch overlay. Does anyone know how to remedy this issue? I'm getting frustrated haha.
Any help would be greatly appreciated. I have gained a lot of knowledge from lurking but couldn't find anything search for this issue.
Thanks

Could be a ground issue. Did you make sure the green wire comming out of the overlay cable is grounded?

Fordman9870:
Thanks for replying...ground is good, i put a piece of foam in between the CRT and overlay and it seems to be OK for now. I wonder how the guys in the field did it when they were sent out to work on them. This little issue took me hours to fix and its really only a band aid.
If anyone has any other ideas please post, Thanks

Well, i can't speak for operators in the field, but there should be non conductive single sided foam tape inbetween the front bezel and the overlay. I have seen this foam tape get filled with all kinds of nasty stuff even seen metal shavings in the foam. My guess though #1 grounding issue somewhere.#2 lose overlay wire. #3 you have something putting pressure on the overlay.

MahkeyMike,

I think your on to something, I checked and installed new scotch tape and used some foam in between the overlay and CRT.
it works great but, when i go to put on the left side of the cabinet. when the cabinet touches the touch screen wire a ghost button is press. i checked the green overlay ground wire, it is tight. so i wiggled the wire for a few seconds and it ghosted again (it ghosts a lot quicker when i try to shut the side cabinet. is the overlay going bad?

Also Is the overlay wire suppose to stay on the outside of the monitor frame and only duck inside near the controller box thats mounted inside?
Thanks
