Faulty MST-1001
I've just acquired an MST-1001 touchscreen, but it is slightly unresponsive and an area of the screen doesn't respond at all. I figured it might have been something come loose inside, but I can't see anything obvious. Has anyone got any ideas what to look out for?

'slightly unresponsive' might be a feature, not a bug for a MST-1001. According to some co-workers of mine, they should come with a touchhammer in the box...
. I assume you already went through callibration, the touch overlay is the thing to check.
I can't get to some parts of the menu because it is not responding in part of that area (which includes the lower part of the keypad for entering the lock code).
Push the (very small) button on the top left edge and keep holding it until the calibrate menu appears, then release it.
It does nothing. I've actually got it disconnected so I just shorted out the two pins...which does nothing. It looks like the button itself is broken. If I do connect it, it appears to lock up the panel.
I also can't get into any of the locked menus as I the keypad buttons 3 6 and 9 do not respond (and that general area of the screen). 8 sometimes works (I'm assuming the lock code is 1988...I haven't actually looked it up yet).
I've found a reset button, inside the screen, which, well, resets the screen (like a power cycle). Pressing and holding does nothing different.
Sorry...made a mistake - it is an MXT-1000.
Ah, that's a G4 capacitive touch, it doesn't have a calibrate option.
I have a MXT-700 that I use for testing. A couple of years ago the right 1/3 of the screen didn't respond to anything, had to be repaired by AMX. Don't know if it is currently still possible to get a RMA for that panel.
You could attach a USB keyboard to it (2 USB connectors on the back) to see if if it works; if it does, the touch part is defective.
You could also try with the ^VKS command (Virtual Key Stroke) from 'Control a device' in NS, although I don't know how to send the keypad 'OK', never had much luck with that.
EDIT: If the button is stuck in the 'on' position, that would seem to lock up the panel, I've seen that in older panels, like the NXD-1200, with the large button on the front.
It seems the MX series capacitive panels are dying en-mass lately. We've retired nearly half of the ones we installed already for exactly this issue.... partial unresponsive areas, or continuous triggering of areas. In a VERY FEW instances, diligent cleaning of the surface seemed to help a bit.
OK, thank you. I'll give those suggestions a try.
If they're all going that way, it makes me glad I never paid anything for it. I didn't actually need it - I just got it to play around with (I actually found it at the office and I was told it was no longer required, so I nabbed it).
