Touch screen failing & pendant recommendations

Yesterday the touchscreen started blinking on and off during a carve, the connections all seem to be tight, should I be replacing the screen for my Buildbotics machine?.
I do have a monitor running off the computer which is not touch screen but does give good display.

Thinking about pendants, as my game controller is starting to get a little bit tired. is it possible to plug in a pendant to the Buildbotics controller and if so does anyone have a recommendation as far as brand and model?
Thanks for any help.

Damn I was in England in November 2023, could have brought one.
I have a ship to address in the US wonder what the cost would be there?
