Hi all, just fired up my megatouch force and it locks up while booting displaying the message" touchscreen controller not responding" I have checked all the connections to the touchscreen controller and all seems ok, the green light on the touchscreen unit is on and the voltage going to the unit is correct. I fitted a new psu to the machine a couple of months ago and all has been working fine til now. Any ideas on what I can do next to fault find please? Many thanks. ..tim

When you touch the screen does the green controller LED increase in brightness?

If it does then the screen and controller are at least talking to each other...You might get lucky and have a corrupted hard drive.

Try doing a DIP switch 4+7 clear or reload the software if you have the discs.

If controller LED does not change when touching the screen I would be suspecting the controller itself and try swapping it out as a test with a known good one...
