Picked up a Merit Force 2007 upright LCD cabinet, and was working fine apart from a one area where the tape that holds the membrane onto the LCD screen, and adhesive residue had dripped inbetween both parts, carefully removed the touchscreen membrane albeit was held on with carriage bolts as the adhesive had literally melted off, and become a sticky mess, anyway cleaned that with the proper cleaner, glass clean, use the proper tape to restick the membrane to the LCD and now the calibration is way off, the green light on the touchscreen control box flashes when you touch the screen, anyone have any thoughts on this ? thanks

even thou when I run the calibration setup and press the center of the cross, once both crosses have been touched, it still seems likes its a few inches off
 
okay after much screwing around with it, new adhesive, cleaned it over and over, grounded it, still the same thing, did see on merit site a couple of update pdfs that mention about a file that is used to resolve a similar issue? but on the link page ,its dead, this is becoming a major PITA! as everything seems to be clean, intact, the controller acknowledges the touch as it gets brighter, but the calibration is way off and unusable :(

anyone have any help that can share?
thanks
