HELP! Merit Megatouch Encore 7 - touch not working

(1/5) > >>

mongoosetoo:
Megatouch Encore boots right up after changing power supply and re-seating security chip.  BUT - the touchscreen does not respond to touches.  Tried calibrating, but no touch there either.  I'm curious if the touch controller is missing.  This is the first one I've worked on, and I think maybe it's missing because nothing in plugged into the serial port.  See pic. 

Please advise and if you have the part, let me know how much $$.

Thanks, mongoosetoo

That stand off board with ribbon cable going into the motherboards com header is the ts controller. I can't tell from your picture if the ts glass is connected to it or not. Or if there is power going to it.

mongoosetoo:
Thanks mahkeymike...   This board show in the pictures is the touch controller, right?  When the machine is on, there is a green LED lit up on it.  But there are no wires connected to it other than the ribbon cable and the ground strap.  Should there be a couple wires leading off to the TS overlay?
 

mahkeymike:
Yes that's the TS controller.  There should be a nvram connector cable that goes to the overlay. Whats on the underside of that controller?

mongoosetoo:
I pulled the card out.  The only connections are the serial ribbon cable and the grounding/bonding strap.  There is really nothing worth noting on the bottom of the card.

Also, I may be looking at it wrong, but I'm pretty sure there is no overlay on the screen.  Not like it was removed, but like maybe it doesn't use one.  Is that possible?
