MD4 touch screen not responding

We use the MD4-7 for all our systems.  I have one of my customer with a Fairly new(3 years) but rarely used unit for a test bench.  He complains and I witness that is touch screen is often not responding.  It is mounted on an aluminum test bench.  Sometimes if he moves the unit away from the bench it seems to respond better but not always.  We tried to ground the unit but it did not improve.  Do you think this is an hardware issue or is there mounting issue we need to look at?

I believe the issue you are seeing here is the same as reported by myself and also Ethan Zeman.  The touch input part of the screens seem to fail around this timing mark.  I have sent screens back to OEMs for evaluation, awaiting responses....
