Cerbo-gx frozen screen and shuts down after touchscreen is touched

Hi , We are getting a random problem on cerbo-gx we had a 50 screen and have just replaced to a 70 screen and it came with 2 x EMI to go on the screen cable. Which has made us thing that there is a possibility that the static charge from a person touching the touchscreen could be enough to cause the cerbo to freeze and then our entire system shutdowns 5mins after this. Have spend last 3 months updating firmware and trying to problem solve. Has anyone else experienced anything like this?
