I realize the hardware/software is obsolete, however the plant that I work for has quite a few of the NT2s-122B-E displays, I am having a problem. One of the displays has been destroyed by using pointed objects on the membrane buttons , I set up an identical display using an identical PLC (CPM2A) , all settings I believe are the same . The replacement unit works, until I install it, then all I get is the back light, no boot up. I am missing something, but I don't know what. Any assistance would be wonderful
