New Holland HW320 Electrical Problems

I'm having problems with my HW320 swather. The machine worked just fine for 1st crop. Went to start it to cut 2nd and the battery was DEAD. Charged the battery and started the machine and found I have no display on the display panel and have lost all functions for raising and lowering the head, turning on the reel or knives. The display panel does illuminate. Any one had this problem? If so, Did you end up replacing the EIC? Looking for any information or guidance on this issue. Thanks in advance!
