DW 66516939000 control not working properly?

DW 66516939000 problem started with the delay start,when selected DW went into cancel mode. Few days after, DW started acting like it would start but would go into cancel mode after a few minutes. Found that if we unplugged it, it would sometimes work once. Replaced the control board but it now seems worse. Some of the buttons do not light up when selected and the dishwasher still does not complete a cycle. Would a new control panel fix the problem?
