Whirlpool Quiet Parnter II

I have a Whirlpool Quiet Partner II Model Number DU940PWKB0. This machine has worked well for us for years, no problems or concerns until just recently. The only buttons that light up/work is the cancel/drain and the air dry button. None of the other buttons light up or work. When I push the cancel/drain button it seems to cycle through to drain the machine. Other buttons do nothing at all. Any help would be greatly appreciated !!
