Still no Power to Kenmore Elite Washer

I had no power to the control board, everything was dead. I replaced the control board (as was suggested yesterday) twice. The first one set off only a single beep when I pugged it in. Nothing else happened so I took it back assuming it was faulty and got a second. Both were from our local Appliance repair store who have never let me down before. The second one did the same, one beep and nothing. Is there some way I can check the "power" button to make sure that isn’t the problem? I can’t find an exploded view of the control buttons to see how to take it apart and don’t want to just start unscrewing things.
Help!
