Chamberlain 41A4252-7A problem

Ihave a Chamberlain 41A4252-7A (Model 4100) that will not open or close with wall button or remote. The light in wall button, sensors and light bulb do not light either. Left it unplugged for several days and when I plugged it in the lights all came on. Hit the wall button and it tried for a split second and all lights went out again. Pressing the green button for six to ten seconds did nothing. None of the lights came back on. Do we think its the board? If so are there schematics available for this board there is not much on it to repair.
