Frigidaire Frontloader Control board - I think

The washer has stop operating, The lights on the control panel flash on and off, Beep in no particular order. I think the control board is out but I am wondering if there are things I can do to verify that before buying a new one?

Remove the bottom panel and look for an yellow envelope with the tech sheets. Perform the troubleshooting as described there.
