LG WM2277HW will not respond to power button?

I ran about three loads of laundry through this washer yesterday. Woke this morning to run one more load, and found that the washer would not respond to the power button. I reset the power (by disconnecting the plug from the outlet) a number of times; spun the drum; opened the top lid and surveyed the main control board, filter, etc...; and even reset every electrical connection I could find. While skeptical this would work, I even emptied the "junk basket" filter on the front side lower corner of the washer. I'm open to replacing some of the parts in an effort to troubleshoot the problem but was hoping someone may be able to provide some direction/suggestions where to look first. I found a site that offers all of the parts I need. Any ideas/suggestions or experience with this problem? I have read around the site and seen that some of you are very experienced with this product, and I will end by sending my appreciation for sharing with the rest of us...
