I"ve got the same problem. Never even played a game w/mine. I'm scratching my head here. Wondering if the membrane strip that runs from the power button to the board has a crack in it. Not seeing any w/naked eye, but not sure what else could be wrong.
If you find anything out, would apprecieate you passing it along. I'll do the same.
Guess thats what I get for buying a clearance item w/no company backing. What a waste of $50.00
