Had this with mine. first, the power switch itself had failed after I had it for three weeks. the power switch was replaced, and then was working for a short period of time; then it started in again with the same symptoms. after that, the motherboard was replaced and my MDD worked normally thereafter. hope yours is just the power switch...
