Yes, I had the same problem after about 1 year of heavy (daily) use. Unfortunately, my experience will probably be of little help, because I bought the extended warranty from Compusa (where I bought it) and they replaced the unit no questions asked. So far, the new unit is doing fine (after about 2 months of use) but I'm not sure that means much. . .

Sorry that I couldn't be of more help. Thanks, K.
