sonny,

I would recommend getting the unit repaired. It does have a 1-year warranty, so I'd definitely recommend getting the unit inspected. You may also consider working with the store management if you'd like to exchange it; often times, department managers are willing to offer some assistance in that area as well.

I would not consider that symptom normal, especially if it happens on all inputs.

I believe most retailers offer a 14 or 30 day return policy. I would find out what that is, and make the best decision for your situation.

Keep me posted.
