Unit Powers Off

I recently bought the HT-S3400R Home Theater. I have connected (using hdmi cables) a cable box, dvr, vcr into the unit. Every time I turn on the receiver, it makes a click noise and then powers off. I have to turn this back on about 5 times before it will stay on. I thought it may be a problem with the spearkers causing a short but after unplugging all of the speakers from the unit itself - it still happened. i then tried disconnecting each of the hdmi cables one by one and it still happens. can you tell me what could be causing this ? I bought the unit 1 month ago. should i send back ?
