Has anyone having this Sony Google TV experienced problem with its remote? This is my 2nd unit with the same problem (sent the 1st one for a replacement). Once every week or so, the remote can't communicate with the unit. Replacing the battery doesn't help. Green light on the side of the remote keeps blinking when power button is pushed, but nothing happens. The only way to fix the problem is to unplug and replug the unit. I really like this unit for its features but am very concern about this persistant remote problem with two units now!
