I've owned the TV for about 2 and a half years, and recently it has started having problems maintaining sync with my Comcast Motorola DCT6412 over a DVI/HDMI cable (cable is from Blue Jeans).

The cable box is currently the only component connected to the TV via HDMI, so it's hard for me to determine if the problem is with the cable box or the TV. The picture comes back after power cycling the TV, or by disconnecting and reconnecting the HDMI cable from the TV or cable box. Power cycling the cable box does not seem to fix the problem. I've attached a picture of the TV after it lost sync. The problem has been getting progressively worse, and today it has been doing this approximately every 20-30 minutes.

I'm looking for suggestions on where the problem is (TV or cable box), and, if it is the TV, what can be done to fix it. Thanks very much for any help.
