My Two week old SXRD is hooked to my cable company dvr which is hoe I get the HD video. Here's my problem. Two days ago the TV started to blink. The picture would go black for about a tenth of a second than the picture would come back for a few seconds and than "blink". I checked to make sure all cabels were tight. I was set for cabel repair to check out the dvr box today but the blinking stopped. I cxled the repair service, but was wondering if anyone has had this problem. By the way thsi is the best tv I have ever seen. I am 1000% happy I purchased this set. I would just like to have an ides what caused this "blinking" AS usual thanks in advance for any help or info.
