I checked with service, and this issue isn't widespread, at least not at this point. So I don't have any suggestions or advice to offer, except to see if the TV board switching doesn't fix your solution, which you've already discussed.
Keep us posted! I'm curious to hear the results.

I have owned both of these products since June of this year. I have had problems with the tv while hooked up via hdmi with the ps3. While playing games or on the home screen of the ps3 I randomly get static display, black screen, input not found, and the right side of the tv looks like a barcode, along with audio static but not at all instances. This does not happen at any set interval only randomly. I have been through 3 different hdmi cables. I have replaced via warranty with sony the ps3. I still have this problem. I cannot determine if this is the tv or ps3 that is the problem. Or if it is just the signals getting crossed between the two. I have used the different hdmi ports as well. This does not happen with other componenets hooked up hdmi either. I have found others that have the same problem on different forums. Any help would be greatly appreciated. I have already contacted samsung and they were going to replace the main circuit board without even coming to look at it first. I dont want my tv opened up if it is just a setting or two I need to address.
Thanks
