I recently bought Samsung Model 55MU6290. I periodically have an issue where the screen will go black for a few seconds. This does not occur very frequently, but is still a problem. I have tried many things to fix this. 1) Replaced HDMI Cables 2) Replaced Surged Protector 3) Reset settings to factory default. 4) Checked for newer firmware, none exists 5) Test different hdmi ports with different hdmi cables and devices 6) I disabled Auto Motion and Power Savings options, to see if that was causing the issue. This problem occurs on all HDMI inputs with different devices; however, I do not think I have seen this issue on coax. I took back one of these TVs because of this problem and got a replacement. Now the new TV is doing the same thing. What other things can I try?
