I'm having a HORRIBLE time with my Samsung LED 3D TV. Now, 3 of the HDMI inputs are non-responsive. I have tried 4 different brands of brand new cables. Can somebody contact me to help? I'm a Samsung loyalist with the following Samsung products purchased: 2 computer monitors, 2 TVs, 1 Galaxy SII Epic 4G Touch mobile, 1 galaxy tab 10.1...etc. / BUT...the experience with this TV so far has been very frustrating because of these HDMI issues.
