I may be wrong but the symptom was one of a bad wiring job on some sockets. If you feel this is the TV, why not send it back at 3 days? No need to keep it?
So, I have a potential problem with my 3 days old LED. The TV works like a charm every time when NO HDMI is connected, so it's not a typical capacitor issue.
When HDMI is connected I sometimes experience problems that can be described as capacitor failure. Let me be more specific. I only have a really old HDMI cable, so it might be to blame:
-When I connect digital camera everything works (incl. Anynet) 100%, as soon as one presses on button on remote.
-When I connect computer via dvi adapter things work 100%, but each and every time TV "boots" in second attempt (power on, red light blinking, tv shuts down and then powers on).
-When connected to STB 100% failure (red light blinking in endless loop), unless reconnected to electricity.
