- What is that device that is being plugged in HDMI of TV? Bluray, Cable Box, PS3, DVD etc?
I tried Blu-ray and Laptop.
- Did you confirm the video source in any other TV's HDMI input that isn't working in KDL46EX400 HDMI input?
I have only one TV. However, I tried two different HDMI sources, blu-ray and Laptop. Both them used to work find and the likelihood that both of them malfunctioning is very low in my opinion.
- Did you reset TV through TV menu?
I tried it from TV Menu, unplugging the power supply and holding the up-arrow from remote when turning the TV on (your answer to one of previous questions), unplugging the power supply and holding the power button for 10 seconds when turning the TV on, unplugging the TV and holding power button on for 10 seconds on each device from when the power is turned on.
- Did you confirm the HDMI cable in this connection setup?
The TV seems to know the name of the device when it is receiving through the HDMI (it is displayed on the screen), but after 5 seconds or so, it says 'no signal'. I even opened up the TV and checked if there are any loose contacts. I could not find anything wrong visually.
