This unit has four HDMI ports. Input is not automatically set to the port that your devices are connected to. Take a look at the markings that correspond to the port that your peripherals are connected to, then use the Remote Control to change the respective HDMI port.
With your external device connected and turned on, press the HDMI button on the Remote Control several times in succession until the proper HDMI port is displayed. Output from your device should now be displayed on the screen.

Check the power supply modular cable connection that is by itself in the upper right corner. On the one my son-in-law has the double yellow jumper wire that connects to this plug in two locations was loose (not properly inserted) in the modular connector and had worked it way out.
SOURCE: Toshiba TV fails to recognize HDMI input
If the tv does all those symptoms but after some seconds the tv works and stays doing the job. THen the tv has a slow microprocessor to recognice the different resolutions or video inputs.
But if the tv cannot do anything and stay aout of signal forever. send the tv to the waranty. (no waranty? you have to use the component input instead to have digital signal reproduced
SOURCE: TV wont detect HDMI Devices except a pc.
Something is wrong whith the HDMI jack it's self, or the electronic switching is not sensing a signal is present. In either case the board that has the HDMI jack you are using needs to be replaced. Most all these boards are double printed, Multi-layered or both which prevents replacing the jack it's self. I do have a question though, do you only have on HDMI jack on the unit or do you have another one available.

You have to use the scart connector for on screen menu settings. Go to the video option and enable HDMI and/or match resolution output to your set.
You did not mention the model of the TV so here is another scenario,
Just because the TV is 1 year old doesn't mean that it is a 1080p capable, you could have set the HDMI resolution settings to 1080p and you will not get any picture if your set cannot process the information.
