Make sure you go back into settings and check it's still selected. Also don't plug in with the TV on as some won't recognise the connection every time as I have two TVs that do that regularly. I find turning the TV of and on whilst connected usually cures it and if not then turning off the tablet or whatever your connecting to it and then back on helps.
Sounds silly but they are not like analogue cables and transmit other data up them.
Did you try to connect it in the exact same process as you did the day before?
Testimonial: "Yes intact I never disconnected it thing is it's working when now TV box is plugged in using same hdmi lead"
Great! God Bless!

Try connecting the red and white audio cords to your system from your cable box/satellite receiver instead of your tv. Worked for me.
SOURCE: Mitsubishi HDMI connection trouble
I have the same issue with my 73". Rather then going over all of my connections and equipment I'll just say htat I feel your frustration. I have been on the phone with Mitsubishi directly and it appears as though they have a free software upgrade that should address this problem. If you call 1-800-332-2119 and press 4 in the menu you will get someone to help you. Be patient. They will make you go through all of the fixes that you have already tried. They will mail you a flash drive that goes right into the front USB port of your TV. I hope this is of help. Good luck.

SOURCE: HDMI connection not working
I have a DCT6416 which is essentially the same unit but with a bigger hardrive. I just had the same problem and was able to fix it.
First connect your DVR to your TV with the composite RGB cables and disconnect the HDMI. Then power your unit on. Then power it off (using the power on the DVR not a remote) and immediatly press the menu button on the DVR (not the remote). A white screen with black writing will come up. Using the down arrow buttons on your DVR go to the bottom line where it says "reset factory default" Toggle down to that and then use the right arrow key and your settings will be reset. Then exit out of that by powering off. Now remove your composite cables and replace the HDMI. You should be back up and running.
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.

How many HDMI ports does your TV have? Have you cycled through all of them? Have you tried going into the graphics properties of the laptop (right click on the desktop and select "properties" then "settings) and setting monitor number two to "extend my Windows desktop onto this monitor"?
I would think it highly unlikely both laptops are faulty
