Blue screen signals the fact that the tv doesn't receives the signal. The HDMI connector itself is faulty. Open the back of the tv and look at the solderings for the HDMI pins - they are loose or broken.
In that case either the image processor in your tv is no longer capable of decoding the HDMI stream or the routing chip no longer processes the HDMI signal. In both cases the mainboard will have to be replaced. I don't think it's worth it, just use the component input, the loss of image quality will be negligible.

I have 2x 57 inch Mits and 2 HD boxes from Directv. I swapped cables and HD boxes and they work on my second tv. Therefore it is not the HD box or the cable. I have 3 HDMI inputs and tried them all and none of them work. I checked the input and see no obstructions. The tv does recognize the cable when I plug it in, there just isn't any picture or sound.

I would think if the tv senses the connection, then the internal connection is good as well on all three inputs.
I have a 1080 P Mitsubishi wd57733 and the hdmi from DIRECTV HD does not work. The tv senses the connection but it just shows blue. The component input works fine. I tried reset and setup and even tried my hd box on my other identical tv where the hdmi works fine without any configs. Any ideas?
Mitsubishi agreed to replace the board at no cost through their warranty assistance program. I just pay for the labor with the repair service! Thanks!
Yes as it pointed me in the direction of where the issue was. Thanks
