Hey it sounds like u have did everything, so check and make sure u downloaded the right firmware on a good USB drive such as a 4GB and make sure format it with Fat32 before u download. Have seen that before with jump drive device and follow directions from Mfg website. If does not work then the CPU or Eprom has been corrupted and main board needs replacing.

Your LT-3780 LCD is only one part of a two-part television system. The LCD is the "monitor" and the HD-4001 "Media Center" is where the inputs and outputs are for the television. The HD-4001 was included with the LT-3780. They are connected together with an HDMI cable and a Serial Cable for communications. If you don't have the HD-4001, you can connect your cable box or DVD player directly to the LT-3780 with an HDMI cable. You will not have any means to connect more than one device at a time, as this feature was performed by the media center. You will also be unable to connect any S-Video, Composite, or Component devices, as these connections are only on the back of the Media Center.

Leaving your Mitsubishi TV turned on only postpones the eventual failure of the power supply.
