So the WEP finds the TV display again?
Upgrading the firmware works completely
with without the WEP connected to a computer.
Just unzip the downloaded firmware into the root directory of a USB drive and plug this USB into the WEP.
Now of course your difficulties start: because you can not see the WEP prompt on the TV, you'll need to guess which buttons to press. From the instructions:
1) ENTER (after ~10 seconds)
2) "select OK": this means without display you have to try 4 times: LEFT, RIGHT, UP or DOWN (my best guess is "left")
