Hi - I've been trying to apply the 12.0.7 firmware upgrade for my Mitsubishi WD-73837 for several days now with no luck. The TV came with version 11.0.0, which it still has. It doesn't have an ethernet port so I need to do it from a USB key. I've tried three keys, but no luck. On Monday I'll call Mitsubishi about it but am wondering if anybody else has had trouble getting the firmware update to apply. I followed the instructions exactly.
Thanks
Thanks
