I plugged it in and all went well up to the last step. First they sent me the wrong one, then a week later (after calling them again) I received the correct one.

However, I did not download the firmware update myself, I had Toshiba send it to me which makes it worse. Since I updated from 1.04 to a ‘bad’ 1.05, maybe the TV thinks that the 1.05 on the stick is not recent enough, and won’t allow me to upgrade it again? If that’s it, then maybe a hex editor to make it versions 1.06 or greater? I don’t know!Ĭan someone please help me rescue this TV? TIA, Al. The firmware troubleshooting guide says “If current FW is newer than service FW version, it will not allow updating and no message box will appear (looks same as USB not recognized)”, from this Link: I leave it unplugged for over 1/2 hour between attempts, same thing. Then I went back and looked at the files, I saw that the first one had not downloaded completely, it was only 271K! I downloaded it from the link again (now 3.1 MB), put it on the stick and tried to start the firmware update again, but the TV doesn't recognize it, the LED on the USB stick comes on for only a split second during powerup, then goes out and stays out. When the power LED came back on, all I have now is a black screen, and it will not respond to the remote, except for power on/off. It didn't do anything for about a minute, I kept hitting 'OK' and then the TV finally did a power reset (the power LED went off, then back on again).

I followed all instructions to the letter, and I saw the expected screens, including the completion progress screen, and the last one which said to remove the stick and click 'OK'. To upgrade from 1.04 to 1.05, I downloaded the 2 files listed (STX40TAAD105_20090202.ecc & STX40TAAD-SAM40.ecc) from Toshiba's link and put them on a FAT32 formatted USB stick.
