I tried to upgrade the firmware of my 40PFL9704H12 (latest version 26.78) to get rid of the annoying reboots that occur regularly after connecting my Motorola STB. Result is that the TV is not responding at all anymore...

I downloaded the software from the website, unzipped it, copied autorun onto the USB stick and put the USB in the port on the side of the TV

TV started installing the software update but during this process rebooted at least 10 times.

As a result the TV does not respond on anything.

Anyone has a suggestion how to move on from here?
