As you can see on the picture it required some other DIPS to be jumpered to reset the F5000
I managed to brich the TV by messing up some things in the service menu, by following the other tutorial and the blindfactory reset I didn't manage
to get the TV back alive - but as mentioned above by jumpering the DIP it did
See picture below for the right DIP to connect..
rest of the procedure is as mentioned by DANIRED in his item
