Now to my problem:
I noticed that in D series service menu the model is "greyed" and can't be modified.
Unfortunately after a crash, my TV bricked and I had to reset the eprom.
Now I have MODEL: NONE and TYPE: NONE
Also, in service menu, I have LOCAL SET to the wrong country.
Is there a way I can set this back?
Please help.
My 55D8000 now has no functions and flickers a lot

(I also have the serial port connected if needed)
