Hello.
Entering the service mode, I changed the model of the panel. Since then the TV has no picture.
There is a way to fix this.
Thanks.

You had better hope that a Factory Reset will bring your ten-year-old, non-UK, TV back.
Such menus are for service engineers with tools, equipment and training, not for the likes of you and me 😢
My favourite bedtime reading is a Sony product manual…

Hey @ilektronio12, you can try a forced reset as a last-ditch attempt to fix it, and hope it works!

Hello.
Thanks for the answer, but as I said, the TV has no picture. How to reset it?

@ilektronio12, the link illustrates how to perform the forced reset using the TV buttons, not the TV settings. If that doesn't help, I'd recommend contacting Sony directly to see if the TV can still be repaired at their service centre.

Hello.
Finally, I found the service manual and on the service mode page, I measured the movements needed to go to the panel settings, I did them blindly, and the TV came back on.
Thanks.😁
