That only seems to turn on the set, if I press source 2580 I get a factory menu? see pics.
I've tried the factory reset in this menu

you may have HW issue or BGA at the main IC as it control all input sources include Tuner.
or could be too the tuner defect.. so or so need really deep inspection. but starting from BGA issue will be essential for the rest work. but blaupunkt famouse with rubbish firmware.. reset solve many problem.. not yours lol ... sorry i am out of any further idea.

Thank you for trying, I will try and read the firmware from the headers on the board I think there are 2 points 3.3v and a 5v header I will try with usb serial see what I get and take it from there.
Once again thank you for your help.
