Radio/ MFD problems

[Yorkshiregeordie]

Good afternoon all....I am looking for someone who can help me with my radio and mfd problem.
The MFD does not always come on when I switch on the ignition and it sometimes does come on. It might stay on for while or go off randomly for no apparent reason. It may come back on during the journey or it may not..
Peugeot 307 sw 1.6 hdi 2005 model.
The radio works with or without the display.
Would also like so e help getting the radio code please

There is no radio code. The radios are VIN-coded to the vehicle.

The display LCD may be on the way out, so likely needs a replacement.
