Dash/radio not working

[Alexaudi]

Hi,

None of the instruments on my dash are working - Revs, Speedo and small screen in the middle, plus the whole of the sat nav/radio. Things like the indicators work but just no light showing on the dash. They just didn’t come on the other day when I started the car, but after 5mins driving it all came on and worked no problems for a couple of days, until yesterday when it went off again and hasn’t come back on since. Any ideas on what could be the problem?

ive checked the fuses and all appear to be ok, as is the voltage in the battery.  Also did a reset for the radio but didn’t do anything.

Thanks for any help!
