Dash lights not working

Hello everyone. Im new here but I have a small problem. My 2004 f250 6.0 was and still is driving fine but a few days ago all my dash lights (illumination) went dark. I can see odometer, all gages work, inside dome light works, but at night I just cant see anything unless i put a flashlight to the gage cluster. I find it unlikely that all the bukbs in the cluster burned together at the same time. Any ideas or help will gladly be appreciated.

Checked fuses? Dash illumination switch?

Forscan lite will read codes on dash cluster and other Diagnostics on your vehicle. I have forscan full version(laptop) forscan Lite and Torque Pro. Never use ScanGauge so I don't know if they'll diagnosis it or not.

Check the wires behind the dash going to the illumination switch. Did you check the appropriate fuse(s) as tfunk88 suggested?

Oh and i forgot to add, the rear lights went dead at the same time so no rear lights on the truck.

edit - also check the wiring to the tail lights! Interestingly enough, a short there can affect the dash lighting.

I have the 2004 van and the instrument cluster has ground inside the unit. My instrument cluster would go on and off intermittently. I sent to Circuit Board Medics for rebuilding. It works fine with the exception that the speed displays 5 mph when not moving. I checked the speed with my GPS and it's reading 5 mph higher. Keeps me from getting speeding tickets!
