Have you tried replacing one or more of the bulbs?

Have you tried bypassing the headlamp switch and jumping power to the dash light wire?

Throwing parts at it may never fix anything, but will get expensive and time consuming.

Suggest you look over the printed circuit board first, before running out, and buying a new one. Look for any burned spots, corrosion, or loose connector pins. Ohm test each separate circuit, for good readings. If it's bad, sure, replace it. If it's good, start looking elsewhere, for the problem.
Ohm test the wiring that goes TO the circuit board, and use a test light, to see if your actually getting power to it. If not, look at your fuses.
