It's possible that the ignition switch is failing, but you would usually see other systems affected. Wouldn't hurt to try. If it doesn't fix it, at least you'll have a good spare switch.
I think the cluster has an onboard regulated power supply (I honestly don't remember for sure). Since the entire cluster is affected, that would be suspect.
I'd also check all solder joints, especially the connector pins, and the ribbon cables/connections between the front and rear halves of the cluster.
