Cluster flicker

Hey guys so I got a problem with my gauge cluster. It is very randomly flickering the orange backlight. Only does it after being started up for maybe the first couple minutes. Sometimes it will do it and sometimes not. Still shows the miles when it does it just the orange back light flickers. Loose connection?

 

Dimmer rheostat perhaps? Have you tried messing with it when the flickering happens?

 

I did move it to a different position and that did seem to help. It hasn't done it since so I guess that is probably the issue. Going to go with it for a couple days and see.
