Digital cluster out itself?
 

Hello, I was wondering if their is a possibility that the digital cluster itself could go out? I've recently gotten a new power supply and the cluster will come on, but sometimes it'll go out again. When it is on some parts of like the rpm graph and the speedo numbers are already out. I was wondering if this could be the cluster itself being faulty rather than it just losing power?

My ('83 T) entire digital cluster stopped working today as well, and I haven't found any answers on here. But it is only the digital part of the gauge cluster, because all of the other lights etc. work fine. If you find any info, let me know.
