lcd readouts on instrument panel on workhorse chasis

There was a recall on the panel back in 2004 and I have seen a few posts in the last few years that talk about a service bulletin but no one has ever posted a link and Actia didn't know anything about it when I called them. I have never seen a warranty statement on the panel.
The recall info is:
50402-C

The Actia LCD panels of that vintage had a known problem that was fixed by Workhorse warranty when they were still in business. If I remember right mine was fixed with a new FW update. Probably your best bet now is to talk to a Workhorse service center and find out what they can do for you.

If you go HERE you can download the complete manual for the Actia instrument panel. I think it has what you need.
