2004 Trailblazer Odometer and DIC won't light

I have a 2004 Trailblazer. The odometer and DIC won't light. I pulled the cluster and check all solder connections. (I'm pretty good with that stuff)
I flexed the board.. tugged, pulled and tapped... Nothing...
Will anybody help me?

I have heard--but not experienced--that Trailblazer clusters are prone to problems.

Seems to me that Dorman is big into selling "rebuilt" clusters, although Dorman quality leaves a lot to be desired--pretty much their entire product line is bought-in from Communist China. (I don't know where the clusters are repaired)

I know that repair instructions are on the internet for the electronic cluster found in late-80's, early 90's Toronados/Rivieras, perhaps repair instructions are also available for Trailblazer. Never looked.

This all assumes that the wiring and body computer are intact and functioning--the problem is in the cluster and not elsewhere in the vehicle.
