Question 1985 Digital Dash Troubles

Greetings - I just picked up a cherry, Aztec Gold, 50,000 total miles 1985 ZX. Two great road trips after purchase and I am having digital dash problems. It is intermittent, sometimes on and working fine, sometimes totally dark. My local mechanic says the power module is on the fritz, he tried to re-solder, he can't get a replacement, and is wary of rebuild services. I am obviously not the first Z31 owner to face this dilemma, but the past links are old…what do I/should I do now?

if it works sometime then it isn't shot there is a loose or poor connection somewhere. find a new mechanic and/or check ebay for replacement. Does he really know how to solder many people don't altho they think they can. they use a 200 watt gun and burn up the board. 15 watt electronic duty solder is what you need.
