How do you repair a 1992 S10 Blazer if the electronic instrument cluster blacks out and comes back after 10-20 minutes?

The sauldering on the board behind the lighted display has come loose. You need to get it resauldered by someone who knows instrament panels, or it will do more damage than good.

My 92 Blazer S-10 4x4 lost all the lights on the dash. Local dealership quoted bet. $700 & $900. My mechanic took it out for me ($100), I shipped it to a guy in Canada who repairs these (he charged $125), the my mechanic replaced it. Been working perfectly ever since. I drove the car without the dash with no problem but the remove & replace only took about 4 days anyway. The guy in Canada in online, look up dashboard electrical repair.
