Didgital dash took a crap

I have a 91 S10 Blazer and my didgital dashboard took a poo al over me. About a year ago i was driving down the road and everything except the warning lights, trip meter, and speedo went out. If I smacked the dash hard enough then it would go back on. That does not work anymore so i need the right solution. Just was wondering if anybody else ever has ran into the problem whith the didgital dashboard. If anybody know what to do it would be great.

Here is a guy who says he can repair the digital dashes. they are very expensive new, and impossible to find used.......
