1988 GTA LCD Odometer problem- Help!

I just bought a 88 GTA and its having the problem where the ODO stays on for about 3 mins when cold and then disappears. I know this is a common problem as i've searched on the board and found that there is a problem with the PCB's.

Does anyone have a circuit diagram or know of the part that was bad on the board??? Its gotta be a heat issue with one of the components as if the cars been running for awhile and I turn it off and on and its only on for about 5 seconds but from a cold start it will run for about 3 mins.

Or if anyone has the GM wiring diagrams so I can at least take it outta the car and bench it so I know which wires go where that would be awesome.

If anyone has one of these cluster units for sale please let me know as well. Thanks!
