How to fix Digital Speedo?

[TheGreatNate]

My digital speedometer went out and I've searched and found mostly that it's a soldering point that needs to be resoldered. But I have been unable to find where someone gives the specific point to do this resoldering. For those of you who have resoldered what did you do? Resoldered everything?

I'm thinking of taking it to a speedometer shop, but I'd rather save my money if I can fix this on my own. So help me out! :D

Thanks
Nate

Top this one last time before I take it to the speedo shop.
