This a possible cause for garbled graphics?

I'm thinking where some chips appear to have browned solder(Not connecting well or at all) that this would have the same effect as a rom chip that needed to be reseated.
My plan would be: clean the area with alcohol, then desolder and and apply new solder to affected areas.
Also what would have been a possible cause for this damage? Maybe a blown cap or something with some form of fluid in it?

board

From my experience it looks like a pop spill which will screw up your board. See if it is on the parts side also.
I usually take it and wash it with warm to hot water and scrub with a tooth brush the sugar water off. most of the time it will come back but once in awhile chips short out.
The same goes for mouse piss.
What....!

Parts side is perfectly fine and there is not sign of this mess anywhere on both boards.
 
Scrub it thoroughly but cautiously. That substance might have caused unseeable damage to the trace glue or the traces themselves. If you scrub too hard, you just might clean off a little more that you bargained for.

I scrubbed of with a soft toothbrush and 99% isopropyl alcohol and it appeared to remove most residue without damage. After I give it a bit of time to ensure 100% dry I'll try firing it up. I know one thing, the substance smelled bad. On another part of the solder side there appears to be a 2 traces with the green pcb layer removed a little bit, though the traces seem intact, I may try bypassing those traces and connecting their components via wire if it seems to be a problem.
 
What do you think spilled soda smells like after a few years? roses?

What game board are talking about anyway?

Half-assed information leads to half-assed answers. Example: I go pull a circuit board off the shelf, take a piss on it, then post a pic of it, and then ask... would this cause garbled graphics?

Its a Black dragon PCB, I just tested it and the character is garbled but the menu usually displays fine. Sometimes when I turn it on its all garbled. If I try to go into test mode(Or atleast what I think is test mode) it is complete garble.
I will post a video in a few minutes.
 
Verify that you are changing the correct dip for test by flipping dip 7 to on. If dip 7 turns the screen upside down, dip 8 of that bank is the test dip. If dip 7 does not turn the screen upside down, the test dip will be dip 8 of the other bank.

Yep, turns it upside down.
