Weird MK3 PCB problem.
<< < (3/3)
Savannan:
I'm heading to work now..Goin to take that PCB with me and remove/label all chips...then see if I can find something obvious.  Just the simple stuff 1st  ;D

My only question about doing that is....Once I get the PCB warmed up and is working properly, I spray the can upside down to freeze a area of the pcb.  Look to see if I see problems...then move onto another section.....all while the PCB is connected and turned on....

but is that freeze spray conductive? should I be worried about it shorting out something?

Just don't go crazy. You just want to cool it, not freeze it so frost forms. Frost AKA frozen water, when it melts, IS conductive.

But that is the general idea.

Well I took my PCB to work and I did find a solder point cracked,  re-soldered it, powered it on and same thing.

I think I'll head to Radio Shack today and see if they have that freeze spray.  The game looks/plays great after 30 mins of it being cold, but its kind of a pain.

**EDIT** Just looked on Radio Shacks web site and no freeze spray.  Is it under another name?



Malenko:
try it the other way, push on chips while its cold and see if the issue goes away
