Dip Switch malfunction
« on: January 11, 2012, 02:00:35 PM »
I have a malfunctioning dip switch on my Popeye pcb, for example when I set it to 3 lives there is only 1 and it is always on the hardest difficulty.
Are these switches could be simply replaced, or only the Nintendo type match to this pcb?
Thanks for any inputs. ;)

I think any will do since its just like a jumper ..

you can even solder a bridge in there if you dont want to switch them anymore..

Hey Andre, how do they handle if you order and change the shipping adress to bela ?

It looks different, but I think it would be working on my pcb. ;)
I have tons of non-working garbage pcbs, I think I will steal one from those, it will be also a good soldering-desoldering lesson for me. :D
Thanks for your help. ;)

there is two options:

a. I hope you got a desolder station or a very good pump...

b. if not, break away all the pcb around the dipswitch and between the legs so they are separate.
then you can desolder the pieces of broken pcb off one by one...
(the opposite of the "ic cutout - desolder separate pins technique"

but i am not sure the dipswitch will survive method B  ;D

Be aware it may not be the dip switch itself that is at fault. I had a Hyper Sports board which failed to register any changes to dip switches, it was the logic chip the switch fed into that was at fault.

Ok thanks, I will also try to investigate that. ;)
