FIXED :gunforce working but only in red
got this gunforce locally but it’s only playing in red???
What could be the cause of this?
Also anyone know what the third set of dip switches at the top right of the board do?

Re: gunforce working but only in red
Just noticed at LC3 one of the capacitors(?) has been broken off. The others have cold solder cracks also. Can this part be found/anything equivalent to it ?

Re: gunforce working but only in red
Yep almost certainly. I guess you have other PCBs working OK on that monitor so you know it's a board fault.
I looked into these components at one point, they are a cap and 2 resistors combined I think.
Maybe worth reflowing the pins on the ones that remain to see if you get any other colours back?
Specifically look at pins 13 (top side) and 'N' (solder side). See what components they go to.
13 does seem to go to the missing component LC3. That'll explain your lack of blue video.

Just did that but still only red.
LC4 is snapped flush off too on one of the resistors -_-
Cap says 101m 100v

Yeah no joy finding these components again.. hmm.. let me see if I can find schematics.

Just a bit of an IREM pcb fan here. Would love a Gunforce 1 + 2 someday. And an Undercover Cops when I don't need any kidneys.
