Hello everyone I'm fairly new to repairs so bear with me please.

I have recently purchased laser war and the yellow pop bumper won't pop it scores and makes sound so I know the switch is good everything else seems to be ok with the exception of 1 resistor on CPU r13 it looks charred. I'm gonna go ahead and replace it but was wondering if that would cause it to not pop. I checked schematics and r13 is on the yellow pop bumper. Everything was working when I bought it.

And what would have been the reason for it to go bad.

Any help would be greatly appreciated as like I said I'm fairly new and know just enough to get in trouble.

I had one of my bumpers not work, turns out it was a previously bad board repair job. I did find this guide helpful: http://pinwiki.com/wiki/index.php?title=Data_East/Sega#Solenoid_Issues

Using their "grounding the transistor" tip allowed me to verify that the problem was on the board, not in the wiring or coil. I ended up replacing both transistors and the resistor near the connector for that bumper. To go along with R13, it looks like that would be Q8, Q2, and R20 or R19 (Which ever is right there next to those transistors.).

Good Luck!
