Quoted from Catch22:Hope this post is allowed, trying to diagnose which parts to buy and replace, for this burnt board. Would be great if you could guide me to the best place to buy them as well. Thanks in advance. [quoted image][quoted image]
Pop bumper coils, or the switches associated stuck closed. Easy fix if you take your time. Test your coils. Visually inspect switch contact points.
HSmatrix (resized).jpgQuoted from transprtr4u:I would send it out and be done with it!
Looks rough
Looks rough from the pic, but just the resistor exploded(from what we can see) causing the secondary burns, which usually can be cleaned up, if they test within tolerance.
I agree, if you don't do board work, send it out. If you feel like you can clean it up, test the components and maybe discuss it with some of the board gurus here, they will usually be honest about fixing it or shipping it out.
Quoted from Catch22:I totally agree, That is why I had a technician double check everything under the playfield and he asked me to post on here to find specifics for me to source the components. I appreciate the concern and post ty.
I have a complete List of the parts for system 11 MPU, just message me and I can send it to you.

Quoted from KJL:Wow, I've never seen a switch matrix do that with all the system 3-11 games I have had. In addition to what people said about parts I would (or have your guy) figure out why that burned.
Good luck
Sometimes when you work on stuff, things shift around, stuff will touch other things and BAM.
Quoted from KJL:Yep true but do you use that as your troubleshooting approach?
Not as my main approach. If I go through my normal test routine, I always default back to what did I do last. Occams razer will apply if all else fails.
