What about the thru hole plates? If they are missing on the cap...

zaza, I like that illustration....have you got the rest of the board?

zaza...this drawing looks to be F-ing fantastic!!!!!

If you tag each of the traces on the schematic and cross reference those on the drawing a hamster should be able to diagnose the board.

Thanks for the effort!

zaza, perhaps you don't realize the importance of what you are doing. I can read the schematic without any problem. I can follow a trace on a board without any problem. However, if you overlap the two, that's pretty powerful. Half the time I can't even find a component since the board is not laid out like the schematic. Every time I'm looking for the TP, I need to remember, "oh yea...it's tucked over here".

Think about how powerful this would be if you labeled every trace on the board with a code. F001 for the the first trace on the face of the board. Then you go to the schematic overlaying F001 on the corresponding line. This is especially important when a thru-hole-plate is required to complete a circuit or there's a trace under a component.

Yes, I agree, not interactive (although that would be way cool). I imagine there's board design software out there, that you could paint the board, apply components and it will show you the flow, voltage drop, etc....but I would venture to say very expensive and not for the faint of heart.

I think your effort will be a big help.

Cold solder joint
Broken wire

Just to rule out the slam switch doing something odd here.... flick the switch and see if something happens.
