PopBloom Shannon s50 light issues

If they are just connectors, then so be it, just seems strange they would add extra components rather than just solder bridge them or use wire.......

But as to the power, that is most likely where you soldered the resistor to replace the thermal fuse. If you look at where your power enters the board it says +38v and on connector 2 above it you can see the same +38v and GND next to it......

I would say it is the same going into the control section but you have probably blown a section of the track when you put a resistor in there and powered up.

So I would scratch off some of the white solder mask and find where you have a good section of copper track and then you will need to use a bit of wire here to your control section when you have found which component has blown. Definitely check the current drivers as there is something that is allowing too much current to flow and that's why things are blowing up.

Sorry just re-read your post (still not had my coffee) and you said that there is continuity to ground.......so yes, something else has gone and pulling it to ground.

I'm afraid it is just a matter of checking all the components and seeing what has gone......also might be worth taking some components off the board to help chase the issue.
