4485 : soldering looks like a mess. Bad layout, miniature copper eye sizes and poor mask design are the reason.
Removed. No changes.
Was almost impossible to solder some of the eyes. Boards are from 2012 as far as I know.
All will go into the bin. Worst project ever. Lesson learned: Never buy half started projects from people you dont know.
Thank you all for your great support.
Do not throw them away.
It is not likely that the solder bridge caused any additional harm,
but semiconductors in the area can be easily checked in place.
It is highly likely that you can find other soldering errors.

Looking at the copper side I see more issues.
Have a close look at all three-legged components.
It even seems one connection is missing the copper tab.
Otherwise :
let me be your waste bin. I fixed a lot like these.

Photographic angle of the component side does not allow solder inspection.
Remove excess flux on the copper side with solvent and toothbrush.
Remove excessive solder and reflow in certain places.
I had a short look only :

Ok guys!
One final attempt to save the world 😂!
when Soccer (Saarbrücken vs Kaiserslautern) is over i‘ll resolder everything suspicious.

Too much solder in many places. With small size copper eyes
like these it is advisable to clip the leads first and solder later.
