jamex , If you can find the electronic parts (R+C+D), I can make some clear pictures how to install them.

Quoted from jamex:if you could make a photographic guide
@jamex,
Will do, tonight (european time) I have some time to make a guide.
Quoted from ChadH:Can you update these pictures and embed a description of what this is for future people coming across this?
done
Quoted from jamex:soldered on the opposite side of the resistor compared to your photo,
Not visible in that picture but I'm quite sure it is on the left side of R23, just like the picture i made.
Quoted from jamex:100v capacitors and told me they're okay
Should be ok but usually larger package.
That is wonderful news @jamex,
The 100V version of the capacitors is fine.
Personally I would have shorten the wires of both capacitors and stick them under the flipper board.
The same for the diode+resistor. When the wires are shorter, it will be sturdy enough and no need to mount it somewhere.
Congratulations on the successful repair.

Quoted from jamex:In my tftc the oes switch of the right flipper is connected as in the photo, both wires are connected on one point, is that right? Everything works fine. In my jp instead each point has its own wire connected
Thanks
Quoted from jamex:Nothing?
This has the same reason as Jurassic Park, the 520-5033-03 board has a design flaw where the flipper won't work when EOS fails.
TftC and JP are the machines that used this board. When the 2 EOS wires are tied together, the flipper would work without the EOS switch.
