did you sort this out? I just got a POTC, same symptoms.
my board pictures look the same, with L5 led off but all other ok

Thanks, i'll dig out that.

So first step is to remove connectors.
F10 fuse blows on turning on, i'll have to check if it's a transistor issue or playfield.

Hope to sort it out after xmas break.

so i had a bit of time today.

F10 fuse blows when J6 is connected. All other connectors are working well, all voltages LED are green and all fuses are working.
Flipper coils, ship, chest and spinner are working well.

Any obvious reason on J6 that would cause J6 connector to burn my F10 fuse ?

I'll connect each wire to determine which pin is creating the issue, but any known reason would be helpful in debugging

and by the way, happy christmas holiday and happy new year

Yep, exactly my plan.
I was just wondering if there is a known weakness on this part of the potc.
I'll keep update

Debugging time this morning was productive.
I've found the bad boy, namely pin 6 on j6, "flash back right".
I did not found a map of all flashers to determine their physical location, i've found one at the back right top part of the playfield.
The continuity test gave me a beep with or without bulb, so there is a shortcut somewhere..

To confirm my thinking, i ended by cutting the blk/blu wire at the ribbon level, booting the flipper and fuse is ok.
Game is fully working with the exception of these flashers.
I'm quite happy as ship is working well, and some of the pins on j6 where related to this toy..

I'll continue my investigation, but all clues related to flashers issue are welcome
