Quoted from TheRick:Hello all
I’m new to the pinball world and I have a beautiful pharaoh that just died on me. All the light work and sound but won’t load games.
I was able to get a 7 on the diagnostic board which leaded me to believe I needed new roms. I ordered a set from Dave when checking my manual it showed that the IC20 and IC17 were originally backwards in the game. I tried switching them both ways and now I have no under the playfield lights and I’m getting a error code 9

I learned this recently.
The little notch in the top refers to the correct placement of the chip. So if the notch on top of the chip lines up with the notch in the socket then it’s lined up properly.
In the picture all your chips were seated correctly and someone just put the labels on facing the other directly, but the chips were inserted properly.
If you swapped them around and didn’t ensure the notches are on top, you blew them up.
If that’s the case, you may want to send the board out as slochar said. There are many professional who can fix them.
Coin op Cauldron comes to mind
