Game won’t boot. Played for months no issues then suddenly won’t boot up. All fuses are good.

Open the backbox and look at the lights on the board.

Do you have power at the service outlet?
I'd guess you've lost your logic voltage. The CPU requires 5V to boot and you'll get pretty much nothing if not.
Have a look at your CPU board. There will be 3 status leds. You can check them against how they should look here https://www.pinball.co.uk/pinball-problems/wpc-leds-explained/
If none of them are lighting up, then you've lost power to the board and it's time to check your driver board.
LED4 should be lit and you should be getting 5v at the test point (tp2 I believe). If not getting 5v on that test point, then chances are your bridge rectifier (a series of diodes on the board) or your smoothing capacitor are bad.
If the CPU leds are lighting up but the middle one isn't blinking, try unplugging all except the power to the cpu board and see if it will boot afterwards (middle led blinks).
Quoted from PinballGurus:I got 4 red lights.

In your picture, the 3 leds on the smaller board on the left are the ones I'm referencing. They are all 3 next to one another in a vertical formation. Is the middle one blinking?
No clue how that could have happened when the game was working fine for months and same day I drop it off they go out?
If you've recently moved it, definitely reseat your connectors. They can wiggle loose during transit.
Past that, check F114 (I think; going from memory) on the driver board with a dmm to see if it has continuity. If so, check the 5V test point.
I seem to have the worst luck dropping off machines only to have them quit right after. Does this only happen to me?
Quoted from PinballGurus:I don’t have a schematic.

Schematics are in the manual.
The only LEDs that turn on are 1, 6, 7, and one other on the mother board. No other lights turn on. Is there a fuse I’m missing somewhere?
So I just noticed when I switch the game on via the bottom. If I do it slowly the game lights with flicker. Could the switch be bad?

You would get no lights at the motherboard or anywhere else if the switch was bad. It's easy to test though. Unplugged, check continuity on either side of the switch. Should be open when off, closed when on.
Quoted from PinballGurus:F113 is +5v
Quoted from NoMonkey:F105 should be the 5v fuse.
Ok, I apologize as I didn't realize popeye was WPC and not WPC-95.
If F113 is good and TP2 isn't showing 5 volts, check your incoming AC voltage on J101.
If that passes, then you need to make sure your continuity is solid from J101 all the way through to at least BR1/C5. It's important to test that the legs of BR1 connect to C5 as they are top-layer traces. It's possible there are cracked solder joints at C5. I'd inspect that cap for bulges/leakage and reflow the solder to see if it repairs potentially broken traces directly underneath it.
If that all looks good, then test BR1. This can be done inline so there's no need to desolder. A quick google search will give you some info/videos on how to perform the test.
If all else fails, I'd replace BR1, C5, and C9.

Heading back out today with a Doctor Who boards. They live out of town so I’m going to get it going then figure out the cause at my shop. My guess is CSJ somewhere on the 5v. I’ll report back later. Thanks for your help.
So today I took another board that was working and swapped out the BR2, C5, and the LM323K; and put the board back in and still nothing. Any other ideas? Still no 5 volts???
Normally lit. Indicates presence of regulated 5VDC. AC voltage is rectified by BR2 and smoothed by C5. The voltage is regulated down by the LM323K at Q1. This 5VDC power is shown as "+5V Digital" on the schematics. This power is fused by F113.
