I just fixed a major issue with my MMR standard so I hope this helps someone. I've had my game almost two years at this point with just under 300 games played (Built in early 2018). The other day I booted up my MMR and received the following message:

I see that others have fixed this problem by reconnecting the Ethernet cable but in my case that did not fix the problem. I replaced the cable with a new one with no success. I checked all the fuses and voltages; all were correct.
To resolve the problem, I had to buy a new PCB from PPS for $300. I opened a support case with CGC and spoke with Arturo (super nice guy!) and confirmed my problem was a dead playfield PCB because there are LEDs around the PIC that were not lighting up. He initially offered the advance replacement program, which is $125 + shipping both ways to swap for a working board, but after waiting more than a week he was unable to send a PCB due to the current MMR run.
Notes on the swap:
1. You must transfer all white PCB standoffs to the new PCB.
2. You must transfer all hex standoffs to the new PCB.
3. The original PCB had Kapton tape over some of the pins; this was not present on the replacement PCB from PPS. I bought some from Amazon.
4. There are a lot of connectors so label them well! I bought colored dots, placed them on all of the connectors and took many pictures.
5. The solenoid and switch/LEDs connectors are different types so you can't mix them up.
5. I had to remove the slingshot brackets/coils; they were in the way of removing the PCB.
6. You do not need to remove the trolls.
