I had a similar problem.

I used this guide to troubleshoot:

Scroll down to section "3n When things don't work - High Voltage section problems".
The photo shows the high voltage section of the solenoid driver board. Under that plastic line shield is a tiny 8AG fuse. This fuse protects the high-voltage side of all displays. I'm suggesting this as another place to check while you're looking.
Just as a reminder, you need to remove at least one end of the fuse from the fuse-holder to properly check for continuity on fuses (just in case you weren't already).

The above article has a really good walk-through for checking the power supply, rectifier board, and other items. Your troubleshooting method appears to be sound. Start at the source - where voltages are derived. Chase through the system until the fault becomes evident.

I'm glad that little fuse solved your problem (mostly)!

A 1/4 amp fuse is a touch too large. Yes, your displays will work but they are over-fused and exposed to risk of over-current. I used a 1/4 amp fuse temporarily for troubleshooting but I really don't recommend this practice. Get the right one installed ASAP.
This site has your fuses and many other parts:

Still talking about your displays. The missing digit is an easy fix. I used this article to track down the offending parts:
Scroll down to the part dealing with the level shifters.

As for playfield coils:
Use the flipperwinkel guide I posted above. Section "3i" will get you started. If it were me, I would start at the rectifier board. I have a 1984 system so it may be different.
If we have the same board (AS-2518-54):
You should find +43vdc between TP5 and Gnd
This circuit is protected by a 5A fuse labeled "F4"
Hope this helps.

Another handy thing to use while troubleshooting your coil circuit is to rig up a circuit breaker (sized appropriately for your circuit). Much better than "smoking" fuses while you look for a problem. Also, don't risk using too-large of a fuse while troubleshooting. You're likely to "smoke" something downstream and create a much larger problem.
