Default judge dredd needs help

so turned on judge dredd today and noticed that 90% of the playfield lights don't work. pressed start and no ball came out. went to the test menu, no solenoids work and no flashes work. checked the fuses quick they looked fine. too late to do anything now but where should I start

What did happen when you pressed the start button? Anything?

tested a few thing today

j120 got 5.6 on all
j121 got 3 at 5.8 one at 3.8 and purple 0

and noticed that led 2 and 3 are on witch I read means low voltage

yeah I know it's a 148 page manual but
starting on page 36 of that manual is the beginning of the self tests
it also shows the solenoid testing locations
have you tried doing that test yet to see if it's all the solenoids
or just a few certain ones? l

Question WPC Schematics Manual ?

I've been looking at your manual. I was hoping to find schematic/voltage info for power supply Etc. Manual says standard boards are in WPC schematics manual. I would like to have that book. All I can suggest is double check every fuse with ohm meter, in and out of circuit(Power Off). Maybe pinballdaveH will soon see your post. C_S

seems like everthing has power all test points on the driver board have the right voltage 5-72 vdc. j115 has 7.5vac at all points. lights and solenoids under the play field all have power but dont work.
