Hey all I have a Williams Jokerzs and the full quad display stopped working. Game plays blind and everything else works 100%

For a while the when I Turned the game on..the display was fine then some is the "pixels" started to fade out, and some were fine. This happened for 2 months. I tools all the connectors off and reseated them..all the digits briefly turned on the all faded our to black and no display. I reseated all the connectors on the machine and checked all fuses (good). Now what?
Thanks!

Not a DMD machine. Regardless, looks like HV supply have have gone out.
Check HV fuse first.

My DMD game (yours isn't) just had a similar problem, but mine faded out slowly in 5 minutes or so. Replaced the DMD driver board and it works great now.

Thank you everyone! Guide said r1 and r4 39k ohm resistors go bad a lot. I replaced them and I'm back 100% yay!
