OK..so monitor not working..spot killer on, game was working no issues and after several hours, then no screen. I can hear obi wan talk on start up. In test mode..I get high tones 1-13, 14 is low tone and 15-16 are high tones. Found that:
14) EPROM 1F or 1M on the CPU board +++
Would this cause spot killer to turn on and no monitor? I have all re-done "new" neckboard, chasis, HV flyback etc...and even bottlecaps. So I doubt this is the problem. I even swapped hardware, same thing...and even put in the Alan-1 WG6100 board and Transistor upgrade kit I bought a few years ago and same things. Also a vector labs kit on there, doubt its the problem...but just thought about it.
Just seeing some community thoughts. The three lights in a row, top left on the PCB do light up and then go dark after startup.
Thanks as always community.
