Hi everyone,

Great site. Nice work everyone.

My buddy just picked up a used Hurco km3p. We pulled out all the boards and cleaned them thoroughly. We're powering it up and the lights flash on the keyboard then a few stay lit. That seems normal, but both CRT screens are totally dead. They didn't work at the time of purchase however a couple years earlier they did. Any thoughts on trouble shooting CRT's? There don't look to be any failed capacitors. The elements in the back don't even light up.

If one was bad I could believe it, but both being out at once seems like it could be something other than the CRT's. Any help would be greatly appreciated!
