Monitor working perfectly but it's monochrome now ?

Weird I turned on one of my games and it's working but the colors are monochrome !
 
Which chassis? There is a resistor on certain ones that causes this if you do some searching...
 
have you tried a different tube?


No and actually I did see a flash on the screen before it went bad?, turned my game off back on and then saw the monocrhome type picture :



I hooked the monitor in a different working cabinet, with a different PCB same result so 100% it's the monitor.
 
Are you running it with a 1943 or a multi?

Sure you have the video connector wired properly for this monitor? Not all monitors use the same video input pattern (unfortunately)...

Now all you need to do is jammatize a pc and run Oregon trail !!!
 
looks like your missing red and blue.... at this point id make friends with somebody who has a rejuve to test your tube. I have a sneaking suspicion that cheapo tube just krapped on ya.
 
No it's an actual 1943 PCB... not a 60 in 1. The wiring is perfect because I just turned two cabinets back to back (1943 being the one that doesn't have the problem) to use the wiring from another cab, so 1943's colors are perfect the wires are correct its the monitor..

I think it could be the tube ? Not sure what should I look for on the chasi ? I don't see anything that's burnt. Again I did see a flash on the screen initially which is what I think caused the problem.

You don't understand my point. Unless the other cab you tested it with has the exact same monitor, then you may have an issue. I know most monitors take an RGB-ground-sync-sync signal, but there is at least one that takes a GRB-ground-ground-sync signal, and another that takes RGB-ground-sync-nothing signal. Your new monitor may need it wired up differently than the original monitor or the monitor in the other cab...
