Can anyone tell me the brand of monitor/chassis this is? Came in my Carnival. I have high voltage, but no neck glow. Don't want to troubleshoot this blind without schematics.

I tube swapped it as all the guns were dead in the other tube.

I answered your question on the Carnival thread. :rolleyes:
I don't think you really needed to post a redundant thread.

Now, finding the schematic might be a different issue.

Maybe this?

measure AC voltage at the 2 heater pins where the neck socket is soldered in, it should be around 6.3V AC if it's working.
 
i was able to find the heater outputs off the board. 0.9v. In looking at the diagrams this appears to be an output off the flyback, through a single resistor (good) to the heater output. So we're going to say this one is junk, and time to pop in another vertical monitor.
