Working on this Kortek 2003NA for a megatouch maxx. There is no high voltage or heater
coming on for the tube. I already replaced the caps and the HOT and no change. Are there
any common failures here that I should check? Fuse is good on the chassis.
 
I just repaired my Kortek and it was giving similar symptoms.. No neck glow, etc...

I resoldered the CR socket leads on the back of the neckboard, I guess one of them must have been a cold solder joint.

It fired right up.
 
check your voltages coming off the power supply section of the chassis. Something might be shorted out pulling the required voltages DOWN for that part of the circuit. I forget when the heaters run, I think 50v or something..
