Could you check something. There is a zener diode (D1038, I think) and a Capacitor (C1038, I think). (schematic is hard to read.) They are connected to J2 pin 1, ( second connector left of the cathode of the tube). Look up the zener diode voltage and make sure the voltage at J2-1 is correct. This voltage could impact the brightness.
