issue

I finally found the pinout for the neck and everything tested good on the
tube. ;-) I found a faulty contact on the P500 connector for the heater!
Thanks!

Look at the manual it should show the pins at the tube / neck board. Remove
the neckboark and ohm the tube directly.

Hi guys,
           I have a G05-805 that everything is currently working on it
except; I now have no neck glow. ;-( I have checked to make sure I have
6.3 AC power on the connector going to the monitor and my actual cabinet was
showing me 7.2 Volts AC on pins 9 and 12 of the monitor connector. I also
replaced all the fuses in my rectifier block; recently. All fuses show good
with no resistances. I might also add that I just replaced all electrolytic
capacitors through out the entire cabinet from the rectifier through the
main board and monitor. I was just doing the usual preventative
maintenance; once I was done with this process; the game was running great
and the picture was fantastic. Then I let it burn in for about 7 or 8 hours
and we lost neck glow. We still have deflection chatter, high voltage
(right at 12K) and spot killer is currently off.

I even took this monitor to my other known good working Asteroids deluxe
cabinet just to narrow this down to this specific monitor.

So here is my question: To verify that the heater has actually opened on
the CRT I would just need to do an ohm reading across pins 9 and 12 on the
back of the monitor's main connector. This is currently showing open. How
can I do this same test bypassing the deflection board doing it straight on
the tube? I have a bad feeling that my heater has just gone bad on me and I
will be in need of a replacement tube.

Thanks,
Ed
