Title: Monitor Discharging Problem?
Post by: null on November 15, 2003, 08:28:29 pm

I was trying to discharge a Wells-Gardner 19k4921 19" arcade monitor with the alligator clips on the ends of heavy gauge speaker wire with screwdrivers in the clips. I used the ground port on a electrical outlet as the ground. When I slipped the screwdriver under the suction cup on the back of the monitor I didn't hear a sound, I did this a few times and was wondering if it would be safe to take out now and/or possibly that this type of monitor is self-discharging?

Thanks in advance,

Hallie

Ok STOP!!!  You're monitor is likely not discharged!!!  You have to ground the tube to its internal ground and not an external one.  Think of the tube as a large capacitor you have to short across the terminals to discharge it.  What you did would be equivalent to going next door and grounding to their outlet--i.e. no effect whatsoever on the charge in your tube!!  

You have to hook one end of the the aligator clips up to the monitor frame and then the other to a screwdriver which you insert under the suction cup to discharge the monitor.  keep one hand in your pocket as you do this and make sure that you don't touch ANYTHING!!!.
