oh and if you do send off the chassis, dont play around with 30,000 volts.
i see a lot of suggestions to use a screwdriver with a wire attached.
best bet is to look for some electronic surplus on ebay and get a lovingly used 40,000 volt probe.
my favorite thing about a probe is that it sucks all the juice out of the tube and chassis without the scary cracks and pops of a screwdriver that ive heard about.
ive never used the screwdriver cause many years ago i had to buy a probe for electronics class.
connect the ground clamp to the mental frame of the monitor and make sure its a good connection, plug the banana into your multimeter, set it to 20v dc
and stick that probe under the anode cap making sure you touch the prong, your meter should read 1, 2, etc for a second or two. dont be fooled. 1,2,3, etc is ten thousand not 1 volt. wait 5 minutes, do it again, wait 5, do it again.
as a last precaution, put on a rubber glove before you pull the anode. rock it back and forth till it pops out, and then touch the anode to the metal frame of the monitor just to be sure.
okay, your there. disassemble the boards very carefully, make sure you are ultra careful when you pull the neck board. do not pull it at an angle of any sort. Its extremely easy to break a pin, or worse, crack the glass on the neck. if it happens you might as well throw the whole thing in the trash.
anyways, this is if you decide to repair the monitor thats there.
you never want to send a whole monitor out for repair. that tube is damn fragile, and heavy. they will charge you a fortune for shipping, and theirs no guarantee at all that it will arrive unbroken. shipping is just like any other business. even if you stick fragile all over the box,
if your package happens to arrive at a terminal 10 minutes before that worker goes home and the boss says youve got to process 5 more packages, all of them will get tossed around as fast as possible so the guy can go home, trust me.
