Title: monitor chassis removal
Post by: billge1 on June 07, 2005, 01:36:10 pm
Probably an easy question for all you guys but thought I should ask anyway so I dont get zapped or blow the monitor.  Should I remove the monitor chassis from the monitor and remove all the excess charge if Im just going to be changing a pigtail fuse?  Its a wells gardner 25k5515.  I think that this is the only problem with it and thought I should try.  Thanks for all the help.

You don't need to discharge the tube (unless you cant replace the fuse without removing the chassis+anode wire, which then of course you need to discharge the tube) but you certainly better check to see if the large filter capacitors on the chassis still have a charge (typical if a fuse is blown and it has recently been plugged in to test.

The simple test it to take a multi-meter and test both sides of the fuse when set on 200 VAC.  Is there any voltage across the blown fuse? If so, you can bet there is a charged capacitor somewhere. If not, then double check voltages across the larger capacitors, and if not, then it's safe to work to desolder and replace the fuse.
