Re: 19V2000 blowing F101 and F102

Thanks, Rodger.  I just found out why it appears this way.  Originally, there was a blue filter over the monitor that apparently eliminated (or significantly reduced) this glow.  Mine has the cardboard bezel but, no filter.  Personally, I prefer the white image so maybe I'll try just a neutral density filter of some type if it bothers me enough. The bulb is definitely a black light bulb as my white T-shirt glowed bluish while I was futzing around in there. ________________________________ From: Rodger Boots <rlboots2@gmail.com> To: vectorlist@vectorlist.org Sent: Thu, November 10, 2011 2:02:15 PM Subject: Re: VECTOR: 19V2000 blowing F101 and F102 Make sure fluorescent bulb that lights the background is a "blacklight blue" bulb (will appear as black with power off, faint purplish when lit).

HV diodes and their connections can lead to interesting things happening with the HV cages. A bad connection to the diode or failing diode can generate a surprising amount of heat - enough to char the rubber shield(s) on the connector!
