That advice in bold above about only having to discharge a monitor to remove the anode cap is geared to people who know what they are doing. It's not for newbies. You could very easily discharge the HV circuit into yourself by touching two coincedental HV circuit components on the chassis. It's also very possible that you didn't intend to touch the anode cap but the monitor slipped while carrying it and that's what your frantic hand landed on. Or that you're moving the anode wire aside to reach the chassis connectors but don't notice the insulation cracks on the anode wire. I always advise people not to play with their monitors unless they have a passing familiarity with its layout and the HV circuit in particular. You don't have to memorize it but if you're going to reach and and grab something vicious you damn sure would be well served to know where the teeth are. It doesn't take more than a couple hours of study to figure out what you need to know and how to get that info. It is worth the time investment. |

Now whats scarry is when you put the cap back on and it keeps popping off and touching you cuz you didn't get a good seal on it. I didn't get a shock from that but it was still scarry stuff. I did get zapped from that monitor when I was adjusting the flyback with the power on to adjust the picture. The tube was only comming on when I would push on the flyback, so I pushed on it with both of my hands which made a circuit through ME, threw me in the air where I layed on the ground a good while with burns under my fingertips and a mental scar. I HATE BEING ELECTROCUTED. |

That's exactly the sort of thing I'm talking about. His defective flyback electrocuted him even though he followed the advice above by not needing to discharge unless he was touching the anode cap. BTW, the anode cap has no seal. It's just a rubber insulator that covers the conductors underneath it. It is not a suction cup. Frankly, you're damn lucky, seeing as how you gave a powered HV transformer a path directly across your heart. Think about the potential consequences of that for a minute. |

There are usually big capacitors on the boards and these can hold a pretty good charge as well. Some may view it as paranoid, but unless you have your resurrection skillz honed, it's worth a little extra precaution. I've been nailed by house current a bunch of times and it tickles compared to HV. I accidentally came in contact with the pins on the yoke board of an old monitor while it was on once. The zap burned a pinhole in my fingertip that went to the bone. It was one of the most painful injuries I had ever experienced and it hurt for a long time. I also have friend who has worked on a few thousand monitors in his lifetime (after watching his dad work on thousands more.) He always discharges them before he even thinks of doing anything with them where he might come in contact with the circuitry. And that includes carrying them without a case. Be safe and learn before doing. RandyT |

And just to say this again since I see this all the time: IT'S NOT A SUCTION CUP. IT HAS NO MECHANICAL CONNECTION TO THE TUBE BEYOND BEING PULLED AGAINST IT BY THE ANODE CONDUCTOR CLIP. IT IS A RUBBER INSULATING SHIELD TO PREVENT ARCING AWAY FROM THE HV ANODE CONNECTION. And I'm sure I'll get tooled on for saying this, but if you don't completely understand what that means, don't play with the back of your monitor until you do. Odds are too high you'll be very sorry. |
