i accuired a good crt monitor that has power button pushed in and i plan on opening it to see if i can fix this. I know monitors can be dangerous if they are opened and you dont let the tub charge disapate over time. My question is how long must i wait before i open the thing and fix the button. its been 9 days so far

I never recommend anyone doing their own CRT repairs; better off letting a qualified technician do them.

But FYI, a CRT charge can remain for a long time, even after several days in a low humidity environment. It's Winter and I assume you have been heating your house...probably fairly dry air....nice environment to build up static and/or preserve charges. Better to humidify the air to help slowly dissipate a charge.

NEVER wear a static strap when working on a CRT; not unless you want to light up like a Christmas tree. PC case, yes...CRT, no.

In truth, though it's possible for the CRT to maintain a healthy charge, it's not that dangerous to work on a video monitor. I started working with them as a kid in a TV Repair shop, and I got bit lots of times with the charge, and I'm still typing this. :)

The proper method of discharging the tube is to use a well insulated probe that is grounded to the chassis and slide it under the anode clamp on the side of the tube to discharge it. Most modern monitors/TVs have a bleeder path that will discharge the tube anyway. If you stay away from the high voltage section, you should be fine.

Well, your a braver lad then I!

I wouldn't open a monitor for the life of me, I also have a light switch that needs to be replaced, but I am too afraid of killng myself even after throwing the breaker...

Gee, I guess working for several years in a TV shop when I was in HS cured me of worrying about the high voltage in a TV or monitor. It's really not that difficult to keep out of trouble in there, honest. :D

I dont think it is as much a problem being careful as it is a problem with oooops. Like if you are in there, and you drop something even if not in the monitor, dont grab to fetch it! That is usually when the bite happens, and though most often not a fatal bite, It sure does hurt like the dickens!

The damage usually comes from jerking your hand away and slashing it on something inside the chassis. Don't ask me how I know this. :eek: ;)
