Hey guys,
sorry, I cannot provide a make or type of my monitor because it is still built in the cabinet and I dont want to take it out because I fear of the charge.
A TV-technican told that the charge of a tube is gone after 3 days, so if I wait for a week I got nothing to fear.
Can you guys confirm that?
The cab is since 2 weeks here and I never plugged it in. The guy I have bought it from did not use it since it does not work.
He told me isīnt used for the last 2 years due to that.
So can I assume that the charge is gone meanwhile?
-
unless u are taking the chassic out by itself ? and not the tube with it
u are ok..just DO NOT TOUCH THE HIGH VOLTAGE LEAD..
un-hook power leads/rgb-syc ground inputs
remove monitor,complete in its steal case

Thanks so far for the answer, what I did not understand is do I run a risk to touch the high-voltage-lead only if I dismantle the monitor/chassis-unit or also if I only take the entire monitor out?
Do you have a link where I can see the high-voltage-lead?
To take out the entire monitor would help at the monitor since I replace the entire unit.
I still would like to know how long energy can be stored.....just for the info....
-
different monitors can hold HT for different amounts of time,almost all monitor built after 1995 have built in bleed resistor so they don't hold a charge at all-but not all of them
the high voltage lead goes from the flyback transfomer to the anode of tube-it has a thick wire and terminates in a rubber cap
-
OK, I have googled the flyback-transformer, the wire and the rubber-cab.
Its the rubbercab where you have to put the screwdriver under when you discharge it, right?
So when I touch the the wire, which is is isolated I still can get a shock? Or is there no risk as long as I dont remove it from the tube?
Any shock-risk on the chassis?
The Monitor is from a 85ī Hang-On....and unplugged since weeks.

as a rule new monitors :bleed offf: rather fast
the way i told u to do it is tried and true
insulated screwdriver :grounded: to the shell :metal: of the monitor
once under the anode cap..u might or night not here a fast zip
just leave it there for a few secs..the tube is then thought to :discharged:..
rem even though they do tend to self bleed,they are like a hudge cap.so best to error on the side of tried and true

1985 hang on should be a mc-2000 sega nanao monitor if i remember correctly,that will certainly hold some charge
what ed12 said is totally correct about the screwdriver,best way to do it is use a wire with a croc clip either end and then connect one croc clip to an insulated handle flat blade screwdriver and the other croc clip to the earth braid that surrounds the back of the crt
-
Thanks vor Thema Tunesien, Guys!
I know of the screwdriver-procedure, but I can't do it as long as the monitor is installed.
The Hang-On allows no room to work on the monitor as long as it is installed.
That's why I wanted to know how dangerous the monitor is, as long as it is installed?
Can the lead shock me although it is isolated, and what spots on the monitor/chassis-unit is dangerous as long as the chassis and the monitor are connected?
-
oh no you won't get shocked,just make sure you remove the power and video signal cables plus any earth then remove the entire monitor by the metal framework
the only way you would get a shock is if you were stand in bucket of water,apply power to the monitor and then stick your finger under the anode cap-so don't do that :)
-
un-hook power/video cable
un-screw or un-blot unit
just do not touch the high voltage lead..wa la..its out

Sorry, some autocorrection-mistakes are in the previous post.
So, just to make sure I understood right:
I go through the rear-door under the Monitor and remove the power and RGB / sync-cables.
Then I go infront if the cabinet, open the screws and pull then carefully the entire monitor-unit out and store it. I cannot get buzzzzzzed by the monitor-unit as long as it STILL IS a connected unit (monitor with chassis)?
-
The lead would shock me even through the isolation ?
-
just don't grab the HT lead and you will be fine
-
thats right
just un-hook power video/sync
remove monitor
just do not grap the high voltage lead
about that easy
