discharging 101

[JGevaryahu]

I suggest using a resistor in series with the discharger wire, 1MOhm-10MOhm, 2W or so, otherwise the extreme charge change on the deposited anode inside the tube can cause it to delaminate, ruining the tube.

Thanx for showing. I joined utube cuz of this video.

I wouldn't touch even the rubbr cap, just stick the driver under it

This guy knows his stuff and his music... cheers P- 5 stars.

I just grab a hold of that big red wire with one hand, while touching the chassis with my other hand. The shock is pretty gnarly.

Video was very helpful. Worked like a champ. Thanks.

Great vid. My old Commodore monitor is starting to go, and I'll probably have to replace some caps, so knowing this is important.

[katananja]

You know that are stupid people all over the place, don't forget one important thing, remove the device from the mains before discharge the tube.

Good video but I would never even lay my hand on that suction cub. 20 year old games means that rubber cup is dry and can be cracked. Doesn't take much for 45,000 volts to find a path. :(

just wanted to thank you for uploading this video... I am too impatient for my own good when it comes to safety and after reading a few text tutorials on how to do this I was about to skip the discharging phase of my project due to the steps involved being to confusing... After watching your movie I've just successfully done the first discharge resulting in three loud satisfying snaps and I am now waiting to do it again second time for added safety. Well done.

very nice video and it is also VERY good that you took the right percautions on discharging it if you don't that it could be faatal :(

Thank you very much also. Just got past stage one in discharging (will do it a few times).

I was about to throw out my TV and spend up big on an LCD or Plasma set. Thought I'd open it up first and found a resistor sitting in the bottom of the case. Still have to find out where it came from, and it being de-soldered from heat doesn't bode very well anyway...

I have to take issue with the hand peeling-back of the suction cup. I've discharged monitors dozens (hundreds?) of times and have never had a problem simply slipping a screwdriver underneath the cup. Often they spark when the edge of the suction cup has just barely been penetrated, long before the screwdriver touches the clip -- you don't want that to happen to your hand.

Honestly I can't remember as I made the video some time ago but, I seem so remember saying that I usually do not pull back the anode cap but for the sake of the video and so folks watching could possibly get a better look, I decided to pull it back. If this is misleading to anyone I appologize. I usually just slip the screw driver under without touching the anode cap with my hand at all. Yes you should always use caution when dealing with potential high voltages.

About time someone does one video about it!

thanks on behalf of every arcade fans

[blackhawksfan54]

Thanks a lot for the vid!!!

But always one thing seems to be lacking in text posts, faq's etc...

Where does all that electricity go? I would assume a path of 'least resistance' means downward and through an electrical outlet. It doesn't just dissipate into a chassis I would guess.

Therefore - the game plugged IS into the wall? yes or no?

No one ever mentions that one... yet it seems quite important?

[beatonrj]

I was wondering the exact same thing. Anyone?

[hayabusafmw]

good question :blackhawk i want to know also

i have a other question: are you sure you can touch the suction cup without getting zapped?...

i heard many story of people just barely toutching it & getting a nasty shock.

[bobbyconover]

It actually does just dissipate into the chassis. Seems strange, but it's how it works -- this is why you're able to discharge a monitor separate from a game (say, on a test bench). The game doesn't need to be plugged in for a good discharge to take place.

[TortureBot]

Wondering same thing, too. And no clear answer from author of the vid??? What about it p1899m??? I would think the cord would have to be plugged into ground to have the frame or chassis properly grounded to dissipate all that voltage, but who would want to work on something plugged into a receptacle? Does the chassis REALLY dissipate the HUGE charge? WOW?

[patdanis]

Rule number 2. Discharge the monitor again before reconnecting the anode cap. The tube can build up the charge again that you waited 5 minutes for to discharge again. Not all monitors will have a charge on them. Monitors that have been unpowered CAN (but not always) have no charge on the tube. Also, many monitors automatically discharge when you power them down but don't count on it. ALWAYS check.

Extremely useful. Been looking for something like that online for a long time. Thanks!
