Open Frame Monitor, Safety??

[lettuce]

I will be having an opened frame monitor sitting in my back room for the next few weeks and just wanted to know on how safe it is. Do i or should i be discharging it everytime i stop using it for the day. The only reason i ask is there are some pets about and dont want any of them getting a shock when its not being used, so do i need to discharge it all the time? Can you get a jolt from the anode even though the cap/suction cup is in place??

unlikely unless your pets decide they want to stick their paws in the anode,in any case most models built after 1990 have a discharge circuit built in to the flyback(unless it's a crappy chinese built monitor)

sooo... all of them? 

naw, i think you're good. unless you take to rubbing steaks or something on the monitor... most animals will give it a sniff and be like "egh, nothing worth eating here" and  be on their way.

So it's perfectly safe for me to be around the back of the monitor (with it turned off and unplugged) and be doing wire management and can even touch the anode cap/suction cup and not get a shock at all??

The chassis is a, Pentranic CGA 15khz Chassis CH-288-S26A not sure if it was built before or after 1990 though, it's brand new however, how long should it take to discharge itself if a circuit is fitted?

Also is it common for new monitors to smell of burning for a while?, had the monitor on about 5-8 times so far in short stints (10-15 mins) and I can still smell burning.

yes. the anode cup is designed to keep the charge inside the tube. you only need to worry when you are going to be poking under it or removing it.

discharge could vary between a few seconds to a few minutes. sometimes there is a small charge that remains inside the tube. not a big deal.

burning?! like ozone? (photocopier smell) or like melted plastic? (burning wires smell). you might have something going on. Are you hearing any pops or crackling while it's running? check the wires in around the chassis maybe you have a wire laying down on a hot resistor.

Nah i cant hear any popping or crackling, if i did i would of jumped for the off switch lol. Just a general electrical burning smell really

If you leave it sitting out I wouldn't worry about about stored charges. I *would* worry about the neck of the tube getting cracked/broken, so put it somewhere out of the way so it can't get bumped.

Make sure you wear good, solid shoes with rubber soles in case you aren't able to dodge the cap discharge spikes that you see around open frame tubes.

Cap discharge spikes eh? Thats a new one.....

Don't worry about discharging anything. If the tube retains a HV charge (the tube is a capacitor due to the coatings on the inside and outside of it), it stays inside the tube unless you go and yank out the 2nd anode cup/lead. Don't screw with that and yer fine. You should be careful with monitors but we don't need to be paranoid.

Prob'ly the most dangerous thing about a monitor is dropping it on a cement floor and shattering the tube. Glass will go *everywhere* in a fairly large radius. Bad mojo....
