Had a Army PC repair guy tell me that he was told that the monitors capacitor can hold a charge for 65yrs. BTW the fly-back is something you definately dont wanna touch in a monitor.
can you tell that parts are charged with a tester screwdriver (you know the one with the little red neon inside) poss use it to discharge the parts?
i've modded my psu, no problem... i put bolts on the opposite side from the fan, so it would hang outside the case...
Strange Had a cap blow on me. I was shoving all the stuff back in after a quick tidy session and before final shutting up I figured I would power up and see if all was well. It was for a minute but then - POP! I'm talking a wargames type pop here, the sort that brings to mind £ pound signs going up in smoke and underware refitting. Anyway, I thought perhaps that some cable splicing I had done wasn't insulated or similar so I pulled it all apart but could find nothing. I plugged back in all but what is basically required and powered up - it worked! Much sighs of relief at this point. I started to add one piece of kit at atime and found that my CDROM drive would not power up. I opened it up and found like a piece of cotton wadding floating about. Further back towards the power connector I found more so I unscrewed the PCB and looked under it. A whole damned capacitor had blown off the board leaving just the pins in place. A week earlier I had done the blue LED thing but it had worked a treat over the next few days. I've heard you can blow a cap by reverse wiring but this was not the case - any ideas ???? Strange!!!!!!!!!!!!!!11
aight i got 2 questions... first, where the hell do you find a 65 year old monitor to find out how long the caps in it can hold a charge (weren't monitors 65 years ago a helluva lot different than they are now???) second, if ya wanted to take apart your monitor to paint it, would it be ok??? or how would you go about painting your monitor? i woulda started a thread to ask this question in the modding section, but since you guys were talking about monitors, i figured i'd ask here instead of crowd the forums with more threads... :dude:
If you take a monitor apart then dont touch the HT lead, the thick black wire that attracts tons of dust! Touch it and bang you could wake up dead, stores about 25KV (25000v) Also maths can be used to work out the 65 years bit!
Welcome to the forums m8! But how do you wake up dead? If you're dead then you don't wake up, unless you mean in the afterlife!
a little googling came up with this site http://www.elextronika.com/electronics/f_tv_rep.htm#TVREPAIR_003 should give you a fairly good idea about discharging capacitors
