Title: Cleaning back of CRT monitor Post by: PLUNGER BOY on September 27, 2011, 11:10:54 PM Just got a game king and monster mansion i game . After cleaning all that i could reach inside and out . I slid out the monitor and its pretty dusty back there . Can i blow this area out with air and be safe of damage to the machine . I see the high voltage warning on the tube :50- :50- :50-. I don't care about me I will heal :47-. i just don't want to go of the way of non washable reel strips like i did when i first started with the reel games :25- :25- THANKS for any help

expose any of the heavily insulated red wire going from flyback transformer to the side of the tube you should be ok. a vacuum cleaner can also be used with a vacuum attachment do not touch the monitor chassis with the metal hose end. The High Voltage is stored in the caps and between the anode and cathode of the tube. Anode is on he inside of the tube, the red wire going to the side The cathode is on the outside creating a very large capacitor that carries 20-40 thousand volts IT is enough to kill you. You can also use electronic component cleaner and spray board just do not try to use a towel to help scrub anything, less of the components you touch less likely you will get a dangerous shock.

Title: Re: Cleaning back of CRT monitor Post by: Buzz on September 28, 2011, 12:55:54 AM Modern day monitors are self discharging when the power is turned off. If it was possible to get killed by a monitor I would be long gone !!!!!!!!!!!!!!! Oh and don't get the idea that if you break one it will blow up. Old ones I hit the neck with a small sledge hammer, slight hiss and then I beat the crap out of it !!!!!!!!!! ( Cut my thumb once )

Discharges damn near immediately if there's anything there to discharge.
