I've thought about this situation and tried to apply some logic to it, but I know that logic doesn't always take account of everything since it's easy to make an error and miss some vital fact one had not considered. But I've never seen static damage failure on anything (yet).
I do think these 'myths' that circulate may have had some basis in fact at some stage, but are propagated through the decades with few people applying much rational thought to them or taking a chance to test things out. Most people don't bother experimenting, which is curious really, as that's the way you find out what happens in real life and build your experience. I know it's risky to experiment with something that's worth a lot of money. Sometimes I just feel risky!
I've used a vacuum cleaner for cleaning out the inside of computers on a few occasions - while avoiding extreme suction - gentle application only is all that is required to move the dust in the direction you want it to go, to safely ensconce it in the vacuum bag as opposed to being blown around into the room, possibly with the help of a little soft brush to tease it out. The amount of vacuum required to move the dust out is very low, you don't need a lot of it, so I use an extension plastic tube loosely connected with the air bleed open and vacuum on low setting.
I remember seeing the insides of our TV at home in the 60s or the radiogram with its big valves et cetera. There was quite a lot of dust there but it didn't seem to make a blind bit of difference, it still kept on going! I suppose it could have been a fire risk if there had been an ignition source, but that doesn't happen even with a valve machine. The hot bits are sealed inside glass. Or perhaps clumps of dust could promote electrostatic leakage or even discharge, particularly apparent around the ultra high tension anode to a cathode ray tube. Those TVs keep working though and don't catch fire, at least I've never seen it happen.Statistics: Posted by Leewave — Mon Oct 02, 2017 11:20 am
