Opening PSU
What should I be careful about when opening a PSU. I just want to take the fan grill off as the blades hit it when the fan spins. The PSU in itself is fine: it's just the helluva noise it makes because of the problem described above.
TIA

Safest thing to do is unplug it for a couple of days. However, in reality you would be okay as long as you don't touch or get tools near any components.

As far as your own safety goes, the only thing you would want to worry about is discharging the capacitors. On PSU's they are pretty small though, unlike the old tube television sets which had capacitors with enough charge to potentially kill you. If you know what a capacitor looks like then put a high ohm resistor across it and it will safely discharge.

Negative. Of course, if you don't know what you are doing or are afraid of it, then you should leave it alone. Observe safety procesures as indicated and it should NOT be a problem just pulling the fan grille.

Once you get the cover off you can remove the fan to the extent of the wire slack without having to touch any of the components of the power supply board. I normally put a folded piece of newspaper over the components as an additional safety measure.
A properly operating supply will have drained down in 10 or 15 seconds. Defective ones can hold charges for days. Been there, been jolted, although it was a Xerox 820 IIRC. With the label off you may be able to pop the "c" clip on the shaft and pull the fan. That would allow you to clean the bronze bushings that crud up. Takes something like a scriber point, and do it over a newspaper or something, them suckers are small and are almost impossible to find if they get away from you. |

The PSU had been unplugged for a week now. I opened, removed the fan and its grille, screwed the grille on the outside, blew the dust and removed more dust from the capacitors and the copper coils with my brush, and put the cover back again. Whole thing took about 10 min. Now we have a PSU for testing. Good thing, because we didn't have a 24 pin for testing.
Thanks all for your input. |
