Fixing a dying power supply...

Sid on the Hacks site writes up a good simple how to/tip - "My LCD display wouldn't come on, it would just flicker. The LED on its external power supply was steady on when it wasn't plugged into the monitor. When I did plug it in, the LED blinked at the rate of 2x per second. Measuring the power coming out of this supply using my multimeter, I saw that the power level wasn't steady -- it was pulsing slightly (about 2x per second). This was while unplugged from the monitor. Found a new power supply on eBay, and now everything's fine." Link. On a related note, the RSS feed on hacks site is awesome.

often, the problem with these things is the cord or a fuse. Since in this case, power is getting through to the circuit, it's most likely to be a capacitor. It would be interesting to find out what went wrong in this ps. Buying a new one is no fun.

Hey, I did the same thing yesterday! My computer's power supply was broken, so I fixed it by using one from another computer. A MIRACLE OF SCIENCE AND TECHNOLOGY!I should see if I can repair the broken power supply, because even though a new one is only $20 (or cheaper if you look harder, I'm lazy and that was the first one I found) I feel like I need to counteract the extreme retardivity of this "article".
