Repair Your Electronics

Capacitors and cold or loose solder joints are the most common failure.

Step 1Caution

Beware of high voltage. Capacitors store energy. They store energy even when the power is removed. Always remove your device from power and discharge capacitors using a resistance probe. Proceed at your own risk!

Dont forget you need to match the capacitance along with the voltage : )

you can safely use a larger voltage value, but it is best to use the same. Matching type and polarity is EXTREMELY important. I got my first flat screen monitor this way, had a board full of bad capacitors. It cost $17 to replace them all, of course when you're buying the top of the line caps that's what you pay.

This wouldn't happen to have been a Viewsonic vx922 perchance? That's how I got mine to. I was soo impressed with myself after that.

Yer, turned out I couldn't rescue that benq-monitor but on the plus side I now have a lot of really cool high voltage components :D

Congratulations! Doesn't it just feel great when you do something like that? I can walk around for days amazed at myself.
Speaking of which I made a converter from 4,5v to 322v today. I feel fantastic :)

You know what? I DO feel great. now i am going to pt it into a cable converter case. i have a forum going on, i would like to hear what ideas you have for my project. http://www.instructables.com/community/my-smallest-computer-build-HELP-WANTED/
