Ha - I was looking for tips on my current monitor, but as it happens I have that exact monitor sitting in my basement (and it died in much the same way). I don't know how to do circuit repairs exactly, but those were good tips (re: capacitors). Thank you!
Use a higher Voltage value for the one that vented. Doing so should stop the problem from happening again so that any voltage spike wont vent it again.
ive been looking at some random circuit boards lately, and I wonder why is it that what they all have in common is that they have a lot of capacitors on them? I understand why they have a lot of IC chips, but i always see a bunch of capacitors. Is it necessary?
@shadowhand56 Capacitors are you for two major uses, one is as a filter to clean the signal or remove interference the other is to time, manipulate the signal. Eg if you wanted the monitor to turn on each back light with a second delay you can use a resistor and a capacitor connected to a transistor base which means the transistor wont conduct until the capacitor reaches X charge.
Mike - a man of many talents. I used to be a camcorder repairman and I have replaced very many electrolytic caps in the past - especially the small silver ones. For circuits that run hot and/or being used in hot environments - go for the 105 degree type. It is satisfying to fix things isn't it? Good tutorial.
@alanstarkie2001 Indeed. I like salvaging things that seem doomed. Curiously, as you mention camcorders, I'm gonna try to fix the Sony. And I'll film it with the Xacti.

Thanks for the video - Found my bad capacitor and fixed my monitor :) saved a bunch my first time

It is good video that can identify the faulty capacitors. Thanks

very good tutorial.
What is the software that you are using to capture and edit this video?
thanks

I have a Dell 15" FPC monitor that the power button keeps blinking on and off I checked the power board caps and they look ok any suggestions?

@shadowhand56 It must be, they're still on everything. I don't know a whole lot about engineering the board.

@shadowhand56 i think the reason why they use capacitors is coz they can hold and release power quickly thats why i think maybe lol

I had to fix my Q7 that way, but it was just one 25 uf cap
