So Much For Avoiding Swollen Capacitors With An LED Monitor
I've been through the routine of capacitor replacement on way more than a few LCD monitors over the years for myself and friends and I figured the next one I bought would be an LED. Between the lower current draw and cooler operating temperatures it would be the first monitor I would never have to open up.
Right?
Nope.
About two weeks ago it started doing the classic bit of requiring multiple attempts to start up. You know, where you have to warm it up a bit then shut it off and start it again, pull the cable and reinsert until an image pops on the screen.
Took it apart and sure enough - four swollen capacitors so I ordered replacements. (Went from 25v to 35v and all 105c)
Back up and running in under $15.
So if you thought getting an LED monitor would cure all of your ills I can tell you it doesn't.

(34,589 posts)Could you tell if they were in a power supply? Have you checked your mains lately for voltage and noise?

(32,723 posts)I decided to add a small fan blowing on the vents at the back of the monitor to keep it cool.
On edit: Yes, they were in the power supply. They weren't even rated for temperature in a confined space.
Every monitor I have fixed with higher voltage caps has never failed. It's gotten so common that they sell cap kits on Ebay.
