Repair a LG L2000C Monitor

As I mention in my previous post I now have 3 broken monitor that should be easy to fix.

Two of the monitors are a LG L2000C monitors. They have a resolution of 1600x1200 and are using a IPS panel with good viewing angle. That makes them very good for the edge locations in a multi monitor setup.

Opening the monitor was very easy. You just need to be careful when bending up the main cover.

After that it is just a couple of screws to remove the inner cover.

The power supply board is the one to the left.

And my suspicion about bad capacitors was right. As you might see in the picture below the capacitors are a little bulky. It might be a bit hard to see it in the image below. But the top part of the capacitors should be flat. A capacitor that bulk out is not good.

So I now just had to order some new once.
There are 2 1000uF16V ,1 1000uF25V and 2 680uF25V that need to be replaced and since I got two monitor I need to order for two. Since both monitors behave the same I assume that it is the same issue with them. The new components cost me around 25 SEK per screen ( That is around $3,80 USD ). So not very much, Actually the shipping and handling was more expansive then the components.

To be able to replace the capacitors I need to removed the entire power supply board and removed all of the bad capacitors.

I then soldered the new capacitors to the board and it now look a lot better.
Make sure you insert the new capacitors in the correct direction. You will see a marking on one side of them. Make sure the new capacitors are inserted in the same position. Or it will not work.

After putting everything back together the big moment was there. Would the monitor start ?
I connected the power and press the power button. And I got the monitors boot screen. No more blinking of the power led.It is working.
After I fixed this monitor, I then fixed the my other L2000C monitor and it also worked.

So now both of them are working. And it only cost me around 120 SEK to fix both of them (That price include both the components and the shipping cost ). 120 SEK is around 18 USD (2012-09-28).

Now I only had one 24" monitor left to fix.


  1. Thank you so much for this thorough walkthrough!

    I had an L2000C die in exactly the same way, and thanks to your excellent information, it is now back from the dead at a cost of ~200 DKK. (I was even able to order the new caps before removing the old ones. Thanks!)

  2. A real advantage of edge-lit LED technology over any behind-the-screen backlighting is that you can create screens that are considerably thinner and lighter. Desktopcon's 240hz monitor

  3. Few years ago manufacturers started to produce LED monitors and during that time they were also pretty much expensive. Click here
