Hello,

The flickering is caused by parts called capacitors in the power supply failing. These parts help filter the power supply and when they start to fail they allow voltage fluctuations to pass through and this causes the flickering. If you can solder then you should be able to do the repair yourself. We have several guide posted on our web site at: www.ccl-la.com look in the monitor repair section. Open your monitor and replace all of the capacitors that have bulging tops and you should be bak going again. If you have any questions contact us through our web site.

I hope this helps, if so please rate our solution.

From the information desribed, this means that your CRT monitor is going dead. Unfortuntly, there is no way to stop the flickering unless the monitor was replaced. I hope this has helped

Lg flatron screen keeps flickering, if i switch it off and on its fine then its starts again.


sounds like a capacitor in the power supply is going. Check caps and look for bulged or leaking component. Most new devices have non filled caps so you may not be able to judge these by a visual check.

A few months ago my LG Flatron L1900R monitor started flickering when I boot up my computer. It has become worse, to the point where it now flickers constantly.

Your monitor supports a maximum resolution of 1280 x 1024. If windows fails to give you the option of changing to this resolution and those below it then please follow these suggestions:

Update your video card drivers, if you don't know the manufacturer of your video card try windows update.

Install the latest drivers for your monitor as well.

When i turn my computer on the monitor flickers for a second then just goes black. at the start i can see the desktop but after that it goes black lg flatron l1718s


You may have problem in the power supply, common causes are the bad capacitors (bulging top/seal, or leaking). That will be the first place to check. I will assume that you have already try it with another PC and it still does not work. See pictures here for a guide so you know what to look for inside:

LG flatron L1970 h monitor flickers.


Just fixed mine :)

Biggest mistake was to try to open the monitor itself :( But I didn't brake anything :D

You just have to gently open the transformer unit (power brick) and replace two identical 1000uF 16V capacitors.
Here's how:
Remove the power cord first, to discharge the capacitors to avoid any nasty shocks when inside. Remove two rubber feet on the bottom side of the power brick. Just use your nail and lift them. Put them safely for later assembling. Unscrew two screws you just found under the removed feet. Now you have to unlock the other side held together by plastic locks. Try to apply pushing force and toque with screwdriver just where the seam is meeting the power cord socket's edge. Look for two identical capacitors and check if the tops are bulged of broken. I assume they are but you can try this method anyway. When the unit is disassembled you'll have to unsolder at least one of the wires that hold shielding plate on the bottom of the circuit board. Then unsolder the two capacitors (1000uF 16V). Replace them with the same type (1000uF) and the closest voltage possible. I have replaced mine with 1000uF 24V ones and so far I'm typing :D
That's it. If you have done this and looked for other damaged capacitors and replaced them also... Well then good luck disassembling the monitor unit and checking on inverter and lamps ;)

Cheers!
