My lg flatron w1943 constantly flickering. i replaced capictor 1000mfd 25v, 220 mfd 16v but problem presist. plz give me right solution
Hello,
Two things, First you need to replace all of the capacitors on the power supply board at the same time even if they do not show signs of failure because they have been under stress. Secondly, you need to use the correct ratings on the capacitors not just the mfd and voltage. Parts from Radio Shack and such will not work right and can cause additional damage to the power supply board. Here is a link to an article about getting the correct capacitors for LCD monitor repairs.

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!

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
