Hello, I have a lg lcd monitor. w1941s model. when I start my computer, it work for sometime. then it goes blank showing only the LG logo. then the power button doesnot work. it hang up glowing. again

If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Take it to a repair shop.

My screen keep flickering every 2 seconds. However laptop still can function as per normal. My laptop is LG brand, R405.How can I solve it? Or should i just spend my money to get a new one?

Your #1 suspect: LCD inverter, a circuit which supplies white light to the screen.

Step 1 (this is a workaround only)
Attach a regular CRT to the monitor port on the back of your system. You'll be able to use
the computer as before using the CRT as your display rather than the system LCD display.
Reasons to do this sooner rather than later:
(a) flickering with a frequency of 2 seconds is likely to cause headache.
(b) your LCD inverter is about to die.

Step 2.
Use your computer software (you didn't mention what OS you're running), hunt up any/all
vendor-supplied video diagnostics for your system, meaning any diags that run at any of three
levels: (1) BIOS (just above hardware level), (2) MSDOS, (3) MSwindows. The diag most likely
to help will be a BIOS video diag - though its possible that all video diagnostics may pass
without detecting an impending LCD inverter failure.

Step 3: Download the manual for your motherboard & computer system (they're probably from
different companies, with different web sites - you didn't mention the make/model/BIOS version of your motherboard, on your LG R405 computer). I went to
but couldn't find any laptops manufactured by LG - they're heavy into cellular telephony, though.

LG L1730S 17" LCD Monitor

Hi Anand,

You need to check your power options settings and modify it , so that your monitor does not turn off automatically.

If you are using windows xp , go in control panel and then there would be an icon for power options , double click the power options and then you would find settings which read turn off monitor , turn off hard disk etc... select the turn off monitor to never mode or as per your convenience and you would have your problem solved.

Hope this helps.

My monitor flickers erradically.

Flickering erratically is usually a sign that the fluorescent tubes that light up the LCD are failing, or the high voltage power controller that drives the tubes is failing. Although these can be replaced at some cost and a great deal of expense, it is usually not worth it with very nice, new & larger displays selling for less than $ 150 (23" HD wide screen moitors) from even the best brands such as Samsung, Planar, LG and Viewsonic.

Flickering monitor

this problem many caused by bad inverter. If invertes not function, it won't feed back a good signal to tell mainboard that LCD backlight is working, so the mainboard turn off the display.

To fix this problem, it is need a qualify technician and inverter's part.
Send it to LG, they will not charge you expensive. LG have a great service.

May this help.
