The monitor is probably on protection.

To start unplug monitor from power and from computer and test computer with different monitor to find out if it is monitor or computer fault.

If it is computer fault and no video signal , then test:

  • Video cable.
  • Video adapter on PC (sometimes integrated on motherboard)
  • Motherboard.

If it is monitor fault , then the monitor is on protection.

When on protection you keep having a flashing led on front of the monitor , and monitor turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the Monitor goes on protection there are only two possible causes.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or a broken contact, identified an internal fault and kicked in , starting the flashing light.


If you are in situation one, then the monitor will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occurr are a blown capacitor on power board, faulty inverter board, faulty input board, or a fault on LCD Digital Controller board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.

Try moving the video cable, and if the cable is not built in, then also try a replacement cable.

If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

I had a similar post about an LG 505G. Just bought a new LCD monitor and decided to open the monitor before putting it on permanent storage. I noticed a bloated capacitor in the control board just adjacent to the low voltage power supply. It was a 1,000 mFd 10V cap. So what the heck I desoldered it and replaced it with a spare 50V capacitor of the same rating I had lying around. I assembled the unit plugged it in and VOILA!!! the monitor was working again. Hope this helps.

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.

SINGLE VERTICAL LINE IN MY LG LED TV


A single line indicates a failure in one of the hundreds of connections on the back of the LED display panel. It normally cannot be repaired, but can be replaced. It may be more cost-effective to replace the unit.

Lg driver download


If you're talking about using an LG TV as a computer monitor, the generic display driver will suffice. I've never seen any noticeable improvement on display or features when Windows displays the monitor correctly or as a generic. If your resolution is too low and you couldn't increase it, the problem is likely your resolution setting or video card driver, not your monitor driver.

I HAVE A LG FLATRON M197WA LCD TV MONITOR . HOW I CAN OPEN BOTH TV AND PC AT A TIME ? HOW I ADJUST THE MONITOR TO VIEW BOTH IN A SINGLE WINDOW? 0919830151045


You can't. The TV can't operate as both a monitor and a TV receiver at once. In order to use the TV as a computer monitor you need to select the VGA input, which shuts off the TV tuner. If you want to watch TV at the same time, you need a TV tuner card in the computer. Then you can have the TV program displayed in one window while another displays whatever other application you're running.

It means your PC video output resolution is too high for the LG monitor to display (your old monitor (CRT) can handle higher resolution than this LG LCD monitor), you need to set the PC video resolution to native resolutionof this monitor which is 1280 x 1024 @60Hz. You may have to use the old monitor (CRT) to set the resolution to 1280 x 1024@60Hz, then hook up the LCD monitor.

I have just connected my Dell Pc with a new Nvdia 8600 graphics card that can go up to 2056 X1280 in resolution. But my LG M228WA seem not to go over 1680 x 1280 preset resolution. It can go up to 1950 x...


As fars as the specs go the monitor has a Max resolution of 1680×1050. That would look like the bottle neck. Either you'll have to just make do with the max of the monitor or you'll have to get a new monitor that supports the size you want. Hope this helps. M~
