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.

SOURCE: No picture lg flatron w2234s blinking blue light

Hi My screen developed exactly the same problem. It appears to be a hardwear problem associated with the screen it's self. continuity test is ok on the lead so I took it back to the shop under warranty and hey presto, the replacement works. I don't know what the problem is but there are a number of other folks on another thread with the same problem and their entries are dated May 09 too.  Dave

I think that two capacitors in the powers supply circuitry(incise the monitor) has gone bad. Just open and you'll see them.
This should solve your problem.Best of Luck.Please rank me appropriately. If you want any clarification, Please get back to me

I need the drivers of flatron w1943tb....


LG Flatron L1515S doesn't need a driver to be installed on Windows Computer or any other systems. If you have problem with it, then it should be your graphics driver that you would need to install.
Similarly W1943TB-PF doesn't need driver. (I am not sure which one among the two LG Flatrons you have since your question is tagged under the LG Flatron L1515S while your problem refers to LG Flatron W1943TB.
If you have other problem, let me know with more details.
Good Luck.
Thanks for using FixYa.

LG Flatron l1515s which is giving Out of Range 64.0kHz / 60Hz and can not even give setup menu. Please help.


This is not a setting on your monitor. It is a setting on your operating system. The display settings needs to be set to a 60Hz refresh rate.

Hook up your old monitor and right click on desktop --> properties --> and then to display and advanced settings. You can then set it to proper refresh rate and plug the new monitor in.
