SOURCE: monitor light blinking

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 statebecause 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.

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

Hi sophie,

I see you want to extend you monito to an LG external monitor.

Have you tried selecting the input PC or the input that is for the cable that you are using for the Video.

If you are using HDMI select the Input HDMI on your LG if you are using DVI then you should select the input DVI to be able to get the signal from the Laptop come out of your LG.

I hope this helps.

Have a nice day,
