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

SOURCE: Power Button on (BLUElight)and goes off again. No

This is most likely the power inverter board in the monitor - this is common in many monitors. If it started taking longer and longer to display an image, and the power light is blinking on-and-off, that's most likely the problem.

You can confirm that it's actually the monitor and not your computer or the cable by plugging in another monitor if you have one to try. If it's under warranty, send it back, if not, there are inverter boards for many common models of LCD monitors2.gif that are replaceable. The board can run anywhere from $50 on up. Depending on how old your monitor is, and how much you've invested into it, you may find it better to just replace it with a gently used one from ebay.

Ahh the same thing has happened to my monitor! Mine unfortunately is 1 month over warranty. Apparently this is a common problem with this model!

Lg w2234s-bn Monitor Cycling randomly through Light View Modes/Power Button turning It's self on and off.


On and off cycleing could be caused by a bad power supply or a low battery on your remote. Check them both out. Good luck.

Hello, I have a LG flatron w2234s and a week ago the screen started to shut down on its own while i'm using the computer or when it goes to sleep mode. The screen gives me the LG sign and just turns off...


First try it on another Pc, you'll know the root of the problem. If there's no problem on another pc then the problem would be with your video card/motherboard. If the problem is still the same on another Pc, then your monitor has internal problem. You better call up a technician, he/she will check it for you, must be Pcb problem. Good luck. Thanks for using FixYa.

Power swich blinging ,does not power on


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 occur 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.

Monitor restarting randomly


Rarely does a monitor go out due to drivers. Try another monitor and verify that it isn't the computer (it isn't). If the power light goes out it is the power supply (usually inside) the monitor. If the light stays on, it will most likely be the backlight power unit. Browse the internet for the model and parts. Newer units are difficult to find.
