    Do you know for sure that your computer is booting up and that it has video? Monitor might be good. Try another monitor to make sure that your computer is booting up.

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, has power
so this a problem with the VGA card in the moniter. The part number you require are Manufacturer Part Number EBU59489401
Board Numbers 791501300700R
google/ebay give a selection.
The w2234s is one of the easiest to dissassemble with no screws holding the outer casing. I have swapped the VGA card and fix this on 3 W2234s, all less than 3 years old. No faulty caps. Others took 20mins+ before going loopy (on/off continously) some less than 3 sec.

    It's the monitor not the OS or the PC. To verify this you would test the monitor on a different PC. If it continues to blink it's the monitor....Think about it!

My LGFlatron W2234S won't come on and instread the power light just flashes. Can you tell me what to do?


the blinking light of the power led means that the start voltage was not working properly, if you are a trained tech you can repair this monitor, but if you are a simple user it's dangerous, there is high voltage inside. cause of blinking light :
  1. puffed capacitor on the power supply
  2. broken FBT on the inverter board
  3. broken transistor on the inverter board
solution:
  1. replace or repair the power board
  2. replace or repair the inverter

Try changing the Resolution for the lowest one, if it works it will see the letters and everything very big.

Sorry for my english.

Screen turns black and blue LED is blinking


Sounds like the monitor is being made to show a resolution it does not support. Check the available resolutions the monitor supports and then check what resolution the video card is giving, if it not compatable, you get the black and blue screens.

For the video card, right click on the desktop in a an empty area and choose properties > settings > your resolution from the card will be there. Now from there click on advanced > click on monitor and look at the monitor settings. Make sure the box is checked to hide modes the monitor cannot display. Now click on the adapter tab and click below on all modes. This is the list of all modes that both the monitor and the video card argree on. Make sure the settings in your game match one of these and you should be good to go.

Moniter transitions to LG logo


Check the cable and make sure it is plugged in securely at both the monitor and PC. If the cable is connected properly, then the problem must be in the monitor itself. You could try setting the input mode manually on the monitor - the default should be auto - you could set it to VGA or DVI whichever your case is and see if it helps.
