    Sounds like the monitor is bad. Does it also do this when you first turn on the computer and its booting up?

Hi,
The problem is the VGA part of the moniter is playing up. Two areas, one the MCU on the vga card, the other is a faulty transistor on the vga card. Repairs on a PCB VGA circuit are impossible with out the right tools.
The part number you require are Manufacturer Part Number EBU59489401
Board Numbers 791501300700R
For a replacement card
if no warrenty
Some thimes the 5 sec can be 20 to 30mins.

My LG FLATRON W2234S monitor won't turn on. When I press the on/off button it lights blue for like 5 seconds and then it goes black again. Plugging the main power cabel in and out won't work. All help...


Try changing the Resolution for the lowest one, if it works it will see the letters and everything very big. I have same trouble, specially since I change the original Vista Starter for the new Windows 7, I have not found a free controler that helps me and I have seen many people with same the problem. Sorry for my english.

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.

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 am going to suggest if it's only 3 months old you should take it back to where you bought it. Mine quit working right a few weeks after I bought it and they gave me a new one. Be sure you take your receipt with you. Even new things can mess up.

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.
