Hi,
Two parts to check are the VGA and the power module (inverter). Using a voltmeter across pins 1 and 3 of the VGA see if +5v(can see when back opened) . If no +5v, need a new power module, search ebay for similar 22" LCD inverter new from china and refit for about $20 4 lamp with ac power, Else its the VGA ,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, $50

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.

Doese not want 2 go on !!


Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, blown fuses, poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed LG and other monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

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
