I have had this monitor for a little over a year. (ProView PL2230WDB 22" LCD) The problem started out with white screening on computer boot up. Now the power light just flashes on and off, always blue never green. It continues to do this even when disconnected from the PC. Turning off or unplugging and re-powering it changes nothing. But when connected to PC and the PC is turned on you cannot turn the monitor off, the power light just keeps flashing blue.

grybicki, Sounds like "switch-mode-power-supply/ccfl inverter supply" problem. Is pl2230wdb "black" or is it "blank n black". Yes, it can be both or just "black". Do some reading in my fixya profile to understand your options that you have open to you. Your ccfl back-lit lcd display no different than any other brand in it's basic design and operation. Use warranty if possible! (you didn't state date of manufacture) Could be a failed solder joint (open circuit) or bad capacitors on "smps/inverter" board. First, do a lot of reading before making decision on fixing or trading up. Good luck with repair. Let us know what you will do after you do some reading. Reading is free!!! 12fixlouie
A flashing power light like that indicated a blown power supply. Your monitor should be under warranty with Samsung. Check the mfg date on the back sticker, if it is less than 3 years then contact Samsung. If it is out of warranty then contact us at email@example.com and we can get you the info you need to do the repair yourself.
try test the LCD to other PC, if it is working on other PCs, then your
VGA card might be the cause. And if the same problem happens to other
PC's then the LCD is at fault. Remember to Check the VGA cord. Good
Same problem, and solution 1 given here fixed my Proview 900W. A few of the 470uF caps on the power board were oozing dielectric probably due to overheating. Hopefully the replacements will hang in there for a couple more years...
