hi! i have an Ilyama LCD monitor 23"~ @ 1080p that is having some problems, the LED lights up blue indicating that it is getting the signal from the pc alright, but the LCD screen itself is off and occasionally flickers on for half a second or so then immediately goes totally black again, i did buy the unit from OCUK and it should still be well within warranty, but id rather not have to go through the hassle!
