Hi guys The small white light on my 20" ACD is flashing (short-short-long) repeatedly and it only comes on for more than 4 secs at a time every 1/10 attempts. Once past this it works fine, although perhaps a little less bright than my 17" Studio display as the brightness controls on the right of the display appear not be working now either. I guess it's a backlight problem. Has anyone had the same symptoms? How did they rectify it? How much did it cost? Any help greatly appreciated.
