Sign comes up "osd Main controls locked" then a few seconds later "osd Main controls unlocked". I can carry on working behind the signs as they flash on and off but it's really irritating! i can't find...

guest, Problem may exist internally on the units "switch-mode-power-supply/ccfl inverter supply printed circuit board. When very, very STRANGE things start to show-up on the lcd screen that shouldn't be there, the first place I as a technician would look would be the SMPS/CCFL inverter board. If your unit acts same way when connected to different pc, or if a "known good" monitor works well with your pc, then you will need to have unit serviced by a cold-cathode-fluorescent lamp back-lit lcd monitor technician! It's that or you will need to visit YOUTUBE and see if DIY repair is in your future. Do some reading in my or "buddymc" , "budmrtn" and other techs fixya profiles here on fixya for more info. Above all else, remember this!!! Your CCFL back-lit lcd monitor isn't any different than any other brand in it's basic design and operation!!! Just do some reading to understand why so many lcd monitors fail in the field. If this response has been of some use then do a return comment so all other users can read it. Bye for now. 12fixlouie

It is not th emonitor that is locked it is your PC, if you do not know the password the easiest thing to do would be to restart it

This is done by pressing and holding in the power button on your PC until the PC/Laptop shuts down and then restarting!!!
