Question about HP Compaq WF1907 Monitor
The OSD (on screen display) is a lock feature that locks out all access to the control functions. Basically you can use this feature to lock the access to the control functions once you have everything set the way you want it so no one will be able to adjust them without unlocking it. To learn more about this option you can review this lcd monitor manual to learn about the details that your monitor might have (this may or may not be a manual for your specific monitor, but I am using it so you will get an idea about the different features some monitors might have. Yours may or may not have all these features). I hope this helps answer your question. If you need further assistance, I will be more than happy to answer any of your questions or help you. Have a good day.
If you would please rate my help, I really would appreciate it. Thanks

I know how to fix this, but it involves opening up the monitor....
First unplug the monitor and get all the cables out. Then get the monitor of its monitor stand, this is done by unscrewing the four screws at the back of the monitor stand.
Now you can pry open the case with a flat screwdriver. On the inside you see a small electronic board with the power switch and the other switches on it. These 'broken' or dirty switches are what causing the OSD lockout.
Get the small board out of it's bracket and use some ETHANOL or ALCOHOL (atleast 70% pure) to clean the switches, you just spray or drip the ethanol into/onto the switches. This will clean the switches of any grease residu. Then spray the switches with air out of an airspray can untill they are totally dry.
Now you can put everything together and voila! it is working again!! atleast it worked for me :):)
This fix will only work if the switches aren't broken but only dirty or a little bit stuck, if they are broken then you would have to solder new ones on the electronic switch board.

this could be a bad button connection or the osd IC chip is failing for some reason that would need to be tested to determine why.
so if you can take it apart then clean the button and the plastic of dirt , and check the contact button to see if it looks faulty or check it to see if it is making contact all the time
if those are not the problem then it is the IC chip and will need testing to find the culprit
