HP W1858 monitor

Hello,

So now i have a hp W1858 monitor i have had for a few years now the other day i turn it on and i have an OSD lockout which puzzled me i have now been unabled to fix this for 3 days now using all the info i have found online as i will list the options i have tried now

1. reset to factory options - no help
2. hard reboot monitor (unplug hold power button) - no help
3. check the buttons to see if they are stuck ( none was stuck as far as i could hear) - no help
4. open the monitor and remove the menu buttons ( to make damn sure no buttons are stuck) - no help (everything still happens including the menu chosing stuff on its own)
5. check cables, wires, and all the circuit routes - no help ( everything looks clean and good)
6. pluging it up to another computer - no help
7. jump kick the damn thing out the door - have yet to do this yet as it was the last option i have

any help would be welcome any questions plz just ask i will try to answer any i can.
