Help me

I would try to reset to factory settings first see if that does the trick these are specific instructions for a pavilion vf52 lcd, i imagine they are the same across the board....try it and see how you get on
Adjusting the Factory Recall To recall factory settings back you should follow the steps below: 1 Bring-up the OSD “Main Menu”. 2 Use the ‘+’ or ‘—’ button to move (forward or backward) to the factory recall icon and highlight it. 3 Press the ‘Select’ button to activate the factory recall action.
hope this helps, let me know if i can be of further help
