HP ProBook 4420s display problems

[bssehra]

Hi

I am using a HP ProBook 4420s and having problems with the display.

On power up the display is shaded by a green/yellow overscreen which eventually disappears when operational.

And from last few days its now showing up at all (Does shows somtimes though). Just a grey/black lighted background.

The display is perfect when used with my LED TV as the monitor via HDMI port.

Any help/ideas what's wrong with it?

Thanks

Seems like something is broken with the HP laptop display, contact HP technician to fix this issue.
