Please help! I’ve got an hp pavillion ze4125 that isn’t illuminating on the display screen. If i shine a light on the screen you can faintly see what is being displayed. If I plug an outside monitor into laptop everything is ok and functional. I can’t afford to take it in for repair and would like to know if problem is a replaceable component and or what it would be called or better yet a part #. If anyone could be of help, it would be greatly appreciated!! Thank-you in advance for any help. ;> “Nuts”
