I am working on a HP dv6000 with no display. It will power up, indicator lights are working, but no display. I tried the "flashlight trick" and tried to view desktop items under intense light, but nothing was visible. I believe the display inverter is bad, but I would appreciate information on any available testing procedure for this one before I order a new one. Any help?

Thanks in Advance

if inverter is bad, you can still see the image on the screen. if you don't see, so there's lack of LVDS signal from MB to LCD screen. in this case, you should check connection between MB and LCD, and if your laptop has nvidia geforce7200/7300/7400 videochips or nforce 6150go video, you should repair this laptop via warranty service.
