HP dv6000 black screen

Apr 27th, 2009

I have a hp dv6000 laptop. I can barley see everything. Thought it might be a backlight. Was on the phone for 4 hours plus with HP and tried everything. They quoted me 422.oo to replace the backlight. So I bought a new screen. I installed it and it does the exact same thing. If I hook up a monitor it works just fine from the rgb. Any idea's?

The backlight is definitley not working here. For it to work, the light must get high voltage from the inverter, and the inverter must get power and logic signals from the motherboard through the inverter cable. So, the light is not being powered. Why? Check the cable and the inverter connections first, then replace them one at a time. Most likely the inverter is a fault here, so buy one of those. It is the thin little circuit board that the backlight is plugged in to. If that doesn't work, then try the cable. Try and repost, good luck.

Thanks for the help. That is what I was thinking. I ordered another inverter on sunday and it should be in anytime. I will let you know how it goes. Again, thanks.
