I have HP DV9417CA (DV9000 line)
okay. so this is the 2nd day this has happened.
first happened last night, where my internet was dead slow, restarted. woa la. finxed the net, works fine
restarted again later, no LCD.

I moved the lcd back and forth for a bit, started again, back on!
Today, i tried that, and that doesnt even work. The LCD is black, no back light or ghost image when lighted with a flash light.

I flashed BIOS to the newest ver, no help. (2009.3)

So i took the laptop apart, plugged in the external display (1080p TV) and went to device managers.
under Monitors
Defult Monitor
Defult Monitor
Plug and Play Monitor

I unplugged the LCD wire and rebooted, i see the same three monitors.

I dont think its the lid switch, because if thats the case, i should still be able to see the LCD registered right?

I dont think its the inverter since i have no ghost image,

Now im just really confused. help pelase!
