Hey folks, here's a good one.

I've gotten a Pavilion DV8000 in for repair. 17" LCD showed lighter and darker vertical banding, which I diagnosed as a bad LCD cable. Replacing the cable removed the banding -- but also removed the image on the screen altogether. Perfect backlight, no image -- just white.

Replacing the LCD also proved no love whatsoever -- same issues.

Returning to the previous LCD cable with the new display resulted in the same results -- white LCD (backlight, no image).

External (VGA) connector to a second monitor works fine -- perfect image. Instructions to turn the internal LCD on or off (using fn+f8, I think it is) will turn the backlight on or off on the internal LCD.

So, I guess my question is this: did I get hosed on the purchase of a shoddy internal cable? Did I damage the connector on the mobo (I can't see that I did -- all pins seem straight, and the connector goes in with nearly no resistance)?

My next step is to go back to square one -- use the original LCD and original cable, but at this point, I'm $140 in the hole, and no resolution to show for it.

Any thoughts would be appreciated.

Thanks!

Try using the old LCD and cable. Problems appear if laptop is booted into Windows or are they present even if you boot into BIOS settings only? If the problem/s are NOT present if you boot into BIOS settings only then it could be drivers related.
