Default hp dv 6700 on laptop lcd

I have an hp dv 6700 that gets no display. The monitor lights up but no picture. I have replaced the lcd, display inverter and the monitor cable to no avail. If i hook up to an external i get picture. I also flashed the bios. function f4 does noting. The only component left is the systemboard but i don't know if that is the solution. I am stumped! Any help would be greatly appreciated.
thank you
Howard

Did you replace the LCD? As in, bought a new one? Sounds like a bad backlight.

Just hook it up to a external monitor, if you get no video at all. It's the system mobo, I put my bet on the moterboard. HP's are notorious for this in my experience.

As the external video work, I think it's something with the lcd connector pcb.
