I have a D830 which shows a blank screen. Hooked it up to an external monitor. Video tests run fine. Ran diagnostics--appeard to be a bad screen. Ordered a new LCD screen from Dell and installed it. Once in a while I can get it to boot to the LCD screen after exiting BIOS or re-flashing. But as soon as I reboot it goes back to a blank screen. Have all the latest drivers/BIOS, updates,etc.. Tried rolling back drivers also. Ensured all connections are seated properly. Cannot figure out where to go from here. Appreciate any advice?
