Okay, this one seems to be either hardware or BIOS related. I thought I would try to reinstall Windows 7 but after the reboot, when the install is finalizing, the display turns off and never comes back on. A test by going into the BIOS and exiting (exiting the BIOS turns off the display) and the display never comes back on again. Even a simple restart of an OS running (soft boot), the display turns off and never comes back on. It only comes on when the BIOS does a hard boot. I will be talking to Dell tech support unless anyone has any ideas...
i was considering replacing my screen which is intermittant with a new one, preferably with a higher resolution. and it would be nice to see how you went!
also i would recommend trying a linux Live CD to see if your problem is related to MS or not.
perhaps also the "ultimate boot cd for windows" by default it starts up with a low resolution so if something goes bad because of a high resolution then you would be able to incriment up to a high resolution. some pages suggest you need a new/better screen cable for a higher resolution.
it could be a possibility that you may need to uninstall the graphics drivers and reinstall. (yes i know this is an old topic, bot maybe someone else needs this)
i have done some research and some of the lower res laptops have only one data channel wired for the screen a higher res screen requires more wires. not sure if the second highest res needs this....

Did you change the inverter with the screen?

Yes, sort of. Both the original and the new display are LED backlit (not CCFL) so the inverter circuit is built on to the display itself.
