To clarify: my screen looks exactly like the images posted by the OP, but it is not an intermittent problem happening only after wake-from-sleep. It's a permanent feature of the display. The system is dual-boot, sometimes running Windows 7 and sometimes Ubuntu, and the screen looks the same with either OS.
I am curious if these issues were ever resolved. I have an e6400 that is out of warranty and the LED backlight has completely failed. I am able to see a ghost image on the screen when illuminated by an outside light source such as a flashlight, but there is no backlight. Display is normal when connected to an external monitor, and I have attempted all software fixes such as adjusting brightness and disabling ambient light sensor. I have also updated the BIOS with no results.
I was told I would need a new display, but I would like to know if there is another potential cause such as an inverter or a fuse before I order an entire new display.
Thank you for the reply, you got at the root of my question. I am aware of a converter for the LED backlights, but I am questioning whether it is possible to replace just the converter, or if there is some other element, such as a wire harness or fuse, that could have caused my LED backlight to fail.
I would like to avoid ordering a pile of replacement parts that I don't need

Since it's brand-new, I would not bother troubleshooting - request a replacement system.

I'm curious what the resolution was on this. I have a brand-new e6500 with exactly the same problem.

This is an inverter issue and it needs to be replaced.

LED backlights don't use inverters - they use a converter board, which may or may not (usually isn't ) separately replaceable.
