I am working on trying to repair a C720 that is a few years old at this point.  As part of my troubleshooting I have tried the ESC+RELOAD+POWER boot, with no change to the screen. The blue power light stays on when the system is booted and not connected to power. I can connect an external display and have that show up. In just the right light I can make out what is on the C720 screen, however. It seems to me like the backlight is burnt out or something similar.

 

What are my options on repairing this issue?

    I think the display and back light are one assembly on these. My notes say the part number on the display is KL.1160D.012, but there have been a number of models so it might be different on yours. The C720P would certainly be different due to the touchscreen digitizer.
