This was on 5G iPod. Go into LCD Settings. Ensure "Sleep (After
Backlight Off)" has a timeout and set Backlight to Off. Wait for LCD
to shut off. Now you can't turn on the LCD! That is the problem.

The device-independent code should probably directly turn on both the
LCD and backlight, according to settings. So, if backlight is off but
the LCD has a timeout, the it should only turn on the LCD. This is not
a feature I ever plan to use though because without the backlight the
device becomes unusable in the dark.
