I think there's an initialization missing somewhere. If the LCM is
dark after reset, I just do (in u-boot):

neo backlight off
neo backlight on

After which it stays on. So, looks like a software-only problem :)

Hmm, not sure. My GTA02v3 is actually behaving quite predictably.
The big problem with GTA02v4 is that the whole run seems to have
gotten very poor SMT, causing all sorts of stray failures.
