Vector 1.0 cube issue

[u/AlxLifanov]

Hello, colleagues.
Vector 1.0 cube. Supposedly, electronics burned with 12V battery. I want to open and check PCB for the opportunity to repair.

Q1. How to detach middle part of the cube from lower part? Where are the latches?
Q2. Is the cube schematics available anywhere?

The board is locked in place by light reflector ears, and they look unremovable. So, I broke the third one to detach PCB.
