Suss out the schematic. You probably only need to find a chip number,
then search for a datasheet.

Tried that - no joy. The PCB is marked JuYing.Ele.cn. ;-) The IC PHL 044.
Can't find anything on that unlike the voltage regs.

This should give you (if it's easy) the
identity of the brightness control pin, then you probably need to up a
resistor value supplying it.

I'd run it from a current limited supply, connect a probe to ground
via a 10k resistor, and prod around the circuit. Somewhere it will
alter the brightness, failry likely.
