Hi guys, I've configured the vtx table for the TBS pro32 nano v1.1 as per their website:

# vtxtable
vtxtable powerlevels 4
vtxtable powervalues 14 20 26 30
vtxtable powerlabels 25 100 400 MAX

When I set the power to MAX through SmartAudio, the screen initially show the footage (low power on disable) but after a few seconds only horizontal white and black lines:



I’m using a Diatone MAMBA F722 MINI STACK Flight Controller with a 5v 2A (max 3A) BEC.
Connected to the BEC, there’s a Runcam split 3 micro (650mA) and the VTX (400/450mA?).
Everything works correctly at 400mW (390mA).

Any idea?
