Using a APIX1 screen with NBT EVO HU

I purchased an NBT EVO got it coded to the car. And then sliced the LVDS cable and put a buck converter in between the power and ground wires.

Checking my original HU (Entrynav1) voltage was hovering around 8.05-8.2V so I dropped the voltage to 8.13 I now get a something on the 6.5 inch screen but it says "No Signal"

Guessing I need to code again can anyone give me a hand?

Voltage to 8.42V
Apixmode = APIX1
Color Depth = 18
Com Mode = spi
i-Level = 18-03

also check CID_DISPLAY_REZ and CID_DISPLAY_SIZE for correct display settings. If evo came pre-coded, seller might have set evo to large screen size.
CID will work with higher ilevel but will randomly stay black or say "no signal" after locking the car. If you reboot headunit by pressing powerbutton for 45s and screen still doesn´t work, coding or voltage is not correct.

if everything is correct, it might also be an issue with the Voltage regulator. get an multimeter and measure the output voltage of the voltage regulator. these one with an voltage display often show incorrect values.
