For 820-3330 resolder U9800 first!
For 820-2914 or 820-2915 use CMIzapper Tiresias.

on the board 820-3330 there is no u9800, there is u8900 it is the pwm of the gpu, if you mean it, is it just remove it and ready?

Thank you

I am messing up the 820-3330 and the 820-3332...
Resolder U8900, or check the GPU VCORE voltage with an oscilloscope.
If the GPU really is bad then our CMIzapper Tiresias should work on that model too.

You can use the CMIzapper Tiresias if you want to preserve the backlight control in High Sierra:

To see how to mount:

Advantages are:
Easy to mount. No irreversible changes to the GMUX. No software to install. User can zap the PRAM safely. Backlight keys F1 and F2 work even in High Sierra / Mojave.
