820-00165 does not show image.

I've already released 3 macbook air without solution, because it doesn't give video, I clean the ME region, I see all the components around the u6100, PLT_rst high, ALL SYS high, Vcore high, all that's left is the fucking mac to turn on, but it has video, I'm outraged. Please tell me which component is causing this, for the love of God ? is the PCH, SMC, CPU, controllers ?

Do you get USB activity at least???

No USB activity

Then why this fix about image???

In case like this, clean ME region of original BIOS doesn't help.
You must try FULL known good BIOS.
