Switch Screen Artifact and then black screen

I see, the backlight driver will not boost the output voltage until the LCD connected, I presume your stilll getting backlight when connected?

In future, I’d start with reflowing/reballing ram first, given how sensitive the Switch SoC is to heat.

The LCD is connected while testing biskeydump and I am getting the backlight. ( I could dump it with biskeydump within tegrarcmgui tool (2nd page)). Another interesting note is that when I try to mount Memloader of Emmc rawnand, Tegrarcmgui just freezes.

I was a bit too excited with the stencil, preheated and toke out the SOC

@Severence

Check your getting your +/- 5V outputs at the points detailed. Also check that your getting your enables which is a 1.8V high at the two highlighted spots.

I am getting +/-5V on the Vout-1 and Vout-2 as well as the 1.8V for enabling ( when injected hekate/ no image / only backlight)

@Severence

Also might be worth measuring your primary rails resistance relative to ground on the surrounding main PMIC output inductors juss to ensure everything checks out here, might be one is short, which I would have advised checking with the So out of circuit if thats the case.

I believe my 1V35 (Blue) is a bit on the low side. Is this the rail connecting all the components? I have recently got a thermal camera for imaging and found that the 1836 IC and main PMIC heat up while hekate is injected. I thought the 1836 IC does not generate any heat.
