Changed MAX77620 and now I do not have .1.8v and 3.3v rail

Great!

If those images are of another “preballed” IC… then that’s shocking… looks like they just ran over it with an iron, badly. I mean if the listing doesn’t explicitly state that the IC is preballed then that might be there out, pretty sure this chip is only availiable from donors so perhaps they’re selling with the expectation that your supposed to reball them

Just bringing your other topic back over here so it’s easier to follow instead of replying in three different threads :slight_smile:

I don’t recall seeing that error in Hekate before, but accoriding to the developer over on Github, it’s as a result of corruption on the SD card, I would format the card, redownload the Hekate files and re-place on the SD card. I’d also take the oppurtunity to inspect the SD card pins on both the board connector and the SD flex connector and ensure none of the pins are bent or that any of the joints are loose.

From your images in Hekate, notice how it’s reporting the temparature as 00.0 C, this would be pointing to an issue with your TMP IC (next to the backlight connector) either as a result of the chip being bad, or because it’s not getting it’s required voltages or signal, it’s also entirely possible a more serious issue is causing this
