Blue screen isn’t good.

Hopefully something like a loose cable or it just needs to be reset?

Here’s some basic t-shooting: https://www.ifixit.com/Wiki/Nintendo_Switch_Blue_Screen_of_Death

It can't restart and I tried some methods, the blue screen is immediate, I checked the connection and it's ok when I put the chip back, the same screen with glitch happens.

I would reflow and check the soldered caps on the apu, especially the far right anchor one

The reflow to the processor was made, the hwfly chip screen is now displayed correctly, although the payload still does not boot, if the chip is disconnected you always get the blue screen.

Is it a single color blue screen as shown in the iFixit link above?
How did you reflow the CPU? (Temperature/Duration)
What payload do you have in place?

 

[tormenta1026]

It is a single background blue screen.

A reflow was made for 3 minutes at 250 °C.

This is the payload.bin I'm using Hekate - CTCaer mod & Nyx 6.0 from dekazeta.

you tried directly from hekates git themselves and not some edited pack

also it sounds more like an SD card reading issue than anything are you sure the switch is reading sd cards when booting stock

 

[tormenta1026]

I'll try that link and when the console started if it detected the sd memory now I can't enter stock because I get a blue screen.

As additional information, when the hwfly chip did the training for the first time, I turned off the console because the heatsink was not installed for fear of burning the processor. When I turned it on again, the training took less than 2 minutes, I don't know if that has something to do with the issue.

You can reset the training and retrain from scratch and eliminate that as a concern.

It's a good idea, I'll find out how to do it.

Were you able to resolve it? I have a similar issue with Picofly. When I turn it on, the chip screen indicates that the SD card is not inserted, and if I press Vol+ and Vol- to enter the original firmware, a blue screen appears. When I insert the SD card, the screen remains black. I have already tried removing the entire chip, but it only powers on with a blue screen.

I have the same issue on a lite. Any updates?

I have exactly the same problem on a Switch lite after soldering I tested it and it showed the no sd. After putting back it showed black screen with sd card inserted and now after desoldering the chip it only shows a blue screen….

 

[barbatos41]

Same problem. Was using a v4 hwfly chip on the lite.

Has anyone solved this? Reading up on similar problems on Reddit/TronicsFix/GBAtemp, there seems to be no solution. Seems like we're screwed.

Nah i just bought a new one with broken display and replaced the Board....
