I got attached screen when I started my switch oled after installing modded motherboard from aliexpress and idea what might be the problem. Note that I got green light on modchip
Ok now I have black screen with sound when I touch the screen or use joycons somehow. Doesn't make sense and yes it displays fine when docked. I reseated the lcd ribbon cable multiple times with no luck. Please helpTry doken the console tv hearing sound lcd touch.
check the lcd connector on board it self, i think some bins ripped ofOk now I have black screen with sound when I touch the screen or use joycons somehow. Doesn't make sense and yes it displays fine when docked. I reseated the lcd ribbon cable multiple times with no luck. Please help
Use microscope and see inside lce conector yes you damge pins coz you not insert the ribon like you frist hold from left and right and slide it to the back side in dowen littel bit it will be outside place easy. Back to place agine same use plastic lcd tools no damge no scratch. No damge ever... Ribon is make this pins jump from place easy.((oled console only))Ok now I have black screen with sound when I touch the screen or use joycons somehow.

I replaced the MAX7780 1EWP voltage regulator with a new one and the console is back to life. No more errors or weird behavior during glitching or after. Will test it for the next few days to see how it behaves, Thanks @superxoi @abal1000x and @jkyohoThe console is at black screen, even with chip removed.
I followed your suggestion and got an "overview" with the thermal camera, you were right! It looks like it's +7780 1EWP IC, which seems to be a buck converter for the +3.3V rail I imagine. Thank you for your help!
I attached few photos, it started to overheat as hell with only battery connected.
Does anyone know where I can source this IC's easily (withou Ali waiting time)?
Was it working before or did this happened after chip install?Hello,
I have an OLED refusing to turn on.
I can see no damages on the board, no shortcuts around power management ICs and the driver of the screen.
....
No reactions of the picofly.
My emmc could be faulty ?

I still cannot explain why this IC got shorted, but probably it was a local short, maybe due to some solder drop from the iron. Even if I clean everything thoroughly, I still imagine this is more probable cause than the eventual heating due to eMMC reball, since the heat is concentrated on the opposite side and different region of the PCB.
Thanks for your insights @Viktorsilva, though I must say that I'm not comfortable on drilling multi-layer PCB and I feel to disagree on your view of "The Kamikaze method is 100% safe". But I'm glad you got it working

What are your diode readings for +3.3V and DATA points of the Pico?
Which RP2040 board are you using?Hello, just before that, the console was booting but the screen was not working cos the dat0 adapter shorted the 2 tests points above the emmc, so I was thinking that the oled driver ic was faulty so I removed it to try without. And since this moment the console refuse to boot.
Im going to reball the emmc and remove the adapter.

Nop, I reballed the emmc and did a permanent dat0 and I still have the same issue. Maybe I burned the oled driver ic, but its weird on my screen connector all the values are good.
I have to wait to receive the IC :/
Just don't buy clones and purchase RP2040 directly from WaveshareHello everybody
I have an rp2040 clone ordered from Ali. I installed it on my switch v2 and I get an RST error at boot. The rst point of the chip is shorted. When I remove the battery, the short circuit is no longer. When I put the battery back in and restart it comes back with the error **.
By changing the chip, the console boots well on hekate.
... Should I return it or Try to fix the screen? I'm confused
If you know your cfw and ofw firmware you can chose the hats pack for your console....hello! Can anyone tell me why this happens when I try to log into the original system?

You don't need anything from the 'dead' Switch but you need a backup from a working Switch :Hi guys.
I got NSW V1 from dead, but It got EMMC changed.
Have any way to recreate NAND from zero without the original nand?
