Switch OLED teardown V1/V2

[doom95]

Would need really good pictures to judge that. But if the trace is there, don't damage it further.

you said the modchip is turning on without pressing the power button.

Check the 3.3v line, maybe you soldered at wrong point at switch board.

You should solder it at the red point marked on image (on the capacitors)

the 2 caps have 3.3v right? because mine got bridged and i think i shouldn't bother unbridging them.

Yes, are bridged on superior side (assuming you have placed the motherboard on a table, with the usb c connector pointed to you)

Yeah, i've had no problem!

Has anyone ever had an issue with an oled going into emmc slow mode after trying to restore boot0?

I've got an hwfly oled, which wouldn't boot into ofw, so I put a thicker wire from dat0 and moved it, so it would get less interference, but it was the same. So I tried to generate a boot0 with emmchaccgen, then restored that (after backing up the original boot0), but now I just get pkg2 read failed when I try to boot ofw, since I don't think it flashed properly, I got the emmc slow mode error after trying to restore both the generated boot0 and the original.

Not really sure what to do from here.

Hello!!! This thread has been very helpful while installing HWFLY v6 on my Oled, thanks to everyone!

I did lost the CMD/A Resistor and put a new one from another switch 4.7k Ohm. First time soldering on this tiny tiny scale.

I managed to turn it on and go into OFW with no problems, but when it shuts down the fan keeps revving for a very long time, is this normal? Did I short something? I guess if I keep the switch in sleep mode it wouldn’t be a problem but…

So... i realized this crystal thing broke any idea what is it for, can i replace it with another one?. I sent it to someone that do jailbreaks and stuff but in Chile is not very common... So any ideas??



I sent it to this guy because my switch has troubles turning on, first time plugin the battery it blinks purple and then green and i can go to CFW but when i turn it off the fan starts revving and if i try to turn it on it blinks red 2 times purple and then a solid white light, i guess it has to do something with the capacitors near the cpu (as the colors sheet says) and everytime i try to turn it on after that it does the same. But if i disconnect the battery and connect it again fan starts revving and i can again turn it on with the purple and then green light and go into CFW

So there are a couple of things wrong with my installation:
- Turns on first time after plugin in the battery but second cicle gives a white light error
- Fan is revving when the switch is fully off
- When trying to go into OFW sometimes it gives me this error (Attached picture)
- It thinks that a headphone is plugged in and sometimes it doesnt, it changes constantly


(OFW Error)
Thanks for reading and any help/idea is welcome!

That's the power regulator for the joycons charger and the fan

Thanks!! i did change it for one from another switch and its all working.

Still figuring out why does the switch thinks a headphone is plugged in and why does it cycle between modes sometimes, like it goes from mute to system sound to headphones, then nothing but no sound and then again does that

Hi,
I ripped off a component from a Switch Oled motherboard it is the resistor/capacitor near to CMD point (not the CMD resistor)
I suppose it is a 0201 resistor but I don't know the value.

In the photo is the component at the top of red marker.

Can you help, please ?

Thanks

I got a boatload of eMMC DAT0 adapters in and as promised a little while ago I'm offering them cheaply in hopes of helping some people out here and perhaps recuperate part of the investment. I'm not too likely to work on 1000 devices in this lifetime so might as well distribute a few

First some pictures...

Nearly 1000 adapters

Reflow attempt: I added some flux to the adapter before shoving it underneath the eMMC. After a simple short reflow profile it was firmly attached already. This should definitely form a good, lasting electrical connection, hopefully better than simply relying on friction to do a good long-term job.

Regardless, conformal coating certainly adds some mechanical robustness, so I tacked it down with a small layer.

If you need a small quantity of adapters, I've repurposed a paypal button over at https://munia.io/devices for a simple checkout. Price will be €1 per adapter, €3,10 flat-rate shipping world wide in untracked envelope, and 21% tax. Hopefully that seems reasonable.

Do you happen to have any more of these lost ones available for sale? I still lack the control and self-control to attempt a kamikaze, so I've always wanted to get these flats from you that seem to be of very high quality.

Hey there, I'm missing these two capacitors on my OLED Console. I have a few donor Boards from Lite and V2 Consoles here. Mayber someone can tell me which one I can use from the other boards. Thanks in advance.

Hey there after installing the picofly with succes I was greated with this yellowish tint on my screen and cant get it away. I already checked the ribbon cable and it looks fine. Also the resistor for point a is 4.7k ish. So im kinda confused what happened. I also did a boot with the chip uninstalled and still got the yellow screen.

Check lcd ribbon

Check lcd ribbon

The ribbon is clean and so is the connector. Its still a nice form but would be a real bummer if it bended too hard I guess

Im ready to bet that the connector has a damaged pin. Have a look with a microscope inside the connector and you might see a pin either missing or folded over.

It has happened to me and I had to remove the connector from the board and re-solder a new connector. Good luck.

Thank you very much suggesting I should take another look! There was indeed a pin bent it it shorted some other pins. I was lucky that pin was for ground and even more lucky I managed to remove ot with a sewing needle without replacing the connector. My switch oled is now perfect woth picofly. Alot of hearts to you <3
