oled does not turn on help

[Elementron]

After installing rp2040 it does not turn on, does not charge, I removed the chip, it is still the same

forget to plug the battery in?

 

[Elementron]

It is connected, there is no sign of life, the screen does not turn on, the battery charge signal is on the screen Only turn on the fan at full speed when connecting the USB C

Agreed.


Arguably to op, if the charge indicator is coming on, then technically the screen is coming on, sounds like you're just not booting.

I didn't mean that the indicator doesn't turn on, it doesn't turn on anything at all, just the fan only when I connect the USB maximum speed thanks for answering

The rp2040 doesn't turn on on the OLED either, I removed it thinking it was bad but the rp2040 turns on on the PC I think the OLED doesn't have power due to something burned but I don't know where to start to prove that it's bad thanks

Like @Hayato213 mentioned, pictures of your solder points would be good to start with.

Does anyone have any diagram of the oled motherboard of all its components and their functions?

This site also has a whole bunch of documents in the Nintendo Switch section :

Maybe check your LCD ribbon cables.
Those have to be seated perfectly else you also won't get anything on the screen.

Did you put some (kapton) under the rp2040?
Some clones are not properly isolated on the back.

Try analyzing the voltage rails with the documentation above to see if all the expected voltages are there.
Maybe you shorted something out, which is still very fixable.
But in doubt, take you loss and bring it to a good/nice repairshop.
This can likely be fixed.
