Help Identifying Component on Nintendo Switch OLED

[Apophis1986]

Hi, does anyone know what this component is?

My Nintendo Switch OLED won't start, and when I checked with a thermal camera, I noticed that this component is flashing intermittently.

When I checked with a multimeter, both ends have continuity.

Thanks!

I'm not sure, but I guess it's an SMD 0805 1µH inductor.

Can someone confirm this, please?

You should check for other solder work instead of this inductor. It rarely got broken

I think you're correct because it's also mentioned here :

As @jkyoho mentioned already, it might be be an effect of something else being broken.
That chip above it is some power regulator for the audio IC so that might be causing the problem.

Thank you for the advice.

I’ll check it out.

I’m not sure if it’s related, but I think it stopped working right when I placed the Nintendo in the dock. I replaced the resistors at the CMD point because they were burned out.

Thank you for the response! I'm learning to diagnose Nintendos, and any advice helps me a lot. I'll check out what you suggested. Best regards.

Hi,

Upon closely inspecting the indicated area, I found a small bridge from the inductor I mentioned to a 4.4 µF capacitor next to it. I removed the inductor, and it seems to have burned out because of the bridge, as there's continuity across both ends. I'm going to order some replacements to see if changing it resolves the issue. As an additional note, the 3.3V isn't reaching the Picofly, as there are no lights. Does anyone know the size of the 4.4 µF capacitor? Thank you very much.

Hello again!

Okay, in the post you mentioned, they are using the same scheme as I am... I see that the values in the scheme are not reliable. Could you confirm if the SMD 0805 1uH 50mA inductor I ordered will work to replace the one I marked in the image?

Why would you pick a 50mA inductor if the max77801 IC states output 2A?

Another mistake made, thanks for correcting me
