Sansa Clip / identifying burnt components

[mirkt]

Hello,

I have Sansa Clip (M300 v1.5) with some burnt components:

(this photo is from internet..)

Maybe someone could help identifying them?

I believe they could be the same on other versions:


I have tried to take some macro photos of my board.. Looks like it's written 236 on number 1.:

DC-DC step down?

Number 2-3? Diode and capacitor? Any more details?


Thank you in advance..

1. on my M300 V1.5 it marked as .23N, it can be LDO regulator or voltage detector, but I'm not sure. If you find more info about it - post links here.
2. diode sd106ws (http://forums.rockbox.org/index.php/topic,51243.msg236679.html#msg236679).
3. capacitor - 100p, but I measure it without desoldering, so probably I wrong.

I received a larger image from Jim:


It's 239 there..

So we got 236, 23N, 239.. 23 - sot23?

No, it smaller than sot23. I think it can be NUF2230XV6 - SOT−563, 6 lead and marked as 23x, where 'x' is month code.

Mihail, thank you for your thoughts! Unfortunately, it looks like it's not NUF2230XV6. Multimeter shows that 2-3 pins are connected to GND..

What could this symbol mean?
