Burnt smell Macbook Pro 13' mid 2010

[MrBalls]

Hello everyone.

I started this thread in order to get some council on my macbook pro 13'.

The problem started a few days ago when i booted the mac it started to get a burnt smell. I immediately stopped the machine from booting and went looking for the problem.

Mac Specs:
Macbook pro 13' mid 2010
Intel Dual core 2.66GHz
Model: MC375xx/A
Motherboard: A1278

I can assure you no liquids or dropped in the machine or anything harmful. The burning smell came from a electronic component shown in the following images.

My ideia was at first identify which component it was, and replace it, although im not sure if the component burning was the cause or consequence of something else.







Has you can see in the picture the component is too much burned to get an actual reading on the id. And i couldn't find any schematics online for the given motherboard which led me here to this forum.

So with this thread i was looking for some council on identifying this burnt component or based on experience if this is a consequence of another damaged component and which approach should i take on the matter.

Thanks in advance for any support

Thank you for the fast reply.
When you say diode, you are referring to mousepads comment "C6603 = 100UF 20% 6.3V Tant Case-AL1 (Speaker Amp Logic)"

Yes, cap, not diode, it was 10pm when i posted that... It was a the image in post 588 that got me to that thread.
The position on the board makes more sense for a cap too.
