microsoft surface pro 4 repair

[spiglys]

Hi guys here, I have a question can somebody identify what is the element here at microsoft surface pro 4 board and where I can get it except donor board . thanks for smart people.

 

[Harald Kapp]

Might be an oscillator/crystal. Not sure.
What makes you think this component is defect?

Agree with Harald, most likely an oscillator module I see a couple of capacitors hanging off pins

I'm not sure if is defective but if i look at it it looks like burn so this only my guess

 

[Harald Kapp]

Improbable. This kind of oscillator usually doesn't overheat.

 

[spiglys]

so why it looks like burn ? is this normal ? any way to test ?

Harald erred on that one, they are powered, so hence they can fail and cook
that looks pretty obvious from your pic

I think you are right. i found something interesting and I think this bad guy is the problem

Looks ok to me...

Looks cracked. Doesn't necessarily mean its bad, could just be the package but its definitely suspect.
I looked a little but did not run across any sot23-6's with code of AJ8. If you find out what it is make sure to let us know !

look closer ! it's cooked

First picture looks perfectly fine. Second picture looks off but if its same board as the first picture then seems to just be lighting imo.

yes, and probably not his board

lighting, definitely not, there is obvious heat damage

 

[narkeleptk]

*shrug* I think its the same board with different lighting and angle.
Only TS could really tell us I guess.

I don't know what it is, but it looks more like AJX to me.

I don't know what it is, but it looks more like AJX to me.View attachment 49457

I checked X first (both with no good results) The smaller image I looked at seemed like it had some faint curves so I was leaning to 8 but this larger blown up one you are providing looks more like an X to me as well now.

Hello,

The part coded with AJX is a TLV3011.
(found on this page : http://chip.tomsk.ru/chip/ChipDoc.nsf/vc1!readform&view=smd&cat=A&start=15001&count=500 )

[spiglys]

yes this is same board . @bertus you are correct this AJX thanks for smart answer, but it seams it has 4 variations under AJX chip

yes this is same board different angle

Hello,

@bertus you are correct this AJX thanks for smart answer, but it seams it has 4 variations under AJX chip

There is only one in the housing you have.
The others have other housing or a small x.

@bertus ok it means TLV3011AIDCK is the correct part. and I will attached other picture do you know what is this component because I can't find by the number of part?
