I've just replaced an SP3 screen. I've done a number before without issues.

Prior to replacement the screen was cracked and the display froze on the surface boot logo. Sort of as if the bios were engaging but couldn't find the drive to load up the OS.

prior to removing the screen I waited until the battery was dead and then went ahead. the screen came off relatively easily, no trauma to any cables apart from the digitiser, which was dead anyway. in cleaning the edges of adhesive I tore the copper strip on top of the USB port - but that's replaced now and certainly no damage to the physical port underneath.

I now get no response from the hardware at all. no screen light, but also nothing hardwareish like the fan going or the processor warming etc.

I've tried hard resets and i've tried booting to UEFI and to a usb image. all without any noticeable change. this is not a DOA screen as the old screen is exhibiting the same behaviour.

the charge port works fine. I've measured the voltage of the battery before (7.4v) and after (8.7v) charging and the top right of the tablet gets warm after a chunk of time on charge. the keyboard lights up as well; and is responsive to the caps and Fn keys (the light turns on and off).

any clues about where to search for issues? Anyone know where I can find the circuit schematics to trace the power lines?

So my out of warranty Surface Pro has developed a potentially very expensive / annoying problem......

One of the CPU fans has become extremely noisey when the CPU is under load and it's trying to cool the thing down. We're not talking about wooshing air here, it sounds like a mosquito has got inside and is buzzing like its on drugs. Essentially its sounds mechanical...

I'm loathed to take the machine to Microsoft as I think I'll get automatically told to send it off for servicing and it'll cost me $300 - $500 to replace a $20 fan. So what I'm trying to find first is a safe lubricant that I can spray into the vents on the device (ideally while it's on) in an attempt to lube up whatever is causing the buzzing.

Does anyone really technical have an suggestions? My reading so far suggests a silicon based spray is good. But I'm terrified to spray anything into it!

If the spray solution doesn't work I'm guessing the only option after that is to surrender my credit card to Microsoft?

Am I missing a crucial step in reinstallation? Is this a common occurrence? What do I do?

I live in Hertfordshire so anywhere around there would be great

I have an Problem with my Surface. It's not turning on anymore after someone changed the screen on it. I quickly dissasembled it and spotted these 3 diodes that looked burned (I circled them in for you too):

Now my questions is can anyone tell me which diodes these are? I want to try to replace these 3 to see if it works again. It's currently not even turning on even with the charger plugged in. The Charger lights up tho. Do you guys think this might be the solution that fixes it? Or might be there something that is also broken that doesnt let the surface start?

Thanks in advance

My screen is cracked and I can't find any reliable supplier. I can't find a replacement guide for the device as well.

How to correct it ?

Image and text on the screen use to tremble, up and down, from time to time. When this happens image and text become blurry.

When video is playing,sometimes, one frame freezes, while in the background the video is still playing.

Is it a software related problem or a hardware malfunction ?

(once I hooked the Surface to a monitor, the video played fine,while the problem persisted on the Surface screen)

These are the pictures from the service guide showing the adhesive and speaker mesh.

Hello there,

I've bought this surface on 2015 December and latelly I've checked the screen during boot, while having a dark background a light shadow appears in bottom of the screen. Is it normal with this kind of screen? Is it any source of light?

I drop a image so you can look!

Thank you

Any other suggestions or can we conclude it is just a faulty battery? Thanks in advance.

I am in the process of doing my first screen replacement on a Surface Pro 4

I've got the screen off and disconnected all the cables without an issue following the guide here but I accidentally snapped one of the WiFi antennas during the screen removal.

The only website I can find for the part is :-

http://www.powerbookmedic.com/Microsoft-...

However they are out of stock

Anybody know another place I can get one? Tried searching for the part number (X939878) online but that's the only useful website that comes up.

Help!
