Replace the standard 8570w fhd screen with a 8560w Dreamcolor screen?

Hi guys,

So is it possible to replace my regular fhd 8570w screen with a dreamcolor fhd from the previous 8560w?

Thanks.

 

They are the same, so it is possible, BUT you need the whole assembly. Do note that I haven't looked whether or not the connectors are the same (they should be). On the 17" (8740w, 8760w and 8770w) they are.

 

Thanks, but can you explain what the whole assembly is?

 

Hi everyone,

I would also love to know all the details on how to complete this exact conversion correctly and all parts that'd be needed.

 

It would be awesome if someone that have done the exact same before could help us out..

 

I doubt that anyone has done it before, but even if someone did, I haven't came across it. By the whole assembly I mean the entire top (display) part, since it is not only the display, but two cables, a special board (Color Board) and on some models there's special indentation for the CB, which is not there on the stock panels (you'll have to grind your cover if you have found the display + cables + CB (they do pop-up from time to time)). The reason I say that you need the whole assembly is 1/ Because you need everything that's inside (obviously) and 2/ They are (near) impossible to be found separately.

 

Ok thanks, I at this moment got my hands on and a complete 8560w with Dreamcolor.. the most easy way is to replace the entire cover (screen+outside cover) with each other and just change the black plastic screen where it says modelname ''EliteBook 8560w'' & ''EliteBook 8570w'' vice versa.

So I opened them and the dreamcolor cables on the motherboard were easy to disconnect BUT there are another small black cables going trough round the screen and are connected to the motherboard on the downside of the DVD-drive, I don't see any possiblity to disconnect them (I believe they are of the microphone/webcam.) Anyone know how to disconnect them? Here's a pic of what I mean:

(ps. I took out the screen at the picture but it wasn't necessary for the plan):

 

Aren't those the antenna cables for the WIFI and WWAN modules? On my 8570w they look and are arranged exactly like that and are supposed to be in the edges of the screen's housing.

 

Thank you! You are right they look like coming from from the wifi antenna and WWAN (wich the 8560w have). My bad I thougt they were of the webcam.. any idea how to disconnect them? Also move the WWAN module (that the 8560w have) on to the 8570w..?

 

These are the WiFi cables. Open the back side, detach them and pull them out. Already answered, sorry haven't refreshed the page.

Just pull the back end and they would pop-off. Why do you want the 8760w module? Just unscrew it and pull it up to 45º angle and away.

 

Unfortunately I don't know how to remove them from the body of the laptop, since I haven't taken apart mine, I just know how to disconnect them from the modules, located under the cover. Noticed they look familiar, glad that I could help
If you need some help on how to take apart stuff you can check out the service manual, available to download here:

Please keep us updated on how the transplant is coming along! I am very interested and probably will do this to my 8570w

 

Ok, I managed to get the job done..

Here's some of my experience:

Method 1: replacing just the (inside) screens and the cables vice versa. (Wrong method!?).

1. When doing this first thing I noticed is that the cover of the 8560w (DreamColor) is 1mm thicker than that of the 8570w (non-DreamColor). At first I was not sure if that's because of: old model vs new model or DreamColor vs non-DreamColor. So I tried to put the DreamColor screen inside that of the new 8570 cover BUT when tighten up the screws I felt like I was squeezing it on to place and saw a little bend on the screen when I turned it on I saw bleeding white lights from the corners. I noticed when you screw it all the way it will cause the bleeding, it just wasn't a perfect fit! (This might also explain why some people complain about bleeding of their DreamColor screen in the lower left/right corner, perhaps their not using the original thicker cover?!) I also measured the (inner) DreamColor screen and it's also slightly thicker than that of the regular one! And the DreamColor cover have 2 screws that hold the ColorBoard in place, the other don't (I had to ducktape it). For professional result make sure you have the whole DreamColor cover!


Method 2: moving the whole cover vice versa or getting hold of the original DreamColor cover (Correct Method).

2. To do this you first have to take out the 2 video cables one big and one small of the motherboard (they are the same on the DreamColor and non DreamColor), these 2:




Then you need to also take out the wifi antenna cables. To do this first loosen the cables from the antenna at the bodem than CAREFULLY pluck 1 by 1 out. Then slide them CAREFULLY one by one trough to holes as in the picture:



Loosen the hinge (on both side):




and take them of:



Now you have the whole screen cover + the antenna cables wich you will install on the other one.

 

Thank you very much for sharing your experience! Procedure is clearer to me now, it seems method 2 would be much better to execute, since indeed in the service manual DC2 display housing and misc parts differ from the regular FHD screen ones, even the hinges. However, I would be very grateful if you could clear up the following questions:

1. You did mention this briefly, but are all connectors from the DC2 screen to the laptop itself identical to the regular FHD screen ones?
2. Is the colorboard board the only additional part required to drive the screen correctly or are there any other parts required?
3. Where is the colorboard supposed to be housed originally, in the screen assembly or somewhere in the laptop's chassis?

Thanks!

 

You're welcome!

1. Yes on the motherboard itself they are the same 2 as in the picture above they only differ on how to connect to the screen!
2. The ColorBoard is integrated with the one and only video cable! It is basically just one big cable with 2 seperate connector at the end for the DreamColor panel (wich takes 2) whereas the normal cable/screen only takes 1.
3. The ColorBoard is screwed on the cover behind the screen. Here's a picture (note that I have removed the tape on the second picture where you can see better).

Left ColorBoard (with the tape on) and screen connectors go to the right:


Without the tape:

 

Glad that you sorted everything, that's why I said from the ground-up that it would be best to have the whole assembly.

To clarify a few things:

- The motherboard connector is the same (unlike Precisions), BUT the stock panels connect to the LVDS lanes, wheres the DreamColor connects to the DP lanes (check them side by side and see that they connect to different pins).
- As I said before - the ColorBoard is NOT the only unique part, it is the whole assembly - both cables are different, as well as the housing and of course the CB, but that's something that pretty much everyone knows already.

Anyway, enjoy your new DreamColor machine

 

Thank you triturbo for your input, special thanks to Sanderqw for sharing the progress in photos and detailing the steps

So locating a complete DreamColor display in its housing, simply removed from the hinges, would be required to complete the conversion correctly.

In case I am able to find such a complete assembly from a 8560w/8570w and IF it is lacking the webcam/mic option, can I transplant my webcam and microphone array along with my existing internal bezel that houses them and the 8570w silk print to the new housing ?
I did notice this question was partially answered in the 1st page, but I am particularly interested in this scenario.

Thanks!

 

Yes, no problems there since they use separate connector.

 

Yes the motherboard connectors are 100% identical. The Stock panel connect directly with 1 connector to the screen. The DreamColor connect first to the ColorBoard and then to the screen with 2 connectors.

Thank you, sure will enjoy it!

The webcam cable is stuck on the video cable so you have to use DreamColor cable for the webcam also but you can disconnect the webcam at the very top on the webcam itself.. But best thing is not to mess with it just get a hold of the whole cover with webcam.

 

Ok so yesterday I didn''t had much time to test it really good, today I've noticed some issues with the DreamColor panel (the regular panel wich I put on the 8560w is just fine..)

Issues I'm getting: the computer starts up with the screen completely turned off (I can here the fan and Windows sound so it's booting just don't showing anything). After turning the laptop off/on, off/on a couple times the screen will go eventually on..what's up with that? Also when watching a video the blacks are kinda compressed and of lower quality than it was before on the 8560w and I see a latency line in the middle of the screen (top quicker/low slower) when watching videos that have fast changing shots..? I have updates the BIOS to latest, updated Graphics card and problem remains... Does HP use a special kind of BIOS for DreamColor notebooks?

 

Now this sounds concerning. Please, if someone might know what the cause of such issues might be to give some input.

Thanks

 

I guess a lot of things are different between 17" and 15" models. Sorry for the mistake.

 

Yes it is very annoying.. I'm thinking of maybe some loose connection but I remember I was sure connecting it good and it's strange that it sometimes turns on and sometimes stays off..
Anyway tomorrow I'm gonna open it up again and re-connect the cables just for sure, let's see if that solves the problem..

No problem.

 

In the mean time it would be helpfull if someone could tell for sure wich one of these connectors is for power the screen and wich one for the colors (Im guessing left power and right color)?

 

The large one is for display related stuff - power, backlight control, LVDS and DP, the other one is the camera connector. So they are separate after all, they are just tied together.

 

Ok I have opened it up again and re-connected all cables this time I made 100% sure it was connected right and the screen problem not turning on seems to be GONE !
Also the problem with the blacks is GONE! That was a driver issue I installed the nvidia drivers directly from the nvidia site. You must first install the official drivers of your model (8570w) from the HP website!

Now the only issue remains are these ''latency lines''.
To give you guys a better idea of what I mean here's 2 videos (take a close look at the fast movements): &

If you can't see it clearly on the video here's some stills:

 

If anyone else have the same DreamColor display (of 8560w/8570w) and can check if those lines are normal (I doubt it) it is very appreciated.

 

DreamColors have the option to select the refresh rate. Depending on the video (24FPS or 25FPS), try 48Hz or 50Hz. You should notice the difference.

 

Does this mean that when using a DreamColor for regular video watching and running the laptop at the standard 60 Hz, all videos recorded at lower than 60 fps would exhibit this behavior ?

 

Any LCD display has such behavior, it's more obvious in DreamColor panels, since they are a bit slower than most TNs out there and about on par with mass-market IPSes (speed wise, colors are another story, obviously). It's all about response times and refresh rate. As I said, you can compensate when you lower the refresh rate.

 

So in short, this behavior is completely normal and not a problem, resulting from the conversion?

 

I have tried all refresh rates 48,50, 60hz and even tried lower resolution and even went from 10bit to 8bit and still not gone.. I can say for sure this issue was not before on the 8560w!

Also the problem of the screen not turning on is NOT GONE as said previous!
It's something weird: If I turn off the laptop for let's say more than half hour I have to turn the laptop on for about 5 times for the screen eventually to go on completely!

First, second and third bootup time it will go on black screen (with backlights on for a couple of seconds) and then completely turns off (no backlight nothing). At the fourth time it will turn on and see Windows logo for a second but then it turns off completely again and fifth time it will finally completely turns on! (All these times Windows is booted just the screen is off!)

Very weird because when it's on and I turn it off and immediatly back on it will go on right away! After aprox. an half hour being shut down it will go back to the previous 5 times needed to boot up.. It's like some internal BIOS/motherboard battery was ''remembering the screen'' before it's drained or something..

 

I have never seen this behavior on my 8570w too, if you do find out what is causing these problems, please share your findings.
It is starting to sound to me like a bad idea to convert my laptop And that is something I really want to do to it.

 

Among my times replacing screens and video cards in my 8740w's, I occasionally had similar problems that I solved with multiple re-installations of the graphics driver and with making sure to install the HP Mobile Display Assistant (which itself solved the problem of the screen being stuck on a single degree of brightness (dimness, actually!)---I even had to do the Display Assistant's installation twice in one case.

 

Edit: The post was meant for another thread.

 

Ok after some testing I changed OS (from Windows 7 to Windows 10) and the latency/refresh lines are completely gone.. so it is a driver issue! I myself dislike Windows 10 and I went back to Windows 7 so this problem is not solved for me but good news if you're on Windows 10!

The screen not turning on immediately is still there though.. but im starting to think maybe it's a motherboard/power connector issue wich got damaged when I opened up the laptop but im not sure..

 

If someone could help me out with the 8570w driver CD (wich came with the laptop but I lost mine) to upload it on google drive or something.. I want to check if I install all the original drivers if it solves the problem.. I would be very thankfull!

 

Sanderqw thanks for your input, I personally like windows 10 and had all my win 7 based systems upgraded to it. Can you please clarify if the turning off issue happens while using the laptop? Does it occur when adjusting the angle of the screen?
I don't have the original CD as well, so I can't help you, unfortunately.

 

No when the screen is on it works fine under all circumstances! It's just the power on..

 

If the problem occurs only after powering the laptop on (where Windows splash screen shows, etc ) and is a few seconds, I have no issue with that.

You can find all your drivers, here:
http://h20565.www2.hp.com/hpsc/swd/public/readIndex?sp4ts.oid=5257503&swLangOid=8&swEnvOid=4059

You will have to manually d/l them though

 

Thanks, but I've allready tried those drivers with no succes.. I really need the original ones on the CD because those automatically installs everything you need for the specific hardware (different 8570w specs) and also the first original versions..
