[Q] Replacing AMOLED/LCD & Digitizer - Desire Q&A, Help & Troubleshooting

Hi,
My AMOLED went crazy after 6 month, purchased a new LCD (link, ebay..), trying to install it I damaged the Digitizer's flex (attached), Qs; this one says ...USA are there different types?, would the LCD come on with the Digitizer's flex damaged? mind didn't! is this normal.
Just ordered a new Digitizer, will try to install once received.
Kindly advise on how to do it and/or your thoughts if you have had similar experience.
Thanks.

Yes, nothing to worry about. I have replaced many digitizers and LCD screens. The LCD and digitzer are seperate components, they are not connected with each other. Bottomline, you don't need to worry .
But if you have a amoled phone, you can only use amoled and not SLCD. Otherwise the screen won't come on. Tried it myself and it didn't work.

Many thanks Lenny,
Unfortunately, I'm told; if the LCD is installed and the phone turned on, this will brick the phone, which I already did so I assume it is bricked!!
My Desire was imported and returning it to HTC isn't an option, any thoughts on other solutions or should I just give it to my 5 year old to play with??
I appreciate your reply.

No this is not true.
I am not really sure what you mean, but I will try to explain.
If you have a phone with an AMOLED screen, you can not use a SLCD. Tried it myself and it didn't work. The screen wil not turn on. So you must order an AMOLED.
You cannot brick your phone by placing a SLCD. Buy an AMOLED screen on ebay and your phone will come on again.
This is the serial number for AMOLED: 60H00287.
Just search for that number on ebay and you will get lots of results.
And even if you're digitzer is damaged, the phone will turn on but you won't have a working touchscreen. But your AMOLED will work.
I hope this answers all of your questions. And if not then I will try to answer them all

Lennyz,
Tank you, Thank you, Thank you...
Many thanks, this is the response I got on htcdesireforum dot com: (http://www.htcdesireforum.com/htc-d...lacing-amoledlcd-digitizer/new/?topicseen#new)
[REPLY]"Putting an SLCD screen in an AMOLED Desire will brick the phone as soon as you try to turn it on, which means you'd have to send it back to HTC for a repair which will cost you nearly as much as a new phone. Not only the screens are different, the motherboards are too (to make the screen work properly). So make sure you get an AMOLED screen first."
The SLCD actually come on in my phone (green lines screen, attached).
Are there different types of digitizers too, for (LCD/AMOLED)? I ask as I have already ordered one from eBay, the same provider.
Also the number you provided seem to lead only to LCDs not AMOLEDs: http://shop.ebay.com/?_from=R40&_trksid=p5197.m570.l1313&_nkw=60H00287&_sacat=See-All-Categories would these work?
AMOLEDs search seem different; http://shop.ebay.com/?_from=R40&_trksid=m570&_nkw=amoled+htc+desire&_sacat=See-All-Categories
Just trying to avoid more unnecessary spending but if you have tried it I will order a new AMOLED..
Regards.

Hmm that is strange, that did not happen with me lol.
Do you now what rom you have on your phone? Do you have a stock rom? Are you rooted? etc, if you still have a old rom on your phone we can try one more thing before you order a new amoled screen.

Lennyz,
Yes my Desire was rooted, can't recall what ROM but I have used the Unrevoked Rooting App and later I think I used [ROM] [29/10] Pre-rooted Stock Froyo (2.10.405.2) [Optional mods]..

Which is the correct one?
Please let me know..

No there is only one type of digitizer for the desire. The one you ordered is the correct one.
The number I provided is AMOLED.
P/N: 60H00287-00P ( By Samsung )
The seller just labeled it differently. If you look at the picture you can see a tiny Samsung logo.
All these are AMOLED.

This one is a SLCD. P/N: 60H00443-03P By Sony
Samsung = AMOLED
Sony = SLCD

Great, thanks..
Now I'm even more confused! please see attached pic of both the back of the box the Desire came in and the tag at the back of the original display.. all indicate that my display is actually S-LCD not AMOLED and if so why isn't it coming on?
Sorry to be a pain, couldn't do it without your help..

That is really strange, are you sure your plugged in the connector properly? You indeed have an SLCD.
In your first post you said that your screen went going crazy after 6 months. What do you mean by this? What did your screen do?
I hope we can fix this.
btw, you don't have your broken digitizer plugged in do you? If so unplug it and try again.
And delete your picture of your box, it displays your IMEI etc, it's better if no one else has this

Lennyz,
Guess what -don't laugh- the display I purchased is an AMOLED by Samsung (attached) so it is the other way around; I purchased an AMOLED for an S-LCD device!
The initial problem was that my original display started fading the image, very whitish but touch responsive..
Just replaced the original LCD, the phone would vibrate on turn on bot nothing on the screen, I guess I bent/damaged it further in removing it..
What next just get a digitizer?
Thanks..

Haha atleast you know what the problem is. What you need:
- New SLCD screen. Where do you live? I have a spare SLCD left (same thing as you ordered the wrong one )
- New digitizer.
Then you are good to go Let me know how it worked out. Good luck.

this is strange as i have swapped slcd and amoled from one phone to another and they both worked just fine..
not bricked or anything.

Lennyz,
I live in St. Lucia in The Caribbean, it would be great if you can sell/ship it to me, let me know the costs please.
Or I can swap you mine if you need an AMOLED
Not sure why this Desire is acting the way it is, according to fridaycider screens can be swapped and would work..
Will see.

On a Desire?

Yes on a desire . Posted this about a month or so ago . I had an amoled desire with a reboot problem , purchased a slcd desire and swapped displays over and sold the faulty desire with slcd screen in . Both phones worked perfectly as regards of display .
Sent from my HTC Desire using XDA App

Something else must be wrong as my Desire's screen no longer come on regardless of which display is used..
Will continue on trying.
Thanks for your response

Had 2 Nexus One phones come in for repairs, one with a broken LCD and one with a broken digitizer. Sure enough - one is AMOLED and another is SLCD. The mainboards will be incompatible, even though the connectors fit perfectly well. I guess that gets people confused to a great degree.
One of the points of difference at the first glance, even without going into serials and to avoid confusion - back connectors . SLCD will have an extra flex with a plug attached at the back.
I seriously doubt claims that either variant works with the same board. On either Nexus or Desire.

[Q] 7 days banging head with black screen not SLCD tried everything here pls help me

I have 2 desires, 1 motherboard water damaged, but screen is ok and says amoled on the box, it turns on but does some weird and strange things but screen is good,
when i say water damage a bit of condinsation not flooded,
The second one has a damaged screen and digitiser again turns on but screen black and white, on the box for that one also says amoled
I all i have done is swapped motherboard over to make one good desire but i get the blank screen with working buttons and the buzz just as if its been flashed with the wrong rom as the slcd brick, it has the exact same symptoms, so with the help of some fantastic threads here I have a working goldcard, downgraded with teppics tool used unrevoked3 and flashed a couple of correct roms and still nothing, I have swapped motherboards back an forth to make sure i haven;t bricked or damaged anything and they contnue to be the same as before i started, I've swapped ribbons and other bits of hardware around and still the same.
can anyone give me any light or help please its been very frustrating, i also have spent an eternity with a magnifying glass to see if any plugs/ conectors have any problems, still looks like a software issue but i think i have done everything, I have also been able to enable usb debuuging with out the screen, (that was fun lol)
Shoulda just sent it back to HTC
in hindsight i wish i had trying to save myself a few pennys that i haven't got at the moment and with 2 sitting here with different problems i thought to get a good one out of the 2 and pass the other onto some one for spares
the box i'm using the motherboard from hasn't the imei number on it so it might not be the right box, so it possible the motherboard i'm using is from an slcd phone, would there be a problem using an slcd motherboard into an amoled screened phone even tho i've done all the above, and now running RUU_Bravo_Froyo_HTC_WWE_2.29.405.5_Radio_32.49.00.32U_5.11.05.27_release_159811_signed ?

Replaced desire AMOLED screen - Still blank

After dropping my desire the screen had an obvious crack (no crack in the glass/digitiser) and displayed crazy colours from the crack, spreading across the screen over the course of the day until finally going completely blank.
Bought a new screen on ebay, same part number, same samsung AMOLED. Replaced today and the phone exhibits exactly the same behaviour. Switches on, digitiser works to the extent I can unlock and lock the phone, but screen is constant black. After a few switch on/offs the screen showed two green lines at the top and about half way down upon unlocking, that went away after another lock and unlock.
Pretty confident that the disassemble/assemble went ok and I didnt stress any flex connectors or similar... so have no idea what could still be wrong....
As I say, phone boots and can unlock/lock (makes the right noises etc) and is recognised by computer when plugged in.
Could using the phone until the screen completely stopped working have broken the controller or something?
Any input greatly appreciated.....
EDIT:
Just switched it on again, green line at top from keyboard lighting point, then the whole screen went blue on unlock. :S
This sound like a dying something, or maybe just bad contacts? Find it strange that unlocking has an effect....
Might be a bad connection or little shortcut?
Here is an official video on how to assemble and disassemble the device, http://forum.xda-developers.com/showthread.php?t=768535. Don't know if that helps but you can check if you did something wrong in the progress.

Seeing as the part was shipped from my country and had the exact same markings and serial numbers as the part I removed, I dont think this is the issue.
Thanks for the video, will disassemble and clean all contacts later today.
Was mainly posting to see if people had heard of/experienced the same issue, trying to ascertain whether it could be a faulty replacement or if its possible to break the hardware that runs the screen.
A good fake can be hard to tell apart from an OEM part...
So the consensus is that its a fake replacement? Really? The screen seems identical in all markings and connectors, my only conclusion can be it came from the same factory. What market would there be in producing defective replicas of mobile phone components?
Anyway I have sent the screen back to the seller for a replacement.
Any response to my other questions? Is it possible to damage the hardware that drives the screen by using the phone with a dying screen to the point of blank display?
Reading through another thread: http://forum.xda-developers.com/showthread.php?t=933866
Post #6 suggests the rom on the phone could have an effect, is this the case?
Thanks for any input.
Rom couldn't be the issue if you've installed the exact same screen.
My guess would be a loose connector.

Replacement screen worked just fine....
Thanks for everyones responses!
Can you post the link to the seller on ebay, from whom you bought the display?

LCD screen

I broke the ribbon cable for the lcd screen while changing out my touch screen. Mine is the amoled version. Can anyone tell me if you can put an slcd screen where an amoled use to be or do I need to change mainboards also?
Im not 100% sure, but I do not think you can just swap the two out. The mainboard is more than likely programmed for that hardware amoled and not the slcd.
I only think this BC certian stock ROMs before 2.2 will not work on the slcd models bc of hardware issues...1st hand experience lol, thought I bricked my phone
The two screens require different drivers and those are baked into the mobo.
So, no, you cannot.

[Q] What's broken in this situation?

Recently, I took time to replace the screen on my s3. (Just the Screen not the digitizer). After I attached the newer screen, I turned the phone on, theres sound, vibration, etc. But the display is not shown at all. Is it the digitizer that broke? Is it something else that broke?
P.S While I was removing the cracked screen, i accidentally turned on the phone when i was using the s3 phone kit (which was pretty useless imo). Could this have played a role?
Any help is appreciated.
Since the digitizer and lcd are separate parts, a broken digitizer should not cause a blank screen. I have replaced the digitizer on a couple of Samsung phones and the lcd always displayed an image but would not respond to any touches.
Is it possible the lcd is defective?

Sorry for the late response, I was just able to check the forums recently. The lcd was brand new. How would I be able to tell if it would be defective or not? I'll post pictures if necessary.

If you can see an image on the screen, the LCD is not defective. If you can see an image but it doesn't respond to touches, the digitizer could be defective, the phone's motherboard is defective, there is a bad connection between the digitizer and motherboard, or all three.

Does that mean, that I need to buy another screen and test it out? I can't really test out the other parts you were talking about because, the screen does not display any image at all.
Since you can't see an image, it could be the LCD. Is there a repair shop where you could askl them to test your LCD?

I think there is one nearby. Would I need to pay for it to be tested? I don't know if it's still worth getting my S3 fixed because my relative is going to give his note 3 to me since the S5 is supposed to be revealed soon.
I would double and triple check that all ribbon cables and connectors are 100% properly attached / connected before replacing anything else....

Did you replace the combo or just the touchscreen? Did you test it before when everything hooked up before taping it to the bezel? What kind of tape did you use? You may want to post a higher resolution thumb of the area where the ribbons connect to the board.

Nope I didn't test it but I put some tape that is easy to remove so i just removed it checked all connections, nothing seems wrong. I attached some new photos (best quality i can get right now). Also I replaced the full combo lcd+touch. Thanks for the reply.

Nothing looks out of the ordinary in those pics, though I don't see how one can replace the combo without removing the boards. Can you explain that as some step in the procedure might cause this. Instead of guessing too much, let's take one thing at a time.

I can't post links so you can search youtube for "Nexus 7 Screen Replacement 2013 model, replace the glass and fix the LCD - Repairs UK" and that's how I did it. And the thing I know I'm missing is the tape he takes off at min 2:43.

Any revision number on the digitizer? I know that there are different revisions of the daughter board and that if your tablet came with a 1.3 board and you replaced it with a 1.4 board the touch would not work, but I don't know if it is the same for the touch screen

I looked at the clip, and it seems ok, except the emi tape hanging from the frame would not stick to the back of the lcd that way. I don't know that it should make a difference since yours is totally unresponsive to any touch. Same case with the missing one going on top of the touchscreen connectors.
There have been cases with other Asus models where you'd need to re-flash the touch firmware before it works. If the daughter board had been working before you replaced the screen, you can either (1) re-flash a stock rom (444 to be sure) using fastboot, or (2) if you're on custom Kitkat (I don't know about Lollipop), re-flash said firmware following the instructions HERE. Remember you have to have one of those kernels mentioned therein installed for the firmware to stick.
I don't know that the touchscreen version should make a difference since they all use the same rom wih the same touch firmware embedded. Unless the rom contains many versions that would automatically select one fitting your hardware version, in which case you should flash the official Kitkat.
Failing all the above, I'd conclude the touchscreen itself is bad. It's a rare occurrence, but has been known to happen. If you bought it from a reputable seller, you should be able to get a replacement. Don't hesitate to ask if something is unclear. Good luck.
I have the same problem. I bought two digitizers and lcd, and both times the problem is the same. I checked for a rev number on the digitizer, but with no luck. The tape I used was M3 300LSE. Already flashed 4.4.4 stock firmware on Flo kernel, but it didn't work.
I can't believe I bought TWO broken digitizers from two different sellers. I will retry the flash...
I tried to see if there is any recognizable serial number on digitizer, and I explain what I found here: http://forum.xda-developers.com/nex...xus-7-2013-touch-screen-unresponsive-t3035124
I'm sorry I'm posting about same issue in two different threads, i did open the other one cause I didn't see this one...
