[Q] Screen Replacement Issue. Advice needed please - Windows Phone 8s by HTC

Hi there,
I have my friends HTC 8S which needed a screen replacement. Which I volunteered to fix as I have previously successfully replaced the screen on my old HTC One X. However, after following all the steps that I researched, an issue arose where I would part assemble the phone (all cables on the motherboard connected, battery connected) to check if the screen would work and there was nothing, I tried a soft reset to see if that would work, which it didn't. I assembled the phone fully to see if it was maybe a loose connection so if I button it all up tight then the connection will be made but that failed also, I even tried the old screen again, that wouldn't work either! So a faulty screen & digitiser is out of the question.
I was very careful when replacing the screen & to my knowledge I have broken nothing. The phone does receive calls, the buttons do work including the light sensors for the home screen etc.
So I'm pretty stuck & feeling bad as my friend is without a phone. So any help or advice will be welcome
Thanks

.:: HELP Appreciated ::. Universal - WHITE SCREEN Problem...

.:: HELP Appreciated ::.
Hello Tech GURUS,
I returned from a long tour (I kept my XDA EXEC at home) & found that my XDA EXEC has got a problem of WHITE SCREEN!! Nothing is Displayed!!
May be brother's childrens or anyone of my friend accidentally did it in my absence(Sorry I'm NOT Sure). May be they pivoted (Turned) the screen in a WRONG DIRECTION!
That doesn't matter WHO DID IT, But the problem screwed my head & I started to trace the problem.
Symptoms:
1) Only WHITE SCREEN(with LCD Backlight), Nothing Else.
2) Charges perfectly through USB & also from Charger.
3) When I connects it to ACTIVE SYNC, it Syncs fine & I can able to explore the files/folders. Copy from & to the handset memory is also works fine.
4) Tried to enter into BOOTLOADER Mode(by pressing Light+Power+Reset), there also got a BLANK SCREEN (NO LCD Backlight).
5) TOUCH SCREEN detects TAPs & make sounds (Tick Tick), That indicates Touch Screen Working fine.
6) Qwerty KeyBoard Works fine. I don't know at what extent, since I can't see nothing on screen. But when I press a key on QWERTY Kbrd, it sounds Tick.
7) Transfered(Beamed) a CONTACT from my another XDA IIi & found Its accepted the beamed data.
8) Volume Up/Down make sounds (Tick, Tick...).
What I Did:
1) Removed the Battery & re-inserted & tried to BOOT it. NO result, just a WHITE SCREEN.
2) Purposely Tried to Rotate the Screen in Wrong Direction to test the loose contacts of co-axial cable.
3) Lastly Dis-Assembled the whole handset (Removed all parts 100%) & Re-Assembled it. But the Problem remains SAME.
4) Dis-Assembled again & this time I tested the LCD Co-Axial Cable's connectivity from MainBoard side connector to LCD Side Connector. There are 2 Cables which connects to LCD. One is 30 Cores Cable & Second one is 40 Cores Cable.
I Successfully tested 30 Cores Cable(Actually it used only 28cores cable, remaining 2 points at connector are DUMMY) & Second 40 Cores Cable I'm UNABLE to Test Since I lost my patience while connecting my Testing Meter to Hair Line sized cores & in just an 10mm connector got 40 cores!!!
5) Observed all cores which passes through SCREEN ROTATOR BASE Hinges & found there is NO physical Damage or CORE CUT.
CAN ANYONE HELP ME TO SOLVE THIS WHITE SCREEN PROBLEM?
IS IT A HARDWARE BASED PROBLEM? OR SOFTWARE BASED?
IS IT A PROBLEM WITH DISPLAY CHIP(IC) ON MAINBOARD?
JUST CONFUSED & SEEKING HELP FROM TECH GURUS.
THANKS IN ADVANCE.

This seems to be a hardware problem. Check connectors in the display housing first. This unit is quite easy to disassemble.
Before you start, you should have a look in the universal SERVICE MANUAL to check out how it gets torn apart .
If all connectors to the display are right in place, but your display still shows nothing ...open the universal body too.
Folow the steps in the manual

White Screen
Hello, this is my first post. May I first just say how great I think this site is, the guides on here really are useful to beginners.
With regard to the white screen, not sure if this helps, but during dismantling of my various PDAs, I managed to connect an LCD ribbon incorrectly, I kind of forced it in & folded one contact over, resulting in white screen. Disconnected, straightened & refit. Hey presto, works like a charm. Hope this helps.
I had the issue, had to buy a new flat cable
It is rare to actually see the damage to the cable, because the damage is inside the insulation....
Best regards!
On the topic...
Hello!
I have a similar issue with my Orange SPVm5000, except that mine will work for up to a minute after a hard reset before going to a white screen.
If I hard reset pressing the left+right+reset keys, the device shows the boot screen and sometimes ever goies into the initial setup but then all of a sudden it goes white. I've opened up the screen and verified and reconected all connections but still the problem persists. Also I've noticed that its not any action I make that causes it; more like a heat/timing issue. Per advice above, I will check the connections in the body but does anyone have any other ideas?!?
Thanks!
Greg.
I have a similar problem. The story;
I purchased an orange branded M5000 on flebay described as second hand in fantastic condition blaa blaa.
When the phone eventualy turned up it had no manual, the outer sleeve of the box was missing and the wrong usb cable was supplyed (one of those larger usb plugs you usualy get for printers.
I have shedlooads of cables and rely wasn't bothered about any of these problems at the time and went about charging the phone (it was totaly flat)
When fully charged I stuck my sim in and poweded her up the phone works fine in portrate and landscape view but as you rotate the screen so it is inline with the keyboard the screen fades to white about half way.
I contacted the seller who basicly told me the phone is second hand so sold as seen!?!?!?
I have flashed various roms on it to see if it was a software fault but nothing.
I think this phone had been in storage as its battery was totaly flat and incorrect accessories suggest the seller didn't check it before shipping. So I believe there is a problem with this phone that occurs when stored.
Sorry for the long post
Have you flashed any rom or just had this problem ...
my conclusions:
1. If you have flashed a new rom to your universal, try to reflash the original rom, it works for many users.
2. If you havent flashed any rom, maybe its a hardware problem.
2.1 If you just used it in a bad way, (ie: rotate screen in wrong way), dissamble it..
2.2 If you have let it on a heat, weat, etc.. place.. maybe the mainboard got a cut-circuit.
Saludos
I tryed a couple of popular WM6 roms (I forget whitch ones) and returned to the genuine Orange WM5 rom. So I doubt its a software fault.
As far was extreme conditions go the phone was well packaged when posted I will gove that to the seller SO unless the eposure happened before shipping I don't think thats to blame ether.
I think the wire in the swivle joint is failing and will continue to get worse as the joint is exercised.
Try to clear it up..

Sounds like the image could not be loaded completely.
The framebuffer is initialized correctly after cold boot, but afterwords booting into wince fails.
So maybe it's pure software issue (flash content is corupt -> image is broken).
Other possibility: Some region of your flash is damaged (more hardware related).

Looks to me like a typical cable issue. Maybe someone twisted the screen the wrong way!
So this is what i guess at least.

99 % of these white screen faults is a typical cable issue. And you don't have to twist your screen wrong way to have this problem, also.... just twist it too often First you have to see if the device is working, apart the screen.... call the number of your phone see if it is just screen related problem. Broken display cable will leave your device oprational, you just don't see the image.
I know it is "less painfull" for people to think it is a software problem.... (The "it would not happen to me" syndrome ) but sometimes things just brake, and moving parts are most risky...
The fact you don't see the damage is of no importance due to the size and nature of the damage. Don't expect to see broken wires in the cable. And even if you check the cable by you instrument, somethimes it will show you it's ok, but in some positions it will loose contact.
Try a different cable... that way you'll be sure.
Best regards, and all the luck!
"Looks to me like a typical cable issue. Maybe someone twisted the screen the wrong way!"
I agree and luckily, finally paypal do as well.
It is being boxed up to a red faced seller as we speak.
A happy ending for me (speaking to soon?)
i hav the same problem as u "HELLCRUSHER" and i flashed also but was not able to cure
still hav this white screen ..
Found this link for some where selling the screen cable assmebly.

HTC Touch Diamond Screen not responding

Hi All,
My diamond screen suddenly stopped responding. The screen calibration is also not working. I tried a hard reset and after that, it stopped at the screen 'Tap the screen to setup your windows phone'. I am not even able to do that. Any help is appreciable. Thanks in advance.

Try re-flashing a rom, or maybe your touch screen (digitizer) needs replacing, if you do this yourself i would recommend buying the digitizer and lcd together as one, it will make a whole lot easier trust me lol. The lcd screen is easy to break.
Had this problem, too, but since I couldn't get back to stock SPL at that time I put my Diamond into a shelf for about 2 days.
When I then tried to get back to stock SPL the screen suddenly responded again.
So, try to take off the battery for a long time (more than a day) and hope it recovers.
Didn't have the problem again.
Change the Touch Screen

I had a similar problem solved with changing the touch screen since the phone was under warranty I have to revert to the stock SPL and stock ROM before I gave it for service. If your phone is not under warranty you can buy the touch screen from ebay.com with a manual and all required instruments for replacing the same.
This happened to me because I was talking to someone over an hour in a humid place which caused sweat to get into the phone through the speakers.

Solution
Okay, I've just had this problem with an HTC Touch, and I think this works with any HTC that has a "digitizer" rather than an all-in-one touchscreen (I think newer phones have digitisers).
I'm not sure if this will always work, but I've just done it - sometimes the inactive touch screen is "broken" because the layers are stuck together (so the phone can't tell where the touch is, hence unresponsive). With mine, I looked at the screen side on and could see a kind of "oily" patch in the light.
The solution is to get masking/gaffa tape - the very sticky brown one. Stick it down on the screen/digitizer and then keep pulling it off - this pulls the layers from each other. I kept repeating this lots before it worked - and in the end I pulled the top layer completely off (I think you should pull from the top of the phone, as the layers need to be attached at the bottom of the screen/digitizer). Once it pulled away, I gently lay it back down (after panicking!!) and hey presto it started working again.
Good luck!

Putting the phone in the fridge makes screen work!
I know this is an old thread but why does putting the phone in the fridge for a few minutes make the touch screen work? Even if I put it out of a moving car and it cools down, then it works for a bit.
Anyone know why this is and how I can fix the phone permanently?

I think I destroyed my HTC One X

Hey guys,
I think I destroyed my HTC One X. I just bought it a month ago from Ebay, and it worked flawless. At some point the display just turn off. I restarted the phone, heard the sound when it starts and even the softkeys worked. But the Display was still off. After after a few restarts the display turned on for a minute, just to freeze after that and turned off again. The phone was still on though.
However I've read a bit around and found out that it could be a cpu heat problem, which could be true because my phone was way too warm sometimes. So I removed the display and put a tiny little bit thermal compound on the cpu. Somehow I managed to rip off the connection cable to the display ... also I managed to rip off the little black cable near the soft keys. The soft keys still work though.
When I start the phone the starting sound comes, the softkeys blink when I restart the phone, you hear the volume buttons etc. So it seems the phone is fully working. Just the display or touchscreen is damaged.
Some pictures:

So, what can I do?
Do you think I could just send it to this site http://www.directfix.com/product/REP-0063.html and let them repair it? Or did I destroyed my phone too much already?
Thanks in advance.
Well,the top cable is ripped off,you can't do anything at this point.The bottom one just seems out of slot as far as i can tell from the pics.
Basicaly you can send it to the repair shop,but i don't think that you can only change the cables,don't really know what to say...Could cost you some to repair it.
I don't want to only change the cables. I want to use this full repair service:
"HTC One X Complete Screen Replacement Service (Includes LCD & Digitizer)".
So they change the cables and put on a new LCD & Digitizer as far I understand.
But do you guys think they will put back the other cable back in slot too?
Please just answer, do you guys think they can repair it if they put on a new screen & digitalizer?
I don't see why not,you can also contact them and explain them the situation.Those cables are quite easy to put back with the proper tools so you don't have to worry about it.

[Q] Digitizer/Touch screen not fully responding.

Quick introduction. For experience and training purposes I started buying broken phones (LCD, digitizers) and try to repair them. I bought HTC Wildfire S with just cracked touch screen. Bought parts and replaced. When assembling phone back the screen did not work on the whole area, what I mean it was working like partially, only vertical left hand side was working. Like writing text message, R works, then E and T doesn't.
Tried to disconnect the digitizer connector, maybe it was not touching properly, couple times. But that didn't work. It was just working in different places than before. Found here a thread about a problem for different digitizer versions.
http://forum.xda-developers.com/showthread.php?t=1942259
But the thing is I have no idea how to approach anything that these people suggest. I don't know how to replace software, reinstall it or whatever involves soft. I would like to learn too.
If you have any ideas or suggestions please share with me, if not I will just sell the phone back as not working. Thanks

HTC 10 Half of Display Not Working After Screen Replacement

The battery on my HTC 10 was completely shot and needed to be replaced. I'm a careful person by nature and this being my first phone repair, I bought an extra screen just in case something happened getting it apart. Followed a guide by jerryrigeverything on how to take apart the phone, got the battery replaced, everything seemed to go smoothly. When I went to test the display before screwing everything together, the new screen I installed lit up, but the right half of the display only showed as a repeating segment from the middle of the screen. Thinking the connector was loose, I disconnected and reconnected the display and made sure everything was tight: same problem. I reinstalled the original display, which I made sure had worked after cutting through the adhesive before I disconnected it, and now the old display is also showing the same issue.
The touch screen on the broken side of the display still works, I'm able to type PIN numbers and whatnot even though I can't see them properly. Only thing I can think of is maybe the connection actually got some debris or something inside of it? I don't think I damaged anything, as I was super careful, but it was also my first time opening up a phone.
Sorry for the inefficiently worded post. Any help would be really appreciated.
Did you resolve this?
I have exactly the same issue you describe after my screen replacement (with two new screens) Believing the first was a dud.
I have done many screens/batteries on my m7, m8's previously never having a problem.
I'm currently back to running my M8 and miss my 10!
Anyone reading this and has any suggestions they are all welcome!!
Thank you in advance
Exactly the same issue this guy has
https://youtu.be/RpdCuMiTOn8
I'm now wondering if it is just bad aftermarket screens?
Has anyone else replaced their screen successfully, if so where did you get the screen?
Thanks Rory
I have been having the same problem. I just tested screen number 4 that has the same exact problem. Is there a specific brand that is known to test well?
I dropped my 10 in water at work...believe it was a salty water at that. It stopped working completely. I opened the phone to check the internal components for damage and I broke the LCD doing so. I replaced the battery and the screen at almost the same time. I think it may have been a week or two apart.
The battery is still working. The screen worked initially but the phone kept getting really hot and the heat kills the phone. I tried keeping it cool at all times which kept it operational. It hasn't been activated since I quickly replaced the phone with another of my lines upgrades. I went back to the phone to check it out and try using it as a replacement for my daughter but the screen no longer works.
The battery charges just fine...the led light indicates that well. I've tried reinstalling it several times with no success getting the screen working again. I tried the original screen to check and I could see light and it was responding but its not usable so I'm stuck with a phone that has a new non-working display. I think the brand was called DIYRepair or similar.
If anyone has encountered this and has advice...I'd be happy to try anything.
