I run a cell phone repair company and we do quite a few repairs but this in particular HTC One X has us all stumped here. We do realize that there are 3 different versions of the dig/lcd and we have the correct part. But has anyone had problems with trying to replace the HTC One X dig/lcd assembly. It seems that after I put the new part on the lcd is black but the phone is still on. I even went back and put the old screen back on and it is still black. Prior to the repair the lcd worked fine. But just the digitizer was cracked. I have even went as far as changing the motherboard on the phone to a new one and am still having the same issue. Any help would be greatly appreciated!
Have you checked the ribbon length to make sure you do not have a break?

It would seem to me as though it's just as simple as one of the connectors is not plugged in or just not plugged in properly, which is easy to do since one of them is on the underside of the board which I believe is the one for the screen itself.

OP already stated that going back to the original LCD did not yield results.

Exactly. Seems like the only probable answer is that something was broken during teardown - either a cable or connector. Given the size of everything in there, it doesn't take much....
Did you ever find a solution to this?
I'm kind of in the same boat at the moment, BUT there's a silverish lining
In the midst of replacing a screen on my One X. Phone is obviously "on" (despite being in pieces on my desk), but n either the new or old screens will come on when I push the power button.
For a lark, I plugged the phone in, and did an 'adb reboot'
My splash screen comes up on the new screen just fine, as does the Viper Logo and my home screen and everything.... but once it shuts off the power button will NOT re-wake it up. At first I thought "I must have broken the power button" but I also forced a notification to it - which also typically wakes up the screen - and also saw nothing.
EDIT : Cancel that; for some reason the power button didn't work until I had the case back on. Grounding maybe? Either way, working fine now.
Some Ebay product page for a screen replacement said you should first power on the device with the old screen, then take the old screen out while the phone is running and put the new one in.
Maybe you should trie that. I'm not a hardware expert, so do some research before trying this and don't blame me if it doesnt work
That will only work if the screens not working. Op. It's difficult to narrow the issue in your situation. If the flex cables don't work, it's a short which would require much more advanced knowledge to fix.

So i purchased a LCD/digitizer from eBay and received it in the mail this morning. I followed the steps and was able to get my cracked screen (digitzer&lcd) off. After assembling it all with the new screen i ran into an issue.
There is no response from the screen at all it is just black. The phone boots fine though because it vibrated and then a few minutes later i can hear my notifications go off and the led is flashing.
could it be a bad connection with the wires, if so what one should I look at, Did i buy a faulty screen, or am i just sol?
is there any difference between a One X and a One XL screen?
any help is appreciated.
purchased from here: http://www.ebay.com/itm/271006361868?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649#ht_2923wt_1218
Could be bad connection..there is a YouTube vid on replacing it..
Sent from my HTC One X using XDA
yea that is what i am assuming since nothing was working but i just wanted to see if anyone else ran into this issue :/
I've successfully replaced the lcd/digitizer on my htc one xl, and gonna be doing another one soon. Make sure the connections are fully clamped in place. the top connection closest to the htc/at&t logo on the screen controls the touch, while the bottom connection controls the picture. So just see if the bottom connection is damaged or maybe out of place. If nothing is wrong with them then you may have a faulty screen. I suggest always testing the screen before actually putting everything in place with the adhesives, so just connect it first and if it works then you can reassemble everything.. I'm not too sure whether there is any difference with the htc one x and one xl screen. As far as I know they should be very similar. But I would definitely stay on the safe side and get only the screen that is made for your device. I have not attempted using one with the other.
So I ordered a new LCD and digitizer from new harbor via amazon.
I took the phone apart, installed the new array, and powered it on, and the screen is great (maybe even brighter than the last one) but it just has zero touch input.
The last screen worked fine, but the LCD was broken. I could have it acknowledge touches so I dont think that the motherboard or anything else is broken, so I wonder what may have went wrong.
Should I take this mofo apart again and see if I have a loose connection? Maybe the ribbon cable is not connected right?
Probably the past is DOA?
Help please! thanks.

Is this somewhere in the service menu? I can boot into its custom menu by holding down volume and power... Not sure if there's more to it.
It's rooted s-off so I get menus to get into recovery or fast boot etc

Scratch that. Just re read your post. "Zero touch input". It's an option in the rom.
There are a few threads/posts where people have replaced the screen, either here or the dhd forum. Check what they had to say. I have absolutely no experience in that. Perhaps it's a cable as you said, but before doing that, I would research on it first. You may end up like me with 9 screws left over after taking apart my ps3 three times (screwing it up even more).

Removing and taking it apart isn't a problem. There are only eight screws.
This isn't fun... To be certain.

Just replaced mine. LCD intact. Touch no longer working. They aren't kidding: this phone isn't fun to work on. It's a *****. I've repaired a half dozen iPhones. This makes that stuff seem rudimentary.

I've had my inspire apart several times. Other than removing the Flash/GPS, and separating the LCD from the frame its quite simple. If you want a pain try a slide phone.

Understand your pain because just recently I had to change my entire screen for my Inspire 4G. I assume that you did everything correctly but here is the video that helped me on youtube:
HTC INSPIRE Screen Repair and LCD / DIGI REPLACEMENT from phonedoctors
If you did everything correctly it could just mean that you prob got a faulty part
Hi guys,
my DS did some strange stuff lately. It began with the screen staying black when I woke it up (hardware buttons did turn on and touchscreen also worked). I thought it was a software issue, because after a few on and offs the screen usually worked again. Also, this never happened when the phone was charging.
But a few days ago the screen never turned back on again, even when charging. I got a new battery but still no change. It won't even turn on when booting or when going to fastboot/ hboot.
Does anyone have an idea what is broken? I think my best guess is to have a look at these other screen replacement threads, but I wanted to ask first because the screen seemed to have gradually become broken, which confuses me. I didn't think something like that was even possible. Also, I can't return it since I bought it used and in Germany (DS is USA exclusive).
Thanks for help
Most certainly hardware as it is black when in bootloader and ROM. Best guess is the LCD but could also be the main flex the likelyhood of any thin else is fairly small.
Do read up on the screen replacement threads as this phone is one pain in the ass, you also need to be aware of what LCD to buy as there were different ones and they are not compatible.

Thanks for the tips. Screen might be still ok since it went out gradually, could be a defective contact since it also went on and off randomly. But I guess there is no way to only replace this contact, too complicated to find out... I will see.
Yeah, I had a look at these threads already, thank you
I had a program that I moved to the sd card that would cause the screen not to come on and would have to do a battery pull. When I moved the app back to the phone, the problem stopped.
(Walgreens app)
It has happened again since, so it may be another app I have to track down. Or I may be looking at faulty screen trouble too.
Sent from my MyTouch 4G Slide using Tapatalk 2
even if an app on sd were the cause of this it certainly couldnt make the screen blackout while in recovery and bootloader mode. to the best of my knowledge it has to be a hardware fault if screen wont turn on in bootloader... but well ive been proven wrong in the past
Well since I had problems with the screen turning off before when it did work in recovery, there might be a connection to daswerk's case. However I kept all my apps on the internal SSD and do remember checking it. Also, my screen turned back on sooner or later or when I played around with the keyboard.
However later it was off even in recovery mode. I did disassemble my DS lately (and broke my screen like seemingly everyone else hehe) and am now waiting for my new LCD screen to arrive in Germany from the states haha. Shipping costs were higher than LCD costs, d'oh! Thanks again demkantor, you've been helping me indirectly with your posts in the other threads as well
So guys, screen arrived, reassembled my phone, switched it on aaand... black screen.
Graphic chip or motherboard may be broken. I'm thinking about a loose connection because screen turned off once in a while before it never got back on. I found a user by coincidence here on xda who reported the same problem.
Any ideas are greatly appreciated. Don't want to forsake my dearly loved DS :'(
Next most likely would be main flex cable

Are there other possibilities as well? I'm thinking about getting a whole replacement set so I can try everything shipping costs are high since I live in germany hmmf
btw, digitizer/ touchscreen doesn't seem to work either, is this another sign that main flex cable is the prolem?
There are always more possiblities I was just letting you know what I would replace next as the most likley cause.
Having multiple phones to exchange parts is a good idea and really about the only way to test different components
And yes have no digitizer working can be a sign of a bad flex as well

So i am replacing my one x lcd screen.. bought the whole lcd and digitizer since looks like a pain to just do the digitizer.. i got the old one out, put the new one in and power up.. phone vibrates, but i dont get any sounds and no display on my screen.. i have check all my cables too many times, reseating each one, trying everything.. the other thing is once i push the power button to turn on the phone, it vibrates, makes no noises, but if i hold down the power button afterward, the softkeys start flashing several times.. do i just got a bad lcd or is it something more?
none?

Sorry I meant to reply to this yesterday but forgot lol
You need to sync your new LCD.
How do I do that? You may ask.
Plug your old LCD back in, dont put the phone back together, turn the phone on, while it's on, switch LCD's to the new one.
If I'm not mistaken, that should do it. Post back and let me know.

Good Luck. I would assume if you asked on here you would expect to hear an answer you didnt expect or you'd have thought of it
But yes, there are 3 screen types from 3 diff makers. So if you bought a different one, you need to sync it or it will appear to be off. Digitizer will still work.
1) Green Flex (Sharp)
2) Green + Yellow Flex (Sony)
3) Yellow (AU)
try this one http://www.etradesupply.com/oem-htc-one-x-lcd-screen-and-digitizer-assembly-with-light-guide.html
Do instructions exist or are there any hints for the removal of the existing screen?
Videos on YouTube.
Tip: Keep track of where all the screws go. Have unlimited patience. Stay organized. Minimize distractions while working on it. Heed my screen sync post above.

yeah, i followed the video instructions exactly. and youre right, i posted here to find solutions i never heard of or thought of. as far as syncing with old screen i am SOL on that one.. i sent it back today, and ill try out the new one. post my findings here and i am hoping its just a DOA screen and not the phone itself. thanks for the responses.

We have synced the old LCD, installed the new and the screen looks like white noise on a TV screen.. We have tested this LCD in a functional unit and works fine.. Is this a board issue?

Sounds like it, but you may want to test another screen with that board just to be safe. I haven't tested extensively the results of mix and matching screens with different boards.

Then the GPU is most likely at fault which is built into the board. New board needed. As for the fast response. NP, I live here.

Hey guys.
I have an SGS2 Skyrocket that boots but nothing ever shows up on the screen!
I held the power button and it does in fact boot the samsung logo never shows up.
The keys at the bottom light up but still nothing.
Seeing that everything worked i booted the phone into download mode to see if it would fix it (i still couldnt see anything, i was just going off of the vibrations)
So I decided to go ahead and flash back to stock GB from odin.
It went through successfully and it booted my phone back up.
Still nothing showing up on the screen...
Can someone please help me?
Sounds like a broken/cracked/bad LCD or digitizer problem.
Was it dropped? Left in direct sunlight? Leaving it back pocket and sitting on it? ...
So seek out a new LCD replacement. From your thorough explanation (awesome description of the problem!) It sounds like your logic board is fully functional.
So you should be good to go with a new LCD which runs around $100+/-$10 but check both eBay and amazon. And watch some youtube videos to see how the phone teardown works or pay a little extra to a repair shop to get it fixed.

It indeed sounds like you display is shot. If your phone is under a year old Samsung will replace it for about 160 bucks. If not then you can do it yourself. Here's an excellent photo write-up for the procedure:

The last one had cracked and i did replace it.
When i had turned it back on it was like this unfortunately.
Could it be a Hardware failure or something with the motherboard?
