[Q] New LCD and Digitizer DOA?? Help please!

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.

Did you ever get this taken care of?

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:

If you did everything correctly it could just mean that you prob got a faulty part

[Q] Need help with blank screen after replacement

Hi all. I'm having an issue with a 727R. I replaced a broken screen and now can't get the screen to stay on. Its a non rooted, factory 2.3.5 phone. When I turn it on, the sghi-727r screen pops up for several seconds and then dissappears, phone vibrates once, notification sounds appear shortly and all touch functions appear to work (by sound and haptic feedback). For all intents and purposes, this phone is on and working perfectly...if you're blind lol. I know the replacement screen works because it works perfectly if I go into download (odin) mode. I've been searching threads and haven't been able to come up with a solution, as most of the other blank screens are from bad flashes. Keep in mind that I am also testing this with the casing removed as it is a repair for a friend (if that makes any difference). Any help or ideas would be greatly appreciated and thanks in advance.

Is the brightness maybe turned ALL the way down? When it finishes booting shine a flashlite on the screen and tell me if u can see text, icons etc...

I'll do that as soon as I get home this afternoon. I could only hope that's all it is, but i'm a little skeptical that I could be so lucky. forgot to mention that I have also odin flashed the stock rom back on just in case of software corruption. I would also think that I would get full boot logo's during the boot sequence, but hey!....its definately worth a shot! I've seen stranger things . Thanks for the quick response.

No worries, keep us informed. I didn't even bother to ask because I just assumed someone at your level who can change a screen would intuitively know to Odin stock... I was right :good:

So you had display for start of boot and d/l mode? If so, then I'll go no farther until I get another replacement screen.:crying:. Come to think of it, when plugged in and off, the charge symbol shows up for a second and its discoloured (almost like its made of vertical lines that are pinks and grays). You may have just saved me a lot of time. I was leaning toward trying to adb error logs in hopes of finding something. Other than that it was going to be a reflow on the gpu since the phone did do a leap of faith from 6 ft up....and lost lol.

No dice icenight. Tried out of hope but its completely black. I was really hoping for maybe a fault that could be fixed with a flash.....whoa is me....looks like I may be sending screen back and getting another. I cant send it out for another day so if anyone has any other ideas, or wishes to guinea pig this unit until one comes in, feel free to chime in. And thanks for the responses so far!

And the winner is....Crashpsycho! After months of trying to find a replacement, i finally got my hands on two of them for a decent price. Popped one in, odin'd jb stock and voila! perfect phone again. Thanks Crash!

[Q] Screen drop outs and now always black, why?

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.

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

[Q] Broken digitizer/LCD and I need files

Hey,
Its been a while, but i dropped my infuse from a pressbox and it fell many feet to the concrete ground :/ The screen glass itself isn't cracked but the underpart of it is (LCD itself most likely). Im not getting any screen interaction or visibility at all....It is rooted and running a custom ROM but i can't remember which. I would love to get as many files off of it as possible. It still works for sure though. I can hear it get some notifications and the backlit bottom keys light up and still respond. My hope is that someone has a good suggestion for me.
Ive got two possible ideas at the moment:
A) Somehow blindly use CWM and get it to mount USB storage to get some of the files off of it.
B) Buy one on craigslist and replace the motherboard. (Sounds reasonable....I've already taken it apart before so it shouldn't be hard.....but don't know if it would work...)
So......
A) Do y'all think either ideas would work?
B) Can you guys show me some shots of the CWM mounting usb process and i could see if i could do it blindly?
Thanks y'all

The same thing happened to me. I went the craigslist method. Replaced the motherboard and it worked like a charm!

Nexus 5 black screen

My N7 4.4.2 Not Rooted has been playing up lately. For the 2nd time in 3 days, I picked it up and it wouldnt respond. I could hear the screenshot being taken so the phone was on but the screen was black. It vibrates after using the power button and it finally boots up again. The phone has been perfect for about a month and this error only started recently.

Do a factory reset. Keep in mind that this will wipe your internal storage so be sure to back up and data, photos, etc. before hand. If that doesn't fix it then flash the factory image over. As to how, refer to this thread.
Your problem should be fixed after the Factory Reset though. Good Luck!

Thanks. I was hoping it wouldn't come to this but oh well. Is there a cause for this?

Were are talking about the N5 right?. I had this issue with my G2X a couple years ago. It turns out that after I took it apart the flex cable looked like at had been torn a tad bit. This sounds like a flex cable problem. Software could be the issue and a factory reset may help. However in my experience that's usually a flex cable or pop connection. Send it in if the reset does not work. Don't bother trying to do this yourself. It may be the front panel flex cable. Or the pop connection of the main board. When these cables are made, they are literally thrown into barrels and sent to The front panel assembly line. So chances are. One of these flex cables suffered some damage. Same goes with the tiny connection on the main board. These tiny pieces are put on one by one. I think robots do it. The device turned on for their tests. But the long run? ...Well you get the point.

Im just facotry resetting my phone right now, i'll post later the results after a few days of testing

Well? did the factory reset work? I have this issue and it's driving me nuts!!!! I read somewhere that squeezing the case helps, and indeed this seems to work something, to it looks like hardware issue to me

black screen nexus 5
I was totally desperate with this random black screen. I tried everything including change of flex cable and also screen, but the same random black screen
I changed the 2 years old battery with a new one and.... ooff... this resolved my problem .no black screen anymore
I hope that, with this solution, I give You another direction of thinking about what is causing this annoying problem
