Last night I was out and during the night I pulled my desire z out of my pocket to find that the screen was dead, the soft touch buttons were still lit up and working but no display. I pulled the battery and tried to reboot and no luck, you can hear it booting and even unlock/receive calls and txts etc once it has booted up just the screen stays blank the whole time so have to do everything on feel.
Essentially does this just mean my screen has a hardware fault? is it worth trying to fix? I assume the only option would be to purchase a replacement screen and dissemble and reassemble it?
(warranty is not worth it as I live in New Zealand and would have to send my phone back to the UK where I bought it from, also I have dropped it quite a few times so probably voided anyway...)
Thanks in advance for any input
Does it never display anything? So not even a flash during boot or something?
Because then it is probably a hardware problem.
Since the soft touch buttons do still work I think there might be a little crack or something in the flat cable that connects the bottom half with the top.
Maybe you could check whether you can see if the cable is broken or not?
The best thing to do then is to look for a replacement and try to fix it yourself or bring it to a shop where they can do it for you.
No it never displays anything, completely dead the whole time. The touch input is still working though as I answered a phone call this morning on it by making the usual gesture just without being able to see anything. Doesnt seem to be anything wrong with the cable itself as far as I can see. Yea might have to get someone to have a look at it.
My phone is acting the same. I dropped my phone in the pond before, but pulled battery out on time and had it in rice for a day. My phone was still working for about two weeks after that incident. I dropped it and had one little crack at the top of the screen and about a week after that it died when I had a water balloon fight with the phone in my pocket. D;
Do any of you know if the replacement lcd screen/digitizer for the Desire Z would work for the G2?
I had the same thing happening to my G2 screen, only it was intermittently working for a little while, then just completely died and wouldn't work. It was doing this crazy flickering thing then the back light wouldn't go on at all. If I held the phone at a certain angle in the sun, I could see that the pixels were indeed working on the display, but there was no backlight to make them normally visible.
So I purchased a replacement screen from ebay and carefully followed the directions on a youtube video for a G2 take apart. Its not a hard task to take apart and get down to the screen itself. It was rather easy. After putting it back together the screen still didn't work! Sounds work, i can also receive calls etc. But the screen still doesn't work!
Is there any way that this could be a software issue?
Oh and PS, I believe the LCD replacement would work for both the desire Z and the G2. They are identical phones after all right? I'd say its a safe bet. The screen I bought was only 35 bucks. Didn't think that was a bad deal.
Another dead screen or something else?
Few days ago my phone fell of the couch onto a rug - no big deal, so far it has survived much worse, but when I picked it up, the colors were all messed up - overly green and red. Tried restarting - no luck. Everything worked fine, except the colors, but then the screen turned of completely. I could hear notifications, phonecalls, but the screen was dead. After some tapping on the screen, it turned on again - with ****ed up colors. Then started flickering and was gone again. Few more times I could turn it on by tapping before it was dead for good.
Figured, after all these drops it survived, maybe the screen connector is a bit loose. I mean, I could sometime get a contact when tapping it, so I dissasambled it completely, secured all the connection, put it all back tougether and fired up - same thing: dead screen, phone working.
Has anyone had such problem before? Is it screen that is dead, or connector or... I have no clue... I would like try to fix it on my own, with some replacement parts I could get on ebay - but, what gave?
Hey guys, I cracked the screen on my HOX so I replaced the screen with a unit from directfix.com
After double checking all of the flex cables I tried to power the phone on and I am getting nothing from the screen and the vibration motor is constantly buzzing.
The only signs of life is the red LED, the three capacative buttons will light up, and the aforementioned constant vibrating. If i hold the power button to attempt to turn it off the buttons blink several times then it seems to stay on after that.
Has anyone heard of a problem like this before? Its killing me not having my HOX! I had to put my sim card in my old iphone 3gs and I have to say that this sucks really bad.
Are you sure you've connected everything correctly? It sounds like there's something being shorted! I'd recommend you to dissassembly again, an assembly again BUT THIS TIME VERY CAREFUL. Best is if you use a video tutorial if you think you're not experienced enough.

Thank you for the advice. I disassembled the phone and carefully put it back together. I took care to make sure the flex cables for the LCD, vibrator/button strip, antenna, volume buttons and digitizer were all carefully connected.
Now the vibrate function seems to work fine as it just gives me a short pulse when I turn the phone on as it usually does. The screen however, still refuses to turn on. I made extra sure that its flex cable was put in the right way and that it was secured with the jaw bone connector.
This video here www youtube com/watch?v=OIeO0DueMcg&feature=youtu.be at about 6:00 shows that you can test the LCD midway through the assembly process.
I tried exactly that and the LCD would still not turn on. I am just hesitant to return it because I know that the chances of the screen being a complete dud are very slim.
Now when the phone is turned on the three capacitive buttons remain on which I know didn't used to happen.

Update: So I was thinking the phone was booting up all the way, but I just saw that my computer won't recognize the phone beyond making a connection sound; I just can't see it in windows. As i said the capacitive lights stay on, but if I fold the power button they blink 15 times exactly and the phone seems to power off. Should I assume the SoC is dead or gamble with a replacement LCD?

Hi, I'm in the exact same situation you have described above! Did you ever manage to work it out, what was the solution? Any info or help at all would be great, thanks!!
I did replace my lcd+digitizer as well as yous. And I had same problem. But it does work now.
1.open up your phone . Take all parts off, separated.
2. Take battery off.
3.Now connect power button.
4. Connect battery.
5.Switch it on (hold pwbt for 2sec), mobo+battery+power button itself.
6.Now wait 20 sec.
7.Now connect LCD ribbon(bottom one),make sure it's right in, push it in far as you can.
8.Now put it righ on bezel and connect digitizer ribbon.
9.Press pwbt and see does it work. If does put rest of stuff together and be happy.
I can make phototutorial on request.
I did it few times. The battery was touching the LCD ribbon and it comes of very little but screen comes off and I have to start all over again.
So make sure that ribbon it's not getting any pressure from battery.
Let me know does that help.

I have the p600, bought at Best Buy a few days after launch. Have it rooted using auto root. It has been running perfectly until today. It started taking a few presses of the power button to turn it on after the screen went to sleep, I thought nothing of it and assumed I was just not pressing the button hard enough.
Then a few hours ago, it just stopped turning on again after the screen went to sleep. If I power it off (long press on power button) it will reboot and the display is on again, and it works fine until it goes back to sleep.
After pressing the power button, the menu and back button light up, and If I hold the tablet in a bright light, I can see the images on the screen. So I know the LCD is working, but for some reason the back light won't turn back on after going to sleep. If it were a bad back light, then obviously it wouldn't work again after rebooting.
I tried a factory wipe - same problem
I did an Odin flash with MK1 stock rom - same problem
I suspect a hardware issue, but Ive been reading about this "sleep of death" that can happen with android devices. Fixes range from installing new kernels to replacing the device.
Anyone experience this or know what is going on?
**UPDATE**
A possible fix for this (and it worked for me) is to take the back cover off, disconnect the battery, and plug it back in again.
I have included pictures of what you are looking for.
When taking the back cover off, I was able to do it with just a credit card. Start at the charge port and carefully get between the casing at the cover, move around the outside, popping the outside clips (look at the photo of this). The inner clips will still be holding after you get all the way around, then simply work out the inner clips 1 at a time. It was a little difficult the first time because I wasn't sure how it was attached, but the second time I took it off, it was pretty straight forward.
When putting the cover back on, follow the same procedure. Start at the charge port, get those clips in, then work your way around the outside, careful not to push to hard on the inner part of the tablet, apply your force at the edges. once the edges are clipped in all the way around, simply press in the inner clips (you will feel them snap in)
I can post more pictures for people who want them. I might even make a short video of the procedure, all in all, its pretty straight forward. It's a relatively easy cover to remove.

Interesting.. I just received my p600 today. I had an occurrence similar to this - I hope there isn't some flaw in them we are uncovering... I'll have to wait a week or two before rooting to see if it occurs again.

ya, good idea on the root. Im not sure how the warranty bit being tripped is going to play out should I need a replacement given that we don't even have custom kernels or rom's yet.
I am going to downgrade the firmware to MJ4 and cross my fingers. Wish there was a faster way to DL these other than slow ass sammobile lol.
Had the same issue on my 10-day old device during a flight back from the US to the UK which was highly inconvenient.
Anyway, what I noticed was that when opening the magnet cover or turning on from sleep, the tablet actually woke up (touch buttons lit up) but the screen backlight wasn't turning on (if I held it at a certain angle, I could see that the screen was showing the home page but just no backlight).
Another side effect of this was that, even after rebooting and having the screen backlight on, the brightness setting was doing nothing.. I could set it to auto or manual brightness and adjust the slider and it stayed the same brightness regardless. As with others, a factory restore had no effect.
In the end, given that I'm kind of boned for the US warranty living in the UK anyway, I just opened it, disconnected the battery connector, reconnected it and started it up. After that, no problem.. brightness and wake-from-sleep started working again no problem.

I am using the the bookcover also, wonder if the magnetic cover is somehow screwing it up. Im glad you said you opened it up to DC the battery. That was on my list of things to try! too bad there isn't a way to DC the battery with a USB jig. cross some wires or something.. as a EE, one would think I would know a trick that would accomplish that.. lol.
im downgrading firmware and going to do a full nand-erase with bootloader update, and see what happens
*Just noticed that my brightness slider also has no effect. This must be the indicator that the sleep of death has occurred
*Update*
I removed the back cover, unplugged the battery, plugged it back in and it started working normally again. After playing with it for several minutes to ensure it was working (turning it off and on a few times over and over) I put the rear cover back on. But as soon as I had done that, the problem started again.
I removed the cover again.. unplugged the battery.. but this time, after plugging it back in, the problem remained. After a few more unplug/repluging of the battery and it not working, I decided to unplug the LCD, digitizer, and the backlight ribbon cables. I booted the device without these attached, let it boot fully, then powered it down, removed the battery connector, re-attached the ribbon cables then the battery, booted it again, and the screen was back to normal.
Ill keep playing around with this to see if isolate the problem, but it seems like there is something going on with the connectors, or some sensor/detector/controller getting "software stuck". When the screen is turned off, this sensor/detector/controller is either not getting the right information sent to it, or, it is has gotten stuck in some process it can't resolve (happens a lot in hardware engineering). It can happen when something shorts, and sends the device into a shutdown state (watchdog trips). The rear motherboard has A LOT of flex to it, and I had to push kinda hard on the rear cover to re-attach it. I wonder if when the back of the tablet gets pushed in just the right way, in just the right spot, it causes this screen issue to happen.
Either way, this is pretty unacceptable for a $600 device. The good news is that there is no warrant seal on the rear cover.
After use auto root. did you reinstall stock recovery?.

If you open it again, would you mind taking a few pictures of a disassembly process and the way it looks after removing the back cover?
How difficult is it to remove the back cover? Any plastic damage caused?

Already took em That was the first thing I thought of when I was taking it apart. I will try to get them posted soon.
Tablet turned on and off like normal yesterday and today. Not a single forced reboot was required. However, while taking notes today, I noticed a dead zone on the right side of the screen. Touch works fine there(with fingers), but the spen won't work. It just jumps over the area. The affected area is a vertical line from top to bottom.
Since I have not been using the spen lately, I can't be sure if it is a symptom of the sleep of death, or a result of removing the ribbon cables and not seating them properly when I reattached them. I'm going reseat the cables and see what happens.
I just got my Note tonight and have this same issue. I got it at Amazon and it came with both seals broken as others have found. Was surprised it seemed to already be on, when I hit the power button the buttons lit up but no screen. Grabbed a flashlight and could see the backlight wasn't turning on. Tried turning it off and back on, or so I thought, but no dice. I figured I had a bad unit and set up the RMA with Amazon.
I then went and stuck it on the charger and held the power button for a long time, and the charging screen popped up. Turned it on, seemed to be working fine until I hit the power button, and then the backlight wouldn't turn back on again until I rebooted it. I took all of the updates and did another factory reset, same issue.
Now, I also bought a smart cover. After taking the updates but before the reset I tried it, it'd shut off the Note but the backlight still wouldn't turn on when I opened it up. HOWEVER, after the factory reset, I opened and closed it a few times and it worked correctly. I then tried the power button a couple of times and it also worked correctly. For the record, my brightness controls DO work correctly.
At this point I'm not sure what to do. I _really_ want this tablet, and Amazon is out of stuck so I can only return it for a refund. I don't want to do that since I got it on sale and it no longer is.
EDIT: Also, I just tried closing my smart cover and hitting the power button with the cover still closed, and the screen DID turn on. So I'm not sure if that partially throws the theory of the magnet going out of whack out the window or not, since it should turn on even if the cover is closed.

I just checked Amazon and they have them in stock. Do you think maybe because so many people are getting replacements over and over they are just recycling them and selling them as "new?" Do you have the link to where people are reporting getting them with both seals broken? Thanks.

Hi Serinety:
Thanks for the diassembly picture. I believe you are the first one to show the inside!
If possible, do you mind showing pictures a bit more inside? For instance, I'd like to see where the WiFi and LTE connectors are. (They are both different connectors btw)
Many thanks.

Thanks, can you help me?
i just drop my p600, all the digitizer is broken now, but its still working, i dont want to tear down it, because it can stop working, so, can you please tell me if the digitizer is atached (glue and heat) to the screen, or is it just a plastic holder as its predecessor note 10.1?...
thanks buddyes, sorry about my english it is not my main lenguage u_u, im trying my best.
Just repaired my daughter 's note 10.1 2014 further hard fall thanks to your battery advice!
Thank you, it works fine

Just someone post the images of rear back of Note 10.1 (2014) for both P601 and P600 to see the diff when Disassemble the P601 and P600 for replacement purpose?
(mine is P601 and i think i need replace SIM card holder-it's broken since few times take it in-out).
This thread freaks me out. I hope this doesn't start happening to me/everyone.

Taking into account the shock of impact, it is normal to my opinion to have strange behaviour of the device...
Would be better to have full time access to battery in order to make hard reset ... or to have dedicated button for this purpose.

Hey all, so I just replaced the screen (followed the great guide on this site) and now I'm getting some odd behavior when trying to boot.
The power button is completely unresponsive. When I plug the phone into power, the LG screen comes up for ~3 seconds, as normal. The LED is flashing thru all the colors per the usual as well. Then the screen goes black for another 3 seconds, all the while the LED flashing. Then LG pops up again just for a moment, then to the normal phone-is-off-but-charging screen, with the LED flashing red.
Really don't know what to make of this. I had it rooted with a one-click root from here. The only changes were deleting stock apps and enabling the front touch keys (but never had an issue with it booting after this, I did that at least a week ago). Also my PC recognizes that something is plugged in, so I guess that's good.
Thoughts?
Update: tried booting into recovery mode, I held the buttons for much longer than normal to no response. As soon as I let go, I get the LG screen. Then black. Then LG. Then an unusually long AT&T screen, then it booted. Now the power button works as it should, and it boots in that same odd fashion. And it seems that I can not go into recovery. Yikes.
I'd be fine with that except I have a dead zone across the lower portion of the screen, it's about a half inch tall and about covers the asdfgh... row of the keyboard. Weirdly if I start pressing on any other key and then swipe to any area in the "dead" zone it WILL register, as in, I can select the S key, normally in the dead zone, but swiping to it from a working area. Will try soaking the mobo in alcohol and swabbing the digitzer connector with a q-tip. Any other thoughts?
Update 2: I tried cleaning the contacts of the digitzer connection- both the end of the cable and the motherboard connection- with rubbing alcohol. Reassembled, and we're back to square one. Power button unresponsive, when plugged in I'll get the LG screen, then black, then the LG screen will flash and I'll get the chargining screen. But now, trying to boot into recovery mode does nothing. So then I soaked the mobo in alcohol, and cleaned ALL the contacts and ribbon cables on the frame. Reassembled, no change. I really hope someone sees this, as I'm at he end of my tech know-how. Tonight I'll try to reconnect my old touchscreen and see what happens. Maybe the new one is just defective? But you'd think the phone would still turn on...
God I hope somebody sees this. I feel like a complete nut talking to myself.

Hey all, so I just replaced the screen (followed the great guide on this site) and now I'm getting some odd behavior when trying to boot.

Okay sounds like a hardware issue with the power button being unresponsive. I would take the device apart look around all connections of the power button and look for any hair line cracks or dirty, sticky, grimmy connections. Try cleaning upall that stuff, while there I would look at the digitizer and clean that up. When done flash a new rom with the LG flash tool, allow boot and reboot normally several times before testing. I hope this helps I am new to the phone and have yet to get my repair kit for it so I will not know much more about it till I get into it myself. Hair line cracks can be easily fixed as long as its on the sadder areas. Just re sadder it

Now for the weird flashing on and off booting mine does this as well but all functions regardless are working flawlessly. My phone will need serious structural repairs but nothing I can't do just had a horrible owner. Definitely worth the trouble this thing runs so smooth better than any other I have used and it will continue to hold for a couple years cause of the power behind it. I wouldn't worry about the booting flashing like that I'm just thinking it does this to show it has been tampered with.

Hey man thanks for your reply. Reminded me to update this for anyone else who finds it.
So the new screen was definitely defective. The one time I managed to get it on there was a dead spot. I sent it back, a replacement is on its way.
Now the good news- I realized why my phone wouldn't boot. Turns out that when removing the motherboard, the top part of it got a little... bent. Nothing bad, nothing permanent, but when I mounted back onto the housing, the top part of it had a tendency to stick up a little bit. Well if you follow the small ribbon cable off the power button, it leads to two gold contacts. Sure enough on on the bottom side of the motherboard there are two nodes that would press against the contacts.
Basically, the power button wasn't even connected to the board.
So I actually put the whole thing together, screws and all, and with that, the motherboard sits snugly as it should and the button works fine.
Right now my phone is some sort of hacked up zombie, with a cracked up screen, an upper-left corner that's completely decimated/missing, and no adhesive to hold it together. Hopefully the screen makes it here soon!
Oh and I agree totally, this is the smoothest and most reliable Android I've owned, better than the Evo 3D (which I quite liked) and a GS3 (meh, it got very unreliable after a year). I'm happy the screen replacement is cheap and easy so I can keep this thing for at least another year.
Cool glad it worked out for you or hopefully will. Can you do me a solid once your screen comes in and if it replaced well all working that is could you post the site you got it on or pm me with it. I am here tons of issues with defective screens. Would like to have a reliable market to shop from.

I have never had a bad part for any kind of phone from Wholesale Gadget Parts in Bixby, OK (Tulsa area). I found them on Amazon and originally ordered because they were close and I was in a hurry. I kept ordering because they get it right. I have about a 50/50 success rate with phone parts off other sellers on Amazon. If you buy cheap, expect a high failure rate.
Glass and digitizer for G Pro is about $18 before shipping and any applicable tax.
Yes, like it turned itself off but it did not go off as I was still getting audible email notifications. Tried everything speaking with Google support and then even Asus support who told me to go to their website and fill in an RMA form. This unit is 13 months old-out of warranty. There is nothing on the form relevant to the nexus to fill in so you cannot continue with it. So I am stuck right now and do not know what to do if anything. Any help would be appreciated.

Normally, 3 things can go wrong:
1. The cable is not connected properly. This could be caused by any impact. You take off the back cover and reseat it. It's the amber cable that runs the length of the battery. Be sure to check both ends. The one on the motherboard's end is in plain sight. The other end is hidden beneath the daughter board at the bottom of the tab, so you need to remove it to inspect the connection.
2. The backlight which illuminates the display went out. You can check this by turning the tab on and taking the tab to a dark room and shine a flashlight on the screen. If you can see the icons or the boot page, the back light is bad. The bad news is that you'd have to remove the lcd/touchscreen unit to replace the backlight. 10 times out of 10, when you do this on an original tab, you will break the touchscreen. Since it's glued to the lcd with LOCA (liquid optically clear adhesive), you will have to separate them, fix the backlight, buy a new touchscreen, then reassemble the whole thing. Most people would find it simpler to just buy a new lcd/touchscreen combo. If you're game though, I can give you an lcd back with a working backlight strip.
3. The video circuit on the motherboard went belly up. To test this, you need a micro usb to HDMI adapter like the one here , and a newer lcd TV. If nothing shows on your TV, the GPU is probably dead, in which case the only practical solution is to replace the motherboard since it's impossible to replace the GPU at home.
Good luck.

Did anyone else read this response and want to hit the edit button, and then type in huge letters "Time to buy a new Nexus!"
Thank you for your detailed reply. I checked the cable from the MB at both ends. Seems OK on the connections. I am unable to turn on the tab to check the backlight. That's about as far as I can go with it at this point. I am thinking that this tab is toast and to make matters worse, the abominably bad Asus customer service. I am considering replacing this with a Samsung and be done with it.

Hey, don't lose hope! Samsung is not any better specs or quality-wise (especially the display). If you're gonna butcher the thing anyway, might as well find out. I was gonna suggest to lend you a used lcd for you to test, but I realize people for some reason are extremely wary of gratuitous offers so I won't. But if you value it, try to get a screen with a good lcd but broken digitizer on Ebay. They wouldn't cost more than 15 bucks. Once you can determine it's not the motherboard, we can go from there. I can guide you on the replacement part if you want. I'm just a hobbyist, but I have messed around with this thing enough to tell.
Graph, you are kind to offer. I also have noticed that the glass has a few cracks in it as well. At this point, I can't turn it on. It seems like when I punch the on button in there is extremely little movement if at all. So I don't know if it is still on which I don't this it is or it shut itself off. When it was black screen and on, I was getting my email notifications audibly but since yesterday-none. I am not looking to spend big bucks on these things as essentially all I do mostly is use for reading. I do want to stick with android if I replace this. I know samsung does not have as good resolution but seems to get good reviews from users.
