I have a second generation Shield Tablet K1 that I purchased in December 2015.* The tablet was knocked off a counter and landed face down on travertine tile. The glass/digitizer did remarkably well considering but still had a large crack going down the middle of the screen. The tablet still worked in all regards* and I used it with no issues for 6 weeks. I purchased an NVIDIA SHIELD TABLET P1761W OEM LCD TOUCHSCREEN DIGITIZER on eBay.
I had the new digitizer installed locally at a phone/tablet repair shop. The shop called me and told me the tablet was ready for pickup but there were some issues with certain areas of touch screen not working. Basically the upper half of the touch screen works fine and the lower half does not work at all. As far as I can tell the area that works is exactly 50% of the screen. Just trying to do the basics on it right now is a pain as I have to rotate the tablet 180 degrees every few seconds in order to be able to touch a specific key or an app. Of course the shop won't warranty the work because I didn't buy the digitizer from them. What I'm wondering is if anyone can suggest a specific ribbon wire that may need to be replaced or simply checked to make sure the connection is good on it? Should I replace the touch screen controller?
Any suggestions will be much appreciated.
well, if you don't want to open it up yourself, maybe try getting another, more "able" person to look at it. Check reviews and the company, see if it's a known issue, it just might be a bad buy. I'm bet Ebay will do something about it if you contact them, also try contacting the supplier
I don't mind opening it up. I was hoping for some insight as to what to look for. I can swap out the Touchscreen Controller from my original digitizer and see if that corrects the issue. I thought with such a specific issue (only the upper half of the touchscreen working) someone could tell me yes, with that symptom you need to replace your Touchscreen Controller or that would only happen if XYZ ribbon weren't connected.
Maybe the touch screen is defect?
You're screwed. The repair shop tore the digitizer flex cable. The flex cable has no room to flex on an angle, so the cable just rips.
I just did this myself, and was looking around for a replacement when I found this thread. I couldn't find the problem until after I ripped it more; Now only the top left corner works.
I'm just buying a new one, because the problem I initially opened it to fix needs a heat gun, which I don't have.
Good luck

Ok so i walked into my desk at work last week and cracked the LCD - i had already puchased a new digitiser as my screen was getting pretty scratched up so i figured i'd simply buy a new LCD and take the phone and new parts round the corner to my local phone shop who were happy to replace my screen and return the next day.. great.
Fast foward and now i have a BIG problem. The new LCD doesnt seem to work once the phone has booted. SO, when you turn the phone on you get the usual windows boot screen with the rom info in red in the bottom corner (im using Monx's latese 6.5 rom). After that though it all goes Pete Tong, when then alignment wizard starts the screen goes nuts, flickering like an old TV and not displaying a steady image. The guys at the store say the phone is damaged from the knock to the screen however before I did a hard reset and removed my sim and SD card the parts of the LCD that were still able to display the today screen etc were showing everything correctly and flicker free and even allowed me full touch control with the stylus.
I basically need some advice from people who know a thing or two about replacing Touch Pro screens. Despite what the shop guys say i suspect that my screen is not compaitble with my Touch Pro which is originally a UK Vodafone but i now live in Canada and got the new LCD from the States. The person who sold me the LCD said it was compatible with all Touch Pros & Diamonds, but then he would say that wouldnt he!
My options are either buy another LCD and hope that does the trick or bite the bullet and get a new crappy canadian contract and a new handset. please help me ive tried the search and cant find anything that helps me and im desperate for a solution!
Cheers
Its a LCD issue what you got, my guess is that the person at the store either gave you a faulty one or its a duplicate lcd,also cleaning the LCD connector with alcohol would be a good idea.Its very rare that in the Diamond/Touch Pro category the connector to get damaged.
I just got an MZ604 from my friend. He said the display stopped working and eventually sent it off to Motorola. They sent it right back claiming water damage in the following areas: 121009-002454 (cannot find out what that means). My friend does not remember any liquid getting on the Xoom. The unit was useless to him so he gave it to me and bought an iPad.
I brought it home and had it down to the frame and cleaned all contacts with CRC cleaner. I did notice a carmel colored liquid near the lcd connector, not in it, but on the wafer board to the bottom left of the CPU. There was also a small black mark on the lcd connector on the mobo. Obviously that indicates a short, but I did get the screen to come on, but the digitizer was not working.
Now the screen does not come on at all, but the unit powers up. The unit charges just fine and shows up on my PC when I plug in the USB cable. I was actually able to sbf to JB just off of the prompts in RSD. After getting an hdmi cable, I found the output to work properly and oddly the digitizer worked too. By watching the display on my monitor, I was able to tap the keys on the tablet screen until I got the wifi turned on and entered my wifi code. I was able to update from 4.1.1 to 4.1.2. Both cameras work as well as the speakers and the sd card slot.
My question is this, does it sound like the mobo, or the lcd that is the problem and is the hdmi tied into the lcd output of the mobo somehow? I cannot find a replacement mobo to save my life and I would gladly fork over $60 for an lcd, but I would be taking a shot in the dark. If I cant fix it, I will sell it as a whole unit for parts. The case/screen are in perfect shape.
Any input would be awesome.
I'm in for the unit if you sell it, i don't think it's just your lcd but the mobo
That's what I'm hoping its not. I troubleshoot until I am out of options. I think that point is near. I'll put up some pics.

I have a a spare lcd, trust me you can drop it in your bathtub without risk. All that could happen is corroded contacts
What is the going rate for "for parts" Xoom?
I am uploading pics right now.
The plastic is still on the screen since being returned from Motorola.

Sheesh, good question. A new at Amazon sells for about 300$ on ebay bids for a new are around half that, direct buy for 200. All parts are separately for sale new except the digitizer. What do you find reasonable?
PM sent.
Got a couple of spare Shifts lying around that each had a separate problem.
On one the screen wouldnt come on at all, but the digitizer worked. Took it apart and noticed alot of wear on the ribbon. So the screen wont turn on but the digitizer and capacitive buttons register.
On the other the screen came on but the digitizer and capacitive buttons wouldnt respond unless the screen was slightly slid up at the top. So took apart and found the ribbon is actually split across and folded on one side. Funny how it actually worked until I put it back together. Now sliding it doesnt work either.
Tried swapping ribbons on each of the devices, issues remain. I did eventually get the split/folded ribbon to register a touch response ONCE since the swap, but not sure if it just wigged out on me for a minute.
So is there any kind of mix/match thing I can do to try and Frankenstein these phones to work?
FYI: both phones are RUU'd back to stock
To me it seems that both need new flex cables. I think you could just get new flex cables through Amazon. They're about $17 and ship directly from China.
I agree with Chad, it sounds like the Flex Cables are done. You may want to take his advice. But just be forewarned, make sure if you go with Ebay that the seller has good feedback. Also make sure to wear gloves whenever working on Devices, ground the work surface, and yourself. Static is not your friend .
oh dont worry, my shop is quite well equipped for anti-static and safety for both me and the devices i work on ^_^ i have been to ebay and found a worthwhile contributor for flex cables. thanks for the input guys. i still have NO IDEA how the split cable was even functioning. i feel as though if i had never decided to investigate the initial issue i would have been fine.
if anybody would like the two devices in their condition you may make me a small offer. not that im trying to really sell them off as i would like to have them as spares in case for whatever reason my working one decides to crap out and i have extra parts until i do get a flex cable. would be nice to have one on hand anyway. the cable in my current device is perfectly fine, but they do have a tendency to wear out especially since this one is quite used.
the one that originally had the split cable is in beautiful condition with hardly any scuffs or scratches on the digitizer. the other has a fine split on the right side of the digitizer, but it doesnt obscure its use. my current one is cricKet flashed with a similar split on the left of the digitizer. funnily enough it has 3g service but cant make calls or send texts outside of Pinger which is awesome because that means i still have contact outside of my home. it actually had working 4g until i obtained S-Off. now itll connect to 4g but wont actually send or receive any data.
Well keep us posted on how it goes. When you do decide to repair them.
So my photon Q is rather old. Shocking I'm sure. Recently the screen has started behaving very oddly. Flickers, sensitivity is weird, blacks out etc..
I thought perhaps flex ribbon due to keyboard sliding and closing but now I think may be digitizer or the lcd. I"m leaning towards digitizer becasue when it does work it looks perfectly clear. But there will be the one time i push the power to check if I have anything and nothing happens. Reset it and can see the screen wants to do something but can't decide what. Reset over and over and eventually boots up fine.
Digitizer?
Thanks for any info.
Anybody able to chime in
Flickering screen can't have anything to do with the digitizer. The digitizer is just there for input.
It could be that the connector is a bit loose on the mainboard. The way the Photon is designed I wouldn't think it's the ribbon. I could be, but very unlikely. Anyway it's worth looking into the connectors and just to be sure the ribbon as well. But that would take a full dismantle. The connector is just 5 minutes work.
Next time try booting into recovery. If that goes well (and regular boot not) i'm pretty sure it's a hardware problem (GPU).

When boot in any mode Ican't see anything.. A fading circle of grey lines runs vertically down the front. Sometimes after many reboots it fixes itself though. Good to know not digitizer. So take apart and check ribbon and maybe replace LCD likely?
I wonder if it is possible to simply replace the LCD if it's defective or if you have to replace the whole LCD-digitizer-speaker-etc set (which is expensive).

I ordered a replacement lcd screen so will find out. I also ordered the digitizer and flex cable.
So i'm thinking it may be more hardware involved than screen inolved. When it does work everything is usable and it works fine. This is only about 10% of the time at this point. Otherwise it boots up to show some vertical lines traveling down the middle of the screen but only in a circle in the middle of the screen that fades as it gets close to the edges. I'll try taking apart tomorrow night to see if ribbon and what not looks ok. But so far i've invested about $70 into parts and i'm thinkin about just snagging an S5 for $100. I will miss the keyboard though although I can hope that like the s3 and s4, the s5 will get a keyboard attachment. Thoughts?
If I remember correctly the LCD comes with the ribbon and camera connected. The digitizer is connected via a ribbon to a board in the top of the front panel. You could try to disable the pin. When the phone doesn't seem to work, reboot and try calling yourself. If it rings, there's something wrong with the screen and not the phone.
If there was something seriously wrong with the phone, it wouldn't boot. But that's just me guessing/assuming.
My daughter's Photon has had a digitzer replacement twice. And it looks like it's been used to play football. But that one still rocks. No quirks or any strange behavior for that matter.
What I'm trying to say is that the Photon is a decent piece of hardware. A family of four, we all have a Photon. Three of which have had their digitizer replaced and one an LCD (scratched it when replacing digitizer).
I swapped my Razr HD for an Z2. It was time for a new corporate phone. So that, and the camera, is the reason why I went for a Z2. My options were 930/G3/S5/Z2. S5 is not my cup of tea. The G3 has no ruggedness whatsoever. The 930, apart from WP maybe I should have went for it.
So it came down to the Z2. To be honest I'm looking to trade it when the Z3 compact arrives. We'll see.
@Loader009
Digitizer is a part, board for speaker is a part, the speaker itself is a part (adhesive, watch out, btw 100% the same as Droid4), and the LCD is a part on it's own.
Going to open up my phone tonight after work. I was bored and was just playing with the keyboard sliding it open and closed a bunch and now the screen looks perfectly clear.. although sometimes it will still black out and I have to reboot it a few times to get it back. I feel its more a connection inside like you stated earlier. I love my Photon and really don't want to have to get a non slider phone. New phone's are so friggin huge lol.
The good thing is, the PQ has gotten pretty cheap, so you might want to get a used one at ebay if the part to replace is too expensive.
flickering screen (backlight) is not lcd problem.
for 70% is it problem on mainboard - backlight ic. This problem is caused by using unoriginal charger.
and 30% flex problem
I had my screen become un-responsive etc, it was due to a crack in the ribbon. Swapped it out & all ok.
Easier to swap the whole screen assy than to change the ribbon, but depends on what spares you have/can get.
You'd need to have a good look at the ribbon for any damage.

My sister just broke her moto x pure.
The display works, however the digitizer do not works correctly. Cannot post pictures because the wallpaper is containing private information and i cannot change it.
She cannot use the entire screen.
For example on the lockscreen, she cannot use the 8. And the other digits works very badly. So she cannot unlock her phone.
What should I replace (screen, digitizer...) and where should I find the replacement part ?
Thank for your help
You'll need to replace both the digitizer + display as they come together. If you are good at repairing phones, you can get the display from eBay or else send your phone to service center if you don't. I would suggest you to send it to the service center.
You could use a USB OTG cable to connect a mouse and thus regain control of the device in order to clear any sensitive information prior to having someone fix it. I have bought and fixed several Moto X pure edition phones with cracked screens for family members. Most of them did alright, but one phone had the screen replaced, then a cow stepped on it. Although it didn't crack, after a while parts of the screen stopped responding to touch. The screen I replaced it with has not been damaged at all, but parts of it have stopped responding to touch as well. Sometimes I wonder if these phones don't have a particularly weak and easily damaged screen. I sometimes get my replacement screens from GadgetFix. If you fix it yourself make absolutely sure that you get a screen+frame assembly. It's just a few dollars more, and totally worth it. And be careful when you transfer the speaker grill trim to the new screen that you don't press hard enough to crack the screen.
Thanks you, I think I will change the screen and the frame.

Is this what I should buy ?
The screen that you posted does not include the frame. I briefly looked on eBay; you might find one with the frame included for a few dollars less than gadget fix, but for simplicity I just linked this one. On the back side of the display you will notice the screw inserts. That is what you need to look for.

Thanks !
Could you point me to a tutorial or a video explaining how to change the screen
I believe that Ifixit has a whole teardown tutorial for this phone. If not just search YouTube for (phone model) screen replacement, watch it a time or two, and then pause it while you do each individual step. If the first video you watch doesn't explain things in an understandable manner just watch another one. It's been a while since I searched for one, but I think there are at least a few good ones.
