[Q] Is this an LCD screen problem or Phone internals problem? - Motorola Atrix 2

I am fixing my broken Atrix 2's screen. The touchscreen digitizer and LCD were both cracked. I purchased OEM replacments and the touchscreen works great but I am having display problems with the LCD.
The LCD I received doesn't seem to have the same pixel density or color gamut. It also flickers a lot and then goes dead after having to change what is on the display, ie watching a video or switching screens fast.
When I hook up the HDMI cable, the output to my tv doesn't have the same problem as you can see from the video in the link. I have some other videos that I can upload if needed.
The vendor is going to exchange the LCD screen for me but my question is could this be a problem with the phone itself and not a bad LCD screen, being that my damage came from falling off and then being run over by a car? I don't want them to have to send out another LCD if my Atrix 2 just won't work any longer.
When I had the phone apart there was not any visible physical damage to the board or other internals.
Thoughts, suggestions?
Apologizing up front for the Portrait video.

Here is another video. Again sorry for portrait but I wanted to get the whole screen on the screen.

Its a screen problem, LCD cable/connector problem to be specific... if it was a GPU problem, the HDMI wouldnt function either.

Thank you very much, I will look into this one.
screen seems to work fine, installation was not too hard. However, new screen acts little weird, as once phone is off, backlight turns off immediately, but you still can see image for few seconds under normal light, pixels show through, and then it fades away.
Look for an original AUO H380VL01 or HTC Touch HD Sharp matrix... It's reported to be compatible with our phone
cracked screen too

I installed mine today -after 6 months with broken screen- I bought lcd for HTC Touch HD T8282.It is far more cheaper than the acer one and fits perfectly.ebay item 290424248491.
The HD screen is the same of NeoTouch?
I've paid 70€ for a screen for newTouch, but your proposition is more good: 50€!!
Are you sure it's good for Acer? My touchscreen is OK...
Im using it since last friday. its perfect
I received my screen today, but it's difficult to open this mobile phone!
I remove 5 screw on sur back of the phone, but i don't know what remove
There are two more screws at the left and right sides of battery house

i have the same prob.... i dropped my phone and my screen blanked ....and i need another lcd .... i was thinking about what you did.... but if i'll get the HTC one the front of the mobile will be with HTC logo instead of the ACER one ...
right?
screen now fixed
I took my phone in to a local shop and they were able to change out the screen using an HTC HD screen (yes, the exact same screen as the neotouch). All is fine with the screen. They messed up the power button, but that is another story. I watched the guy do this and it seemed like a hell of a lot of intricate work to do yourself. I was happy to pay the $120. Now, I just need to return and get them to redo the power button (installed it incorrectly when putting it all back together).
For those adventurous enough- go for it, but I suggest the cheaper HD screen. And no, only the screen was replaced, which is under the touch screen/digitizer that actually has the acer logo. All looks as it did before.
I took my neotouch for a motocycleride in the rain. It didn't like it too much and now the touchfunction is messed up on parts of the screen. It all displays as it should but I can't use parts of the screen. I should be allright with just replacing the digitizer right? Ebay item Item number: 170518652337

Hi,
this didn't work in my case. After replacing my broken original lcd screen with a new lcd display (eBay - No. 120608475783, Original HTC Touch HD LCD Display T8282), I can see that the display is switched on, but it doesn't seem to receive any signal (like you turn on your pc monitor but not the pc). Now I have two questions:
1.) If only the lcd display is broken - should I still see something on the display? Because on my broken display, I only have a black and a white part and some coloured stripes, mostly where the display is broken.
2.) Is it possible that there is something more broken on my NeoTouch or did I simply receive a broken lcd panel? It did fall off the couch, completely flat on the display.
fyi: the new lcd was missing some isolation (on the flexible part with some electrical components) which was present on my original lcd. I used some sticky tape as a replacement because it is directly positioned over some other electrical components on the phone when in place.
New Info:
Everything except from the display seems to be fine - when it is connected to my PC running "My Mobiler". But I have seen pictures of mobiles with a cracked screen whre you were still able to see (partly) the homescreen, etc. On mine, I am not able to see anything while the cracked screen is mounted - only white and black parts and some colored stripes...
Update: The delivered display was broken. Yesterday I received a new one which works perfectly!
many thanks in advance

aih, the same story with my f1
anyway could you suggested seller lcd f1 on ebay???
i'm afraid if wrong order with lcd resolution under wvga,,,
some seller show resolution from their prodocut and a lot of seller don't do that,,
please help me..

[Q] Damaged display

On my almost 3 years old I had "oily stain" - obviously from wearing in pocket of my jeans. Pressure on display causes this problem. I dismantled phone and by aplying pressure on corners get rid of stain(done this once, it help for some time). But after powering up the phone, display was dark and with some strange colors(purple, pink...). I think I fu*ked up some of the flex cables with display signal or display itself, display doesnt look cracked and I am convinced that its not issue of backlight. Question is: Did someone saw this problem? Do you think that buying a new display from eBay(~$20) worth it? I am going to buy HD2(Leo) soon.. I tried to take photo but my camera cannot take that dark picture...
it seems display is damaged i took of whole display unit. Gonna buy new LCD sell it on ebay and buy HD2
Have the same problem on my touch pro after changing the screen. Dark display with some colored stripes that changes after i press some buttons or play a little with the touchscreen. I've tried to reconnect everything, play a little with the flex cables applying coductive tape etc. but no change. The LCD seems fine.
I have created threads regarding my problem at differrent forums but noone seem to know the cause or a solution.
Your problems are probably caused by a defective of flex.

digitizer or LCD screen.

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.

[Q] Dropped my OPO, now a section of the touchscreen is unresponsive

Since I have had the OPO I have had intermittent issues with the touchscreen requiring reboot to solve. Since upgrading to CM12 the issues seem to have largely subsided but last night I dropped the handset from about 18 inches off the ground. The top left corner of the screen shows a bit of cracking on the glass and now I notice that there is an area in about 1/3 of the touchscreen that is unresponsive. The lower and upper parts of the screen work but now there are some apps and functions I cannot use with the touchscreen and I notice I have having a lot of trouble with the pattern unlock screen as well.
My question is whether the entire digitizer screen will need to be replaced or if there is a possibility that the ribbon connectors or some other connection is possibly causing this issue. I have attached here a pic of the physical damage and a screencast of multitouch test that I ran to demonstrate the area affected. It seems to start around y0=400 and continue to y0=1100 or so which is quite frustrating. In the video I am just running my finger up and down the screen and also across diagonally to demonstrate the problem areas.
Apparently I cannot post Youtube links since I am a new member but the video is on there posted under
"OPO touch screen issues after drop"
Anyone with insight would be much appreciated as I certainly would not like to have to tear this phone down and replace the screen assembly.
I doubt it's a ribbon cable, otherwise your whole screen would be dodgy. I think you need a new digitizer + LCD.
Here's a link for the video you are trying to link to.

[Q] Oneplus One screen replacement

Hi all,
after a drop the glass of my 16GB OPO crashed. The touchscreen doesn't work anymore, if I touch at any point of the screen nothing happens. Btw, the LCD display still works as you can see from the pic.
So:
Broken glass;
broken touchscreen;
Working LCD panel.
What's the best and/or cheaper place to buy a quality glass+touchscreen?
Thanks in advance.
