How to Figure out if touchscreen or LCD or both are broken?

Hello Friends,
yesterday when i saw the screen of my xda exec i saw a big black spot on the centre of the screen, not sure how it happened. i can still make calls from the phone.
but now i want to figure out whether i'll need to replace touchscreen or the LCD or both but i dont know how to figure out which one is broken.
Any help will be really appreciated on this.

Chances are
if the touch capability is intact, it's your LCD. The opposite, where the screen looks fine, but the touch is gone, would be your digitizer. However, unless you know how to replace a digitizer, I recommend getting both, LCD and a digitizer in one unit, rather than attempt to assemble the screen yourself. Which, judging by your question, is likely to be the case.

I would only iterate what enigma1nz had to say . It's at least your LCD at fault, but buy both as one unit. Or, buy a Uni that guarantees a working LCD+Touch pad (ie, a Uni with only a broken broken mobo/usb/doesn't boot etc) from eBay or the like.
First of all, I would just take the screen part of the Uni apart and check all is tight when replacing, as if the LCD has no obvious cracks, it's very likely a rubber-strip contact or similar.
NB. If anyone is interested in purchasing a fully-working Uni (brand new casing), with a non-functional touch/digitizer (guaranteed working everything else incl. LCD), I'm about to put on eBay. (PM me)

I fear my Uni won't rotate anymore soon

I'm using my HTC Universal since 2 years ago and it was already secondhand.
Does anyone know how to repair or reset the status of the part that makes it rotate? (sorry if I'm not understandable )
Thank you in advance,
Regards.

Sorry, you were not clear enough. What are you trying to achieve?
Do you mean the hinge part is broken and the LCD cannot be rotated? In which case hinge will need to be replaced, but they are difficult to find, sometimes they sell on eBay or you can purchase parts off someone selling his broken machine for parts, then use a Service Manual for disassembly instructions.
If you mean the screen orientation does not change when you rotate the screen, then you need to open the LCD side and check for a small magnet next to a screen, as it is the part responsible for rotation. However, sometimes the problem like that can be caused by software, so you need to be sure which one it is.

Thanks for your exhaustive reply! Yes, it's an hardware problem. I want not to be in condition of not rotating the display, so I'm looking for a solution for the hinge. Something I can do on my own.

What is exactly wrong with your hinge? How is it broken? Pictures would be helpful.

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, the same for me.
Touch doesn't work on some area.
Need change digitizer or LCD?

Antenna gps
Hi someone tell me where it's possible to buy a part "gps antenna "?

LCD Screens from HTC Touch HD and HTC Blackstone are working correct. Use these replacements instead of original

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

Broken touchscreen :eek:

Hello dear community, my dreadiest fear just realized today :
my X2 decided to make one with the concrete...
luckily, both with my heart, only the touchscreen shattered from this unholy union.
So now I want to replace only the broken thing (less expensive) with a replacement part I found on aliexpress (25 € for those wandering), BUT I was unable to find any clue about the separation of the LCD and the touchscreen :
Are they inextricably bound together as the galaxy S series are ?
Or are they just attached with some tape as any good reparable phone should be ?
I was also wandering whether the screen parts were the same between the X1 and the X2 !
If you have any material showing how to proceed with the separation, and care to share them, I'd be in your dept forever !!
Boujou bien !

The disassembly should be the same as the X1 video here:
https://www.youtube.com/watch?v=8NOG1SISbKw

Yes I have seen this video, but it is only showing the removing of the screen/touchscreen from the phone, not the separation of the LCD from the touchscreen (they are both broken in the video, hence no point to mess with them !)

They are fused together so it's not even worth trying to remove them. 99.99% of the time you won't be successful.

Good to know !
I almost succeeded once, with a heated bench, But I'm not willing to try that again…
Did you have to fix yours already ? Any clue about backward compatibility with the X1 assembly (20 % cheaper !) ?

I imagine they would be the same display assembly but I'm not 100 percent sure.

I Sat on my Huawei honor X2 -Screen is not working Properly
Hello (posted this in wrong area a few weeks ago)
I sat on my X2 GEM-703L under several pillows - bend was 1/2 inch - the top & bottom were 1/2 inch lower than center . I carefully bent it straight (there is a small kink in metal frame right side just above center button. Everything else seems to work beside the screen. *** I will push "4" and the key adjacent character is recognized, also it will type on its own or type 3-5 characters when I only pushed one...
Questions:. Does this sound like touch screen Replacement will fix these issues??? Or is thier additional interface hardware attached with the touch screen, or both?
- I really like that phone - hoping it is not a lost cause...
Thanks for your help

Hello Gary, sorry just saw your post.
I Think this might be fixed by a change of screen, but the problem might also come from the bent frame too.
For the tactile to work properly, and not register wrong input, the screen needs to be grounded and I think also calibrated to the phone caracteristics. If you just replace the screen, it's environment would not be the same as it is suppose to be anymore (frame with a kink) hence there is a risk that the new screen might reacts weirdly, registering ghost input etc... Because the screen might not rest flat on the support frame, and the contacts used for grounding might not be working anymore.
I have a spare screen that I*just bought for mine, unfortunately my problem seems to come from the motherboard, so the screen is useless for me.
If you want to give it a try, and live in the US, pm me !
If you don't want to do it (the screen comes without a frame, so you have to use your old one)
I'm willing to buy your phone to try to save mine ! :angel:
Best,
Quentin.

Strange problem with touchscreen

Hello, guys.
Recently, I dropped my M2 on the street, resulting in cracked touchscreen and lcd. Replaced both the touch and the lcd, everything seemed normal until I noticed that the middle part of the touch (a line going from the left to the right, around 1cm height) doesn't work, it just doesn't respond. Later, I got another new touchscreen and same story - same part of the screen doesn't work.
Maybe we have some kind of defect touch screens here in Bulgarian stores? Though I bought the two touches from two seperate stores. Or it's possible that it's something with the lcd? Even though it works normally, no strange behavior, no black spots, scratches or anything. Or could it be a software problem? Using Android 5.0.
Thanks in advance.

More likely to be motherboard problem if it's the same with 2 different screens being installed

Thanks for your answer.
One thing I forgot to mention - when testing the screen in Sony's Sketch app or in the service menu, if I run my finger from the top to the bottom, or the opposite way quickly, sometimes, the lines my finger makes don't get cut, i.e. it's like the screen is functioning properly, with no dead spots. What does this mean?

According to Sony support, it could be a compatibility issue between the phone/touchscreen/LCD, what do you think?
