Problems with Alpine touchscreen

Recently I added a screen protector to my Alpine, and after that the screen started acting funny any time it was left alone. Removing the screen protector has made no difference.
After a short while of not being used, the screen becomes misaligned, for example if I leave it off for an hour, attempting to activate the start menu on the today screen will result in one of the today items being pushed, or attempting to select a number on the password entry will result in a different number being pressed.
The strange thing is I can re-align the screen through the control panel, but it will slowly go back to the way it was.
Anyone got any thoughts? At worst, I'll just refund it (I bought it where I work, and thats no problem) and get another handset, but if theres a fix I'd prefer to stick with my current handset.
Cheers in advance for any help!

I am not sure about this, but I had the same problem with Motorola A1000 touch screen - could it be that an excessive pressure was applied to one of the sides of the digitizer during the application of screen protector? The digitizer is glued on the LCD, there might be a remote chance that it has slid a little to one side. Also some extra glue could have shortened the contacts on the bottom part of the digitizer. I would try to clean it first with some anti-static liquid. Hope this helps..

Indeed, this sounds like there could be more pressure to one side of the screen than the other, hence the digitiser tries to adjust for the pressure difference and gradually falls out of sync.
Try reapplying your screen protector, more gently than last time if possible, but don't wipe from side to side, wipe from top to bottom with an even pressure. Also, try realigning the screen with the protector off before reapplying it.
I had a problem with my screen originally before I got my screen protector, insofar as I got that 'rainbow' pooling effect in the centre of the screen where the digitiser was touching the LCD layer - after about a week after application of the screen protector, however, the more even layer of tension provided by the protector somehow pulled the digitiser away from the LCD layer, so my screen has actually gotten better since then... That said, I could imagine that uneven tension on the top layer could lift the LCD and digitiser layers further away from each other on one side than on the other, causing the problem you describe here. If you can bear to, try using the phone for a couple of days without the protective top layer applied, and see if the alignment gradually slips out as it's doing at the moment.

I've been using the phone for the past two days without the protective cover on. I'm going to reapply it now and then see how it goes tomorrow. If its still screwed, I'll reflash it to the O2 ROM and refund it at work on Tuesday.

Got a replacement, so no problem now. Thanks for the help anyhow

**~htc touch screen not working!!!!~**

hi,
my touch diamond 2's touch screen stop working randomly ( i think that i applied too much pressure on 1 spot for too long). I can see the touch screen dots on the area. I am just wondering if I were to repair this, would i be replacing the DIGITIZER or the TOUCH SCREEN.
Thank you soo much

warranty might cover that. It might not be your fault

I have decided to fix the part myself since I do not wish to ship the part to their location in the US. Any idea if its the digitizer or the LCD screen that i should be replacing?

Search the Wiki, there are dismantle instructions.

I had the same on my display, and was able to move the dark spot to the edges where it disappeared.
I moved it with scratching it with my nail very gently applying some pressure.
In Europe HTC offers a pickup and return warranty, is that different in the US? If it is the same I would send it in to HTC for replacement, since it might happen again pretty soon....
I already have 3 screens replaced :-(

jason, did u manage to fix this? i have the exact same problem and pushing the "bubbles" towards the edge of the screen didn't help. my screen is still unresponsive..

Try applying duct tape to it repeatedly until you get it back.

Yes, both
I recently replaced the Touch Screen on my Diamond 2. Same problem; spots that "stick" in the middle. I used to solve this by running both my thumbs down the sides of the screen to "puff up" the low areas in the middle.
The part you want is actually called a "Digitizer Touch Screen" on eBay, cheap too. Prepare to spend about 2 hours fiddling with very tiny screws, connections and glue to tackle the job.
The hardest part for me was actually getting the Touch Screen to work; it seemed to be calibrated in mirror-image AND turned 90 degrees sideways, which made getting to the calibration functionality an extremely frustrating experience. I spend another 3 hours on that, but now I've got a perfect phone again, since I ordered a new case as well. No use taking the entire phone apart and then rebuilding with a molested outer shell...

maybe you should reset it

Working Solution Till Now
Hello Friends,
I have TD2 mobile and today I had same issue. I was thinking it was because of the weather or some.
I remember it did happend several time before, but when I restart the device several time it does work. So I was ignoring.... But today it did not work.. looks like going toward end... So I did soft and hard reset without and that did not helped me.
So I switched off the mobile, "heated" the touch screen gently with my hand for 1 min and started the mobile again and it worked for me .
Not sure if this is a solution, but will work.
May be I will contact Service Center here in Hyderbad and see what is wrong here?
Hope this will help you all...
Thanks.

Solution
Okay, I've just had this problem with an HTC Touch, and I think this works with any HTC that has a "digitizer" rather than an all-in-one touchscreen (I think newer phones have digitisers).
I'm not sure if this will always work, but I've just done it - sometimes the inactive touch screen is "broken" because the layers are stuck together (so the phone can't tell where the touch is, hence unresponsive). With mine, I looked at the screen side on and could see a kind of "oily" patch in the light.
The solution is to get masking/gaffa tape - the very sticky brown one. Stick it down on the screen/digitizer and then keep pulling it off - this pulls the layers from each other. I kept repeating this lots before it worked - and in the end I pulled the top layer completely off (I think you should pull from the top of the phone, as the layers need to be attached at the bottom of the screen/digitizer). Once it pulled away, I gently lay it back down (after panicking!!) and hey presto it started working again.
Good luck!

Digitizer replaced but still not working
The touch screen on my Touch Diamond2 stopped responding to my touch (or the stylus) and I tried everything including removing and replacing the digitizer bus just in case the connection was the issue. But all to no avail. Finally I decided to replace the digitizer (touch screen)
The problem for me is that it made no difference. The new digitizer doesn't respond to my touch either. The problem is apparently somewhere else.
If anyone has encountered this problem and has a solution I would be grateful to know what it is.
Thanks in advance

Replace the Touch Diamond2 Digitizer touch screen.
I recently replaced the digitizer (touch screen) on my HTC Touch Diamond2. Since I found on the net, no instructions for replacing the actual digitizer, I thought I might include some here.
It was relatively easy to fit. The only difficulty I encountered was a lack of information about how to actually remove the old one. The various instruction sets found on the web all stop once the screen is removed. But the digitizer is not covered by these instructions. The digitizer is bonded to a thin glass immediately under your screen protector (if you have one fitted) and after the screen is removed following instructions you will find on the net, the digitizer and the thin glass sheet that it is bonded to must be prized off from the front of the housing. The digitizer separates from the glass easily, but the glass is securely bonded to the housing with a silicon glue. It must be prized off by gently lifting a corner and applying a little upward pressure allowing the glue to slowly and gently let go. Don't be surprised if the glass breaks during the process. Once off it is a simple matter to press the new one in place. Just remember to start by slipping the connector bus (cable) through the narrow slot between the metal outer housing and the inner components. I used a set of tweezers to poke it through. DO IT FIRST before pressing the digitizer into place.
Okay, as I said the process was easy and took about 15 minutes all up.

Thanks for the heads up on the glass part mate. Just replaced my TD2 digitizer too. Kinda freaked out at first when the glass split.. haha
Anyway, just wanna 1 more info. When removing the old digitizer, it'll be easier if the front housing was heated first (with a hairdryer on full or a heatgun) to soften the glue. It'll be easier to remove afterwards.
Word of warning though. Only head the housing when REMOVING the old digitizer, DO NOT use this method when applying the new one. The digitizer dies because of heat. Heat is what causes the newton rings issue.

Shoofty, did you manage to fix yours?

Fixing TD2 touch screen
TD2 touch screen is a common problem I guess.
Symptoms are :
1- Touch screen does not respond sometimes
2- You can see a grease like layer under the touch screen
3- Sometimes if you look closer to the screen at some part you can see a a liquidized small area.
Solutions:
1- If you see the liquidized dot on the screen turn off the display and try to rub it with your finger until it disappears. turn it on again and try if it works. I guess heating with the finger as other peeople here suggest does the same thing. However this is a temporary solution. Your touchscreen will die at some date. I used my TD2 for 8-9 months using this method. But at the end touchscreen died.
2- Replace the digitzer or complete frontcover. Actually this might be easier than you think. I replaced mine in half an hour. I bought a front cover which includes the digitzer (http://www.ebay.de/itm/Original-HTC...zer_Ersatzteile_Werkzeuge&hash=item4cfe6f78dc) and openning tools from ebay. Dimanıond 2 disassemble and assemble videos on youtube were very helpful. I strongly suggest to buy the complete frontcover (inc digitzer). It makes replace process much easier and gives the device a brand new look. My old front cover was worn from the corners (which is also very commpn problem of TD2). Now it looks brand new. No strach on the display and body.

Thnks Ozkarah.
I happened to realize that, surprisingly, the touch screen of my HD2 started working if I heated it up with a hairdryer. So, I think something else is wrong beyond the touch screen, probably the connector to the main board of the mobile. It might expand once it is hot and that is why it starts working. In any case, I think that is beyond repair

Hi,
I have same problem when I changed new screen (screen is calibrated in mirror-image AND turned 90 degrees sideways).
Could tell step by step how you get your screen calibrated?
Thanks

[Q] screen protector question

I have experimented with various screen protectors on the Moto X. The one that I have on now covers the left side portion by the ear speaker. I have also seen screen protectors that purposely have this area cut out of the screen protector. I believe that this is where the light sensor is. I have been trying this screen protector out for a couple days (it is a anti-glare kind and is opaque) I have noticed that the active notifications don't come on as much...however, this may all be in my head. Curious if anyone else had tested this. See attached picture.

The screen protector I used ( Xtreme guard) has an extra area cut out to the left of the speaker, i guess for the proximity/light sensors..
and I don't have any issues with active notifications.. maybe you can cut it out?

That is the proximity / light sensor. Play with it when you're in a call - cover it up with your finger, and the screen goes off, remove your finger, and the screen comes back on. That's how your phone knows it's up to your face and to turn the screen off so you don't accidentally face dial. Some screen protectors don't affect it, others seem to. I don't doubt that your active notifications are funny if that piece is covered up. I had a tempered glass protector on that covered it. I had some issues with the screen not coming on when I took my phone away from the face to end the call. Sometimes active display would randomly turn on when the phone was sitting still on my desk. After I switched to a different brand that didn't cover it up, my problems went away.

Thank you for the info. I had a feeling that there was something up because it was acting a little random after putting that protector on. I don't think all companies really test their accessories on the phones they make them for...other than that they fit okay but not if they affect performance. Those test would take too much time. Funny thing is I got them from a Sprint store and they were $20 for two :/ . I found some, actually the exact one's Moto's sight selling, on Amazon for around six dollars something and they have a space cut out for that area.

Huawei p9 black screen

Sorry if this is the wrong place to post or it's been covered already. I have a p9 stock that I changed the screen on after dropping it. Everything was fine until the new screen started to fail, it was a cheap eBay screen and the glass started peeling away. I fitted a new one and when I switched it on the backlight comes on but no image, backlight then flashes 5 times and then stays on. The phone does the one vibration like it's starting up but after that does nothing. I tried the reset procedures but doesn't help. It wasn't on USB debug so I can't connect with my pc. I first thought the screen was faulty so had the vendor replace it but still have the same problem. Could it be the main board has been damaged or the flex cable?

Sounds like a batch of bad screens. I would stay away from eBay when it comes to Huawei P9 screens, too many issues with them. Had ones that were refurbished or glass separating from the screen frame.
Buying it without the frame and applying the adhesive yourself seems to work better for me. Anyway hopefully you didn't kill the backlight circuit on your phone.

Backlight seems to be fine. You could be right, there's a faint blue tinge in one area.

Hey, did you ever solve this? I have the very same problem

Screen won't show after cracking the screen

So my phone cracked up today(rip) while I was doing some gym exercises. The phone fell from like 1.5 metter or so and the screen cracked.
The problem is that screen won't turn on, even when the phone looks like it works. I tried to furce shut down and turn it on and back and recents buttons work, but screen while stay black. What should I do? I will replace the screen but I'm not sure why screen won't show up, maybe something got disconected with the fell? Does anyone has any type of experience with this?

So, your screen is broken, and you need to have it repaired, what is the problem? Some parts still working?
Just get it fixed...

I really don't know why you asked this question, but I always try to be helpful. Since you did drop it, and from such a height (do you like keep your phone in your pocket while doing pull-ups? Mine's always in my bag and I use BT earphones).
Since your screen is cracked, and that impact could've damaged your phone in many ways.
1. You could've damaged your digitizer, which is a screen replacement situation
2. You bent a cable from your screen to something else, and that may be the issue, still would need to replace the screen.
Your buttons working have no relativity with the screen not working, it works with other hardware not interacting with your screen.
Don't go for third-party screen replacements that "fixes your digitizer seperate from the touch", it mostly doesn't work, and it'll be a waste of money, if you bought it from OP Store, just RMA it, or if you bought it from a seller in your country, just order the screen off eBay, and have it fixed. Your shop will most likely replace it with a non original screen, which will be horrible.
Cheers!

I think he is confused about the glass versus the AMOLED panel. A lot of times, you see folks with broken glass, but the screen still works (still displays graphics) and he is wondering why that isn't the case. At least, that is how I'm interpreting the question.
The answer is that the "screen" is composed of layers. The top layer is the glass (which for Super AMOLED also incorporates the touch panel or digitizer) and below that is the AMOLED which actually displays the graphics.
Since the glass is broken, and the AMOLED is not working, it's possible (or even likely) that the AMOLED was also broken in the impact. Yes, it's also possible that a connector has come loose. But from what I'm reading, it's actually common for the AMOLED to break before Gorilla Glass does: http://www.gophermods.com/amoled-vs-lcd-tale-two-screens/
A lot of times when you see folks with glass broken, but everything (touch and graphics) still work, it may be with LCD screens; which are supposedly more durable (more possible for glass to break before the LCD).
