Touchscreen not working - MDA III, XDA III, PDA2k, 9090 General

Hello, I am having serious issues with the touchscreen of my BA.
The screen part is kind os loose, it moves slightly sideways.
I have no idea if the two things are connected, the touchscreen also does not work properly, as it randomly does not detect taps.
I have noticed that if I press for a bit the sides of the screen down onto the back of the BA, it works better for a while.
Do you guys have any clue on what the issue could be and how to solve it?
I myself have the idea that some tap detecting thing behind the screen has detached from the screen itself, and that I have to open it to fix it. Am I wrong?

Up.
Anybody who can give some advise before I take it to assistence?

unfortunatly
i have the same issue...and everybody is telling me i need new screen ..if u get a solution... i'd be grateful if u tell me.thnx alot

Hi, I have disassembled it, trying to understand something, but really nothing happened, I can't pretend much since i am not an expert. i have no clue, that is why i am about to take it to the shop and get it fixed. damn it.

hi..
saw this in another site..hope it helps..
"Are you using a screen protector that has got under the case or could there be a bit of detritus between the screen and the case? These cause pressure on the digitizer making it unable to register taps.
Take off the screen protector and see if any improvement. Fold a piece from a sheet of copier paper at the corner to make a scoop and go around the edge of your digitizer just under the case."

tapping problems - touch screen is not working

Using my htc device suddenly touch screen went off and i could'nt use the stylus at all. The strange thing is that all of the other keys are working good. I tried hard reset the device but nothing happened. Now im stuck in the screen "tap the sreen to set up your windows mobile based device. Can anyone please help? Before the appearence of the above problem i was using google maps, if this helps.
many thanks
Does t have a crack in it? If so then it needs changing, if not then probably the ribbon has come out. Is it under warranty?
no there is nt any crack! everything was good and suddenly while i was tapping to check some maps, stopped.
Sorry for asking but ribbon is that thing above the screen? Is it possible to come out so soon? (6 months). and finally does the warranty covers ribbon change?
Sorry for the above questions but i really dont know what to do!
many thanks
call the company where you buy it from and ask them

If it's only 6 mths old it shoud be under warranty, so take it back to the place you ought it.
If you are determined to try to fix it yourself you have to do the following.
Remove the battery cover & battery.
Remove the 4 small screws
Remove the back-case by running your fingernail round the gap (hard 1st time then easy after that)
Remove 4 more screws
Remove front-case from the middle
Remove the motherboard assembly from the front case and unplug the screen/digitiser assembly, carefully pull that off the motherboard (again not easy 1st time).
You will now see the small digitiser ribbon at the bottom coming off the digitiser and disappearing into the bottom of the screen. It's very easy to take out and not easy to put back in. I use some flat-bladed tweezers to do mine but sometimes it takes a couple of tries. Obviously it's much easier if you are fitting a new digitiser because it's not fixed to the screen like yours will be. If you try to remove the digitiser chances are you will crack it. I re-fitted mine after removing my broken one by using thin cut strips of double-sided tape.
Before you do anything else, just clean with sharp knive or razor between the screen and the cover.You will be surprised how much rubish is is in there.
this things are keeping the screen pressed.
Hope it helps
many thanx 4 the instrustions guys. i'll try that. if everything ok i'll inform you. if not i'll give you my bank account number to deposit money in order to buy a new one.
many thanx again

take apart lg ks20

i need to take apart my ks20. want to repaint the chrome like frame that goes around the phone (lg used some cheap paint, it comes off really easy). I have looked at the service manual, but couldn't get anywhere. After taking out the battery and sim card, there are to screws on top that i removed, i tried to remove the back plastic cover (the one with the camera opening) and no luck, it doesn't budge.
does someone know how to do this? i think the service manual is somewhere on the site, but i have no idea how to proceed.
thanx a lot
Try

thanx for the link, but i have looked at the manual and can't make up anything of it
it doesn't say how to go about taking it apart, all it shows is a diagram with all the pieces
is there anyone here who knows or at least has an idea about this, i really need to get it repainted (i hate scratched phones)
thanx a lot
Maybe some one can answer this question? I also need to disassemble my KS20 - because of dirt on camera lens...
The disassembly is fairly straightforward - remove the battery, remove the visible screws, run a special tool along the black plastic and unclip. It's not easy, but it will come off. The back cover houses thermal pad, because KS20 gets quite hot from time to time. I guess LG didn't anticipate that happening, so the pad is a bit of a last resort solution from them, quite unorthodox.
As far as middle silver strip is concerned, it houses a flex, so unless you know what you are doing - don't bother touching beyond the back cover.
hi, i dissambled my ks20 today.. and i think there's a problem...
my screen wont turn on anymore...there are still sounds and even the touch screen is working..its just that my screen is not showing anything...
i think the connection between the screen and the motherboard was loose...
but then again, i cannot find the connector... can someone help me with this...
Hi,
Read this KS20
By.
tqso much....
i just receive my digitizer today... but i have no idea to repair it myself...can u guide me?
We took my ks20 apart. The screen opened up a bit when it was removed, so perhaps it's broken. We did manage to get the digitizer off however..
Problem is the digitizer was glued with a helluva lot of glue. How will we get it to stick when we put it back? I read some use double-sided tape, but won't that be way too thick?
Glue seems to be the only solution, but what kind and how much? The screen also seemed to have been glued in place.
Will any kind of super glue work? Only a couple of drops perhaps? I'm pretty sure the phone won't be tight after this but..
Anyone who's done this procedure.. What did you use? We're gonna finish this tomorrow so I'm very grateful for any advice.

This is important.

TP2 Screen not responding

Hey Gang!!
My Tilt2 (TP2) was acting sluggish the other day and then the touch screen would not respond to anything.
I did a soft reset ... didn't work or solve it ... so I just went ahead and did a hard reset. Even after doing that I have no response from the screen.
The screen shows up everything .. I can view the time, people calling me but it just won't pick up any touch activity at all.
Has anyone ran into this ? or what would you suggest.
Just need some help !!
Thanks !!
TarkuS
I just got the same problem. Wich rom are you using?
Just what came with it from AT&T ... factory settings back on it now.
6.5 winmo
had never put a different ROM on it.
Your digitizer may be dead and in need of a replacement
I just got done searching something's from google and other people who have had the same problem and tried one thing.
The outer rim where the chrome area is , they said to clean or see if there is crap/crud in between the screen and the chrome area.
I did that and it seems to be working ok right now. Just have to be careful. I used my thumb nail to slide in between that area but you might want to use something thinner to be on the safe side.
Thanks, that worked for me also. bit strange solution but isf it works...
the crud you collected must have been pressing the digitizer down in multiple spots or even just ONE spot which led it to think there was already a "touch" on it.. hence not working when you would touch it else where.....
There's been issue's with cases doing that where they are too tight and the screen is picking up that pressure as a 'press'... it's odd you guys have collected that much stuff to make the screen act funny though... messy pockets for sure!

I'm not believing this..but it worked. Thanks for posting this. I was getting quite desperate!
TP2 screen not responding.
Thank you. Cleaning around chrome area worked, but I lifted the plastic contact a bit, so future users of this method should be careful. The contact lifted above the buttons on the bottom of screen, so I will have to be cautious not to get dirt in further.

Touch screen has stopped!!!! Help!!!

My phone has been going great and giving no issues. Byt the other evening suddenly the toicuh screen stopped being responsive!!! Totally randomly. No drop or spil or anythign like that, no new software or roms recently.
When you open it the keyboard still lights up, and after a hard reset, you can navigate a bit using the keys. But ZERO response from the screen!!!
As i say, this is even with a hard reset!!! I also tried using masking tip to pressure the screen in case somethign was stuck.
Ok it mighty be the digitiser, or a loose connection. Im hoping not.
Has anyone experienced this or similar and is tehre anythign else i can try before i take the plunge and get someone to look at it??? (its out of warranty unfort)
Ouch
Sorry to hear. It happened to me months back. It started with very uncalibrated clicks... making corner clicking impossible to compensate for.
I've recompensated, but that didn't last long - and it eventually degraded to no touch screen. With insurance, I did get a refurbish for my woes.
I flashed Stock ROM and relocked. No luck.
I'd still back up everything.
Reformat SD card.
Reflash stock ROM
Relock the device - all to see if it helps.
I did have a similar recent problem - but in this case it's because I was using a clip on hard case front that must've been putting pressure on the touch screen.
Hopefully one of these helps you out. Good luck
When my screen stopped responding it was due to a more physical thing.
I read this somewhere and tried it, worked instantly!
You have to get your finger nail under the screen (try pushing your nail into the edge of the screen from the side) and lift the screen up a bit.
This worked for me. If you think its a physical and not software issue give it a shot.
I have had the same problem.
I bought new touch screen on ebay (about $15) and after replacement the device works well.
stop everything !!!!!
if you have Google G Mail set up on your phone remove it and it will fix it's self
somthing google / G mail is doing the tilt 2 doesn't like
causing the "Sleep Of Death"
Hi guys
I have tried all the above
Last resort is i got sprite backyup to work
BUT HOW THE HELL DO YOU HIT "NEXT" OR "OK" FROM THE KEYBOARD AS SCREEN DOESNT WORK????

Below is one more post on this topic from another forum:

Eventually, the glue lets the screen slide into the center of the phone, until the digitizer actually touches the screen - and then, the digitizer stops working.
It's actually very simple to fix - slide a finger nail under the plastic by the speaker and gently pry the digitizer up. Then, put it back. You dont need to remove it totally from the phone. It will flex back to its flat shape as soon as the glue releases. As soon as you stick it back down, the touch screen will work again.

Bubbles under digitizer? No screen protector

Hi all. Quick searching leads me nowhere as there are thousands of problems concerning issues I'm NOT having. Sorry for the crappy 3ds camera pic, it's the only thing I have at my disposal right now besides the phone. As I said in the title, I'm not using a screen protector - this is a stock phone right out of the factory with no accessories, albeit aged a bit.
If you'll take a look, you'll see two screen bubbles. The huge funky-looking one at the top started out looking like the one at the bottom, and grew over a period of a few weeks. The bottom one started out really small and doubled in size to what it is now, but has since stopped.
It's really annoying and starting to bother me, but I was wondering if anyone had experienced similar issues, or has any input whether or not I can maybe fix this thing without having to get a whole new screen/digitizer/whatever. No replacement plans on this phone so gotta figure something else out. Any idea what's going on?

Is the plastic actually raised up? Can you see it when the screen is off? To me it looks like the digatizer may be going out, but its hard to tell from a pic.
It appears to be sealed and working fine... just has bubbles. I don't really know much about the insides of this phone, but it almost looks as if whatever is behind the digitizer is slightly warped and might be causing some contact with the glass or something like that. Reflections (off what is behind the screen - lcd? Not the reflections off the glass) tend to bend near the bubbles, whereas everywhere else behind the glass is pretty straight.
Essentially it just looks like water droplets or air bubbles forming on the inside surface of the glass, but it's never seen water before. I don't think the digitizer is failing.
Same problem, can I fix this myself?
Hi guys, I have the exact same problem on my HTC Desire. Touch is working fine, the pixels underneath are ok... yet this thing is expanding. What used to be 3 little bubbles near the very corner moved and turned into this amoeba looking thing after a few months.
Here are a few other shots.
Hope someone can let me know the possible verdict? Is it gone? Can it only be repaired by a professional or can I expect to be able to "clean up" the inside of the screen if I dismantle my phone as it is done here?:

Maybe the liquids from the lcd are boiling from the heat? Sounds dumb but is a possibility

Yikes. Mine is still having the same issues. I'm thinking about just tearing it down soon and figuring it out myself. A little nervous working on something with such small components. Any tips for a first teardown? I need to get a T6 torx and I've already looked at a couple disassembly guides, was a while ago though.
As far as I can tell, I will have to replace either the digitizer/glass or the LCD. If it's the latter I'll probably just upgrade the phone cause they seem pretty pricey.
Ok, I did what I said and investigated myself. Unfortunately, I broke my phone doing it.
The problem is the front glass/digitizer. I couldn't get the LCD off, but I pried it back enough to see bubbles through the glass looking from the inside.
I broke my LCD prying on it, now I have an ugly black spot. Guess I'll be buying an LCD and a digitizer now. Anybody have some spare ones, or know the cheapest place to get them?

There are some digitizers on ebay for about $20 USD. i dont know about LCDs cause i never needed to replace mine but i would assume that they would be a little more expensive. Also, make sure you get the digitizer WITH the bezel because it will make your life a ton easier.
I'd better not touch it then
Sorry to hear about your LCD, D-Lew
Guess I wont be touching mine on my own. I'll definitely break it trying to do the same thing as you. I wonder if it's gonna break my phone if I just leave it as is. I mean, apart from the fact that it is there, it is not affecting the performance at all.
The bubble might get bigger. That's all you have to worry about.
