touchscreen not working anymore :(

hi there
as of yesterday i accidentally dropped a jack splitter (like this one.. (click here) onto my pda2 from 1 meter..
at first i thought everything was okay
but then i realized that the touchscreen was not working.. the buttons are working..
though i hesitated that it'd never work again, after taking my imate apart and after i put it all together it worked for 10 mins.. then it stopped working again.. this morning it did the same, worked then stopped..
so my questions are:
1. can it be something other than the touchscreen? there is a small dent on the screen but the image on my today screen is displayed correctly..
2. if i really have to change the screen where would i buy 1?
i found this one but i want to have more options if there is

thanks...

Touchscreens are replaceable but make sure you buy the correct one, as the screen in Alpine is only one of 2 that could possibly have been fitted in Himalayas i.e a touchscreen for an xda2 is not guarenteed to be compatible with the LCD you have.
Depending on LCM, you could look into a repair of the exisiting digitiser, is the screen marked in any way where the item hit it?

p.s don't bump so quickly - do your research more thoroughly - you're not the first person to suffer this problem...

yes there is a small dent on the screen
i know i searched the forum but maybe i'm searching with wrong terms.. not much came up.
i don't know any other websites than the pdasmart.....

Then you need a new digitiser, the gap between the touchpanel and glass in the digitiser is reduced where the dent is, so the resistance properties of the digitiser have changed at that point i.e it will think you are always touching that spot. You could remove the plastic overlay, heat it gently and try and bend it back / flatten it but I've tried and never managed to do it
Most places only sell the entire LCD / touchscreen assembly, cheapest I can get for an alpine is about $140 USD for the lot, perhaps check ebay for a unit with a broken LCD?

XDA IIi Screen alignment trouble

Hi all
I have a problem with the screen alignment on my XDA IIi. I can get through the alignment tool fine and the 5 points match up correctly - however between the 5 points things can get quite far out of place. I tested this by trying to draw straight lines in notepad - the lines were very wonky, except for the sections near alignment points.
I was wondering if anyone knew of any software with more alignment points or any other possible fix.
Thanks in advance.

wow...rare case dude...never heard of anything of that kind..i guess you must have dropped it or better yet try Performing a hard reset, it may solve the problem...you must have installed a program that cause it to behave this way...

bushako
and oh yeah dont forget to back up,hehe

Yeah tried a hard reset... still no luck :\
I wonder if i should open it up and have a poke around.

Before you do that you might want to read on how the early Hermes were fixed, ie sliding a business card around the frame of the screen.
However, from personal experience, I once screwed up my touchscreen by sliding a screen protector up too high, so be careful. You might just open it up and take your chances there instead
Check out a service manual if you have access.

Dude did u get it fixed..i think im facing the same problems now...when aligning the screen the 4 points match up correctly but also wen i draw something using 3rd part programs like pocket artist..id try to draw a straight line at the bottom of the screen and instead it appears curved..and when typing messages i always end up inserting the wrong characters even though i point at the correct letters...i tried swapping a telephone card inbetween the screen and the panel but it didnt make much difference...i can open it up and take a look but i dont think much can be done either...so if anyone else is facing this problem and have resolved this issue..please let me know...

yes, same as me.
whenever I tried to hit space bar, the button above the space bar will be pressed instead :-(
can anyone come up with the solution on this device problem ?

anyone got a solution for this?
I am experiancing the same problems basically I think the manufacturer installed protective screen has come loose from the hard sensor (due to use?) and so the stylus is pushing on an air bubble.
I dont know whether to cut out that layer with a scalpel (carefully or not) and use normal screen protectors that stick properly ... has anyone done this before?

Yes, you could be right relbourn, at first I was suspecting the screen protector causing this problem but
hm.. I've tried even to remove the screen protector and did HARD RESET as well but still......... the problem can't be solved :-| gees...
any idea ? instead of replacing the touch screen ?
any suggestion or similar problem with this ?

Lower part of digitizer not working

Hi,
My friend gave me his broken G1(digitizer+screen).
I've bought new ones and replaced them.
Now i have a weird problem that the lower part of the digitizer is not responding, i cannot open the menu button or touch anything there.
but if i hold my finger for few seconds and then let go then it will open a "quick search".. like it is responding.
is it possible that i've messed something along the way or that the digitizer was not working from the factory?
Also was wondering if there is some program to calibrate?
Thanks

Anyone?

can't help you actually, but i hope this hint helps you:
the g1 has a capacitive touchscreen, it doesnt require a digitizer / calibrating...
but as i don't know how capacitive touchscreens work in detail i can't help you...

I have the same problem :S

I have seen posts about the lower part of the digitizer not working. I think your digitizer is defective. Try wiping and installing your rom again or If you can, see if you can disconnect the ribbon connecting the digitizer to the LCD and then connect it back to the LCD, restart your phone and If it still does not work then your digitizer is probably defective. Contact the seller and ask for a refund or replacement would be the best choice.

Ye I managed to fix it.
I opened and reconnected my phone probably 100 times :S
Oh well, I hope its fixed permanently and Iwon't have to open it again incase it drops out again :S

If you just recently bought the digitizer, i would suggest you ask for a replacement so that problem would not occur again.

X1i Touch Screen Stopped working??

Hey guys,
I've had my X1i for a year now. No hard falls most falls are on soft surfaces. & Suddenly today morning woke up & the touch screen isn't responding. So I looked up posts, some said turn it off & turn it back along with removing the battery & it should work fine. Tried that, worked for a bit then stopped working again. Also tried soft-reseting & gave the same result. So is there any other method you guys know ? I'm thinking the other type of reseting..forgot what it's called but that'll delete everything so i gotta back things up first. So any solutions? & thanks in advance.

Have you got a screen protector on it? If so, try lifting the edges of it a little.

Nope, no screen protector. Does it have to do with any .cabs i've installed before ? Or they're not related? Is the battery related? Could it cause something like that?

I once run into the following, it may help you too:
after installing an app(from a cab) my screen was allmost non responsive.
Calibration didn't help.
I have "Advannced config" installed, uppon checkin the sensitivity it was waaaaay down, even under default.
Hope it helps for you too =)

i had the same problem to on my proto x1
it completely stopped working and i tried everything (reflash rom, boot android)
but all without luck so i bought a replacement screen
after a while my touch screen started working again but still occasionally fails
i have not yet replaced my touchscreen, i am thinking about a loose connector or something...
btw i was on official r3 fw

your flex cable might have worn out!

Where is that located? Where can I get a new one?

here is one thread about it, there should be others if you search some more than I did
and this would be a means to get a new one (official site, similar price), if it really is the cause and you don't like to tinker
cheers and gl

If your LCD is working, then it could be bad digitizer like mine instead of the ribbon cable. (Well, I use X1 a lot in humid place like bathroom.....). Just pay a few extra to buy the LCD+Digitizer for about ~$30 that will save you a lot headache for just the digitizer alone. There's a thread in X1 accessories forum.

[Q] Touch screen dead spots

This may be a problem beyond the scope of android, but seeing as I'm running it, I thought I'd try here first.
I've noticed that the lower left hand side of my screen has a "dead spot" where touch is simply not registered. To illustrate, I went to screen calibration's test screen and drew a straight line along the edge of the screen. (See Attachment)
I've tried recalibrating the screen (manually and resetting to default calibration) as well as wiping data and reinstalling the system. Reinstalling the system worked once, but then the problem came back and subsequent reinstalls did not fix the issue.
I'm running Incubus26jc super froyo [RLS 12] on the 15-07-10 340X480 Froyo Kernel.
Anyone else seen anything like this? As far as I can tell, the problem is not getting any worse. Currently, it's only a hindrance when trying to use keys in that region, but I can work around it by switching to and from landscape. It's a bit of a hassle, so I'm hoping someone may be able to shed some light on the situation.
I was sure it was hardware until the system reinstall fixed it, but am now baffled as I can no longer replicate the fix.
I have not tried reinstalling the kernel but will at some point in the next day or so. I'd like to avoid switching back to WM to check if the problem persists, but may have to... we'll see. Doing everything I can to make this phone last until the Incredible month of February when I'm up for an upgrade.

dont know the issue resolution... but i have the same with my touch vogue.. and in the same 'area' apparently as well.
hard for me to hit the 'a' key on my keyboard. hehe

I'm glad to see I'm not the only one... anyone else?

Bottom right corner for me... I was able to calibrate around it but it took a few tries.

The sensitivity across my screen was inconsistent some time ago. I found that years of my abuse had taken a tole on the exterior of my phone. It eventually got worse and I bought a new housing (with a new digitizer) on ebay for a reasonable price. If it is hardware then it really isn't that hard to fix if you like taking things apart.
If you're sure that win mo accepts input from that part of the screen then nevermind my post. I would play with a painting app though and investigate the hardware further.
I may be talking a little out my a$$ with this part but.. is it possible that in calibrating your screen the os may change it's settings on how hard you have to press and such also. that may be how you got it working.
In any case, my investment in a hew housing was well worth it considering how modern my old phone has become thanks to the developers here.

In my case, no - when drawing a straight line down or across the screen, the line starts 'moving' away from the stylus (like the picture in the OP).

Gah... now it's shutting itself off randomly and the dead spot has grown. Not good at all.

Yeah, mine was better for a while then 'slid' again. I ended up swapping the digitizer with my other Vogue and things are back to normal.
Sent from my Full Android on Vogue using XDA App

I have another vogue, but am weary of doing anything like that. How hard was it to get done?

All you need to do is switch the front half of the housing rather than the digitizer itself- it's not hard. There's a teardown guide somewhere in the forum, Google Vogue teardown and it should be at the top.
Sent from my Full Android on Vogue using XDA App

The only thing that worries me is that my spare vogue exists because it was dropped in a muddy puddle. I'm hoping the water damage isn't too bad. Guess we'll just have to see.

it is really annoying
I have the exact same problem and I too thought it was a hardware issue till I saw this Thread. I was ignoring it till two days ago when it started really bugging me. Now, I don't even need to press any button and it automatically gets pressed around the curve and I have a google search box there, so it keeps on searching for eee or sss randomly and started draining my battery. Is there a proper fix for this?

I thought I'd chime in too... I could never seem to calibrate the touchscreen properly in either Android or Debian. Changing the screen resolution (i.e. msmfb scaling) seems to have no effect, whether it's 240x320 or 640x480. Any area within 5mm or so of the edges of the LCD will register as the edge, making "A" and several other keys on the virtual keyboard impossible to hit. Passing calibration values to the kernel didn't seem to fix anything, but it's possible I was using them the wrong way...

i have the same kind of problem on my Kaiser... i think its realted to hardware... either the housing or the digitizer...

I am experiencing the same problem on X10 mini pro. the same screen spot exactly, i have to try very hard to get z or x or shift to work. Sometimes when I try locking the screen and unlocking it back, it works.

update
so after a very long time with this problem i decided to change the digitizer and problem is gonne. visualy the broken digitizer had nothing wrong with it. The fix was fairly easy though, there is no glued parts involved into getting a new digitizer on the u20i.

Touch Screen
I just bought a brand new Cubot One and it looks more than perfect! It has just a little problem with the touch screen ( I think its the software, need ROM change). There is a dead line on the right side of the screen that touch doesn't work at all. Any solutions? Anyone faced that before? Can I fix it myself or do I have to send it back for replacement? Is there any video or guide that shows its done?
I uploaded a video on YouTube to show the problem but i cant post it yet.. (new member)
You can write "Cubot One touch screen problem" and it's the 1st one.
Thank You!
