Touchscreen problem

Have a "small" problem with my touchscreen, it requires to be aligned every day,and by that i mean that the alignment doesn't hold much long...that means sms typing is extremely hard when you push one letter he shows you another that lays next to it .Is it due to the touchscreen or the system....i didn't do any ROM update i still have the original software on him:
ROM Ver.: 1.12.01 GER
Radio Ver. : 1.12.00
ExtRom ver. : 1.12.151 GER
Many thanks!!

i think it it the problem of touch screen
i think it it the problem of touch screen.after extrem use of touch screen its loes the alinement for this you replace the touch screen from your hardware guy.
Thanks for all

Hi i fixed the problem with a ROM update and i didn't install extra programs that i had before like ( Pocket plus or Calendar ++...... ), anyway now i don't have to align the screen. I don't know is it the ROM update or the additional software but the touchscreen is now working perfectly.
So if someone else have a similar problem don't replace the screen right away.
Thanks

it's hardware problem.
my xda mini also..
but i know how to fix this problem.

Maybe with you it was, my MDA is now working perfectly and i don't need to align my screen every day as i did before.That doesn't mean that all have such a problem,i am only telling you my experience with it.
Best regards from Vienna

Hello, in my magician is not everyday, hapens all the time that i turn on it.
I had replace it 3 times, but i can find a good dealer of touchs. You knows one that seel a good touch?
regard's,
Ricardo

Guys,
I've had that problem for a LONG time and today i finally got tired and decided to fixed it...here's how i've done it: You just need to lift a little bit up, a few small metal pins which are all around the touchscreen (see the picture in attachment). This will force the touchscreen to remain in place and will end all your problems related to touchscreen alignments.
Regards,
Keeper

so it does help? what do these pins do?

IS THERE REALLY NO SOLUTION TO THAT PROBLEM???
(* the pins have nothing to do with the touchscreen, they are what holds aluminum shell on the plastic chasis)

i had an o2 mini with 1.11 rom and its touch screen was not quite sensitive.. had to tap or drag stylus very hard..
but after upgrading to 2.03TX.. to my surprise.. my PDA now has very good touch screen response!

hi, i have this problem
I tryed to re-flash rom or adjust metal pins but the problem persists.
Anyone have another solution?
Plese help me, i want to save my pupil

i have the same problem. the o2 is really a great little phone but i think im going to be forced to upgrade

i also got a unit mini xda from a friend, he said it is dropped and can't tap screen. i hold and press the screen, then slide up and down, side by side, and now its ok.

Probably it's problem with flat wire that connects screen with mainboard.
You need to open yours xda, find that wire, unplug it from mainboard, clean its pins with alcohol and plug into again.
From this time mine xda doesn't decalibrating anymore

Hi
My cell also had the same problem. There is a bunch of wires coming from the back of touch screen, these wires fix inside a socket. There is a black color cover that fix the wires inside that socket. During mishandling that cover got loose, that's why your cell loose the screen setting. I fixed that cover and now my Jam works perfectly. (Do it if you have the courage to open your cell)

Hello, I just bought a used O2 mini and had this same problems. I finally found a quick way to restore the calibration that goes out every restarts.
Using resco registry editor, I found the data stored here->
HKEY_LOCAL_MACHINE/HARDWARE/DEVICEMAP/TOUCH/CalibrationData
So I make 1 clean alignment and quickly went and export the Touch key into my Storage. Now every time the alignment goes haywire, I just import the data back. Hope it helps.

a very big problem with "...tap the screen..."

after months of using my device, qtek s100, after a reinstall of windows (same that i'm installing everytime) when it tells me "tap the screen..." i tap, and ask me for calibrating. I'm calibrating him, and still ask for calibrating, with no end...the problem was manifested when the windows still worked and everywhere i was pressing, it was like i was pressing on Start everytime, even if i was pressing on clock for example. what should I do? pleaseeee

hello mate, why not try to upgrade your OS

hy. i've upgrade it to 1.13 which everytime worked. then i've upgrade it to 2.03 which has the same problem. does exists another OS to upgrade?

Ady_uaic, I also have that problem and FINALY i've figured it out...
above the LCD screen, there's a thin transparent glass screen (touchscreen), which has a small ribon that connects to your phone.
check this link for a picture of it: http://cgi.ebay.com/OEM-Dopod-818-i...ryZ41343QQssPageNameZWDVWQQrdZ1QQcmdZViewItem (*)
The thing is...once, when i was opening my phone, i did a small cut on the ribon by mistake and now the screen behaves like that...I've found that if i gently push that touchscreen to the right, the ribon will sometimes bend a little bit and will make a perfect contact which allows me to keep the phone aligned...unfortunately this is only temporarely since sometimes the ribon moves and of course, the alignment is lost...So, i would advice you to check if the ribon is intact and not broken somewhere...if it is broken, then you know what to do: Buy a new touchscreen and/or an LCD w/ touchscreen included.
Hope this helps...
Regards,
Keeper
(*) although similar, do note that this touchscreen AIN'T for the magician, so don't order this one!

hello..thank you for your quick answer..i will try and i'll let you know

Sound like a hardware problem ... try flushing a new rom, if not , take it to a lab.

open up the device and reconnect the display ribbon wire properly after cleaning with a soft cloth.
the ribbon may disalign after a fall or dismantling the device and certain other factors.this is the only possible fault.if it doesn't workout, you may have to get the lcd changed.

White screen, back light off,... repaired

Dear friends
After opening my Hermes a few times I encountered the white screen, I disassembled and assembled again, the display was completely off. I thought the flex cable could be wrong. So, at first I tried to use a soldering gun to seal all solderings (Photo 1). This time the phone showed a part of display. Because, the symptom was not the same, I guest contact between the flex cable and the mainboard had problem. I used point of a knife (make it blunt first) move down to push contacts out (Photo 2). Then I assembled my phone, everything returned normal. (9h in the morning to 11h in evening to make my heart cheerful again ).
I write my experience here for someone who open their phone and encounter the symptom like me.
Good luck.

Sadly didn't work for me. Stil no backlight!

I had a problem with no backlight but fixed it when I replaced the flywheel. I was trying to update a replacement jasjam I'd bought off of ebay but when I replaced the new flywheel with the old the backlight wasn't displayed so I tried the old motherboard with the new flywheel and the backlight was on. I don't know how it affects the backlight but it did. If you can get your hands on a cheap bung phone or have a REALLY trusting friend then try that.
Cheers...

Sorry mate, what do you mean with the flywheel? English is not my mother language and what I have found in the net for that word does not mean anything to me. Can you provide me with a better explanation? I do have the same problem as the guy which writes above you.
Cheers

The little wheel on the side of the Hermes. I replaced the board That has it on it and it fixed the backlight issue.

Touchscreen doesn't work when slider open

hi,
since yesterday, my niki doesn´t response to touchscreen tapping if the slider is opened. i hear a very quiet metallic clicking sound if i open it up... if i try tapping the touchscreen before this little click appears, the touch works... but with slider open completely, it doesn´t. i guess this is hardware specific. i´ve tried a hardreset now, but still doesnt work any advice?
EDIT: i didnt flash any other radio...
EDIT2: sometimes it does work.

Sounds like a ribbon cable has come loose to the touch screen - send it back if it is under warranty, if not, Mike Channon has collected links to the service manuals somewhere on here which should show you how to correctly take it apart, fix it and put it back together again
Cheers,
Smiffy

I had the same problem. In my device it was: cable that goes to touch screen contacted metal on back panel.
I've solve it by finding manual to take my niki apart (http://www.pdacenter.ru/razborka/razbor_htc_touch_dual/ - but it is in russian). I've done everything till 6 point. Then I put my v-card between this cable and metal. Now it's ok

I've got extra service on mine.
6 euro's a month.
handed in the phone today (same issue), and got given an new one! ;D

You ROCK! I had this exact same problem happen on my NIKI100 after I put Tom's Niki Project ROM on & immediately blamed it but after flashin back to stock the problem still occured & I was really bummin! I found this thread, tore my NIKI apart to step 6 as you described & I could see the spots on the metal of the inside back of the back cover where the cable was rubbing along with the protective plastic worn off on the cable a little bit so I suspect it was touching the metal & shorting out causing the problem (heck I'm surprised it didn't do some real damage!) so I cut about a 1" length of electrical tape & taped it to the area of the metal that it was rubbing on (I didn't see any legit reason for anything to make contact to that area for a ground so I figured it was OK. I started at the edge & ended just before the gaps where you would be able to see the tape from the other side in the battery cavity) and VOILA! it fixed it! To me it looks like a nasty design flaw on HTC's part but not expecting a recall any time soon. I suspect this fix will out last the phone & hopefully this thread will help others. I am 1/2 tempted to tear apart my NEON to see if the same design exists or if they put a piece of tape in that area.

well i got the same problem as u have/had... But i also need to align my phone like ten times a day, because its always out of alignment... I think i got to get back to the phoneshop to fix(replace) my phone. I do have the touch dual for 6 months now.

Hm, same problem here. Thought first that it was an error of the ROM that I used..
Btw: isolated every contat that I could find (nearly ) but no result -> still my touchscreen doesn't work when my slide is open..
EDIT: has anyone PHOTO'S of their disassembly and isolation work? I the problem is different on my device 'cuz the cable hasn't worn off...

Ok,
Now I took my device apart to the last piece, took the display cable apart, taped it in completely and my touchscreen WORKS once again :-D.
Woot! Thumbs up for XDA-developers!
EDIT: Now my touchscreen doesn't work when slide's closed... Any suggestion?

ive brought my dual to a vodafone shop and they have fixed my dual. Replaced a part and software update, got windows 6.1 now, legal and my screen is working like a champ!

I have had the same problem with my touch screen except mine stopped working completely, it didn't matter if it was slide out or not. I could get the phone replaced on warranty though.
Just posting so people know this isn't just isolated case.

mine slowly stopped working.. im gonna disassemble later and try this. im glad im not alone
edit: worked a treat. some insulation tape on the metal shielding worked great.

That did't work for me! Can it be something else or is it the flex cable for shure? I'm considering buying a new flex cable on ebay! Will that fix the problem with touchscreen dos'nt work when slide is open?

theres a 99% chance that its the flex cable.. did you check it for any damage? mine had tiny tiny little dots with wire exposed. barely noticable but it was enough. try taping the cable. i dont know. if not, i'd get a new cable for sure.

It's worth a try. I've just bought a new cable. Hopefully it will make my
Dual working again. Now I just have to wait a week for it.

The cable arrived today and my dual now works perfect. Now the question is which phone i'll use, my dual or my new Diamond.. =)

hey, where did you get yours from? and how much did it cost?
i have seen ebay, but they are over 30$US including shipping.
Cheers,
palitu

Black screen of dead ---SOLVED!!! - in test period

First the problem.
Like many others HTC HD owners and I encountered this problem 2 days ago (i have nolonger waranty). i just was connected to my computer thru USB for couple hours, when i tried to power it on, the phone display dont comed on, but the phone worked fine (i maked couple conversations. After that i started to read about this problem, a lot of problems, but no solutions.
I try everthing - put in refrigerator (it worked until i turn off the display, pulled the battery for the night, and one bucket with operations without effect.
i install mymobiler and i was sure that my HD is working without display, then i disassemble the phone and checked the connectors, but no effect either.
i am radiocommunication and electronic engineer, and i don't give up so easily
i pulled the main board, and blowed the main board with hot air flow solder machine (i blowed exactly all over the shielding, from the bottom side not SIM card side), i wait for cooling then asemble the phone, and voala "Its alive"
NOW I AM IN TESTING PERIOD. I WILL WRITE WHEN I AM SURE THATS WORK FOR ME.
i have no pictures but i will make when i disassemle the phone again, because now is not fully asembled.
cheers!!!!!
p.s. i am sorry for my bad english
p.s. i am so happy trallllalalalalalal

It's not uncommon to see bad phone soldering on HTCs phones. Guess their factory isn't working right. Good job btw.

72 hours later everything looks great, the screen works perfektly, touch too, wireless communication too. i will post after few test again.
p.s. its look like my battery now have better handling....

6 un grande!

Wow!!! It's a good new. I had the same problem and I will try your solution. I hope it works on my phone.
Cheers!

I have problem from another type:
The problem is with signal. It was perfect until one day, the 3G has gone & then start losing the signal some times 3G return poor or strong, I take it to the HTC service center in Saudi Arabiya & the told me you have to change the main board then they do it but the same problem still there.
Now still have the problem even after change the main board, is there anything if have to change it or do it???
Note: it files down from me before this problem happened.

did you try to change the radio???

This could be caused by bad SIM card. Did you try another SIM? In my country it's not unussual for SIM cards to start malfunction out of the blue. Also, check contacts for grease or dust.

Hi, ssory for a stupid question, but what is "solder machine" with hot air flow? Is it idustrial fan? If yes, it can give to great temperature and can damage motherboard.
Was your idea to solder again all solder connections and roads?

the solder machine keep one temps at all around 280 degrees celsioum, i thunk the chips can be demaged with temture about 340 degrees, ofcourse it depends of how long time you will blow over the pcb. i don't resolder all tracks and elements (i have no such technology in my laboratory), i just blowed the shielded part of the mainboard, because i know that i can blow some smd element and they are very tiny.
p.s. i use this JBC AM6850 solder mahine
p.s.2 yes it was my idea - it is better than to do nothing with this PDA and throw it in the cupboard
The solution still work for me...

bueno suerte...

Dear
Yesterday i dropped my phone (exactly face down)- now the LCD screen show only (right side about 1 inch) bright light and remaining parts are blank. but it works fine - as when i get calls it vibrates. Pls guide me.
