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

Sliding Keyboard Issue

So today my Titan started acting up. When I slide the keyboard out the screen freezes. I can still type by nothing will show up on the screen until I close the keyboard.
Also If I hold the keyboard halfway slid out the phone will work normally(but can't type with half the keys), however once I go past a certain point the screen freezes?
Hardware or software issue? I'm debating a reflash.
I can see these thin metal wires inbetween the keyboard and screen when I slide it out, I wonder if it has something do do with these.

Well the reflash didn't work. I took the phone apart and still can't figure out the issue. Seems like it might be with one of the cables connecting to the LCD screen.

I have literally the same EXACT problem. Have you gone to WM 6.5 beta yet by any chance? I started having the problem and numerous others when I went to 6.5. Idk, if you figure it out please tell me. I will be trying to fix the problem too.

Well, I have found the reason why mine wasn't working properly. My flex cable attached to the screen that goes to the actually phone motherboard is ripped. Would anyone happen to have one??? I can't find any on the internet. I have searched everywhere. Please help. Thank you!

Has anyone dismantled an X1?

Hi,
Just wondering if anyone has fully dismantled an X1 - and if so, do you know if there are water indicator stickers on the inside of the phone?
So far, I can see two on the outside (one on the battery itself and the other where the battery contacts are on the phone itself)
Thanks in advance!

some where on youtube there is a vid on dismanteling an Xperia

It doesn't appear to have any on the inside.. however I'm not sure if the 3 rectangular white things on http://www.phonewreck.com/wiki/images/thumb/a/a8/Xperia_x1_pcb_2.jpg/800px-Xperia_x1_pcb_2.jpg are teh same as the water indicators on the outside.

Yes Dismantled it.
Mine fell down. Touch stopped working and so did the finger scroll sensor. The touch worked in landscape but in portrait it wont work.
Opened it and found the connector slide cable (similar to ones in samsung slide phones) unplugged. Guess the shock of the fall made it stick out.
Anyways plugged it back in and whoa....Phone was as good as new.
For thoe whose touchscreen stop working, I suggest please first try the "BOAN" method. (Battery off all night). Insert the battery in the morning and the screen works miraculously.

Or make a hard reset may i add...
Or full flash instead thats worked for me...

Hard Reset did not solve my probem though. I tried flashing to Generic R2a0010 as well. Did not work.
One more thing before i tried the BOAN methodm was inserting a visiting card between the screen and the casing especially the four corners to wipe out the dirt. beleive me, its the small particles that pile up and sometimes pressurize a particular point disrupting the touch mechanism. I got my X1i only 20 days back, and i stay home or office and believe me there was enough dirt residing in the corners. I was actually surprised why they had such a big gap between the screen and the casing.
Anyways, since i did the flash, I flashed mine with the latest R3A0010. All's well in my x1 except that custom ringtones are not loud enough.

[Q] Screen flickering, what should I change? Screen or Motherboard?

Hi guys, if someone here suffered from this kind of flickering >>VIDEO LINK.
How do you managed to fix it? What part did you change, the screen or the motherboard? Thanks. Really need some help. My phone now is unusable.
]]]]]] UPDATE 1[[[[[[[
Hi guys, just got my G2 back from the dead.
I send my G2 to a phone care in the city and they said my lcd is the problem, they changed the lcd+digitizer (the whole half of my G2 )and now the problem is gone. But When I got home I noticed vertical lines on my G2 when it is turned off, not really noticeable but if you look closely you can see the vertical lines and thinking that they change it with a low quality LCD. Even in white backgrounds you can see the lines but only if you have a clear eyes . I compared it to the original LCD and I don't see any vertical lines at all, it's all black. But the frame of the new lcd is solid like the original. So, in the future, will this new LCD survive or should I go the phone care again? Thanks!
***********UPDATE 2************
[UPDATE]
I think my G2 is working now after playing games for hours in 5 days, no flickering/stuttering/jittering noticed.
But, my IMEI was change and it was rooted jellybean when they give it to me. I don't know if they change the motherboard or the whole phone except for the body case and the new screen i purchased. I asked them about the changes of the phone because it's my second time returning the phone and the women on the counter said their tech just adjust something. I don't believe that, and then I saw the IMEI changed. I didn't ask why my IMEI was change, i'll wait til something goes wrong on my G2 and sue them. LOL.
I have some questions regarding this.
1) I'm not really sure if how an IMEI was change, is it for changing the motherboard?
2) Is it legal that they don't tell me what they change on my phone?
For now my G2 is still alive and no problem after upgrading to lollipop + root + twrp. Hope it goes all well now.

i went to lg service and they changed some filters on motherboard in 2 hours filter,EMI/Power 2 quantity i read on the paper. i was on warranty..

That looks crazy, it definitely would be a motherboard issue, or, I had a simliar issue while repairing them (I've re-sold about 20 of them) the flex ribbon sometimes gets dirty, or out of place(the one on the bottom under the speaker). You have to remove the back, then remove the speaker(6 screws I believe on the bottom, it;s an L shape). Once you do that, make sure the square flex cable is connected well, and there is nothing touching the circuit right under it(It has a plastic tape to keep it from touching).
The connector I'm referring to is right next to the USB one on the flex. For obvious reasons I got the image from ETrade supply. You can clean the connectors with 91% or higher alcohol, DO NOT use anything less.

I think i'm out of warranty because i bought it when it was newly released. Do you think lg sc will fix it by paying them cash?

When you replace your lcd they always tell you to make sure you have both connectors securely in place above the usb connector. One of them is the ground connection to your LCD!
Make sure both are fastened correctly and test before you seal your phone back together.
Keep us posted

[UPDATE]
After few days of youtube and playing games, my phone started stuttering/flickering again like on my first post -_-
I paid for the new LCD that they change, should I pay another bucks for the motherboard problem? or they'll give me a refund for the new LCD I bought that didn't fix my problem? Please someone reply me asap. Thanks

This error is on mainboard. Fix it is very simple. I has lot about 10$ for this solution.sorry bbecause my english's bad.

Hi guys, i have a similar problem. I bought a new lcd on aliexpress.....that is the video of the problem....
http://www.mediafire.com/watch/glzqihgdzz12jsj/Lgg2_lcd.mp4
The strange thing is , not in every operation make the same problem. after days i see that problem usually on facebook and a lot on clash of clans .
I make also a screenshot on the clash of clans and when i open the picture the screen flickering .....
its like when the phone show some combination of color make this problem

My Lg PRO 2 Phablet did the same from first turn on, flickering on and off, very dissapointed as i had mine direct from Hong Kong and couldnt send it back. What i did was to tak all of the screws out and take the plastic back off, then re fitted the back only, no screws and turned on, no more flickering. Then i put a couple of screws in and tried again, still no flicker, then after a couple of more screws by the sim socket it started to flicker again! Now i just run the phone minus a few screws, it must be a pressure thing!

Hi, i have exactly the same problem, specially in combination of colors (green red and blue most of the time). how did you manage to fix your phone ? did you change the mainboard ? thanks for your help.

Half Static Screen - Connector Not Loose

Hello, I have had my Axon 7 for just over a year and two days ago the screen went suddenly half static despite the touch still working perfectly. I looked up the issue and saw that this is pretty common and that my display connector was probably loose, so I opened up the phone to make sure the connector was fully connected. Well, I booted the phone and the static was still there, so I unplugged and reattached the connector, but that didn't help either.
Given that ZTE is bankrupt and my phone is out of warranty, is there anything else I can try at home to fix this or is my phone screen just dead? I'm in California, is there anyone who could possibly fix it in the state?
Thanks for your time!

Try pushing the connector down while it's booting and see if that fixes it.

Alright, I'll try that. If it needs constant pressure I'm probably going to need to glue it or something?

Tape could also work. I added tape to my back up Axon so it doesn't happen again. You could also add something so the frame can push against the connector.

Hey, unfortunately, pressing on the connector doesn't change anything with the screen. I even tried disconnecting it and cleaning out the contacts with a can of compressed air. None of this helped.
What are my next steps? I'd really love to get this phone working again.
Thanks!

Probably playing with the wrong connector, the half static screen is common problem, ZTE repaired mine a month ago as they are still actually operating. They said it was a connector and that they put something in there to make sure it doesn't move again.

Hey, that's possible, though when I unplug this connector the screen goes completely dead. Here's an annotated image of the connector I've been messing with and the foam pad that was installed on the back of the phone, I believe to keep it in place (my phone was bought in March 2017).
https://imgur.com/0d7C2xc <- That's an Imgur link to the photo, I can't seem to get it to show up as a hyperlink or embed it into the post.
Is this the wrong connector?
Thanks!

Yep that's the connector. I'm sorry to say but it looks like the screen is toast. I seen some Samsung Galaxy S7's that have the same issue but couldn't be fixed without a new screen. And since the Axon uses a Samsung screen, that might be the issue.

Is there a place to get Axon 7 parts? I am not planning on using it as my main phone again, but if I could get a working screen I think I'd use the phone for something else. Are there any other screens that use this connector?

Aliexpress has screens for sale, they came down in price the last time I checked.
