After searching for answers... Screen taps not responding

Hi there. I picked up an important call whilst in the shower. Very little water fell on my Kaiser but I belive that this caused the screen to stop working. Or I have dropped it as well.
Now I tried the business card remove dust particle trick. Didn't work. So I disabled cube / Touchflo. Then I reinstalled my ROM. Basically, I can't align the screen... I tried using the Remote Screen Alignment tool as well.
What's weird is that when you leave the phone for a couple of seconds, the battery conservation feature kicks, and when I touch the screen, the screen powers back up. So I know the screen works but just not properly.
Do I have to replace my screen (or just the TOUCH component of it)? I'm not too good with hardware but can I take it apart and fix the problems?
EDIT: For those facing similar problems, use the trial version of SOTI Pocket Controller to work on your Kaiser remotely.

I'm sure someone knows what to do... please help.

I had the exact same issues you were having, I had to send it in finally so I hope it is warrantied.

nope, its out of warranty. I'm thinking of using pocketpctechs or some other similar service. Any suggestions?

I would just order a new screen and replace it yourself.

Did they replace the entire screen or jus the TOUCH component? I heard that the TOUCH surface is way cheaper.
Also, I'm not too sure how to replace it myself.

when my tilt was in warranty they just gave a new device but on the call they said the screen was dead even though it displayed and had minimal responce.
I could be wrong but I don't think it would be easy (if even possible) to replace just the touch surface of the screen.

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

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.

G1(Dream) Touchscreen HELP!!

I was flashing a rom the other day (that i had flashed in the past and worked fine) and then i noticed that the touchscreen did not work. (everything else worked)
i flashed back to the cyanogen rom and my touchscreen still did not work.
(when i say my touchscreen doesnt work i mean that i cant touch anything, not even the android to set up my phone)
the trackball works but i am FORCED to touch the android and i cant
ive been flashing and still no luck, any ideas on what happened to my touchscreen or any ideas on how to fix it?
please help!!

I've seen a few of the threads. More than likely your touch screen has died (hardware issue - not software) and I'm not sure if that's replaceable.

Ask a technision :/ like the guy above said its proble the tS died may need replacement or ribbon isnt connected rite .

So whats my best bet in going about this?
i dont know what to do :/

if you feel like your able to take apart the phone and replace the screen, you could always try it. either that or buy a new phone or possibly a cell phone repair shop if you even have one.

i decided to kinda drop it.
it works now...
thanks for your help anyways guys!
D:

I wouldn't be DROPPING it to fix it...
Problem is probably a badly seated ribbon cable, which means it is STILL not well seated and will probably happen again.
Look in the screen hinge as you're sliding the screen open -- see the little ribbons in there? Probably got yanked a little.

[Q] Help me solve keyboard mystery please!

So here is my story.. i have a perfectly working kaiser, and one with a broken lcd.. but both of them are in terrible cosmetic condition.. so i decide to order from ebay a full housing (with keyboard included) to make it look good and give it to my brother as a present..
I perfectly disassemble the device with the working screen and easily install it in the new housing.. but when i turn it on i realise that the only working hardware keyboard buttons were q e u o f h l and some arrows i think...
My first conclusion was that the keyboard included in the housing was not working correctly so i decide to use my old one. but to my surprise the old keyboard also has only the same working buttons!!!
after that i also tried the keyboard from my other kaiser ( with the broken screen) with the same results.
So up to this point, i guess it is safe to assume that the keyboards have no problem.. but then the mystery grows cause i exchanged every single piece of the phone with the broken kaiser's parts and the problem remains the same...
Any idea?? i am an engineer and problems like that that i cannot think of a reason that they are happening drive me nuts!!! please help me sleep at nights..
thanx in advance!

Hooray! Someone else who has the exact same problem as me! The phone I have had the LCD screen replaced and once it was reassembled, the keyboard is wacky. I tried reseating it and the same keys you mention are the only ones working: Q E U O F H L, CAP/Shift, Tab, Space, Enter and the 4 arrow keys. Nothing else works. I'd love to see if anyone has a solution to our problem. =)
Also, I'm not sure if it does it for you but the backlighting doesn't turn back on once it goes off - even when pressing the working keys. I found other posts on this forum with similar problems (with no replies) but their keyboards were not working at all. There has to be a simple solution that we're missing if it's this common.

Thats really weird that we have the same keys working... it really has to be something we are missing... but i have changed everything..
the only thing i didnt change is the lcd, so now that you are telling me that this happened only after you changed the lcd, it got me thinking that maybe the lcd is not as inocent as it may seem... cause,ok, my first thought was like wtf the lcd couldnt mess up with the keyboard.. but now that i think about it it is the only thing i havent tried to replace.. i have a broken one but still quite operative, so i will try with this one and get back at you.. if in the meanwhile anyone else knows something or has an idea, please help a little bit!

Like you, I cannot find any reason between the keyboard and the screen that would cause this. They're not connected in any way or share any cables. They connect to different parts of the main board... there's no logic that I can find.
I got mine second-hand and the original owner said she had the LCD replaced because of a couple dead pixels. The keyboard was working fine before that. Let me know what you find out. I was planning on ordering a replacement keyboard assembly from eBay but since you've tried a couple, that saves me from wasting that money.

Unfortunatelly the extra LCD i had was not operating at all, so the test i wanted to do failed, and i still dont know whats causing the problem... i am more or less convinced that i have to buy a new lcd but it is a bit of a risk to change the screen because some buttons on the keyboard dont work, dont you think?? anyway i am wondering y nobody else has nothing to say... this hasnt happened to anyone else??

thank you for your reply! but i don't understand how this would help for our problems..
i talked with htc yesterday and they told me it couldnt be the lcd, but during the lcd replacement probably the flexiboard was a little torned (needs a microscope to be verified..) i am giving it for a free test on monday so i guess i l have a more detailed answer soon!!

Hmm, that's an interesting find. It's odd that the same problem exists on different phones, unless it's a common section/piece of the board/assembly that gets damaged. Are you going to try and use the assembly from your other phone? Let me know what happens. I'd like to know what piece I need to buy to get mine working again. =)

Screen Flickering

Hey guys
I have a very strange problem with my Huawei P10
About 2 weeks ago, I noticed that two purple horizontal stripes are appearing in a 3-4sec sequence
Normally, I would immediately ask for a repair, but there's a thing which persecutes me: it only happens when I don't touch the screen for longer than 3-4sec
When there's a continuous contact with the screen (e.g when writing a message) nothing happens, everything is fine and dandy, but whenever I leave the screen for itself for 3 or more seconds (e.g when watching a movie), the stripes start to appear every few seconds, and continue until the screen goes dark or until I touch it again, but after touching it it still takes only a few seconds for the stripes to sequentially flicker again
Here's what I've tried so far (no result):
- safe mode
- factory reset
- cache partition wiping
- cord input deep clean
What may be the reason?

Hey.
It's 100% a board or Display issue. send it for repairs. but i believe maybe you've dropped ur phone. Anyways Huawei knows better.

It's quite complicated
I once dropped it, but even after that, the previous LCD worked fine, there were no errors other than broken glass, so I guess we could exclude a board issue and lean toward your second option, as now that the LCD has been replaced, the fault occurs
What's more, I noticed that if I press the Home Key, and then put my finger in the bottom right corner and hold it, I can still use the whole LCD space without the flickering (I need to press the Home Key first so that it works after I hold my finger in the corner)
It's like the LCD needs to be in contact with your finger all the time to avoid that, which has led me to an idea: would a tempered glass solve that maybe?

I can't really answer for sure but i believe if there's a Huawei service center in your city and you try to fix ur broken huawei, your wasting your time. Whatever solution u apply on ur phone its just gonna be temporary since u hide your problem and not solved it.

I still think (or should I say believe ) that there's a solution which doesn't involve another screen replacement
As for your "temporary solution" mention, I guess if I found one, it wouldn't be temporary, since the fault doesn't progress, it's been the same for a month or so when it first occured, which gives me another reason not to replace the screen and keep looking for other possibilities
I don't need a Huawei service center, I can replace the LCD myself (didn't do that the first time though), but it still involves spending money, whereas I've been looking for unpaid solutions the whole time; getting a new LCD is an extremity

You can ask them to diagnose it and tell you about problem noone makes you pay for a lcd. And after reading your message over and over (And since i repair TVs and everything with electronics inside) i think it also can be your touch or display controller ic. Mostly it could be from touch ic since screen works fine while its in touch with something. But someone has to try your lcd or mb on a healthy one to make sure. which you can't do nothing like that. or do you?

@fengels did You bought original lcd, where can I buy it in good price?

I know this problem from older galaxy series like s5. The fix for this most of the time was disable auto brightness or higher the brightness on auto brightness. Don't know if this is the same problem, but it could be a try. Also don't know which cause this strange problem. Hope it can help you

No, it's a different problem, in the galaxy series the whole screen would flicker, whereas in my P10 it's only 2 horizontal stripes appearing in a 4-5 sec sequence whenever I leave the screen untouched for longer than 5sec
Playing around with the brightness doesn't solve that unfortunately, actually no in-device settings do, as I've tried almost every single option which is screen-related, like switching the eye comfort mode on, but still no result
The main reason why I'm still looking for an unpaid solution is that apart from this one error, the phone is like brand new, everything works fine

ok, so if I understad the problem shows up after you replaced the LCD display? So do you really think is more software related than hardware? I personally would send it to diagnose and repair.

The thing is it didn't show up immediately, I had used the phone for some time with no errors before it first occured
Also, since the new LCD was set, I haven't done any physical damage to it, I've never dropped or sunk the phone
Since you guys mostly advise me to send it, I guess that's what I will have to do

While you were replacing screen, did you turn your device off and disconnect the battery? and i think cleaning all cables coming from LCD and related sockets on motherboard can help. Use thinner or alcohol and if you wanna use thinner be careful so it wouldn't touch anything except golden contacts. Thinner is dangerous and affects ur phone color and plastic parts.

I did turn the device off, but I didn't take the battery off, since it's strongly glued to the phone's body, and I didn't want to damage it
Anyway, could not taking the battery off really be the reason?
As for cleaning, I did it by simply blowing out all the potential dirt, I'm inexperienced in thinner and alcohol cleaning

I am not sure butbon some phones it damages screen. I've seen this on laptops. But anyways its done. Open ur phone and use alcohol. put 2 drops of alcohol on each socket and flat cable connectors and brush it with a soft brush. u don't want to bent any golden contact. It's last thing u can do to fix it without paying for hardware related stuff.

Well, will definitely try it then, but what alcohol? Does it need to be something specific?
