Problem: Flickering Screen - 8525, TyTN, MDA Vario II, JasJam General

My father's Hermes has a problem, maybe you guys can help: Now for the second time the screen just began to flicker, as if the picture was interlaced, and the colours are off (see attached picture). The second time it happened while the camera software was running, but without obvious reason.
The first time it happened a hardreset (but only that) helped, now the second time even a hardreset doesn't help. Interestingly the screen was ok for a moment after the device was switched off over the night, but after 2-3 seconds the screen began flickering again and it didn't stop yet. Any ideas what this might be?

Ok, I found this out: It seems to be a hardware problem, because when I open or close the device with a hard push then sometimes the screen gets ok again, and other times when I open/close it it starts flickering again. So I should open the device and take a closer look at the connections between keyboard- and display-part of the device (or, regarding my repairing skills, maybe rather take it to the repair center...).

White screen of death

Well its happened... after 1 and a 1/2 years of keeping my m3100 safe and sound I dropped it. Fortunately the cosmetic condition is still good. Unfortunately its started to give me a 'white screen of death'. Has anyone else encountered this?
What happens... I turn on the phone and go about using it normally and then after about 10 mins the screen slowly turns white. If I press the power button on and off a couple of times it clears and I can see again. The OS / phone functionality is fine and keeps running. Along with the white screen the buttons on the front freeze at the same time.
Its all leading me to think that something in the screen part of the Hermes has come loose or been damaged?
Help anyone?

An issue in which Jasjar displays mirrored Screen

hello XDA community,
I have here an imate Jasjar which after a screen upgrade is displaying the image reversed. It did not begin like this,
Upon first booting up the device after screen upgrade, all was fine, screen displayed normally. About a week after this, the screen began flickering, not on/off, but instead, reversing the image shown on the screen. (a mirror) effect. I did not know what to make of this. I delt with it best I could.
A day or two after this flickering began, the screen began to remain in this reversed image mode, which I did not enjoy. The same day, I had dropped the JJ into a tub ( a pretty hard fall), but somehow, by the grace of god, the water failed to enter the inside of the Jasjar.
After the fall, I had noticed that the screen had stopped its flickring antics and remained normal for about a week and a half. It is now displaying a reversed image only.
I now am unsure of what to do, I searched throughout the XDA forums and discovered that performing a hard reset should repair this.
I suppose my main question is, is there a registry tweak I can perform to revert the displayed image back to its original state
Many thanks to all who respond.

Touchscreen not responding after only 2 days

After only 2 days the phone froze. After soft reset the touchscreen and the front 4 buttons stopped responding. Tried several hard resets with no luck. I left the battery out for several hours, which let me finish the calibration process. The touchscreen worked for about 30 seconds, now it's dead again.
It's running the stock Dutch rom. Provider says they can't replace it and repairs can take up to 4 weeks.
Is there anything else that can be done before I send it back?
I don't think you have other options... if you have done a hard reset and still not working, send it back.
I figured i'd try to turn it on one more time before sending it back... what do you know, it works better than ever now (for 1h at least). This thing is driving me crazy.
Does anyone with more knowledge about touchscreens have any idea what might cause the part that's detecting the taps malfunction for a period of time and then fix itself?
I have another problem, I can see the sensors of the touchscreen (they should not be visible) even when screen is turned on. It affects image quality, because I see small green dots when I have a white background, it looks like dust and when I try to remove it, I realize it's not dust...
Still don't know if I should send it to the service, because it would take 4 weeks and I don't know how the world-warrant works. Hope you can resolve your issue or have a better tech.support near you.

Touch Response Problem

I have a Sprint Touch [Vogue]. It has served me very well up until recently.
One day, I was using my phone normally when the battery died. No big deal right?
Well, I charge my phone and reboot it. For some reason, Windows is EXTREMELY slow and unresponsive. I figure that something vital had been corrupted by the battery's death, and that it was nothing that a hard reset couldn't fix.
I performed a hard reset.
I let the utilities for the first boot run to customize the phone. Everything seemed pretty much normal. I configured my settings, re-added my contacts, etc. Then I turned the screen off [with the power button].
I turn it back on later to do something. I touch the screen. It immediately and accurately detects the touch's location, but it continues detecting a touch. For 20-30 seconds, after the input has stopped.
It was strange, so I soft reset the device. It booted, with the same problem. So I performed another hard reset. I did some configuration [the response acting normal at this point], and then turned the screen off. Turning it back on brought the same problem back.
This problem still exists on my phone, even after numerous hard resets and even ROM flashes.
A better description of the problem: When the device is first turned back on [meaning brought out of standby], its touch response is messed up. It will immediately and accurately detect any touch input, but it will continue to detect the input for up to 30 seconds AFTER it has been released, as if you were holding it the whole time.
WHY is this???? My phone is almost unusable because of this!!!! I can still place/ receive calls, using the navigation buttons and the red and green buttons. But the touch response is screwed!
Can someone please shed some light on this problem I'm having?
Phone specs: Windows Mobile 6.1, HTC / Sprint customized. Minimal third party software is currently installed.
[I've already determined that third party software is not the problem, because i haven't installed any!]
Possible solution
Hi,
today I experienced something similar to your description - no touch response when I tried to pickup a call. The strange thing is that last night everything was working and no settings were modified nor programs were added/removed. The screen suddenly 'died'. At the moment I am using it through a program MyMobiler which brings the mobile display to the PC and I can use the mouse to control the phone (it is like VNC for the phone screen, the phone is connected with ActiveSync).
This is temporary solution untill I finish my backups of files, programs, settings. I didnot performed hard reset yet, hope this will solve my problem
In the following link there is a 'magical' solution - to remove the screen protector:
http://www.htcwiki.com/thread/1112981/LCD+or+Touch+screen+not+working
P.S. I had removed the screen protector and voilá - the screen is now touch responsive. The root cause of the problem obviously is the dust between the screen and the protector which results in constant screen pressing - and as a result no accepting my finger presses.
I hope this will work for you and others with similar problem.
I had a similar experience with an old Vogue.....In my case, there was no battery death precursor, but it just started acting up. Not too long thereafter, I noticed the screen/digitizer was forming what looked like an air bubble between the digitizer and the LCD on one place of the screen. The screen was becoming defective. I eventually had to buy another Vogue from a friend who didn't have a clue of the 6900's potential, and didn't want his anymore, so I got it cheap.
Sounds like your screen/digitizer may be on it's last leg.

Generic chinese head unit; touch screen sometimes unresponsive!

I would greatly appreciate your help. I have this generic Chinese made car Head unit (running android jellybean 4.2.2). I've had it for about a year and a half or so. A couple of months ago, the screen began to be unresponsive - after boot up. It is quite frustrating, as the unit itself is actually working.. but the screen just does not respond. This happens randomly! Sometimes you have to restart it several times before it works normally. And it does work normally sometimes, though there is no way to know for sure when it will work or not. So it just seems to happen randomly. Sometimes it will not work at all after several reboots. Sometimes it will just work the first time it's turned on!
. It seems to just be quite random. I tried using one of the screen calibration apps from the appstore. It seemed to make a very minor difference (or perhaps not!). The problem is still very much there.
Sometimes, while it's unresponsive, if you touch an app icon and leave the unit alone, after some time the app would eventually open - though the time it takes to do that greatly varies. At this point, the screen may then work - sometimes normally, but in many cases, abnormally or unpredictably. In some cases it will not work at all.
Please does anyone know what is responsible for this and if/how it can possibly be fixed?
One more thing I should add is that I suspect this started to happen as a result of an unsuccessful attempt to root the device. Could that be the reason... and/or is there any hope... i.e. can it possibly be fixed?
I have also done a factory restore.. but it still does this! Please help
Did you ever get any answer to this?
Best thing I would recommend would be to disassemble the unit remove the ribbon cables carefully be very careful removing the latches the plastic latches on the Zero Force connections and then make sure they're clean reinstall when it boots plays Five Fingers flat on the screen for about 10 seconds and it'll give you the touch calibration screen with four dots touch the dots from one then two then three then four then it'll give you the option automatically to save it and then let you calibrate the touchscreen hit configure start and then do each button one at a time touch the screen and then the left side touch buttons starting with power and then ending with volume down and that
