Hi guys,
I have been having a very strange color banding problem with my GTab10.1 for a while now (images attached).
Here is what happened so far:
- I flashed a custom ROM after buying my GTab (ROM --> Task650) - the ROM was great and the GTab worked flawlessly.
- After the screen started to have a 'flickering / scrolling' problem (similar to this Youtube video).
- At that time, I thought it was a software problem, so I flashed a couple of ROMs (custom and stock) and another kernel (I don't remember which one was it). The problem was not solved ... I also accidentally deleted the system backup that I made before flashing my first custom ROM!!!
- After googling for a while, someone suggested that it could be because of loose connections or something. So, I opened the tablet and found the problem -> a defective LCD flat cable!
- I ordered a new LCD cable and replaced the defective one.
- The 'flickering/scrolling' screen problem disappeared... but instead, I had the 'color banding' problem!! The color banding appears from the moment I turn on my GTab (even with boot animation).
- I did a lot of search, but with no avail. I tried to flash several other ROMs, stock and custom, but none fixed my new problem!
Could this be a bad kernel / screen driver / etc? is there a way to fix this?
Any help is much appreciated

I can't see the effect you're talking about from viewing the linked screen shots - that's probably why nobody has been able to help.
It does sound like a hardware problem, though.

I have been tampering with my hero the last few days and now i have a problem. The part of the screen where the "^ phone + " is, is not working anymore. Even if i disable sense. When i'm in a game, that part works just fine. And when i press "menu" that part woks aswell.
I've put back backups wich didn't have the problem.. buit the problem persists. 'm wondering whether this could be hardware related. And what i can do softwarewise to resolve it.
Has anybody heard of a similar problem before?
(i'm on modaco 2.9 atm)
edit: when i wipe and install a new udate.zip (for instance 1.6 ion) the problem persists.
are you talking about the screen not working (e.g. a black bar, weird lines or something) or the TOUCH not working (e.g. graphics are fine, but screen is not responding in the lower area)?

Oh sorry, that was unclear. The display is fine. Touch is not working.
So, did a wipe. Did a rom update. did a radio downgrade. All these things did not solve my problem. Maybe it IS hw related? Should i contact HTC?
I also got the same problem : very few time, the bottom part works... I just sent email to HTC (in French, because I am ), I'm waiting the answer...
i have that issue too since last week. i made this video.

Often this needs sent off to HTC to get fixed, from what I've heard
Hi there!
First time I need to make a topic, as I don't find the answer anywhere..
Had my Touchpad since about two weeks.
However the accelerometer has not functioned at all since I got it.
First thing to check is the auto rotation lock -> it's turned off
Second thing I did was download a sensor visualizer app -> Seismograph.. This shows very weird results for the x-axis (see attached file), fyi, the Y and Z-axis functioned as expected..
Then the third thing I tried, Need For Speed Hot Persuit... A game that uses the X-axis accelerometer (right!?)
This works brilliant!
Other things I have done to troubleshoot this:
Restart the device.
Full reset the device.
Run HP doctor.
All have failed in resolving my problem.
As I've bought the touchpad from a french webstore (fnac.com), HP Netherlands (where I'm from) tells me I need to get back to them for a solution, as they don't offer worldwide repair (unlike ASUS for example).
Fnac.com has not answered to my request to exchange the product (2 days after I got it). And actually I just want to solve it myself if possible, bought it for fun anyways (and reading of course xD)
Any ideas how I can make the OS recognize the accelerometer?
Last thing, the auto rotation functions in the following way: Tablet is stuck in landscape, I turn to portrait, screen turns as well, but within the second the tablet is back in landscape. This behavior can be read from the seismograph screenshot.
Thanks!
Hello
I just started a new thread for a different accelerometer problem (it is just dead)
http://forum.xda-developers.com/showthread.php?t=1284760
Was wondering how you ended up fixing your problem.
thanks
Just wanted to ask you the same question...
I still have the same problem. Need to contact Fnac.fr, but my french sucks and my time is scarce. So have been postponing this. My unit actually came DOA.. however Fnac didn't respond to my request, and has now asked me to call them.. sucky service
You have no solution I guess?
Well this is odd..
Out of nothing the auto rotate function is working since today.. I noticed it while reading a PDF in Android. Booting back to WebOS didn't make a difference, the sensor is working again
I've got no clue what did the trick.. I have not updated the kernel or something like that lately.
I wonder if the sensor was kicked back into action by brute force (for instance my cat jumping on the tablet..)
Anyway, problem soved for now =D

Hi, today my tab started to show some real bad screen corruption. The colors are all garbled and the text very blurry. No matter what setting on the tab, nothing makes it right.
Last week I flashed the stock UK ICS rom via the Odin method from this forum. Everything was great until today...
I do not think this problem is related to the rom, because it happend before in HC 3.2 BEFORE I even rooted the tab.
Also, the problem persists even when the tab is "off" as you can see the corrupted charging screen. Recovery and download modes also show the corruption.
Has anyone experienced a similar problem? What can be done (the tab is out of warrant).
I attached photos of the tab exhibiting the problem.
Thanks for your time!
If you search the forum, you'll find that a few others had the same issue. If I remember correctly, they had to send it to Samsung, as it is a hardware issue.

hi
can anyone please help me?
i have had an atrix for almost a year now and have had no issues with it. recently i took a big step and decided to get the cm10 rom by th3bill onto my atrix!
all worked fine for a few weeks until about a week ago. i noticed that my lockscreen pattern wasnt entering as normal. the pattern would not connect to the dots i wanted it to. on the main screen if i tap on the central button to get to the menu for my apps it will automatically respond my touch to the right/left icon and take me onto my contacts/sms instead. also while typing certain letters e.g "t" will not be recognised and instead "r" will show up instead.
somehow i managed to remove my pattern lock but the other issues are still present.
i thought that it may be a bug with the rom so i decided to go back to cm7.2 which was running perfectly on the phone thinking that this may be the solution, but even that rom is now giving me the same problem :crying:
can someone please advise me as to what the problem is/what i should do?
thnx in advance
Ok so i also had/have this problem. You can find a temporary solution and info here http://forum.xda-developers.com/showpost.php?p=27595402&postcount=1
I replaced my digitizer and the dead zone changed position.So know that replacing the digitizer might help or might not help...
Good luck

[Q] Touch screen decalibrated. Not hardware issue
Hi everybody! I own a cellphone Sesonn C2000 (mt6582), and like all cheap chinese phones, it has no support at all, so I'm very frustrated with this problem. My problem is that after a failed try to flash a custom recovery for it, using SP flash tools, touch screen didn't respond, and after a while began to respond but touches were very decalibrated. At principle, I thought it was a hardware issue, so I tried all advices about it: knocking gently the screen, putting cell phone into freezer, long pressing power button, and nothing of that worked (and now thinking, lucky me that cell phone didn't break by those actions) At the end, I decided to open it and watch by myself if it was something bad inside, but all was ok at sight. I also could see that the touchscreen's IC, is a goodix gt915. But what convinced me that issue wasn't a hardware issue, was that I tried, to flash another rom, that in another similar phone caused a similar issue, and touches changed their behavior as a I expected. I don't know much about it but i've read, that problem happens by flashing a wrong kernel (kernel inside a recovery or system. img), and by wrong kernel, I mean a kernel with a bad embedded touchscreen configuration. Correct me if I'm wrong. Anyway! I've tried touch recalibrate app, tscalibration2, htc calibration, touch screen calibration, none of them worked; I've tried many proposed adb batch files to fix that problem, tried to reconfigure tpd_def_calmat file, and nothing. Even I'm exploring an app called gtp adb tool from goodix company, but despite I've translated to english all what exe lets to translate, still left many items on chinese (I used resource hacker, and all that it let me to change, I translated it) and, not being enough all that, there are too much technical items on it, and its manual, oh surprise: It's in chinese! ... Anyway!
Going to the point, I understand that must be a misconfiguration of the touchscreen, so, how must I reconfigure it? or if you see I'm totally lost on my search ¿what can I do to recover my touch screen? beforehand thanks whom can help me.
PS1: Fortunately, more knowing it's a cheap one, this phone has OTG support, so I still can control it, but I miss its touch function so please help me.
PS2: Apologize me any fault on my english. I'm a spanish speaker.
