MDA Pro running Qtek-rom > weird green distortion on scre

Hi there,
Thanks to all you ppl on the forum i managed to upgrade my brand new MDA Pro with UNI_QTEK_WWE_13077_130176_10900_WWE_Ship.exe as found on the ftp.
Speed seems better, and i like MSN....
Yesterday i noticed some green jittery lines along the righthand side of the screen (LS-mode). When i flip the screen to Portrait mode it stays in the same spot (then it's along the bottomside).
Looks like this:
. . . . . . . .
- - - - - - - - - -
------------------
_____________
It's moving, and seems to be active when i touch the screen or when the device is 'thinking'..
Anybody know what this is / how i can fix this?
I already tried searching the forum for 'green+screen' and 'weird' but nothing usefull turned up
Thanks in advance!!

Seems to get worse
When i try to play a video (TCPMP) it seems to get worse and the jittering goes like mad. It stays in a particulair portion of the screen (bottom in portrait) and takes up the space of about 2 startbars stacked on top of each other.
They look a little like status bars of some sort, anywauy, i don't want 'em :x
Please don't tell me to do another upgrade.. would be my 4th in 4 days, and it takes about 3 hrs to get it right (with installing all apps and settings etc). I noticed that spb backup doesn't like it when i try to restore my settings into another ROM than it was made in.. but that's not my actual problem >> green lines from hell IS
Thanks for your time,

This looks like a HARDWARE problem. I get these in my PC before when the video card was on the fritz.
Anyway, if you don't want to hard reset, i cannot help you.
If you do hard reset and the same problem is still there before installing ANYTHING, then it would probably be HARDWARE unless you re-flash the QTEK rom....

Whaaat?? Just got the D*MN thing 4 days ago, treated it as a newborn child...
Anyway, i tried the 2 softbutton reset, same, tried the power/lightbutton reset, same, tried ClearStorage, same... Should i install another ROM perhaps.. any suggestions?
I noticed the weirdness showing up at the bootscreen (with Qtek logo), then comes the windows logo, which seems to be clean, and then pin-code-screen has it again.
Jorgee it indeed reminds me of faulty videocards on my PC.. aahhh noo, not again :shock:
plz advize
regards,
murc

yup.. probably hardware
hi.. well, installed UNI_TMUK_12032_120_10600_Ship.exe, same thing.. guess i'll have to take it to the local t-mobile shop and see if can get it replaced under guarantee...
Weird stuff though, never dropped it, bumped it, could it have something to do with ROM upgrading?

Make sure you flash it back to the correct ROM before returning it. hehehe
Maybe someone at the store twisted the screen MORE THAN 180º (someone like the sales person) then stuffed it back in the box and turned a bind eye.

Screen Issues

Hello All,
Since installing WM6 I have been having some strange screen issues. I suspect it is just coincidence. I have installed various different roms and I am having the same trouble ( currently latest lvsw ), making me think it's probably actually a hardware issue.
The screen behaves as if the top right corner is being pressed. This closes apps in portrait and brings up the start menu in landscape. It doesn't happen all the time, but doesn't stop once it's started.
Has anyone heard of this? Is this the same problem as the alignment issue? I have tried the buisness card fix to no avail. Should I take the phone apart as described in one of the fixes for alignement or do I need to send the phone off?
Yours hopefully...

How old is your phone? Some models had screen alignment issues which could explain your problem. Have a look at this thread and see if your serial no (HTxxx) fits with those with known problems. If it does, read Mrvanx's guide to put your phone ROM/SPL etc back to original status then send it in for warranty.

Mine is a HT648 which doesn't have any known problems with screen alignment. I have moved to canada, so although I am still in contract with vodafone, it is very difficult to send it back for repair. It will be my fifth replacement if I do!!! All previous ones had the screen alignment issue, this one is at least slightly different.
I am tempted to try the dismantling fix described in one of the other threads, but perhaps I should ship it back to the uk for a friend to hand in to vodafone for repair and then have it shipped back over here...

If you open it you void your warranty. If it is the screen alignment issue and you fix it, then you are good. If you open it and it is not the screen alignment issue then you just voided your warranty and cannot get it readily fixed. I had an earlier TYTN and I had the screen alignment problem pretty bad. I opened it and fixed it. It was pretty easy.
I would probably try to install a different ROM and and see if it still happens.
Good luck.

I've tried lots of Roms, unfortunately that hasn't fixed it. Reflashing back to voda and sending back seems sensible, but I'm not sure I have that much pacience!

i did the business card technique. use a business card around the edges and take out some of the black brittle gasket. make sure you keep it real clean around the edges.
I used a microfiber cloth to get under there with some lens cleaner. I read on another screen alighnment post to put a small piece of business card under the lip of the lower portion of the screen(that probably doesn't make sense but do a search for screen alignment).
when you slide out the keyboard i loosened those screws a quarter turn. someone also made a mortscript for screenalignment that helped as well,

Hi !
I have the same problems with the same ht648. The problem occured step by step. First after upgrading to WM6 everything works fine. But since 25th my device starts problems with the touchsceen so I can tap on it everywhere without response. I think it is a thermical problem, because when I put it into the FRIDGE the touchscreen works again for a while.

Have same problem here i also have a v1605 HT648 and i have had it for a month now. It has worked well till yesterday when it started exhibiting this problem. I haven't done any ROM upgrade or anything.
This is really a pain - i hope i can get it replaced

GHOST IMAGE [Rom bug, or hardware issue, please have a look?]

Guys, I'm noticing i'm having this problem, where by the bottom bar for the windows today screen, is appearing everywhere, especially during volume adjust.
For example, i click volume button, it will bring me to the volume screen right? if i look very very carefully at the bottom, i can see a very opaque image of the bottom bar, even sometimes with the words "calendar" and "contacts" visible! a soft reset immediately solves this, but after a while the problem comes up again.
I've tried the following roms
Aztor
Dutty
Diamond rom
Swift SBL
all with this same issue. Is it a bug, or is it a hardware problem? I tried taking a screenshot and the screenshot does not show the opaque "ghost like" bottom bar with the words calendar and contacts.
I tried switching off Touch Flo 3D, and sometimes after a while, it appears again. It can be best seen when the screen is black (not off, just black) especially when volume adjusting.
Is it just me, hardware problem screen problem, or a rom bug that everyone has?

just to clarify again, despite it being visible to my eyes, SPB screenshot does not show this "ghost like" image, and it looks perfectly fine in the screenshot

I dont see that but I think it can be a sort of 'memory' thing of the lcd-screen.

Same problem here
Hi!
I have the same problem here...
the Ghosting comes after using the phone a lot so I think it might be because the phone heats up.
All the roms I tried have the problem so I think its an hardware issue.
Just keep your screen off for a while (not the phone) and I think it goes away.
Also TF3D has nothing to do with it...The problem happens with or without it on.
If anyone has a soln I'd love to hear it!

great to see that i'm not the only one. was worried sick that it was a hardware problem

Hi Baronic i've nothis more than a month back... see this thread..
http://forum.xda-developers.com/showthread.php?t=417629
also see this thread...
http://forum.xda-developers.com/showthread.php?t=420644
So you or me r not alone..
I used to be worried whether over next few days or weeks whether my screen will get worst, hence i used to keep screen very low brightness (with Spb shell)..
Over last 4-5weeks atleast there is no progress of the screen problem although it still persists..
Not finding a final answer, i've stopped bothering about it and just enjoy my diamond..
U r a senior member so, If u find an answer please dont forget to PM me..

Forgot to mention a tip... Keep brightness lowest and you'll never see it again.. (Although i like my screen to be brightly lit!!)

oh i didnt see those threads. primarily cuz i didnt know wat term to search for lol. if its a memory problem i think it can be fixed. will try and see how it goes, i'll experiment

hardware problem?

hi, had my desire z about a year now, since ive had it, quite rarely ive had a problem of it seeming to have a mind of its own, for example, icons may be selected, or the home screen will slide accross by itself etc. ive always put this down to a trackpad problem.
the other day (after having a miui rom installed for about 2-3 weeks, which was fine untill now), it started acting up strangely, the above problem started happening, but more severe, also the touch screen and softkey buttons would stop working for periods of time (or stop completely untill reset), but screen rotation etc would still be working, which shows that the O/S has not frose and is still working behind the scenes (making me think its a hardware problem).
now, i think ive worked out that this seems to be triggered (mostly) when i open the keyboard. (as also, when the touchscreen stops working etc, sometimes, sliding the keyboard open and close several times, will sometimes seem to unfreeze the touchscreen etc, and will be back to normal, for a while). ive tried doing full wipe and reflashing etc, but i still have the same problems mainly when using the slide out keyboard, which again, makes me think its hardware (possibly keyboard ribbon cable?)
i really dont want to send it off as that means getting it all back to stock etc, and last time i needed the screen replaced, took 6 weeks to get it back!
if anyone could pinpoint the likely source of the problem, id rather replace the part myself..
would anyone have any ideas, as they would be very much appriciated... Thanks...

anyone at all?

I got 2 Zs meanwhile but dont have any problem with the keyboard.
But sometimes when its charging i got the same issues like you - no touch is working and the screens are sliding nearly automatically.
I think this has nothing to do with the keyboard...
Hope this had helped you a bit

thanks for the reply, unfortunately im still no closer to finding source of the problem, its intermittant, happened lots yesterday, not so much today, maybe the digitiser? its like there is another invisible finger touching the screen..

This would happen when i was on stock froyo, like it would cause the home screen to hang, but if i was ion an app it worked fine. I would use it to refresh of sorts when my phone was hung up or i need to reload my apps from sd lol. Sounds weird I know, but even with stock froyo i had problems with my keyboard but with the prerooted GB its as smooth as butter...

still going on, and getting more frequent, i dont think it is to do with the keyboard anymore. im now guessing it is the digitizer, its like someone is pressing an invisible finger on the screen, roughly in the center. it comes and goes, it happens for about 3 days, then goes away for a couple of days etc.
also there is very little info anywhere on the net that can help, including replaceing the digitizer itself
anyone ever replaced one on a disire z/g2?

[Q] Touch sensitivity issue cause?

I've been reading through the previous threads and I'm still confused if the issue is hardware or software related. I have the AUO panel and have broken swipes, and times where I can't scroll properly. This has been going on a couple months now and it's getting on my last nerve since it's frequently happening when I need my phone to work properly. All this time I assumed it was software but a couple threads mentioned it was hardware. Trouble is, some people with the JDI screen also have issues so I don't understand. My question is, has anyone ruled out software by flashing an AOSP rom? I'd rather not send this to Sony if at all possible since they don't cross ship and I'd be without a phone.

I have rarely an issue with the touch screen, when swipe up or down, it doesn't swipe it acts like I've just touched (clicked) once the display. I think it is a software issue, because in my case, if I turn off the display wait for 2-3 seconds and turn it on, it works with no problems.
Can you point me please to other threads that have this issue in discuss?
Thank you!

Have you removed the asf from the screen and placed an actual screen protector on it? I found that this really helped with the weird screen issues.

I have a screen protector over the ASF. But that has nothing to do with my issue, because, like I said, when I turn the display off, wait 3 seconds, and on again everything is working normally.

Yeah, I reboot usually and the issue temporarily goes away. Then it will come back a day or two later. I'm afraid to remove the ASF because I've read some issues with goes touches even with a screen protector. I just want the issue to be fixed... I was thinking of flashing a AOSP rom but wanted to see if anyone with that ROM had any trouble or not. Maybe the L update in January will fix things.
Here are the resources I've read on this issue:

http://forum.xda-developers.com/showthread.php?t=2770293

I have rarely that issue, like I said I just turn off the screen, and after 2-3 seconds turn it on and it's gone. I'm sure this is a software related issue.

If it helps at all, I never had the issue in the two weeks I tried an aosp rom. However the camera and battery life were a bit lacking so I'm back on a stock rom.

I haven't have the issue too in the past weeks, I've wiping cache and dalvik cache pretty often , because I've installed some system apps. Anyway I will really want to know the cause of this
L.E. I'm still on stock firmware.
L.E. 2 : The Glove mode function, in the Settings-Display menu has an application or something? Has a file redirected to it? Is there in the phone's system a file than can be edited or deleted or something for the glove mode function? Maybe we will find answers there.
I'm not sure that I've made myself understood with the question.
