XDA Mini (Wizard Screen Issue)

My XDA Mini has a screen issue.
Only part for the screen (the middle) has stopped responding to the touch pad.
How do I fix this, has anyone else had it?
Cheers
Max

My Wizard (O2 XDA Mini S) has just developed this problem. The touch screen does not respond to touches around the middle of the screen. The outside edges of the screen work fine however.
I've had it for about 4 years now though, so I suppose its lasted well really. It's a G4 and I installed a WM6.1 ROM on it about 6 months ago (which is awesome btw, makes the phone sooo much better / faster!) but I don't think this is related to the problem.
Any known fix for this? I think it's a hardware issue since I also have the problem where upon opening/closing the keyboard, the screen goes white with multicoloured vertical lines and the phone emits a high pitched noise (have to put phone into standby then wake it up again to resolve). This, whilst annoying, I can live with, but not now the middle of the screen no longer responds to touches
I read somewhere its to do with the ribbon cable that connects the screen and main board, its gets trapped or worn over time as the keyboard is slid in and out. So I guess the touch problem is a more severe symptom of this? Can it be fixed?
Also a point of interest is that I keep the phone in the case a lot of the time. Could the magnets have possibly affected the screen? Anyone else with this problem keep the phone in its case a lot?
Thanks in advance,
Jamie

Touchscreen not responsive unless left softkey is constantly pressed

Hey guys!
I've seen people complain about broken Wizard LCD/touchscreen around here but none of them said anything about partially functioning touchscreen. So here it goes:
A few days ago my phone stopped responding to taps. Just like that! I updated the phone with the latest ROM from HTC (official) and no change. Since then I've been lurking this forum trying to find something similar ...
I've flashed it with custom roms, now I'm trying the WM6 with the hope that maybe the touchscreen will respond to taps by itself, without me having to keep the left softkey pressed while tapping. I can't decide if this is a hardware or a software issue.
If anyone should have any idea about this, please advise. I'm not afraid to open it up or anything like that...
ps: waiting on a replacement touchscreen I ordered off of eBay. ($12)
Thanks a bunch,
kevin

Same Problem
My touchscreen has been acting up lately and today it just stopped working. Tried many things like you with no luck. However I followed your advice on pressing the left soft key and the touch screen started working.
Does anyone have any clues?

touch screen prob.
if your touch screen is not responding then you have to chang the touch screen if it responce some where in time then you open you device and just resolder the touch screen film connector (back side of screen)its just get drysoldered thats why these things happen like you press rite side of screen and it geting work again if relese its stop working................
you have to do only re sloder the connector of touchscreen

Different Problem
Like the post originator said, the screen does work, you just have to hold the left soft key down while tapping. Also did take it apart and didn't see any problems.

Mine just developed this issue, anyone have a fix? I've got a digitizer (Touch panel) on order from ebay as a 1st step. Anyone have any other ideas?
Thanks!

Ok this is odd, but I'm suddenly having the same issue. Touchscreen doesn't work unless I'm holding the left soft key as well... This has to be software right? Anyone have any ideas yet?

I dont have this problem.. but this is 'interesting' I'm wondering, if it is hardware or software problem. For hardware problem, you can try pressing on the area around the left softkey rather than the left softkey. For hardware, you can check to see if it is working after a hardreset?

This issue has to be related to corrupted software that was installed, I mean how can this many people have the same exact problem around the same time if it's hardware related. Compare notes: All those having this issue,submit the most recent software that was installed, and if everyone installed the same thing, then that's the culprit!

Touch Screen Not working.. plz help.

Hi mates yesterday i bought a used herm...with excellent condition. but when i opened any dialog. the window closed automatically. and the screen light remains always on. and touch is creating problems.
and after some time the touch screen totally stop working. i dont know what happened. al the buttons are working fine. i upgraded my t-mobile herm to its original t-mobile wm6 rom. and again the touch screen is not working. and the screen light always stay on..
so is this hardware or software problem.?
guide me if you have any clue about this..
according to my thinking.. i think some button is pressed continuesly.. but everything is working fine.. only the touch is not working.

broken digitizer for the touch screen, buy a replacement lcd/digitizer together and replace yourself, about $100Aud. Use Mike Channons site to download the service manual. Use the search function and type in "htc service manual hermes".
As for the light, you will have to use your buttons to navigate to settings>system>backlight>battery power and external power. you can select how long the backlight remains on for.
Cheers...

Hi mate thanks for your reply.. Actually the situation is that. the screen is working perfectly. all buttons are also working perfectly. but suddenly the touch feature stopped working.
that time i was just opening some menus and they closed automatically. it looks like that there is some button pressed. and the screen light never stops. it continuously remains on. all buttons are working perfectly and everything. on the touch feature is not working.
i upgraded my device with genuine shipped t-mobile wm6 rom and again it stopped at the starting screen where i have to click the screen and the device brings the window for stylus adjustment.
so i wanna ask that is this also possible that some touch drivers are corrupted or something like this.? or is this a hardware failure.?
Kind Regards

I had same problem, it was hardware. Thats why I said to change the lcd. It is theoretically possible to replace JUST the digitizer, BUT, it is a MAJOR hassle.
As for getting past the alignment stage, look up Remote Screen Alignment. Its a cab file that stores the alignment settings on your pc. You WILL have to have a friend that has the same phone so you can get their settings as you need to copy them to your pc first. You can then copy the settings to your phone so you can use it until you replace that pesky lcd...
Cheers.....

I had a similar problem with my hermes. After a lot of investigating, I found out that this is a heat related issue with the hermes. The unit will heat up an some connection somwhere gets messed up and continually registers ghost taps on the upper right corner of the screen, which causes the continual opening and closing of programs/task manager. This overloads the phone which then causes the screen to eventually become unresponsive due to excessive computing.
With my phone, it must be heat related because it will only occur during or after heavy use or overcharging. Other people have had this exact problem with the conclusion being overheating. The worse part is, there is apparently no way to fix this, replacing the screen doesn't change anything. setting your screen alignment very far left will fix the problem but then everything you tap needs to be compensated for.
Good luck, hate to be the harbinger of bad news, but it's better to know whats wrong and that you can't fix it then not know whats wrong and keep trying to fix it.

same problem here... only my hermes is overheating already after 5 minutes use...
in the morning it works and when i put it in front of the airconditioning the touchscreen also works...
somebody who has an idea where to look for a solution??

Some of the suggestions in the white screen thread/s might help. The problem is that those who have the heat related problem will find it very difficult to trace the actual fault. The heat may be causing miniscule expansions on the boards / components and connectors. The tiniest of cracks or poor connections can therefore break with the expansion.
Another theory is that rather than heat it might be a capacitor that is breaking down either over time or again through heating. Unless you are a skilled electronic engineer that is virtually impossible to check, particularly since schematics are not available.
You might just be lucky if you dismantled and re-assembled - it might just re-set a connector or adjust a board so it does not get affected in future. That would be very much a matter of luck and of course potentially the situation might be made worse!

Hi mates. I am back with some issue.. i moved my device to a repair center and he said that its a software issue. and he fixed my device without changing any rom.. i dont know how..
but again when i open some window like programs. the right scrollbar make a problem... when i move scrollbar it automatically press the top close button..i aligned my screen 3 times but same problem with right side scroll bar.
and after playing with it. the touch totally stopped.
now the thing is.all the buttons are working fine and everything is working fine. even sms and calls. but when i check sms and press my scroller button. it displays the right click menu instead of opening the sms. and the screen light is continuesly on. as something is pressed. so. i think this thing wil help. i am now trying this method to check my pc.

check this out as well.
i will send you details soon.

might just have something lodged between the case and screen.. also to get rid of the screen alignment, cable it up and delete welcome from the startup programs and then reset it.. should get you past it so at least you can use it until you repair your screen

HD2 oudside in the cold.

I tested out the HD2 outside in below freezing temps, and it really had a tough time registering my finger presses. It took about 5 minutes, before it could register properly... Anyone experience these issues?

Yes, and the wind keeps pressing things which makes it almost useless. I'm hoping some of the hints here on how to make it less sensitive will help but I haven't tried it yet.

I've noticed the "ghost" pressing (the screen registered a LOT of presses when my fingers were nowhere near the screen) of the screen too. I also contacted HTC support on the issue, and they said it was not a known problem.
So, again, I'd suggest that if you're experiencing issues with the screen in cold temperatures (finger touches not registering, "ghost pressing" etc.), let HTC know about it!

i got that kind of ghost typing too. pretty funny to watch but annoying when you see its deleting mails, answering sms or calls people ... will contact htc as well to let them know.

Confirmed here too. Though I thought it was caused by constant rain/snow here in Moscow, which fell directly on the screen when the ghost tapping occured.

Yeah I get the ghost tapping but only after i've been in a call and hang up, it then starts doing all sorts of things by itself normally ending up with dialling someone!! :/

I dunno about the ghost-typing but isn't it a common fact that capacitive screens don't work well with low temperatures?

That's a capacitive touch-panel "Feature" . HTC can't do anything about it (besides lowering the screen sensitivity).
edit: Umiss beat me to it lol

you can lower the screen sensitivity either by installing the new 1.48 rom or using the cab from the hints and tweaks thread in opening couple of posts. Should help.

[Q] in call bug, help needed

I have a really annoying bug in my WP7 HD2. When i make a call, the screen goes black and i cannot access anything. The call connects fine but the whole phone locks up. I can't access the dial pad for using automated services, nor can i hang up. Hardware buttons do not work either, but light up briefly if i push one. I think its something to do with the light sensor, sometimes if i cover it and uncover, the screen quickly comes on then goes off again. Any ideas? I am using the latest radio from the stock HTC WM 6.5 ROM, and the newer (51t?) radio for WP7. I have tried older versions of both, and a few different WP7 roms all with the same problems.
WP7 Mango (xboxmod/yuki)
UK HTC HD2
This problem also happens on android.

Uhh, sounds awful 'cause you experience also on different Android...
Do you experience this also on a Stock WM 6.5 Rom (of course with the original radio and without hpsl)? If not, you can be relaxed cause it's no hardware fault then. If it's also present on WM 6.5, then it's very likely to be an hardware error.

a little update on my problem. it appears that if i tilt the phone at a 30 degree angle downwards, while in a call, the light sensor functions normally. so at least navigating those phone menues can be done! i think this is a hardware problem, my HD2 did suffer a pretty nasty fall (which resulted in a new screen!) so maybe there was some other damage beside the screen.

there are two sensors together to the left of the earphone at the top of the screen, one is a light sensor, the other a proximity sensor. It seems to be the proximity sensor that is at fault. When you put your ear to phone it switches screen off so you dont push buttons.
I have read that the prox sensor can become misaligned when replacing screen. Did it occur after this? warranty?

as soon as i make a call the screen switches off. also the auto brightness doesnt seem to be very responsive. the issue had happened before but it was more of a driver issue than a hardware fault. i noticed it more after the repair, but it was not instant. maybe one of the sensors was lose and after a few months of use it is now misaligned? the phone is out of warrenty, and the 3 month warrenty on the repair is also up, and i have no insurance anymore i am holding out for a new phone. just started a new job so hopefully i can get something outright without being tied to a contract

Same problem
I'm having the same problem I think I noticed it when it was running windows 6.5 but I really noticed it after 7 upgrade. as soon as I make a call I cant access anything. THe bad thing about it is this phone is a replacement. I just got it. Maybe they sent me a badly refurbished one. Has anyone found a solution to this. If i'm smart I know this is not as simple as changing a setting sound like re flash, erasing, re installing, etc.

did you try tilting the phone downwards towards you? when i do this the menu appears and i can access everything. normally i put it on speaker then the screen stays lit then i cna use it as normal
