Problem with screen

I have a problem with the screen on my wizard...
When I close the screen, the characters appear with wriggly lines in them, as if they are breaking. If I slide the screen open, even just a little, the characters are stable.
Any ideas?

It seems more like a Hardware fault the software,but no harm confirming.The 'Digitizer' of the Lcd is faking out or connection problem of the connectors,did you disassemble the device recently or something for repairs,or did it fell on the ground and got damaged.
Which OS version Rom your are using,if you have upgraded to any custom Rom,may be,I don't think so,but might be there's a chance,reflash the Rom again and check if it helps.
cheers

I flashed the rom & reinstalled the OS, but still the same problem. So it looks like a hardware problem.
Probably some connector cable or something.
Are these difficult to open, or should I take it somewere to get it fixed?

Well, if it's still under warranty,then I'll suggest you contact the vendor from whome you got it and let them fix it,otherwise,if you got any experience and knowledge of disassembling and repairing it,then download the service manual from the vendors website or from the xda-forum wiki and try out.Otherwise consult a repair shop.
Cheers

Well, I got a manual for the wizard, openned it up, tightenned all the connectors & cables, and now it works like a charm!!
Thanks for the replies.

is this the correct hardware device?
thanks for the help

I guess its right, i never tried or bought it from eBay but by the pic and description it looks all right but dont go on my advice wait for other to post too.

I would suggest that you dismantle your wizard first and check the ribbon cable on your phone matches yours
I have replaced the digitizer on my old wizard before and found that there was 2 different digitizers, each had a slightly different ribbon cable. The first didnt work at all but the second worked perfectly. Also i noticed that on both digitizers the strips on the cables didnt align properly with the board, however it was still possible to solder.
Make sure you have a soldering iron with a very fine point, its very figity to replace.

Thanks.
yes I will do it first. My problem was to understand if this is the hardware component that makes the lost of align issue.
Nowadays we have to open the keyboard to recover the align values.
Thanks to all

Thats a very weird problem, it may be software related, a bug in the OS maybe?
If that is the case then backing up your phone then flashing with a rom of your choice may fix the problem (i would try that first before replacing hardware)
Personaly i would suggest the brightphone rom its clean and very fast, however you have to identify wether your phone is a g3 or a g4 and get the right rom. all in the upgrading guides

Make a search and you will find lots of posts with this problem.
It was present sincd the wm5, wm6, wm6.1, etc.
So, it's really hardware.... unhappily

Digitizer replacement?

The warranty for my HD is gone and I would probably need to change the touch screen digitizer myself, found these on ebay for ~60€, but does anyone know how to change them? Again, any help would be appreciated!
Originally:
HTC Touch HD, it has been a wonderful phone until now. I have encountered a wierd problem with the touchscreen.
First the touchscreen stopped working completely, after awhile it suddenly started working, at first it recognized some bits and pieces but now it recognizes every touch as normal, except..
It is very inaccurate and the "sum of inaccurity" seems to change depending on where I push the screen, the screen alignment option in settings does not fix this.
I recorded two videos to show this problem better:

Any help would be appreciated on how to fix this!

I have handled it with great care so no big knocks or drops. Ill contact the store about the warranty. Just wondered if theres a way how to simply fix this.
Just noticed, the screen works normally sometimes for one touch, then it goes back to the inaccurate **** :/
Im now guessing that some cable could be loose or something like that?

Have u tried recalibrating the screen? I can't remember exactly where I found it, but its in programs or settings somewhere.

Anyway I RMA'd it now. Hope I get a new one

I can tell you from previous experience, HTC does NOT warranty touch screens. You mentioned "a store", so I hope they help you, because HTC will not. >sigh<

Seems a little unfair if they don't seeing as the HD is purely touch screen!

Hmmh, well the store probably sends it to some service center here in Finland that fixes HTC phones.
Indeed sounds very stupid if the warranty doesnt cover the touchscreen.
Perhaps my HD suffered from something else than a broken touchscreen, eg. mainboard or a chip that controls the touch screen. Who knows I'm just hoping it "passes" the warranty :|

Well... Had Hard-SPL on my touch hd and duttys 1.7 rom, so the warranty is gone
Didn't know they were so picky about it, they said it would cost 605€ to repair the screen. So now I should probably start looking for a screen digitizer on ebay and some help on how to change it... Already downloaded the service manual, but there was nothing on how to change the digitizer, could anyone here show me some light to this? Thanks.

I have dismantle my HD to see if there's any way to change only the screen (it's broken)
There's no way, as far as I saw. You have to replace LCD, tourch screen and screen. It's one piece and there's no way easy way to open it without break it.
You can find all of them for about 200E.

Another sad story // hopefully with a good ending
I kinda have the same problem as Viba and others. Sorry for the looong post. But decided to describe in more details my experience up to now, and hope you can help as well.
All of a sudden, I started having problems with the touch screen of the Touch HD. I started noticing that whenever I touched the Touchflo buttons, the phone vibrated. Soon I came to realize the if I touched in some spot, the phone recognized that I was touching lower, to the point that it could not recognize touches in the taskbar, for instance.
The united has 2 or 3 months max. It had some falls before and I do not really know who (or which one) was the culprit.
Tried this as fix: re-alignment, hardresets, Official ROM upgrade. Then I started reading and understanding that the problem was probably the digitizer ("nice to meet you").
I live in Brazil and the Touch HD is not expected be released here any time soon. So the few HTC service centers do not know how to fix it and do not have parts for it. And also, I bought mine from an auction site by some user who bought it abroad, with no warranty whatsoever. I am left alone in this.
I was very frustrated and eager to get my device running again. So I started looking for a new digitizer and also the tools to open my phone. The digitizer (just the digitizer, not the LCD screen) I ordered from an ebay shop in Hong Kong on Monday and is expected to still arrive sometime in this century (IF Brazilian port authorities do not mess up). The tools arrived yesterday.
I downloaded the service manual and said to myself, let's see if the digitizer problem is maybe due to a loose flat cable. Got to work and carefully disassembled the device as per the service manual. (I have to say that, although I try to be carefull, I always scratch, bend or mess something up when I do jobs like these. So I was afraid of cracking some plastic or worse and actually did some.)
Up to where the service manual show, it went incredibly very well. But that's the problem. The service manual guides you to disassemble the unit up to the point where you are with the bezel, LCD and digitizer in one piece.
But hey! I saw zillions of internet shops selling the bezel (actually, the hole housing, but with no LCD), the digitizer or other parts separately! What is going on?
So I started trying to unmount the bezel, LCD and digitizer. Tried several things. It got really late. I was impactient. So I tried splitting the digitizer from the LCD, by inserting a hard plastic aluminium tip between the digitizer and the housing. A very thin plastic kind of tape came out (at lest part of it). So I tried doing it more. No success. And then I put a very thin screwdriver between then (just enough to get an ulgy bent it the plastic housing).
When I had played enough with that puzzle, I gave up and began mounting everything back. The good part is that I was able to get everything back and the phone is working. Well, except for the digitizer.
First thing I did was to kidnap the wife's Nokia E71 I bought her last month and she is not using yet (she couldn't learn to use yet; well, she hasn't even tried it), because I have to have mobile access to my emails.
And I really started now to consider other alternatives. Will some user like me EVER be able to change just the digitizer? Is it even possible? If it is, I would like to give it at least another shot.
But I am also afraid that it could be another part which is in failure. I just don't want to spend more $$$$ in this. It would be better to buy another phone (and maybe not a complete touchscreen - gosh, I miss my Tytn II). I so regret being a gadget freak and not waiting a release in my country.
Shoud I send my phone abroad for a service center repair? My sister lives in Dubai and she may be able to help.
Should I give up my unit and seel the used parts in ebay?
Hope to hear your suggestions. Thanks anyway.

before doing this what about removing hspl and reflashing back a stock rom
change shop and you might, and i say MIGHT, be lucky
much better than screwing up the machine

Nice to know I'm not alone with this problem
Sucks that the digitizer couldn't be removed separately, would help alot if someone knew how to do this, if even possible..

I have already tried with 3 custom roms and 2 original SPL:s with two original roms.
The Finnish law allows me to get my HD replaced if I could prove that the custom rom didn't brake the digitizer. Already sent some emails to the local repairstation for HTC phones here in Finland, lets see...

I run a repair center (US). I have not gotten curious enough to take mine apart, but if someone has a dead one to experiment with, PM me.

Broken digitizer glass
I have the same problem with the digitizer glass being broken. I have had the back off the phone and stripped it back as far as I dare, but the service manual just doesn't tell you how to replace the digitizer and glass only. Checked out youtube where there are many videos with instructions on how to replace the screens and digitizers on lots of different phones as well as the iphone, just nothing on the Blackstone yet.
Any one else found a solution or decent instructions?

Today I disassembled my HD too, found a loose screen wire but nothing else. Even when I attached it properly the screen didn't work.
Has anyone found out how to change the digitizer?

some info
Hello,
I am also have HTC Touch HD, and I am also thinking about replacement of touch screen and housing because of scratches. Here instruction in Russian
http://www.pdacenter.ru/razborka/htc-touch-hd/
step 24 is not shown on the picture, but there is mentioned that in order to replace screen you should push it forward from back side of the screen; also mentioned that screen is fixed with double sided tape (probably it is fixed to the touch screen)
Also, did you try to use any polish to remove minor scratches on the touch screen? HTC Touch HS has resistive screen and probably may be polished (in contrast to capacitive touch screen that has some coating).
All the best

Also, about this problem see
http://forum.xda-developers.com/showthread.php?p=3911326

You guys should be smarter! If you want to warranty exchange it, flash the normal SPL again and flash a stock rom!

htc hero(gsm) digitizer replacements don't work( 2 replacements )

so I got the first one, installed it, didn't work... put the old(cracked) one back in... works perfectly just has crackes all over the screen wich bother me...
I contacted the seller he said I could get a refund or a new one instead. I told him to send me a new one.
so the second one has the same problem, it just doesn't respond to touch...
booting in HBOOT mode I can see at the top that it recognizes the touch panel as(TOUCH-PANEL-SYN0104) same as the old one(I tested all three digitizers to be sure..)
so am I doing something wrong? I figured if the digitizer would be broken, It wouldn't be recognized by the HBOOT menu, like when I don't connect it at all it says: TOUCH-PANEL: fail.
I'm a developer so I really need this phone to work because the emulator is really laggish and slow, also I can't afford another phone so please if you have any experience with these things... help me out.
thanks!

Why dont you just ask the seller to fix it for u?

Maybe there is a wrong connection to the ground
As far as I know, the digitizer needs some kind of link to the ground that can be deficient in the two replacements you tried.
I don't know much about it, so it is just a assumption....

[Q] Touch screen doesn't work...now what?

I dropped my phone and cracked the screen. So since I've did that, the touch screen doesn't work. I went to get the screened replaced and went to test it out and it still doesn't work. What's not allowing my touch screen to work after getting the screen replaced? If I change the screen does is the digitizer attached to the screen so therefore it will get changed too or is it a separate hardware?

Most likely faulty replacement part.

Try downgrade to 4.2.2

Hi, I've purchased a cheap diplay at ebay. Touch didnt work any more.. after a number of tests i found out this was due to a HW test at boot. When downgrading 4.2.2 everything works fine. Any upgrade 4.3+ failed to enable digitizer after reboot.
PS: When booting eg 4.4.4 with the old digitizer connected and then connect the new digitizer w/o rebboting the the touch was working well.. I'm very interested in geting a confirmation or reason what causes this issue kindly keep me posted

Most replacement screens use an original LCD (recycled from a cracked screen) fitted with a copy touchscreen. Either the incompatibility could be deliberate on LGs part but I think it's probably due to a driver update or something which has broken compatibility with the reverse engineered touchscreen. It could also be a coincidence, some copy parts are prone to just not working for no real reason sometimes.

Hey DrFredPhD
Can you imagine a costum rom with the old touchscreen drivers from 4.2.2 into 4.4.4?
What would this require: To compile a costum kernel? The drivers would usually be in compiled form in the boot.img, right?
I've tried to flash 4.4.4 with the old boot.img from 4.2.2. - but the phone didn't start (as expected..)
Can you imagine someone how could help me in this regard? I think there may be a number of people facing the same problem..
Anyway, thanks for your help - Greetings :good:

Binaries are available for nexus 4, maybe compiling from AOSP with older binaries would work, but you might break functionality too.
It's been done on other devices but probably not for the reason you want.
https://developers.google.com/android/nexus/drivers#makojdq39

So what are you essentially saying? Put the mb in a good working nexus and see if it works or that maybe the tech put a new digitizer with the old rom driver onto an older mb with a new rom driver? And that could possibly cause conflict with drivers or roms? Which in turn will not allow my screen to function?

The part he put on is crap, if you put a decent replacement screen on it'll work fine.

Are you sure? Because I don't wanna regret spending money on a new screen and it doesn't work. :laugh:

I've seen phones damaged by a repair bad enough that the touch will never work, but I've seen far more copy touchscreens that are useless.

Hi Guys
Just to say: may bad fake faulty touch "per se" works well under 4.2.2 and updated 4.4.4 also! It just prohibited "start" the phone with this digitizer attached! Both, phone and digitizer are fully functional and "compatible"..
