Oh dear.
After thinking that software was causing an alignment problem (pretty sure MultiIE DID make it worse), I reset the device to factory settings and it still happened. Each day I needed to recalibrate the machine several times, making it unusable.
So it is in the post to HTC Europe for repair and I am without my MDA Compact!
Let's hope they fix it and send it back soon.
I am having the same problem with my O2 mini on which I have to realign the screen every hour or so. I have done many hard resets but there was no improvement. I have tried many ROMs as well. So I suspect its a hardware problem. Any suggestions apart from sending it to the service centre?
I'm having the same problem, I think our only solution is to take our JAMs to a service center
me too... but already pass my warranty period~!!!! da*n :!: some1 can tell me how much to fix this problem?? oh, again,
I think it's better
Maybe a little to early to say but I just got my Magician back from the HTC Europe centre.
They have simply re-flashed the Rom back to 1.12 (May 2005). When I first unpacked it I thught the screen was out of alignment again and rang to complain.
The thing is, I have since set it, played around with it for a few hours and it seems absolutely fine.
Since all my testing previously was with the November ROM (1.13), and the problem started around December time, I wonder if it's a problem with the new November Rom?
I'll keep you posted on what happens over the next few days.
Yes it was too early
Seems to be a problem still. What happens is it loses alignment after being switched off for more than a couple of minutes.
HTC are ringing me back soon.
It's going back again!!
HTC are taking it back for another look.
Observations
I have been living with the problem, and over the period have noticed that sometimes problem is not at all there, and sometimes its pretty bad.
Interestingly, when the problem crops up, if I press the screen a little harder with my finger, the screen just returns to normal alignment. So now I just press the screen instead of doing a screen alignment - takes only 1 second.
yeah~! same exacly here... just pressed it hard then it will back to normal but sometimes not, and still, im not happy with the quality of xda mini... for such an expensive toy, this \things should not happen to too many ppl.
thx,... waiting for your update... and pls let us know the cost...
Yippeee - it's fixed
Just got it back again from HTC Europe.
They have replaced the LCD and I now have perfect screen alignment again. I can even turn it off and the problem doesn't come back!
Very, very happy.
Repair was under warranty so it didn't cost me anything.
HTC have provided very good service to me on this. I am very impressed that they continued to listen and fixed the problem for me.
mini screen misalign
just started experiencing this about a week now, very iritating, and a bright dot appeared on my mini at the lower left edge, its especially obvious wen playing a video with dark or black scenes coz the dot is really bright
i still have warranty til may16 i hope i dnt have to bring it to the service cnter
My touch screen has been getting out of alignment quite often. 3 or 4 times a day. I'll go to use it after leaving it on standby, and the touch screen alignment will be off by a half centimeter or more. its making very difficult to use. Sometimes very difficult to even get to the settings screen to realign it. I'm using a screen protector and to use my fingers instead of the stylus often. could have of this be having an affect? or does anyone have any idea whats goign on? thank you for any help you can give me.
Dan
I had a similar problem as well. Its kinda scary. Do you think its a software error? or could it be hardware *gulp*
I had this problem with some devices I issued out at work. I put screen protectors on them, and all kind of weirdness happened, and the screen getting out of alignment was one of them. I removed the screen protectors, and the problem went away.
Wizard platform has often that claim from many users. I'm not sure if working without screen protector is suitable for you and don't know it will help. In my case it did not.
The problem of kJAMs is related to the screens HTC used on this version. Unfortunately there is not software remedy. Some users attempted to change their devices under guarantee. Some are telling newer ROMs make the error less frequently.
You may also use "fire button + messaging button" combination as a shortcut to screen alignment page if you must live with this. Better than nothing ?!
fixed my qtek 9100
Well my wizard used to go out of alignment a lot. But I basically ruined it when I stuck it in my golf bag one day and let it get partially crushed while half-open...
The screen started to flicker a lot (in addition to not registering touch inputs). after a week it was unusable except by me since I knew where to push to get it to work.
Anyways, I gave up and asked around Hong Kong for people who can fix these PDAs. I found a store that offered to bring it to a specialist (no name given) for $380 hkd (~$50USD). Figured I had nothing to lose.
It actually works almost like new now. The slider is tighter, and the screen doesn't go out of alignment at all. I'd almost say its perfect except the "specialist" "broke" my volume slider when fixing it. Its not major so I decided against taking it back to the store for further repairs (3 month warranty on their work). But it took 3-4 days for them to fix.
I figure someone with the screwdrivers and stuff can probably fix your problem. But I didn't have the guts to try it myself...
Four things you can do to help
1. After time dust etc... gets under the rim of the screen and adds to the misalignment problem. Get a piece of paper and put the corner under the rim and get all the dirt out.
2. Sometimes software causes the misalignment - in my case it was using vjtoggletoday - so check or your software particular ones that change your today screen e.g. wisbar etc...
3. You could do a hard reset and try device in factory state for a while to see if it is a software or hard ware problem
4. Update to the latest rom.
Thanks for your help guys. Even though i didn't like your answers. I tried cleaning dust from under the border of the screen. It worked well for now. but it hasn't been more than 12 hours. I hope it continues. If i cant get it to stop i might have to sell my phone on ebay. they seem to go for only 50 dollars less on ebay than i payed for it in the first place. I hate to ask this question. but what could i replace this phone wiht that wont have this problem. and has windows? Basically what would you suggest as a replacement. And not the TytTn because i dont think i'll be able to afford that one.
Thank you.
lets hope that i dont have to fish dust out of my phone every day.
Hi, going through the emails on this list was indeed very useful. I bought an iMate JASJAM in January 2007 and it started giving me a weird problem with the screen.
The phone was working perfectly OK till Mid Feb when I started noticing that any application I opened (including phone or contacts) got closed automatically within a second. I observed carefully and saw that the 'X' on the top left corner of the screen was probably getting clicked on its own. I suspected it is most probably a screen problem and took it to the iMate service center. They promptly replaced the screen in 2 days.
It worked fine for 15 days before I am seeing the problem again. Could someone help me please. I am seriously dependent on email through my phone for my work. Would appreciate any sort of guidance, even if it seems obvious.
My JASJAM is 647XX s/n based
Thanks a ton,
Aditya Deshoande
If indeed the X is getting phantom taps, this is not a screen problem as such. In other words, you could replace the screen time and again and it would recur. The issue is that the screen gets pressre/pressed by the bezel around the screen. The screen is rather stupidly sensitive to touches even below the bezel. Pressure can arise from a slight twist in bezel, from heat expansion and from dust trapped between bezel and screen. You might try the "business card solution" - though it is not guaranteed.
I would also take a backup and do a hard reset. Try the problem apps without restoring the backup. This will identify whether it's software or the SA related problem.
f the problem is still there, I would demand a replacement not a fix, because if something is out of line it's not going to be fixed by swapping screens.
Mike
Thank you
Mike,
Thank you for posting a reply so quickly. I suspected it is not just a screen alignment issue the moment it appeared again. None of the fixes mentioned for the SA issue work. I just wanted to check if anyone has any suggestions to try something. There are no applications installed by me and I have tried hard reset. In fact the crosshair in the align screen application keeps moving without me touching the screen.
The problem is that this problem makes the phone useless because I cannot open the dialer. We need to be extremely careful of what iMate and HTC seem to be shipping out. This is a damn expensive phone to have such problems.
I will request for a replacement but would not be surprised if I am refused and told that it will be repaired since it is warranty.
Let us see if I need to drag them to consumer forum. I will, if the need arises.
Regards
Adi
Good luck Adi - I hope it works out. Yes that jumping around of the cross hairs does prove there is pressure being put on somewhere. Indeed HTC did appear to have largely resolved the SA and SA related problems - but I'm still seeing quite a few.
Cheers
Mike
Heats up during charging
Hi Mike,
Perhaps the problem is compounded by the fact that it really heats up if you charge the phone while it is still in the cover. The one with a belt clip that comes in the box
My screen does not respond to any taps anymore. Which in a way is good because I am at least able to call as well as send/receive emails.
Regards
Adi
Same problem here!
So my Hermes, which just got replaced by Cingular after the "red light..not charging problem" (Thanks for the pointers on that Mike!). But my new unit is also having phantom clicks on the x or in landscape the Start menu kept getting clicks. And I too got the moving crosshairs during screen alignment setup. Now the whole screen is whacked, not repsonding to any clicks.
Cingular are sending out another unit. I love my hermes, but seriously getting worried about the reliability of these units. I really can;t be without my unti working for too long, I'm stcuk having to go back to my SE P900 (with a flaky battery) or my SE S700 which sux.
It is a worry and very frustrating. However, when you get a good one it is well worth it. A hassle I know, but some folks here say they've been through 3/4 before being happy. This is the secret I think, put up with no physical defect and get an immediate replacement. Use a cheap mobile while you wait for the replacement. Most of the 'pain' comes from trying this and that and the other to get the device working and perhaps 6 out of ten times you fail. Use the warranty without hesitation. There ARE good ones out there!
My thought for today!!
Mike
Hi all, this is my first post on this forum but I've been reading for a while to educate myself.
I've got a Herm200 that I've been trying to troubleshoot but to no avail. I'm fairly certain that it has a hardware problem but I haven't been able to isolate anything.
Here's whats happening:
Occasionally the screen will come out of stand-by all white. This will also happen randomly if i touch the screen to perform a command. While the screen is operating, sometimes the buttons on the face will stop working, however the buttons across both sides will continue working just fine.
When the screen turns all white a soft, hard, or stand-by cycle will not always bring it back to life. The fact that the hard reset wont always fix the problem makes me think it's a hardware issue since the phone will boot-up with the the all-white screen.
This is incredibly frustrating especially since HTC wont accept any warranty claims in the USA on the Tytn.
At first I thought this might be a problem with the ribon connection between the screen and the base but i haven't been able to confirm or discount anything at this point. I have yet to find a way to consistently reproduce or rectify the problem so it's very hard to troubleshoot.
I pretty much have to take a second phone with me everywhere right now just incase i need to make a call. Please help! Has anyone ever encountered such a problem?
Thank you in advance!

Hi. This sounds very similar to a problem that I experienced with a HERMES100. I bought the phone off someone on Ebay recently - someone had obviously scrambled the radio on it. I re-flashed it, and it sprang to life. However, after a couple of days, I experienced a problem where occasionally the LCD would stop refreshing, all the pixels faded away leaving only a white screen. Under these circumstances, some of the buttons on the phone stopped working. Turning phone on/off sometimes cured the problem, or it would require the occasional hard reset. This would happen once or twice a day and I suspect thats why someone tried to re-flash the phone.
In the end, out of curiosity I took the entire phone apart, put it all back together again and now there are no more problems!! Totally fixed!
My suspicion is that it was one of the ribbon cable push connectors on the mainboard - possibly not seated properly, or a bit of dirt contaminating the connection. Obviously when I took the phone apart I must have re-seated it.
If you are planning to take your phone apart, please exercise considerable care because some of the parts are very small and easily damaged. I would recommend buying a proper kit to take it apart. I bought mine for about £5 off ebay. Particularly useful are the plastic spoon "wedges" used to gently prise open the case after removing the screens. Don't use a screwdriver - you will scratch the case.
Good luck.
wow... that sounds like exactly what's going on here, I actually even tried to disassemble it lastnight but didnt have the right driver set. thank you for the advice!
I'll look for one of those sets but what would you search for if i needed to find it?
Thanks again, I just got a set off of Ebay. Hopefully it'll be here next week
With any luck it'll be a connection issue.
I have had the exact same problem. Because I got the Tytn through work I made our IT department handle the issue and I am currently waiting for a replacement and to find out what happened.
Yep, it looks like the problems the OP is having are very similar to the problems we've been having over in this thread:
http://forum.xda-developers.com/showthread.php?t=291027
I'm beginning to think it's a hardware problem as well but not entirely sure.
People in the above thread mentioned that using the scroll wheel a while then moving back to use the D pad fixed the problem (very briefly in my case.) Once I use the center D pad button again it locks the hardware buttons under the screen until I make my device sleep and resume.
Somtimes rather than making all the front hardware buttons unresponsive the issue is that once I use the Down Dpad button I can't use the up button. Pressing up will make it go down, as will pressing down (at least that's working ).
Regarding the white screen - this sometimes also occurs. I can force it to white screen by putting a little pressure on the silver panel surrounding the top, right and bottom of the screen (I have an imate jasjam). Randomly when there's no pressure on the rim and I wake it out of standby, it has a white screen that can only be fixed by turning the screen off and on again.
Finally, the LED indicator seems screwy. Sometimes it never flashes. Other times it flashes sporadically (uneven intervals - we're talking maybe a minute between one flash then seconds before another). When I charge it sometimes the LED doesn't come on but nevertheless it charges. Sometimes if the LED is on it never turns green to indicate a full charge. Yet other times it comes on orange, turns green, then never switches off!
Is it possible that
a) The hardware button problems.
b) The white screen problem.
c) The LED problem.
are all related to some kind of connection going loose? Why would the hardware button problem be temporarily fixable with use of the scroll wheel if this were the case?
The other thread has fallen silent. I'm hoping that some of the gurus in here can offer some input here, even if they don't know the answer but can formulate an opinion. I know very little about these devices.
Thanks in advance guys!
PS - don't really know if I should start another thread, I've posted here as it seems like very much the same issue.
Anybody any idea? advice?
I had a similar problem with my HERM100. I didn't mess around with it too much, I just had Cingular replace it out of warranty exchange (thank god those original ROMs are on the wiki ). I did notice however that after doing a master reset, the screen would function again although I haven't messed around with it too much. I got so frustrated with removing the battery for 5 minutes and STILL powering on with a white screen that I just threw it in my back seat until the new one arrived.
I don't have these screen issues. I only have hardware button problems. It's so damn frustrating! I already own a replacement.
I just received a call from my girlfriend. I wasn't able to answer the phone with the buttons, only with a screentap. I also wasn't able to close the call with the hardware button. Since the side buttons work, I went to settings -> phone, closed it, and there we go. The hardware buttons worked again.
Why the heck is this? I truly hope for some wizz out there with some advice, since HTC would only tell me to send it back after replacing it with a new TyTN with same issues.
Regards,
DM.
Anyone anyone?

This is my first post as I've so far managed to cure all my issues from just reading the forum. However, I am now having a similar problem with the white screen.
I have a cingular 8525. It fell and the following day the call and end buttons remained lit and wouldn't turn off and they also wouldn't work.
I soft reset, nothing, I then removed the battery and when I turned it back on, there was a white screen and the buttons below still don't work.
I have read the other posts on this issue, but I need help on exactly what kit to buy to reconnect the screen cable and instructions on how to do it as I've never taken apart a phone before, although I have dabbled with other electronic devices.
Your help would be much appreciated, as I am in Jamaica and there are no technicians here who I trust to help.
Thanks in advance.
Below are links to 2 kits I'm thinking of getting. Is either one better than the other?

Both kits look ok. PDA one tells you a little more but the basics appear to be in both.
I'm curious though you soft reset and took the battery out, but have you done a HARD reset? I would always try this first before dismantling.
Mike
In my case, they also are always lit up when the screen is also active.
And no matter what ROM version, they occasionally stop responding. Side buttons keep working.

Thanks for the response.
I couldn't do a hard reset because the buttons weren't working.
I have made some progress with the phone now. Found a tech guy who looked at it for me. The white screen is gone, but the buttons still stop working from time to time.
All the connections seem ok.
Is there anything else that could cause the buttons to malfunction?

Nothing obvious.
Have you got applications installed that you have loaded - could be one thats playing up.
Have you now been able to do a hard reset?
If taking device apart and reassembling improved things it does suggest hardware though and might be worth double checking all those multi-connector blocks for good connections - i.e. take them out and in a few times to ensure any oxidation on contacts is removed.

If it wouldn't be a software issue, why is it, in my case, instantly resolved when going to settings -> phone with the side buttons?
i had this problem i took it to a guy who fixed the problem he said it was a very small tear in the flex cable which causes this white screen every now ant then and the buton problem , sorry to say its the cable problem and u need a very capable person to fix it or replace it with a new one . its very common problem baised on the guy who fixed it .

Exactly what is happening to me, no white screen issues, just screen taps and answering calls, I also have another problem where the PDA will not allow me to open anything, be it the start menu or contacts, it will open and quickly close again. I have had mine swapped through Telstra in Sydney, it worked fine for a while and then the same crap again. These problems started before I even touched the OS, so it must be a build problem. Maybe we should write a joint letter to HTC letting them know that there is a serious problem with their machine.
I have had the same problem, got my Tytn through work so we sent it back to the company that supplied it to us. Got it back yesterday and they had replaced the "switchboard". Not sure what it is but there was the problem. Had white screen and buttons not working.
The top part of my phone does not respond to touch anymore... it is impossible to bring down the notification bar... and once in a while the whole screen goes unresponsive.. tried factory reset but still the same problem..
am having the same problem since 2 days back
after reading some of the posts i found that the Digitizer For HTC G6 Legend A6363 should be replaced with new one i ordered mine from ebay
ebay.com/sch/i.html?_from=R40&_trksid=p5039.m570.l1313&_nkw=Digitizer+For+HTC+G6+Legend+A6363&_sacat=See-All-Categories
waiting for the item to be delivered
I've also got a touchscreen issue: the area of the notification power widgets is unresponsive... the rest of the screen works fine, but I don't know for how long :/

Do you have widgetlocker, by any chance ?
Or a lockscreen replacement which disable the notification bar during the "slide to unlock" state ?
I didn't know there was such thing as widgetlocker. I use CM7 latest nightly, never seen that thing.
I also facing this problem from last 2 weeks and i also think this is digitizer problem. If anyone else found the solution else changing the digitizer, then please post.
This is beautiful phone but htc added a poor quality things in it, due to which many users facing such problems.
Nah.. I dont think its because of widget locker.. its the digitizer..
well that's a shame, gotta buy a new digitizer on ebay after just over 1 year of use...
I know.. this sucks... Im planning to upgrade though.. Any of u guys have any suggestion?
Depends on your carrier if you want suggestions for an upgrade.
...but that would drive the post off-topic.
Sent from my HTC Legend using XDA App
I have the same problem. my screen doesnt work anymore because some water got in from the grill above the screen :S
should I try to take apart and dry off or shall I buy a new digitizer directly?
I think it may be a good idea to try disconnecting your digitizer and reconnect it as it just might be helping. I did it on my girlfriends legend and it has been working perfectly ever since. Maybe a good idea to at least try that before buying a new one. So i guess it could be in the connector to? At least this worked for me.
My touch screen dosent work at times. but after rebooting the phone the problem becomes solved. But the problem comes again after a week or so. Any suggestions guys??

I also have this problem, but if I wait a couple of minutes the touchscreen
becomes responsive again. Half of the screen works when it's unresponsive (right half of the notification bar and down). It's quite annoying but I cannot afford a new phone at the moment.
I'm also wondering if this might be temperature related, this problem reoccurred very often during the summer but stopped during the winter. But now (spring) it's back again.
My problem got worse and the phone became totally unresponsive, changed it, got a new phone.

exact same problem here, mine works when it feels like working, totally random, I simply can't understand why, I doubt it's the temperature... I think its in the device theres something wrong, I smack it numerous time and it works right after a big smack on the screen, or rub your whole hands on the screen, also, the angle you are holding the phone affects this problem, if none of these work, a phone restart always makes it work at the beginning. Oh boy did my phone took and taking much beating... oh well, I wish I could permanatly fixed the problem here, as I was thinking of handing the phone to my brother when I upgrade, I'm using CM 6.1.
I still recommend the same thing that i posted earlier here, her screen still works perfect.
I had the same problem few months ago. The problem is with the touch digitizer. I bought a digitizer on ebay and replaced it myself. After that my phone has been working fine. Its not that hard to replace it if you have a small knowledge about hardware.
I use to get that unresponsive screen issue only in the summertime, plus it gets worse if I add humidity (read: sweat). I just need to give it some time then to dry off/ cool down outside my pocket, and it's all fine again.
