problem with keys after short period of time

I recently replaced the housing of my XDA mini,
but now I have the problem that after a while
- I couldn't figure out what exactly triggers it -
the buttons don't work anymore.
If I remove the SD-card sometimes they work again.
I think it might have something to do with the
top 2 screws (antenna cover).
Does anybody know for sure?

Hardware buttons doesn't work anymore on my Trinity.

Hi all, my Trinity's hardware buttons doesn't work.
The 2 softkey hardware buttons, the red and the green button, the ok button and the Start button seems to be broken also if they have backlight. All the others buttons are ok.
I've tried to softreset, hardreset and flash the ROM (I'm using last Ervius ROM). After flashing for the first time the buttons were ok for a littewhile but now they seems to be broken again even after several flash. I've also tried to downgrade to wm5 but nothing change. I think that is an hardware issue and I'm going to try to fix it by opening my Trinity hoping that is just a flat connector pluged out but if someone else has experienced the same problem and has to suggest me something is really welcome.

I experienced this myself, and replaced this item:

keys are stuck
Mine also, but solved it after a couple of days (temporarily). The hardware buttons problem seems to be related with one of the keys stuck. If one of those keys is stuck none of the others work. I tried "fast" double clicking on one key at a time to unstuck and it worked for me. Mine has been working for two weeks with no problem. Anyway I ordered that part "just in case".
So before opening your trinity try to unstuck the keys. It seems to be related with humidity conditions and carrying the phone in the pocket (just a guess).

I'm going to try this becouse during the last 4 days sometimes the buttons work so.... thanks!

Ok, nothing work.
I've also tried to open the device but looking behind the buttons pad fortunally/unfortunally there isn't an evident hardware problem.
The only solution is to replace the pad.

Hi to all.
I have had buttons not working on my trinity for some time. was tempted to send it back for repair but i did not want to be without my phone and did not want to have to stick the old wm5 rom back on!!
I took my trinity apart too see if i could see anything wrong. and got it down to the keypad. one thing i did notice is that there was a lot of dust. also around the small disks that provide the buttons, there are 3 small holes in the sealing sheet. seems that the construction of the switch array is circuit board at the bottom, with small tin disks on top, all held in place with a thin plastic sheet.
The tin disks 'pop' inside out when you press the buttons, making the contact for the switch. On the old nokia phones, these disks got deformed and this would make the button work but with no click. I had a click but no button operation, and with the holes, and all the dust i found, i figured that it must be dusty contacts.
so here is how i managed to fix my buttons for free:
1, strip the phone to get to the keyboard circuit (i used this link clicky)
2, clean all the dust from the buttons
3, start to tease the plastic film from the front of the board (i used a sharp knife but mind your fingers and take care not to damage the board)
4, once one corner is up you should be able to slowly pull the film up (take care not to damage the disks as the plastic comes up but make sure the disks stay on the plastic sheet)
5, dont pull the sheet totally off otherwise you will have a job getting it all to line up after.
6, get some alcohol or head cleaning fluid on a cotton bud and clean all the gold contacts, as well as the insides of the discs.
7, slowly rub the plastic film to put it back where it came from, taking care to get the disks in the center of the gold contacts.
8, rebuild and test
All being well you should have working buttons again!!! It seems the design of the buttons lets dust inside the workings.
Hope this helps someone with clicking buttons but no action!!!

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

Screen stopped working, only backlight after trying to fix vibrate

So I tried to do this: http://forum.xda-developers.com/showthread.php?t=376035
My screw was loose indeed. In fact is was so loose it fell out before I had opened it completely.
I tightened the screw, closed the cover, turned it on, and... nothing. Only the backlight of the screen, but the screen stays completely BLACK. Nothing. (I know the phone is working though, because if I hold the off button I'll hear the "boink" sound)
I tried this:
- With and without SIM card.
- With and without tightening the screw.
- With and without the power cord.
Mind you I have NEVER had this problem before.
What is going on here? Did I **** something up badly while opening this phone? If I did I am going to be super sad, so please, help me!

Anyone?

I basically have the same fault mate. My vibrator lock screw was loose and it made the phone rattle.
I opened it up and probably either tightened the screw up too much and killed something on the mainboard or 'pinched' the lcd flex ribbon ( rusty gold coloured thing- it plugs into the small white ribbon connector on the MB ) with the opening tool.
Anyway - the phone could take calls , it seems to be working ,although I have no display , and the keypad buttons are all lit up very brightly , what scuppered me was with the constant case opening I eventually managed to break the power microswitch off the MB and I now have to use the reset button to power the phone on.
I don't want to waste money buying a new lcd screen for a phone which might be terminally damaged due to a mainboard fault , anyone narrow these faults down more ?.

shameless bump.
BUMP !!

Im just fixing my LCD on my P3600 and have it in bits,
is the display connector definitely pushed all the way in?

Yeah m8 - AFAIK it is all the way in , I am certain that it is the flex ribbon connector that is broken.
For anyone else interested in this or that has the same problem - there is a program called ' my mobiler ' which can be found in the forum somewhere , using it will tell you all you need to know ;
i.e = if it is the phone itself that's broken , or it's a damaged display.

[Q] Strange screen Problem HD2

Hi guys, first post. So heres the problem. My HD2 screen is not glued properly to the base of the phone and it has a little space between them at the bottom right corner ( next to the Power button), whenever i press the screen to close the gap the phone freezes, and i have to remove the batery. It is getting really annoying couse i cant even put the damn thing in my pocket without it freezing. The hardware keys dont even work i just have to restart it. So my question is does any1 know of this problem and can he/she offer a way out?
Sorry for my english. thanks in advance

Sounds like it been opened before & had not the best assembly.
Would imagine hardware button ribbon is torn or pulled out of socket hence no buttons.
freezing issue could be down to issue with digitizer ribbon or button ribbon or worse ?
Do you have any issues with screen touch & do you know full history of the handset.
If black Void sticker is missing from case screw near battery pins then you know it been opened & most repairs including so called specialists are poor from ones I've seen.

I know this is the last thing you want to hear but if it were my device I'd take it apart and redo the assembly myself. Theres plenty of how-to videos with detailed steps. Hope this helps.
