Power button less "clicky" - Touch HD General

My power button has become less "clicky" like something is making it stick inside, or some part of the button has damaged or fallen out. It's very difficult to switch on/off the phone disply, because the buttom seems to have sunk or is stuck.
AFAIK, it hasn't suffered any bumps or knocks and is always stored safely in my pocket.
Any suggestions?

Probably small plastic bracket under external switch is broken. Don't know if you can replace only this part or whole button.

So, how can I check this to see if this is really the problem?
Any disassembling guides for the Blackstone (good ones)?
What else could the problem be? The external switch looks fine, but I can't really get a good look under it.
Problems with dirt/dust buildup?
Anyone else had such similar problems? Is it a common problem?

Would have to agree with above, looks like the small plastic bracket under the external switch has broken

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:

HPN
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!!!

[Q] [HELP] Hardware Buttons Pressing Eachother

I just got an HD2 so I could run mango.
Only one problem though.
The hardware buttons are pressing each other.
For example,most of the time when i press the back button ,it presses the power button instead. It's like the spring or whatever is pressing down both if them and hutting the power button first. It also happens a lot when I press the Windows button,which will press down the back button instead. It's definitely a hardware issue. Has anyone else had this issue? Does anyone have a possible fix?
Thank you!
Somehow, the flex assembly for the buttons became misaligned. You will have to take apart your hd2 to fix it..
Has anyone else had this problem and successfully fixed it?

I watched the disassembly video when I replaced the housing of my HD2, and you have to take it apart pretty much completley to reach the buttons.
The risk of damaging something is pretty high, isn't it?

You got your HD2 used? I would guess it's a sign of wear.
I'm experiencing the same problem, not most of the time, but sometimes.
Since I'm on Android I started using Button Savior some time ago, hopping I can preserve my buttons a little longer. Don't know if there's a similar app for WP7.
...but sooner or later it'll be time for a new device.
Yeah, you will have to buy new tape or use CA glue to seat the lcd/digitizer assembly back onto the chassis when you put it back together. The risk of damaging isn't that high if you be careful to not touch the button contacts (they will fall off but it can be fixed with tiny drops of super glue) and careful not to rip any flex cables.

HD2's innards: Attempted vibration motor fix gone horribly wrong.. HELP!

I'm hoping somebody with some knowledge of the HD2's innards can help me...
My vibration stopped working on my HD2. I found the plastic LED flash cover to be 'pushed in' (with the help of a couple xda threads I dug up). Others said it was an easy fix: Open the case and push that piece of plastic back into place.
I opened up the case to correct it. But after putting it back together not only does vibrate not work, but the volume keys, speakers (both earpiece and speakerphone), flash, notification led, and camera all don't work.
I obviously screwed something up, but I have no clue what it could have been. I was very careful. One thing I'll note is that when I pulled the case apart, the plastic volume rocker went flying. When putting the phone back together I got it back into place so that I THOUGHT it should work (it was seated properly and felt "clicky" for up/down movements.
But clearly wasn't just the volume rocker that was affected. It doesn't seem that I pulled anything else loose or anything like that...
But no luck, all that I listed above is non functional, and what I'm left with is a glorified 3.5 in tablet
Any ideas?? Thanks in advance!!!
Snapped a couple quick pics which may help:
http://i50.tinypic.com/mmsa36.jpg
http://i47.tinypic.com/sl1kdx.jpg
Unfortunately when comparing these to other pictures of the inside of the HD2 that I found online, I fail to see any differences, or anything I could have inadvertently screwed up.
Most likely you screwed up(or disconnected from motherboard) somehow your main flexboard, but your picture are not usable for this, you should take off your motherboard+main flexboard from chassis to have a full view!
You probobly just disconnected a small cable. I have no idea of the HD2 innards but did multiple repairs of small stuffs and the flat cables hold in place by a plastic clicker pull out easily - just reopen and check them all, you should be fine.
Thanks for the input! I figured it's something like that, just one small cable. But I didn't even take off the board at all... The pictures show the full extent of the disassembly... Do we still think it's necessary to disassemble it further?
I checked all visible connections, but yeah, maybe I somehow yanked out something that is NOT visible. I'll try to check again today... In the meantime, any more ideas from anyone else? Thanks!
For al that to be not responding I would assume main-flex damaged or as mention before maybe connection to mainboard got moved during pulling cover !
Volume button can be troublesome, sometimes the little plastic caps come off but if it felt clicky should be good in that respect.
also be very carefull of thin spring metal legs that contact antenna pads on back cover, one near screw above & right of vibro motor looks a to be a bit flat. They bend easily & break easily too ...
Have u tried starting up the phone without the backing? I had this issue when I painted my housing the led cover was stopping the motor from spinning but if i took out the backing it works. So I just trimmed the led cover and now it works.

I'm nooby with regard to this stuff; I only attempted the repair since I read in a couple other threads about multiple self-proclaimed non-super-tech savvy people were able to open it up and move the plastic LED cover for an easy fix.
So what exactly am I looking for with regard to the main-flex? Where is it? I thought I wouldn't really see that unless I removed the board which I haven't done... is it still possible I knocked it loose or damaged it? I didn't think that would be possible since I ONLY removed the back cover (though it does take a slightly uncomfortable amount of force to do so, so I guess anything can happen...).
If not the main flex cable, is there anything else specific to look at which may be disconnected? It seems to be all the stuff at the top of the phone that fails to work (camera, speakers, vibration, flash, volume keys). While the stuff on the bottom (other hardware buttons, charging jack, headphone jack, etc).
THanks!
I have given up. After being stumped briefly how to hard reset the device without the volume keys working (I have Android installed), I was able to do it via ADB from the Android dev kit.
To ebay I go...

HTC HD2 assembly problem

Hi guys,
I just disassembled my HD2 to replace my broken digitizer and touchscreen.
But now i'm stuck with a problem.
What shall I use to glue both items together again?
And the keyboard makes some issues.
I tried to place both parts over eachother to see if they fit but I can't press the keys after it.
Seems like they are stuck.
That's why I didn't want to use superglue because after assembling it I wouldn't be able to change anything.
Maybe pictures tell more than words.
http://www.youtube.com/watch?v=t8Q7mXdcJ54&feature=player_embedded
hope that helps you
thanks wasn't the information I was looking for but nevermind
I assembled the device now .. but the next problem occured ..
the hd2 is loading without problems (led shows it) but when I try to power it on it's completely dead. nothing happends
with my old touchscreen it was at least possible to power it on.
my question is:
could the new soldered touchscreen + digitizer be broken? or did I break something during disassembly and assembly?
To be honest I didn't see any mistakes I made.
It's not my first time repairing stuff like that because I used to repair notebooks as a hobby.
Still i'm unsure what the heck is going on with my phone atm.
did you check if the flex cable from display is in the port, there is an white stripe that shows how far it must in the port. Did the phone vibrate when you pressed power button?
I checked the cables and found nothing suspicious.
and the phone didnt even vibrate after trying to power it on.
I'm trying to get a new hardkey board (i hope you know what I mean).
Had problems with the keys being stuck and maybe I killed that one by trying to assemble it.
if the phone doesn't recognize me pushing the power on key it's no wonder it won't do anything.
hope this will fix the problem

Most likely something is wrong with your Power button, but you should turn it on with 2nd method:
- pull out battery;
- insert usb cable(connected to PC)/charger in your usb port;
- insert battery.
This way it should turn on whatever OS you have installed on.
If your OS is Android through MAGLDR, connecting it through usb should turn it on by default, unless your battery is not dead!
Check it out!

I just did as you said and yeah the phone came to life.
so there is definately a dead power button (probably the board is broken)

Glad to hear that!
Definitely you should replace your keypad flex!
Did you fix the problem with the hardware keys
Hi,
I have very similar problem.
I changed the touch screen on my HD2 and after reassembling I cannot get the hardware keys clicked.
I ordered a brand new key board and brand new plastic buttons. I received them but situation is the same.
If somebody can explain is there any trick during adjusting the plastic buttons to the clickable "small dots" on the board - please help me.
Best Regards

Normally this is always down to glass digitizer not being aligned correctly when stuck to LCD.
0.05mm can make all the difference here.
You need review current digitizer position & pre test assembly to centre chassis without tape for a test run on button function.
Also check button board position is exact & located correctly in the pin holes at each end of the board.
original board quality is normally far better than most of the very cheap eBay pattern parts but one or two sellers offer a decent board around $4.50
Also clean all old tape from back of LCD & centre chassis plate so parts fit flush & once all checked new tape can be added, I also use small spots of up40 adhesive sealant near corners & near middle edges for final build up as holds far better than even the best tapes & gives an original strength & long lasting flush look to final job plus us easily removed with razor blade if repair ever needed again.
Super glue is a BIG no no NO.

It is not the case in my case , because I ordered full set (digitizer + display) and they arrived factory assembled.
But you are definitely right - 0.05 mm make the difference. I think the problem comes from the fact that the board with buttons cannot be firmly fixed to the 2 small juts on the chassis. You know the plug of the buttons board is on the tail like extension. Probably when I try to cover the buttons board with the LCD+digitizer - the frame of the LCD slightly pushes the buttons board and the juts on the plastic buttons cannot be fixed exactly on the top of the actual buttons on the board. Anyway we are speaking about precise fixing something around 0.05 mm over something else, which is exactly same size... and in the same time you have to fix this without any visibility.
I will continue trying. If you can give me any other ideas - I will appreciate this.
Thanks

Do not rule out the LCD/Digitizer assembly as the china combos are prone to not the best accuracy of assembly as sounds like maybe LCD is mounted just a fraction too low on the digitizer perhaps.
Button board should be fixed via 3M style tape & most replacement boards come with tape ready for fitting.
worth making effort with button board to centre chassis to mount securely then mounting lcd to chassis without tape for a trial assembly & try and check for possible issues such as bent chassis or old tape not removed sufficiently or new assembly alignment not the best.
I would also recommend using original plastic button strip as the copy ones are not always good & have had experience with them before.

[Q] HD2 Disassembly Errors

Hi,
I just recently disassembled my HTC HD2 to replace the digitizer + lens and now it works, but I believe I may have scratched the LCD during process because now there are scratches/blurring on the top right portion of the screen (as seen in this pic imgur.com/vYjbn)
I just want confirmation that it definitely is the LCD that's causing the issue as I'm about to order one to fix my mistake, or if it's some other component that I overlooked.
Also, the up volume button doesn't work but the down one does. I've tried probing it with tools (since I lost the yellow/black bumper thing), but it's unresponsive no matter what. Anything I can do about that?
Thanks in advance!
cracked LCD, new LCD needed ...
Yellow black popper cap is needed as that is the button ...

The bottom one works without a button however, when I probed it with a flathead. For some reason the top one doesn't work. I don't think not having the button is the sole reason, perhaps a link was broken or shorted.
Black part in cap is the contact pad to bridge the points on the button board, without the cap the button has no feel & no function. Never seen volume work when missing & I come across a few that have been missing or temporary missing during assembly.
