Hardware problem (buttons), please help. - P3600 ROM Development

over the past few weeks some of the buttons (namely left soft key, up and left) have stopped working, i've tried numerous roms just incase but it's definatley a hardware issue, now, i've dismanted the phone using the diamantos guide to see if anything jumps out at me, gave the phone a damn good cleaning whilst i had the chance, put it back together....but nothing, everything seems to be in order, all components in their rightful place but i still cant work it out, does anyone know if this is a common problem or if theres a fix as i've been unsuccessful in my searches.

actually, i just found the solution and it worked a treat, thanks anyway people.
btw, if anyone would like to know what i did then i'll be more than happy to share the solution.

I'll be more than happy

please share your solution with us, I have the exact same problem

ok, no problem, heres what i did.
before you start please be aware that this is a very delicate procedure and you should take care as this may naff up your beloved trinity.
ok, i first disassembled my trinity using the dimantos guide located here http://forum.xda-developers.com/showthread.php?t=311463,
now, when you get to the keyboard / button pcb take it out if, you look closely you'll notice theres a thin adhesive plastic cover covering the metalic buttons, very very carefull peel this back (i used a sharp knife to get to it), making sure not to completely remove it, try to only expose the underneath of the buttons in question, you'll see that the buttons come away with the plasic leaving the underneath exposed, now, using a cotton bud and some lightly applied alcohol clean the contacts then when all is done, replace the plastic and make sure its firmly pressed back down you may notice it making a different, kind of sharper clicking noise when depressed than before meaning its worked, repeat for all buttons.
i think whats going on here is the gum or glue from the plastic film has "leaked" if you will, onto the plates meaning theres no contact from the buttons, this would also account for the very slight change in sound when you now press the button.
i found this info here http://forum.xda-developers.com/archive/index.php/t-289737.html

i have the same problem with the front hardware keys. They last around 1 year, i had them changed under warranty the first time but now they are failing again.
Thank you! now i just have check for tools and some courage because i fear damaging my good old trinity.

....hi to all dear friends!!after half an year of very hard work my trinity has the same problem....only central botton working but,the superior two,works if I do an hard reset!very strange!changing a lot of different roms,from w 5 to w 6.5 the problems doesn't solve...!
- I'd like to make your same operation but I'd like to know first if you too have they working on hard reset before trying....
thanks a lot and merry christmas!

yes, even after a hard reset they work for me, its as if it was brand new, bare in mind you may have a different problem so if your gonna try this, TAKE YOUR TIME.

I tried doing this but found no plastic cover above the metallic buttons. Maybe it's because mine went for repair with this problem before, dunno.
I don't think i can mess with the metallic part so i guess i'm stuck with this unless i buy a new keyboard.

it's more of a very very thin laminate, like sticky back plastic than a cover, it should definately be there unless they replaced the PCB with a different model, otherwise the metalic buttons would just fall away. Again, they may have used a different version of the PCB. You can actually buy the PCB and replace it yourself. (here http://cnn.cn/shop/p3600dopod-d810-keypad-p-1825.html )

tapping problems - touch screen is not working

Using my htc device suddenly touch screen went off and i could'nt use the stylus at all. The strange thing is that all of the other keys are working good. I tried hard reset the device but nothing happened. Now im stuck in the screen "tap the sreen to set up your windows mobile based device. Can anyone please help? Before the appearence of the above problem i was using google maps, if this helps.
many thanks
Does t have a crack in it? If so then it needs changing, if not then probably the ribbon has come out. Is it under warranty?
no there is nt any crack! everything was good and suddenly while i was tapping to check some maps, stopped.
Sorry for asking but ribbon is that thing above the screen? Is it possible to come out so soon? (6 months). and finally does the warranty covers ribbon change?
Sorry for the above questions but i really dont know what to do!
many thanks
call the company where you buy it from and ask them

If it's only 6 mths old it shoud be under warranty, so take it back to the place you ought it.
If you are determined to try to fix it yourself you have to do the following.
Remove the battery cover & battery.
Remove the 4 small screws
Remove the back-case by running your fingernail round the gap (hard 1st time then easy after that)
Remove 4 more screws
Remove front-case from the middle
Remove the motherboard assembly from the front case and unplug the screen/digitiser assembly, carefully pull that off the motherboard (again not easy 1st time).
You will now see the small digitiser ribbon at the bottom coming off the digitiser and disappearing into the bottom of the screen. It's very easy to take out and not easy to put back in. I use some flat-bladed tweezers to do mine but sometimes it takes a couple of tries. Obviously it's much easier if you are fitting a new digitiser because it's not fixed to the screen like yours will be. If you try to remove the digitiser chances are you will crack it. I re-fitted mine after removing my broken one by using thin cut strips of double-sided tape.
Before you do anything else, just clean with sharp knive or razor between the screen and the cover.You will be surprised how much rubish is is in there.
this things are keeping the screen pressed.
Hope it helps
many thanx 4 the instrustions guys. i'll try that. if everything ok i'll inform you. if not i'll give you my bank account number to deposit money in order to buy a new one.
many thanx again

Touch screen not working on HTC TP2

So the touchscreen no longer works on my phone. So that pretty much means i can't unlock my phone, which means i can't shut it down, which means it's useless.
During startup, i got the very generic services.exe error, which leads me to believe that since there was an error with the exe, the service used to poll the touchscreen isn't running.
So before you ask:
- I have power cycled the phone several times (still same result of nothing
working)
- Windows Mobile upgraded to Verizon's release of WM 6.5
- I have not installed any new software in over a month
- It has never gotten water on it
- I have hacked the registry, about 6 months ago when i got the phone
- I did mess up one of the registry keys, replaced the key name with a
't' and couldn't remember what it originally was, but the phone hasn't
acted up. Can't remember what the location of key is either, but i
was trying to remove the vibration whenever you touched the
screen. There are two locations for it, and i eventually found the
proper one though.
So if anyone has any ideas short of hard-resetting the phone, please let me know. Is there any sw that can run my phone via the computer?
Thanks
Touch screen not working
I have to got the same issue, ever tryed hard rest.
flashed new rom. still nothing...
Solution
Okay, I've just had this problem with an HTC Touch, and I think this works with any HTC that has a "digitizer" rather than an all-in-one touchscreen (I think newer phones have digitisers).
I'm not sure if this will always work, but I've just done it - sometimes the inactive touch screen is "broken" because the layers are stuck together (so the phone can't tell where the touch is, hence unresponsive). With mine, I looked at the screen side on and could see a kind of "oily" patch in the light.
The solution is to get masking/gaffa tape - the very sticky brown one. Stick it down on the screen/digitizer and then keep pulling it off - this pulls the layers from each other. I kept repeating this lots before it worked - and in the end I pulled the top layer completely off (I think you should pull from the top of the phone, as the layers need to be attached at the bottom of the screen/digitizer). Once it pulled away, I gently lay it back down (after panicking!!) and hey presto it started working again.
Good luck!
I have the same problem, oily stuff migrating from a corner inward....
And you're suggesting we do what now? I'm not following this.....
He suggests you put masking tape onto your screen, to pull the stuck layers apart. If this doesn't work, you can always replace the digitizer.

had this problem this se xperia x2
Unbelievable...this just worked for me too! I gave up on this phone 6 months ago...now back to flashing ROMS, yeah!
Thanks a lot!
It is now!
Thank You! And I didn't even have the proper tape, just some cheap sellotape...did the trick though!
Thanks again, You Rock Dude!
Very Much Appreciated!
(And a Big Thanks to Andrew for the heads up!)
If I had read this 3 weeks ago i wouldn't have wasted 35$ on a new screen.
It gets worse, the new screen doesn't work. But this 1cent fix DOES.
The new screen was never calibrate-able.

I have exactly the same problem! The touchscreen of my xperia mini is not responding at all!
Can you please be more precise? What do you mean "pull off the layer of the screen?" Do I need to disassemble the phone and mess with the hardware? That sounds pretty scary!!!

I think he had some sort of a screen protector that was interfering with the screen...
You can try to run your fingernail along the edge of the screen - between the bezel and the actual touchscreen. Quite often something stuck in there is causing the touchscreen problem (or there is a deeper hardware issue and the touchscreen is just not functional).

I'm in the same boat. Normally I wouldn't be afraid of a little digitizer replacement. But on the TP2 it looks like every single bolt and screw needs to be replaced and in the only video I could find about it, the guy broke the lcd in the process.
Hoolexer
W0W.... You are awsome,,, Now I can sleep at night. Thank You So Much
salterlee you are a genius. I just had this same problem. I putted some masking tape to the screen, didn't had to pull the front layer out, and it worked wonderfully.
A little suction goes a long way!!

Same thing here.
I used a suction cup from my bathroom mirror that held a razor or something and made sure it was decently moist so once i stuck it to the screen i could slide it up and down the entire surface and worked like a charm..... no tape to throw away.
thanks for the inspiration cause i was gonna make this touch into a throw.

Secret to Soft Resets?

Hi.
As much as I like my Tilt 2, it's driving me crazy. Why? Because somebody decided to put the reset button underneath the back cover on a Windows Mobile phone!
Because of all the software I have installed, I find that I have to do frequent soft resets. When the OS is running, I can do this through software. If the OS freezes up, however, I have no choice but to remove the back and do a physical reset.
I am currently having major problems with Wunderradio causing frequent freezes and I'm afraid I'm going to wear out the back, snapping it off and on so often. Am I missing something? Can anyone tell me if there's another way?
Thanks!
You didn't tell us wich rom you run. What you could try is this.
In this thread there are different options of soft resetting:
http://forum.xda-developers.com/showthread.php?t=585813
Or you can download quickmenu and set it to you're start button (the hardware one). If my sense freezes I can always get quickmenu to start and it has an option to soft reset
http://forum.xda-developers.com/showthread.php?t=340352
I have used this to great success: http://forum.xda-developers.com/showthread.php?t=544016
Basically it gives you four choices when pressing the power button: Sleep, Restart, Shutdown and Cancel. Look through the thread for several really nice skins.
These days I use the cab attached; it gives you a WiFi on/off shortcut and a Reset shortcut. It was made for Sense 2.5, but it might work anyway. No harm trying.
I understand what you mean. I've found my device doesn't lock up as much so it hasn't been that big of a pain for me. But when the device first came out i read on some winmo news site about someone that drilled a hole in their case.
Here's one example that i just found from a quick google search. I'll probably do this pretty soon with my dremel.
I used a micro drill, and measured and drilled a hole in the case of mine. Looks like it came from the manufacturer, but I built scale models for years, so it was no big deal.
wow im gonna have to do that, i hate having to take my clear plastic case off, then the back off the phone, just to sr. never thought of drilling a small hole. last thing i woulda thought of is defacing a really nice looking (and expensive) phone. but this is gonna be a must-do for me. please post any tips or techniques that will help me and probly a few others from screwing it up (how to pinpoint exact hole location on back cover, how to avoid crappy lookin jagged hole, etc anything maybe learned thru doing it)
thanks for sharing!!

Tmo was smart enough to put the reset hole on the outside of the case on their version of the TP2...but forgot that on the HD2, and I miss that even more than I miss the hardware keyboard!
For those of you who are interested in drilling a hole in the side of your case to get access your reset button, I might suggest that you first mark the exact spot you need it drilled, and then take it down to your local hobby (model) shop...they will most likely have (or know) somebody that can drill you a nice clean precise hole exactly where you need it, if you slip them a little cash. As MustangBond (p51d007) mentioned above, model-builders will have both the tools and the expertiese to do this much quicker, easier, and with more professional-looking results than the average Joe could make happen
Solved...Thanks!

You're right. Guess I forgot where I was! I'm running the stock ROM for now; I have enough problems, without adding yet another variable.
Thanks, everyone, for your suggestions. Of course, a hardware button is the obvious solution. I own a copy of AE Button Plus and actually had the PTT long press set to soft reset, but it wasn't working, and I'd forgotten about it. However, I'd downloaded Rhodium Keyboard Controller a while ago, so after reading the comments here I decided to give it a try. I now have a working soft reset without having to drill a hole in the back. (Yes, I had considered that. However, I'm NOT a model builder and it would be a big deal for me!)
Some of the suggested applications look very interesting as well, so I'll be looking into them.
Thanks again!
For me the issue is even worse because I use a transparent plastic shell snapped onto the back and front of the device for protection. It is not all that easy to remove.
I just used Keyboard Controller to make the device soft reset upon triple clicking the power button.
Obviously does not work in all cases, but most of them.

[Q] Random touches with replaced digitizer

I replaced my digitizer on my inc and now it will randomly have touches on the screen. I have no idea why this is happening. I have tried two different digitizers with the same problem. It gets worse, i have tried the first digitizer i got on a second phone and this phone has the same problem.
I am running cyanogenmod and have "show touch" turned on so i can tell when its happening and where. The random touches appear to happen all on there own. I can not reproduce them. They do generally happen in about the same spot/spots each time. There are two general areas and when its registers a touch it moves a little, meaning when it touches it self it dances around a little. how ever if i turn off the screen and turn it back on it usually fixes the issue for a while.
Any idea what may be causing this problem and how to fix it?
Funny, I am having the same exact problem. Replaced my digitizer about a month ago and routinely get the "random touches" or just general unresponsiveness while using my phone.
I just assumed it was a side effect of my less then perfect installation but now I wonder if the digitizer itself is shoddy.

Have you considered the trackpad as the possible culprit? I know when my phone does similar things (swiping homescreens, moving the cursor when typing, etc) it's usually because the trackpad is dirty. I can't really think of why the digitizer (assuming it was properly replaced) would be causing that problem..
My buddy Bob had this happen to his Incredible too when he cracked his screen and had it replaced. He had it replaced 3x through Best Buy because each time it came back it would freak out like that. It turns out that something inside the phone was shorting out to the chassis, it would only happen when he squeezed/held the side of the phone. They ended up just giving him a new one after the third time.

Yeah im thinking it could be something shorting but no real way to test. But after many take apart's i seem to have got the screen to a point where it does it like all the time rendering the phone useless. i have put back on the original screen and am seeing if there are problems there. (i got a new plastic housing)

Yeah i have disconnected the track pad and tried that with no change. and i tried disconnecting the light bar for a try and it would not boot. but i only tried once and i could have messed something else up when i put it back together.
i will report back with how the stock screen does and i'm thinking that will confirm that its the replacement digitizers .
Well the stock digitizer is doing the same thing. So its someting on the board, but i have tried it on two different phones.
So im up for trying just about any suggestion at this point. I have 2 phone and 3 digitizes doing this.
Mine does the same thing. I replaced just the screen awhile back.
I thought it might be related to maybe an upgraded screen family and the kernel not supporting it or something..
Like this post:
http://forum.xda-developers.com/showpost.php?p=15132827&postcount=3626
I usually take off the back and then pull the battery and snap the case back on. Seems to fix the problem until I mess with the battery again.
Anyone know how to see what touchscreen version you have?
ok so i have 3 phones(boards) 3 digitizers. 2 phones are the same hardware version i believe, one isn't. and all three experience this problem. This is even with swapping around the digitizers. I'm thinking that somehow all of these share something similar. All i can think of is me putting them together.
Any idea on what they share?
Just wondering if you ever fixed the problem or got it figured out to some extent?
Same thing is happening on my phone ever since I replaced the screen/digitizer. Took it back apart and cleaned all the ribbon connections and the problem is still there. Thinking it might be a grounding issue possibly since it seems like it goes away (most the time) after I vigorously squeeze the bottom of the phone, by the trackpad and capacitive buttons. But it invariably comes back, and seems to be worse when plugged in to the charger for whatever reason.
Also, since you've also taken apart and reassembled your phone, have you had an issue with the trackpad not sitting flush with the screen? No matter how I reassemble everything, it seems like my trackpad is recessed now and it's even worse when I use the little rubber gasket that was on there originally...
I haven't been able to determine what the problem is, but mine seems exactly like yours. When charging I pretty much can't use my phone random touches everywhere, or it doesn't fully reconize my touch. I just took my INC all the way apart and cleaned everything connections and all. I read somewhere it could be a dirty optical pad so cleaned that good too. Just powered on *Fingers Crossed*

when you replaced it did you make sure you the ground straps where connected to the screw holes with nothing interfering? i pulled my LCD out of my screen on my dev phone because there was dust under the glass. after i put it all back together i was getting the same thing descried in the OP. so i took it apart and noticed that the thread lock used on the screws pealed off and on the ground straps. so i cleaned them up with Alcohol and a cotton swab. put it back together and haven't had it happen sense.

When you say ground straps, are you referring to the two tiny screws that are near the top of the actual screen (after you've taken of the red battery compartment thing and the board)? I remember there being these little metal mesh strips that were in those screw holes that I think I promptly lost after taking the screws out..

yes. after removing the board on the back of the LCD screen there are 2 straps on the top that ground the screen to the frame. the screws had blue thread lock on the bottom. sometimes it will come off when you remove them.
basically make the head of the screw is clean and the metal straps are clean to make a good enough ground.
EDIT:
if you lost the screws you can try to pick up an eye glass repair kit. the ones used for glasses. they have small phillip screws that might work. you can normally buy the kit at a $.99 store.
I was wondering what the screws were for since it didn't look like they were actually holding anything in.. I didn't lose the screws, just the grounding material, which were those metal mesh adhesive strips. Trying to think of what I may be able to replace that with, maybe just some aluminum foil or something? There has to be some better material, I'm just not thinking of it..

the straps fell off? (the straps are on the back and should be soldered to the drivers on the rear of the screen) i wouldn't recommend aluminum foil. try going to a store like radio shack or any do it your self electronic store and see if the can sell you some fine wire mesh.
Hm, I think we must be thinking of different things, cause these were just tiny little pieces of wires mesh that those screws held into place that were stuck to the metal on the back of the screen. Might have to open it up again and snap a picture or two to clarify if I can't find any other grounding issues, etc.

yea thats what im talking about. the 2 straps on top that are screwed in. they need to have a clean connection from the strap to the screw heads that it sits on after screwing them down.
Well I'll be damned, I think that was it! I "borrowed" a little bit of that wire mesh stuff from the back of the screen (it's holding down the screen's ribbon connector and covering other things) and put the screws back in holding little strips of the mesh down and stuck to the metal on the back of the screen. I haven't been using my phone much but the phantom touches and vibration haven't come back, crossing my fingers that it stays this way!
Thanks again synisterwolf, mashed your thanks button a bit
To the OP: I'd highly recommend making sure the screen is grounded properly with those two tiny screws towards the top of the screen.
Thanks for the info guys! Does anyone have a pic of this mesh stuff. I think my old screen had it, but the new screen does not..

I haven't been using my phone much but the phantom touches and vibration haven't come back, crossing my fingers that it stays this way!
Thanks again synisterwolf, mashed your thanks button a bit
To the OP: I'd highly recommend making sure the screen is grounded properly with those two tiny screws towards the top of the screen.

Broke my volume down button

hey guys
my volume down button is not working anymore. it works sometimes, but i have to push reeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeally hard
I just wanted to know if someone knows the solution
I've red this: http://forum.xda-developers.com/showthread.php?t=1304940 but I'm not sure if that's working with the desire
also, I just wanted to know if there is a way to maybe change the button, as the volume up button works really fine
another solution could be spraying insinde this??

or the WD40

same problem here. would be great to know if there is a solution.
im not sure but there is probably a guide to cleaning buttons somewhere on xda r youtube etc etc. personaly i would NOT use wd40 on my phone as it probably would do more damage, i mean i use wd40 on my car engine. it looks like a hardware issue so i would try cleaning around the buttons etc, following a good guide

I had this problem then i took my phone to HTC service center for replacement. It happened in the last month of my warrenty period.
They replaced with new board related to volume keys.

There's a video on youtube how to disassemble the Desire. It's on German, but you see what you have to do: http://www.youtube.com/watch?v=FWkTYvSk9Ys
I'd recommend to open the device and look if you can repair something from within.
I had this and it was pretty easy to fix.
Dissemble your phone until you can access the volume buttons, carefully peal back the black plastic that surrounds them and then clean the silver domes and contacts with isopropyl alcohol or similar on a q-tip. If the domes are cracked or split then you'll ideally need to replace them. Once everything is clean and dry, reapply the tape and reassemble.
This made mine more reliable and easy to press than when I first got the phone!

how do I disassemble it?
last time I disassembled a phone all the dust got under the screen and it was worse than the worst awful phone...
It's pretty simple and you should be able to find a few guides on google.
As for dust under your screen, iirc you shouldn't need to remove the lcd from the phone to do this so it's a non issue.
http://www.formymobile.co.uk/desiredisassembly.php seems good enough for this, stop when you can (carefully) flip out the buttons or if you want easier access, when the pcb/circuit board is out. In terms of phones to take apart the desire is very easy
