My HTC Prophet's DPad has partially stopped working.
First of the UP stopped working, then several hours later the LEFT key didnt respond. Ive tryed cleaning the DPad and a soft reset to no avail.
When i leave the phone after 5 seconds it acts a if the left direction is being pressed and held. This action stops when i press the right or down key.
Anyone know what may be going on?
Back up your info then try hard reset.
It sounds like a hardware problem, but thats the only way to be sure.
Unfortunately if this is a hardware fault the only solution would be to take it to the lab.
Moving to prophet section.
Tryed HR, no avail.
Im pretty sure its hardware issue. There is grass stuck inside the casing which is impossible to reach. Everynow and again a small piece falls out.
Since yesterday im now able to scroll left. So i can only not scroll up now. Ill have to drive over some cobbles with the phone in the cradle to try dislodge some more.

How could that happen to me?
Two days ago there was a heavy rain shower and I left my beloved wizard in the outside pocket of my laptop case. I didn't realized that the rain was so heavy that the wizard got wet :evil: When I took it out of the pocket the keyboard and the speaker were really wet. So I took out the battery, let it dry for some time and the good news is that it is starting up and running perfectly at first sight.
But now comes the strange & sad part
The conn manager key (key 5), the left softkey and the internet key (upper right key) are showing REALLY strange behavior. When I press them eighter the right softkey menu opens up (contacts, mail context menu, ect.) or it jumps to voice dial (normally key 4). That happens with all the three keys!
I thought it might be some dirt left by the water inside the wizard, so I opend it for cleaning (did that before, so I know what I was doing ), but everything looks all right and no sign of a water "damage". I noticed another strange thing during the tests: When I press one of the three keys the keyboard lights are turned on :?: That's not normal, or?! They aren't lighting up when pressing for example the camera key.
Really strange, does anyone has a good idea what might have gone wrong? Or does one of our experts has a tip how to fix it or what might be the cause?
Any help would be fine, because I would like to try to avoid to buy a Hermes for some more time :?
Thanks in advance,
Jago
P.S.: I just found out that the keyboard left and right softkey aren't working the way they should eighter. But all other keys seem to work like they should...

it's probably because the water shorted out those keys. I've spilled water on my PC's keyboard before and all the keys got garbled. Y's because O's and T's became S's. It seems to me like the same sort of thing.
You will need to let it completely dry out. I'm not sure if you problem will slowly go away or not if you keep using it, but the surefire way to fix a wet wizard is to let it sit someplace warm with the battery out for 3 weeks.....
Hi XDA.
One day my "down directional button" stoped working correctly. When pressed nothing happens, however the up, left and right buttons work as do all the other buttons and functions on the wizard.
And sometimes the wizard thinks the down button is pressed so it starts scrolling down even though the button isn't pressed.
I have reflashed a few times and dissasembled the whole wizard with no visible errors.
Does anyone have any idea to what i can do to get it to work again? Please help me as it is now blocking incomming calls and does other crap.
Hi Mate
I have the same situation but on the right key. Upto now didn't find any solution. Driving me nuts. When I receive an sms late at night it ends up wasting all the battery . . . .
Hope someone comes up with a solution.
The lcd/digitalizer, mail/internet/led/speaker-board and yes/no/softkeys/d-pad/enter-board are all leaded together. so one can't just change one of the parts in the top sliding half of the phone. but there is a connector between the halfs, so if you have an other wizard that is broken you can combine the two.
but i only have one wizard =(
I'm having a strange problem with the hard and soft buttons on my phone.
I went to the park to take the kids to the pool yesterday. No, I didn't get within 100 feet of the pool with my phone. It was not placed anywhere wet and no one, as far as I can tell, got close enough to drip on it. It acts like it got water inside, but unless it somehow condensed from the air or from sweaty hands, I don't know how that could have occurred.
Anyways, I had set my phone up and when I picked it back up, it was like I kept pressing the messaging and IE buttons. Eventually letter keys on the keyboard like Q and E kept appearing as well. Every now and then it would work fine for a few minutes and then start up again. After leaving the phone out in the direct sun for awhile, it stopped doing that even as much but some of the keyboard keys and most of the soft keys seem not to want to work at all, neither do the two phone keys or the directional pad. Pressing the middle button on the directional pad causes the alignment screen to come up (???).
Making matters more confusing is the fact that on a couple of occasions when I did a soft reset the buttons would seem to function normally for a time. Most recently it happened last night when I went out to lunch. I had reset my phone and all of the buttons seemed to work fine again for several minutes. I got back from lunch and proceeded to browse the forums here. When I went back to my phone a bit later and had to wake it from standby, the issues returned. I have since flashed to a new ROM but have experienced no change in the symptoms and have not gotten the buttons to work with a reset since, though I've admittedly only tried a couple of times. When I tried doing a hard reset, it instead went to the bootloader screen.
So, yeah, I'm confused. It acts like it got moisture in it but I don't know how that could have happened unless it was just from my hand. In any case, trying to dry it doesn't seem to have helped. Does anybody have any ideas on this or am I buried? It's several months still before I can upgrade to a new phone at a discount with my provider and I really don't have the money to do so in any case. I can use the touch screen but, let's face it, the WM interface is a lot easier to navigate sometimes with the buttons. I'm holding out big hope for the WNAIP project to succeed here though. Of course, that's not to mention I can't play games like Tetris without a working directional pad.
Okay, it's pretty much gotten to the point where none of the physical buttons works, hard or soft, and even some of the kb buttons don't work.
Anyone?
My M700 (orange rom, new radio rom) is having problems with the buttons (or is it?)
Basically, I noticed things were happening without me pressing buttons, occasionally (like when Im in a phone call) it will flash up that I cannot put this call on hold (though I didnt try to)- or when I'm in GPS (TomTom) it occasionally goes back to the options screen without me pressing anything.
I also noticed that occasionally the scroll wheel wont work on the side, and if i press the memo button opposite, it goes to the "realign my screen" program (which happens when you press them both together) but then it works normally again
Finally the little directional pad at the bottom has stopped working sometimes (including the button in the middle, but not the buttons surrounding them ie ok, windows hang up, make a call etc) -
Anyway - it seems to me like either there is a software problem, or that one of the buttons is being activated continuously, possibly by dirt, which might explain the intermittent nature of the fault.
Does anybody have any similar experience?
And...
What should I do - look at potential software problems, or hardware - (Im thinking hardware) should I take it to bits and clean it?
Thanks for reading my lengthy post, and I really appreciate any help from anyone, especially from people who've had this problem and fixed it
Update (2 mins later)
Whilst examining my pda, I dropped it onto the floor, and everything started working again - I'm beginning to think that its the silver button in the middle of the direction pad that is causing the fault, as when I hold it on it has all the same effects -
So, if this is the case, does anyone have any ideas, how to clean it easily? (if it is a hardware problem that is- it lives in my pocket and get pretty dusty so it could be)
Hello, I have had this TYTN I for a long time without any major problems. It was originally with WM5 but then I upgraded to WM6. Lately I had a strange problem whereby the front buttons stop responding intermittently.
The below mentioned buttons stop working:
1. The Internet Explorer button.(Above on the right)
2. The Message button.(Above on the left)
3. The Call buttons. (The call picking and disconnecting button, below left and right) And the 4 keys along it.
During this time I have to resort to the pointer or the side wheel to use the phone, which is very frustrating.
If I press the reset button at the bottom, the keys work again for a few times, then stop to respond again.
I have tried to flash again with both WM5 and WM6 but did not help. I have opened the phone and reseated all connectors but did not help either. Do you think I should try replacing the ribbon cable?
I have searched the forum and found several threads with the same problem, but never a solution.
Your help is much appreciated. Thanks.
I have been struggling the last few months with the same exact problem. Sometimes the buttons work other times they don't, and in the last couple of weeks the frequency of button failure has increased (every couple of minutes).
I found a few users yesterday over on the HTC forum who were having the same problem and 1 user who actually reported a fix that worked for him.
Go to Start/Settings/System/Key Lock and select "Do Not Lock Buttons". Exit Key Lock and soft reset your device. You may know return to the Key Lock options and re-select your choice (I used "Lock all buttons except Power button").
Worked for the HTC user and is working for me as I have had no button failure now in the last 24-hours with repeated use of the device.
I hope this works for you because if you are like me I getting very close to trashing the unit.
Hi,
the problem could be the Xilinx chip (a BGA chip) on the pcb underneath the buttons.
As the buttons are pressed the board is flexed and some of the solder pads under the xilinx chip must have become detached from the xilinx chip itself.
I had the white screen problem. An while i got the white screen the front buttons where not working too.
In the whte screen threat i found that it could be the Xilinx chip, and figured out when pressing on this chip the white screen was gone and the buttons where working.
So i resoldered (refloated) the chip with a heatgun and some liquid flux last Sunday and since then i had no problems anymore.
I would suggest disassembling the phone down to the pcb and try starting it on with the ribboncables connected while keep some pressure on the Xilinx chip. And then trying the buttons if they work.

I have the same problem with the same phone. The instructions above for "key lock" didn't fix it for me. I was assuming that it was hardware; but I just tried installing the Android port for this phone and under Android the buttons work fine.
I know that Android has some good stuff going for it, but I don't think it's awesome enough to circumvent a bad circuit... How exactly do these buttons work? Is there a process that should be running to handle them? Any other pointers?
