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?

Hi guys, hoping someone can give me a hand with this.
Nothing has happened in terms of traumatic force that would damage the phone.
ie: drop, get wet etc.
It has started to open any of the programs i attach to the top 2 soft keys, and the key pad and phone buttons no longer work. I can x out the programs as they open but they rapidly open again.
It will also have functioning moments where they keys work and everything is fine
wtf?
P.s. i tried reinstalling the ROM update from the HTC site and it had no effect.
Just to be clear, the programs assigned to the top two buttons (mail and internet) open on their own? If so, does this happen as soon as you turn the device on?
Hi there,
Sorry its hard to be exactly clear when I don't know what the problem is.
When I turn on the device those programs do open automatically. I had assigned the media player to one, and it would open automatically. Now that its been reset to the HTC site upgrade the outlook program opens automatically as well as internet explorer, over one another again and again.
I have now set no program to those buttons but the device is still not very functional.
The enter key in the center of the directional pad now either drops down the start menu or opens the screen calibration.
In fact all the data inputs are problematic.
Thanks for any help. These things cost too much to go over my balcony but every man has his limits.
Also we have the exact same machine, minus your ext.ROM and 260mhz.

the wizard is designed to open the screen calibration if you hold both the 'action' and 'mail' keys at the same time. with this in mind, it sounds like it thinks the 'mail' button is being constantly pressed. i don't know why this would be the case, but i would check; for dirt/dust build up under the buttons; broken buttons; and no odd software installed to startup folder?
Will do.
Thanks for the help.

That's my take on it as well. Both of the buttons appear to be depressed all the time. The left and right buttons are on one board called the rigid flex board. In my troubleshooting experience (F-16 fighters) I’ve seen that it’s highly unlikely both buttons would go mechanically bad at the same time, so I believe it may be a bad board or a loose connection between the rigid flex board and the main board. If your device is still under warrantee then you may have to send it back for work. If it’s not under warrantee and you feel comfortable with disassembling your wizard (Google search HTC wizard service manual for step-by-step directions) you may want to look at the connection between the rigid flex board and the main board. You may also be able to get a replacement rigid flex board from a few people on this site that have spare parts.
Just my thoughts,
Thanks guys I appreciate the help. I guess I'll try and take it apart. I don't think it'll be a very cost effective solution to ship it to HTC for repairs, probably will end costing the same as replacing it.
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.
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)
It first started with the blue light blinking, even with the phone turned off. The only way to stop it from blinking was to remove the battery for about 10 seconds.
Then, everything I typed staarted to ddoublle letteers raandomlyy.
Now, it's acting like the down button is stuck. I can't do anything on the phone because its always scrolling down, beating out any other input.
I can live with the first two, but the third one has made the phone completely unusable. It's never been around water, never dropped, just randomly doing this crap. Any ideas on how to fix it? Hard reset does not work, new rom does not work, its a hardware issue.
Yes it is probably a hardware issue. Time for a phone swap
I'm actually out of warranty, so the only thing I can do it either switch to a different phone or try fixing this one. Have nothing to lose by opening it up, just wanted to see if anyone else has fixed it by cutting any wires or connections on the inside of the phone.
You don't have insurance

No phone insurance. Verizon completely screwed me on that phone purchase in more ways than one. By the time I figured that out it was to late.
TO bad I got mine added late. I just called the lady I bought the phone from and she added it.
Not sure about the blue-light.
I was able to fix my repeating-letters using the keyboard fix in this post:
For the constant-down input - it could either be the touchscreen digitizer or the hardware keyboard. YouTube has a series of videos on dismantling the Mogul - it may be worth some "exploratory surgery" to see what might be causing the problem (cookie crumbs, perhaps)...
Hope this helps. Good luck.
Htc mogul hardware button - issue
Dear XDA GURUS,
I am facing this very weird problem on my HTC MOGUL. All my Hardware button have stopped responding / Working. Please help me sort out this issue.
Waiting for your valued reply with solution.
Detail given on below link.
My HTC MOGUL HARDWARE Button Issue
Dear XDA GURUS,
yesterday i tried to do some RnD for this same problem. now the inputs. (Nothing technical)
* Even though my camera hardware button is not working, but, i can still enter the bootloader screen.
* Even though my both soft reset hardware button are not working, but, still i can do the hard reset.
This only means that, my buttons are working fine, but, according to my logic, they have lost there assignment.
After that i started searching web, if i can find a App / setting / hack / register setting, in which i can assign then there original key setting. So i found this on XDA forum as below.
Code:
[B]How to assign a shortcut to EndKey, SendKey, Power Button, PTT Button!![/B]
Hello
Since some of you guys asked about this , well there you go:
if you look inside the keyboard driver with a good disassembler (IDA Pro) you would see that you can create these link files :
Long_PTT.lnk (push to talk button+long press)
Long_End.lnk (the read key+long press)
Long_Send.lnk (the green key+long press)
Short_PTT.lnk (push to talk button)
Long_Power.lnk (Power button +long press)
Short_Power.lnk (Power button)
So basically all you need is to create these link files and put them in to windows folder. You can assign these keys to any shortcut you want .

ok now, certain things are clear. now anybody out there can help get this thing sorted out.
Waiting for concrete solution.
Since two days I have strange behavior of my Blackstone touchscreen.
Just after start (or reboot) it works correctly but after few minutes when I hit for example start button it actually point about 1,5cm upper. So all touches has offset and hits not in the correct place like this:
Hit spot

Touched place
If I mange to go setup->screen->Align screen it's fine for a while and again after few minutes it's happen again.
ROM is Energy.BLACKSTONE.23149.Sense2.5.Cookie.2.0.Dec.01
Do anyone have the same issue?
It's more software or hardware problem?
At least yours still works... I also got problems with touch offset and decided to change the digitizer... but broke the lcd screen during the operation...
My device was acting just like yours: after screen alignment it worked for couple minutes then just went crazy... unfortunately, it's a hardware problem (problems between the first and the 2nd layer of the digitizer).
To align the screen more convenient just do this at any moment (with the phone switched on):
Press VOL UP and VOL DOWN simultaneously and while keeping them pressed, lightly touch the screen. This will surprisingly initiate the screen alignment procedure.
Hard reset?
