strange keyboard problem - 8125, K-JAM, P4300, MDA Vario General

I experienced something strange with my Qtek 9100 today. when i turned on my phone, all the keys including the call and the 'hang up'-button where backlighted. the keys did not respond as they should, and pressing the d-pad center would either open the start menu or initialize the screen calibration. if i opened the Notes app and created a new note, the note was filled with single letters like the L, the H or the Y. none of the keys seemed to be working when i pressed them.
i've experienced this once before, and the only thing in common is that i had my phone in a thight pocket for several hours. last thime i solved the problem by hibernate the unit and pressing all the keys, and turn it on again. this time it wasn't that easy, but i managed to get it working again at last.
but why is this happending?
PS: i've tried soft reset and taking out the battery, and that didn't help.
Please help me and my phone

buttons problem in P3600

Hi All,
I have a strange problem, tried to search the forum,
without success...
Sometimes the OK button doesn't response (both OK buttons...),
only clicking OK on the screen works.
another issue - sometimes when clicking the action button nothing happens, or even worse - it acts like a long press even when I press it really shortly...
Any one else had such problems?
Is it (as I guess) a hardware problem?
I have the same problem and I dont think its the hardware cause the button is not presented in "buttonmapping" in the controlpanel. This has worked before. Please respond if you solve the problem.
Mine does it on occasion. Pretty sure it's software and It seems to happen with the same apps each time. Make note of what apps you have running when it happens.
Just started doing it again but I realized that I have never had a prob with the OK or Start Menu buttons but rather the softkeys. In Today Agenda, the left key (edit) stopped working and then a few minutes later the right key (menu) stopped working. I closed all apps and the problem persisted with every appointment I opened. Soft reset fixed it.
I should also add that I am not using the latest version of Today Agenda because I have not figured out how to make it look like the version I am used to.
Might be related: a lot of games I have tried don't seem to support the softbuttons, phone buttons, or really much else besides the directional pad and center select button.

hard and soft buttons intermittently working?

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?

Has anyone solved front buttons not responding problem?

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?

T-Mobile MDA/Wizard Malfunctioning?

Hello there, I am quite new to this forum, only being a lurker for quite some time. But I have decided to join because I am in dire need of help. My MDA/Wizard has suddenly gone out of control. I have had Mobile 6.1 installed on it for years with no problem, and the .cabs I have are working fine.
Now, recently, my phone has acted in a very unfavorable manner that has even caused me to hard reset it to it's original state, with still no luck. On about three different occasions, my phone's lights, keyboard and face, have gone off, and stay on until the phone locks. The main buttons, (Directional arrows, Exit, Call, Internet Explorer, and Mail) do not function unless I press a top right hand corner button on the keyboard twice. From there, it slightly functions. When I quickly press the power button and press it again, the phone will enter its mail area. Doing this again opens up internet explorer. Pressing the center button in the directional pad causes the screen adjustment function to suddenly appear. The keyboard can barely function.
I have no idea what's causing this, any help please?
try getting the newest hard spl and flashing a new rom. maybe your rom got corrupted

[Q] Touchscreen works only until screen is turned off for first time

Hello all,
I have a problem with my HD2's touchscreen. I've had the phone for awhile now and never had any problems. I've been using android from Sd for awhie and recently switched to NAND android.
I go to bed with a working phone and when I wake up, the touchscreen doesn't work. After trying to use it all day, it occasionly works. When I receive a call or text, the screen works just fine. I am abe to use it until the screen turns off then no more. This happens for each call or text. It also works just fine at first boot(until the screen is turned off.
Thinking that this was a software problem, I tried flashing different android builds, with the EXACT same results. I then wondered if it was a problem with MAGLDER, so I flashed back to a STOCK TMOUS rom, and stock SP, radio etc.
Even after going back to COMPLETELY stock, it now does the same thing in WINMO. Works just find at first boot until screen goes off, and works when I get calls and texts.
I'm now thinking that this is a hardware/digitizer problem, it just seems weird to me that it works 100% until the screen goes off and then not at all.
Anybody have any idea's or insights?
Thanks!
i've read a few similar threads (please search for them!) that indicate one possible cause...
your buttons strips at the bottom may be messing with the touch screen connections. i remember reading in one thread that the dude found a strong relationship between use of the on/off/endcall button and touchscreen failures.
you say it works...:
1. ...until the screen powers off
2. also works when you get an sms or call
in case (1), you have to press the endcall button to "wake" the device...so maybe the button puts just enough pressure to screw up the screen.
in case (2), the device wakes up automatically, so you never pressed the button that might cause the screen to screw up.
try to narrow it down like i've described. maybe your buttons are causing the problem. good luck!
Thanks for replying!
I did see the thread you were talking about though it did not seem to match my problems. However, today as I was working and pulling my phone out, It has started to look like that is the case. As of this afternoon, as long as I press any of the buttons other then the power/end call button to turn on the screen, the tuchscreen works just fine. When waking up the screen with the power/end call button, it does not work at all.
Yesterday and this morning, it didn't matter what button I pushed to wake up the screen, it was totally unresponsive.
So it looks like using the power/end cal button presses on my digitizer and causes problems.
And it's back to not working at all when I use any of the buttons, lol. Guess it's time to start looking into a new digitizer.
