odd touchscreen problem - 8525, TyTN, MDA Vario II, JasJam General

When I have my screen shut, and I use the touchscreen, the only places the screen will register taps is on the Start bar and the bottom bar with either Contacts or Calendar. If I open the screen a partial way or all the way open, my taps are registered correctly everywhere on the screen. Has anyone experienced this also and can I fix this problem other than having to always slide it partially to use the touchscreen?
Thanks

Well there are some possibilities that spring to mind.
Firsy there is no software involved in opening the keyboard just a lttle bit. (Iassume you are NOT opening it far enough to trigger landscape mode). If my assumption is correct then the magnet operated landscape switch is not invplved with this problem. That being the case, then I see two possibilities.
1. The flex cable that runs between the keyboard section and the main body is moved when the keyboard moves. Thus a loose flex cable connection is possible or worse a crack in a wire within the flex cable.
2. The pressures on the case and internal parts/connections varies a little between the closed position and with the keyboard out/partially out. The various connections you see in the picture below could be moving slightly when you partially open the keyboard. Prime candidates would be the D/pad connector with the two screws and the digitizer circuit.
Pic shows the flex cable and possible locations of loose connections.

There is one thing you can try (a remote possibility) and that is to ajust the torque on the visible screws at the back of the screen (when keyboard is open) Slackening a Little these screws is reported to help with some whitescreen and alignment issues and might just have some effevt. Other than that I see little option but to either send for repair or dismantle to check those connections and the flex cable for wiring integrity.

It's not immediately obvious how you would tighten the scroll wheel but I can check this weekend if you like?

Mine is getting pretty crappy lately, anyone know a reliable reseller that sells the scrollwheel assembly?

OK will have a look - possibly the black wheel just pushes onto a spindle, in which case it may just be slipping and could be glued or "packed" to tighten it, but we'll see.
Mike
Well unfortunately after taking apart and examining the jog dial / scroll wheel, it is rock solid on mine. I tried some leverage to see if it was a push on wheel but no joy. I have a feeling it may have a similar construction to old style volume wheels where there is a cir-clip on a spindle holding it in place. Unfortunately, ulike the volume dial set up where the spindle is accessible on the reverse side of the board - this one is not accessible without de-soldering the dial.
To de-solder this component would require the finest of skills. This is not a traditional board where the connections pass through the board and are soldered on the reverse side - it appears surface soldered (possibly multilayered) and surrounded by a number of likely heat sensitive components including the camera flash which is on the reverse side.
All in all I would suggest replacement new or second hand if you can find a source.
Mike
great...so where do i find the necessary tools to open up my device and replace the wheel assembly
anyone find a supplier for these scroll wheels?

Identify hardware inside Magician

Hello all,
I opened the Magician to repair the phone speaker, but also painting the housing. As I carefully document the parts I found one piece of hardware that draw my attention. I have a clue what it might be, but would like to share it, so maybe you know what it might be.
First some pictures

Location of the unknown hardware. When you hold your magician face up (screen up) it's under the red phone button.
piece we're talking about.
Where the 2 contact point on the unknown hardware connect to. Just like the phone speaker it kind of floats, so no wires..
As I watched carefully I noticed the shape of a half cylinder. By moving your PDA vertically/horizontally the heavy side moves towards where gravity is, meaning it always points down. (see picture 2)
I think it's some kind of hardware that suppose to, if a software supports it, turn your PDA display horizontal or vertical when you turn it. Something like iPhone demonstrated or even closer Wizard. Wizard's screen automatically goes in horizontal mode when the keypad is sliced out.
If this unknown hardware is what I think it is, why isn't used then? It would be a very nice feature
What do you think it is?
its your vibration motor.
ie: when you have 'vibrate' enabled, and your phone rings, that little motor spins like crazy and the uneven shape of the weight creats the vibration.
Yes, Definately that is the vibration motor.
Yeah... I forget Magician was a phone too... Since I don't use the phone I lost focus
Anyway... It would be great if it could have the ability to turn the screen auto. My guess would be that if that small motor could send it's position back to a chip it should be possible for software (OS for example) to act. (dual function)
I'm trying to fix my vibrator and your pics would help but the links no longer work.
Can you please relink or rehost them or send them to me?

hardware button problem; button 2

the internet explorer iconed button, on the top left hand corner; Button 2
is kinda playing up
It seems it is almost permanently pressed, though it doesn't seem stuck, when it is enabled the shortcut program or function continues to run; e.g. pie keeps starting (I've tried changing the shortcut and there's the same effect on any function I set to the button)
I've done a hard-reset, changed rom, but it persists, so its definitely a hardware fault. The main problem with it is, even if I minimize PIE for example, the hardware buttons remain unusable unless i unassign everything from that button.
I've tried cleaning where i can etc. but to no avail
its not a huge problem, heck it doesn't really matter if I need to keep that button without function, its just one of those little annoying and niggly problems, and maybe someone else has had the same and found a solution
if not its ok, and thank for reading

The above picture shows the two micro-switches (Silver blocks with round black protrusions). It would be well nigh impossible to dismantle these - replacement may be possible, though I suspect you would only be able to buy the board complete.
You say you have tried cleaning. Do you mean externally or internally. It may be possible that the micro switch is not releasing due to a detritus build up internally or some misalignment of the pasic facia switch cover. The micr-switches even when pressed via the facia plastic should give a discernable soft click when pressed.
Mike
firstly thank you very much, for all your effor, its well appreciated my friend.
I've tried cleaning externally only and yes it probably is a buildup of dirt internally, but I don't think I'll be dismantling the device as its only a small proble, and once I've removed the assigned function from that button its not problematic. But if it gets worse, starts again etc. I'll have to, so thanks very much.
Thank you.
No probs. Might just start working again by itself if the blockage gets dislodged.

Not so dead keyboard

I was at a party the other night and someone dripped water off the side of a beer can into my Hermes. It landed on the keyboard, I have inspected the board and cant see anything amiss (IE, it looks good)
but the keys behave erratically.
Heres a list of funky keys.
The left softkey presses the OK key.
The right softkey does the specified function twice so if its a menu it will appear then dissapear.
The "o" key types an "o" then presses the left arrow key(as in to go left a character)
The Windows key presses the right softkey with the same effect as the softkey.
The left arrow does the same as the "o" key.
The down arrow presses the "p" key and the down arrow so if its autocomplete
it will do it with a word beginning with "p".
The right arrow presses the return key.
Whats the best thing to do now?
I have checked all the connections and all seems OK
I dont really want to pull the white backing off the keydomes.
Anyone had any luck with keyboard repair?
Someome please show me the light as Im running out of things to think of
All the best and thanks in advance.
Mark
//Edit
Im running Schaps WM6.1 ROM
Second time I have ran it, went from Schaps to S64 WM 6.1 then back to Schaps ROM
Didnt have issues the first time but I have issues now,
I would like for someone to clarify for me if this is software or hardware?

Well i agree that peeling off the backing is a tricky business. You could trycleaning off the surface with pure slcohol or distilled water but the danger is that it may cause any contamination to seep in even further. You could try to identify any spots where penetration under the white layer has occurred and particularly any of the exposed contact areas (not covered by the white layer and clean those areas.
Otherwise it would be a case of removing the white layer:
Mike
Thanks for the prompt reply, just about to go shopping, will try this later and post the results
Thankyou Mike

Keyboard is failing :(

So after a year of heavy use, the keyboard on my g2 is starting to get kinda iffy. When I hit the spacebar, sometimes it puts in two spaces instead of one. Any way I can open it and clean/inspect the contacts?
Same here, spacebar puts often 2 spaces instead of 1, would be very interested in a fix.
send it to HTC
It's pretty easy to take the G2 apart (if you have some experience taking phones apart). Go to youtube and search for t-mobile g2 disassembly.
Here is a high quality picture guide.
Sent from my HTC Desire Z using xda premium
same here. I bought DZ in july 2011 and now the keyboard either does not write a letter or writes two of them (mostlly vowels) making hw keyboard a pretty slow method of input as I have to correct it everytime.
Did anyone of you already try to clean the keyboard? did it help?
Is the T5 torx screwdriver the only tool needed to clean the keyboard?
Thanks
I have this problem with my E key, but it's not consistent or annoying enough to bother fixing it. I haven't noticed it much lately, but it was pretty bad for a little while!
I also have this problem with my q, w, e and t keys :S. Except if i push firmly enough there are no problems, but when other people use my phone, they have a lot of trouble typing
I bought today a Torx T5 screwdriver, opened the phone, void waranty (again!, VOID sticker this time and got until the "Peel back the adhesive tab" step in the guide. After that only mainboard and display is disassembled in the guide.
The mainboard was disconnected from all the cables (microsd, touchscreen, display).
Unfortunately, I did not find a way to open the keyboard to clean it. Did I miss something important?
