Keypad + screen issues (after reassembling)

I took apart my tytn, including the screen part.
After reassembling it, I've had random issues related to the keypad and screen.
By keypad, I mean all the keys on the screen part of the phone (D-pad, call/hangup,soft left/right, Internet Explorer & Email).
They will randomly cease working and randomly restart working (usually after turn on/off the screen with the power button)
The screen will also randomly turn white and come back on only if I turn off the screen and then back on.
Im thinking it has to do with a loose connection somewhere in the screen section of the phone, however, Ive taken it apart 2 more times to check everything out and the problem persists.
I wonder if anyone experienced the same thing and found which specific internal is the issue.

i would like to know too cause my buttons just stopped working. so the talk, end, message, Internet explorer, ect. but the left down up right and center button work.

I have the exact same issue.
All the keys (not keybord keys) randomly stops working. I am so used to it now, that I dont even try to answer the phone with the green key button.
The screen fades to white, sometimes (maybe 1-3 times a day).
The screen is white when awakening from "sleep mode", turning on and off the screen fixes that after a while (50% of the time white screen when from sleep mode).
I have found out that putting a finger nail between the keyboard and the screen, on the right hand side, when in closed position, and then putting the screen back on, gives me a 99% chance of funktional display.
The problem also accurs in the "full keyboard position", But putting the finger nail in the same spot helps.
So I think the problem of the connection is in the keyboard part of the phone, since those slide contact always are on the right hand side, and the display contact shift side.
I would lite to know if any body have a permanent solution for this.
(I have now opend my phone yet, and I have tryed the putting thin plastic between the display and the cover, with minimal success)
thanks for your time

These are the exact symptoms of the "SCREEN FADING INTO WHITE" problem. See this thread for more info: http://forum.xda-developers.com/showthread.php?t=303872
The common causes for this are a bad connection to the D-PAD controller PCB (in the technical manual they mention it should be carefully checked and the really small screews with same torque making a 90 degree with the PCB), a bad controller (that was my case, had to order a new one) or not enough pressure on the square black chip on controller (some people seem to have fixed it by putting a plastic sheet in between the chip and the case, to apply constant pressure).
I suggest you try to re-open your phone and reconnect the D-PAD PCB as carefully as you can, double checking the connection and the screws there.
I did fix my problem, by ordering a new PCB and replacing the old (probably bad) one. It started to happen after I dropped my phone and it's the only thing that worked. Now my phone is as good as new.
Hope this helps!

Similar Issues with screen
I have similar issues;
Anything thats on the foreground gets closed by the 'x' button and if I slide it open the start button gets continually pressed!
Seems to be the top right corner of my TS thats at fault
sometimes it's fine....most of the time its not!
Andy.

I have the same! I have a huge dead spot in the middle of my (Tytn) screen, and if you tap there it actually activates the "ok" in the top right corner. The rest of the screen works ok. Whilst drawing in notes any drawing near the center dead spot results in a streak to the top right hand corner...
Bad screen?
Bad rom?
Bad motherboard?

You can rule out the ROM and M/board in my view for this specific problem. Your issue is very similar (and I think has the same cause) as those who find programs close randomly when in portrait mode and when they open the keyboard the start menu often pops up untapped.
I think this is just a case of a bit of pressure being put on the screen top right corner. Some folks have tried the business card run around under the bezel fix and had some success others have had to return for replacement/repair.
Some have taken the device apart and removed the gasket around the screen under the bezel, but this is not guaranteed to work.
Others have replaced the screen and for this particular problem it is very rarely successful as the screen is not normally damaged.
If you have a warranty use it - all of the above "fixes" are warranty voiding.

Hi Mike
It's an interesting problem as when performing a click and drag in Notes (drawing mode) the center section of the screen seems to work normally - a square box can select an area right through the middle of the screen - suggesting that the screen (as you say) is OK. So what is causing the a tap in the middle of the screen to register in the top right hand corner, when we now know that the center of the screen can work and respond in the correct manner. The size of the affected area is about the size of a thumb print EXACTLY in the middle. Personally I would like to believe that performing screen alignment 4 - 5 times a day for the past year has worn out the center dot and that is affecting the surrounding area. The trouble is that this fault has been reported on this site a few times now, and everyone says it's caused by something else! What did I do immediately before this happen I hear you ask? I flashed a new radio rom and was fiddling with a piece of card I have wedged down the RHS side of the screen to try and help stabilise the screen alignment. Since this problem arouse, I have removed the gasket - but that hasn't fixed it. I'm going to try and boot up the phone out of the casing to see what "zero" pressure applied to the screen does.
I'll report back...

It will be interesting to see what results you get. You'll need the old rubber band technique to hold the battery in place while you do it!

Well it's not due to the case squishing the sides of the screen as I just dismantled my hermes, wired it all up in bits on my desk, powered it up and still the screen has a dead spot in the middle and phantom taps in the top right. Temperature is normal room temp, approx 22deg c today.
I'm not sure the exact mechanisms of how these touch screens work out where you are tapping (resistance, voltage), but it looks like there are 3 separate strips running around the screen. 1 goes straight across the bottom, two goes up the LHS and across the top and 3 goes up the RHS. Therefore there is a gap between strips 2 and 3 in the top RH corner. Coincidence? hmmm It seems to me for it to register a tap in the top RH corner, strips 2 and 3 would register low voltages (or high resistance) and bottom wouldn't register at all. Thus suggesting a fault with the PSU that powers the touchscreen. Taps near the edges work because they are near the edges and therefore the resistance is not too great and can be detected, taps in the middle and worse off because they are far from all the detecting edge strips.
Does anyone think that there might a registry tweak for boasting power to the touchscreen?

Hermes Whie Screen Problem
To fix the "white screen" problem, you have to take your unit apart, and reconnect the ribbon cable.
I have a new 8525 and it started happeneing to me, so I took it apart this week, and reseated the ribbon connector.
Fixed the problem.

Has anyone here read and understood all that is said here:
http://msdn2.microsoft.com/en-US/library/aa919680.aspx

Perhaps someone could compare the touch.dll in Black Majik to WM5 - should be the same right?
How come that HKLM/hardware/devicemap/touch doesn't show the touch.dll driver as drivername? Keyboard has it's driver...microsoft says it should say drivername = touch.dll
Do you all have that in your registry?

Touch screen / KB doesn't work properly when Hero horizontal.

Hi Guys,
Has anyone else noticed this problem? and / or Could you please test this too to see if it's a common issue?
I use the "phone keypad" style, to enter text as I find i'm the most efficient with that one. However when the phone is horizontal, on a table for example, the backspace key just does not respond. (Which is on the right hand side of the screen near the edge)
As soon as I pick it up, so the phone is at a 45 degree angle for example, the backspace "key" responds again.
In summary I have noticed the left and right areas of the screen do not appear to be very responsive / don't work when the phone is horizontal. The middle "keys" / area is fine.
Any ideas / anyone else?
Had it for a few weeks now, not dropped it or anything, and everything else seems great. What's the deal with replacements from Orange if necessary, do they have to "repair" it? (EEK!)
Cheers, Si

I think you are experiencing this http://forum.xda-developers.com/showthread.php?p=4340678#post4340678
It seems to be more about whether your fingers are touching the bezel!

Rather than pick up the phone, just hold it using the thumb and forefinger and see if it works correctly. It seems to me that the touchscreen definitely works better so long as you're physically touching the device elsewhere than just using the screen. I do wonder if this is an artifact of the capacitive touch screen - I'd be interested to know if iPhones show the same behaviour.

Weird Touchscreen behavour - Video Doku.

Hi, I'm a big fan of the HD2 but in the last two weeks, since i own this device, i'm getting confused by some screen imput behavour that i will present you.
I want to figure out if this "screenbugs" i have to fight with every day, are normal or a hardwaredefect. To make you guys an imagine of what i mean, i uploaded some youtube videos for each bug.
1. The first one i call: The painting edge
This bug is only present if i not have installed the less sensitive CAB from this forum.
Explaination:
Many of you have notice that the glass of the screen doesn't fit exactly in the case of the device. The right bottom of the glass protrude a very little. Then i lightly press on this position, the screen notice a press on the right top...as you can see in notes on my youtube video:
Video 1: http://www.youtube.com/watch?v=c49x9vB4bzQ
------------------------------------------------------------------------
Beforce you say...my device doesn't having any of the following bugs, REMEMBER, This bugs are not present every second. Sometimes i can use the device for 30min without having some of this.
------------------------------------------------------------------------
2. The Electrocardiography
This bug, i think could be the reason for the following bugs.
Explaination: Trying to draw a straight line an you think you device will get a heart attack soon.
On the half of my second try you can see how the device suddenly works normal again.
Video: http://www.youtube.com/watch?v=t54m1dSLnV8
3. The shaking Screen
Explaination:
I have notice that some other guys have this bug too. You can see this on every scrollable screen, like opera, IE, zoomed pictures, the manila tab, startmenu...etc. etc.
Best seen on minute 0:54 in my video.
Video: http://www.youtube.com/watch?v=6hIE_wV4djs
4.The non pressed key
Explaination:
You are cofused about keyboard reaction while writing a text message? You type an "a" and getting a "t"? Than you have "the non pressed key" bug how i call it.
you have to watch on some key input where my finger is totally out of range. I don't mean the fault input next to the key i pressed...
Video: http://www.youtube.com/watch?v=_B1GiyMp_O4
----------------------------------------------------------------
There is a fifth bug i didn't get on video yet because it is very rarely.
I had have this bug only 5-6 times since i own this device, but it sucks realy hard.
I call it
5. The self-typing keyboard
Explaination:
Then i'm typing some text sometimes the keyboard begins to typing without having the finger one the touchscreen. it can be have a duration of 5-10 seconds or 20 letters/numbers.
It can also be watched, without keyboardaction. Then the screen scrolls wild in any direction without any finger on screen.
Video: http://www.youtube.com/watch?v=-fdXU8SoPTg from htcracer211
----------------------------------------------------------------
If someone can tell me if i can embed the youtube videos in this forum...

Go get a replacement, the screen is perfect. Although I admit it does not fit correctly but it is great. I only need the earpiece fix

please watch the videos before you comment anything...

...You're too much electrostatically charged...
...Or something of electrostatic is in the range of your device...
But it's like your touch panel is faulty. Get a replacement (warranty rules)

Have brought it back today...but couldn't get a replacement...no devices

tryed all your test and get no errors on screen, electro worked perfecly, keyboard keeps presing same key without leaving the range, and i cant notice any shaking effect.
So probably your screen is faulty , change your device as fast as you can matte

I have brought it already back, but it seems to be that others have all my listed bugs too. take a look at the poll results. On another forum a guy has tested the "painting edge" on 3 devices after he saw my video and all devices have this bug!!!!

Hey Guys,
I have the first 3 bugs on my HD2, too. But with BSB Tweaks 1.31 i solved the first 2 one by activating the option "Screen Sensitivity".

Hi,
If you look in the sticky thread here somewhere in the LEO section about tweaks and registry changes there is a topic on reducing the sensitivity of the screen.
I think what's happening here is the electric current in your fingers is playing havoc with the screen when your fingers are either close to or on the screen.
Let us know if this helps you.
WB

whow, that's a lot of problems for one device.
I have the "non pressed key issue" : (that's annoying as hell, typing a message is a heavy burden now) and the shakey screen. should i bring my handset back or try the tweaks... I didn't expect this from an 600€ handset

When i was made this video my finger was always with the same pressure on the touchscreen. It was not close...and not weak on screen...normal pressure. And you can see at the middle of my second try where i'm drawing lines in notes that the screen suddenly works normal.
I also wrote in my first thread, that this bug is not every second present...but then it's present its also the reason for some other input errors, like the "non pressed key" i think.

Quick question: How much pressure do you apply to the display (what is "normal"?)? Scince your display is reacting weird to pressure on the bottom right corner, any pressure might be linked to erroreous behavior. Do the shaking related errors remain when you don't press at allk?

to the OP: what ROM are you on ? have you tried 1.48 ?

I can recommende you to use screenprotector film and install cab for less sensitive.
But even without this all I had not this problem Looks like your sreen very sensitive for electrocharging and not have normal ground contact. This is way to warranty service.

lmao >.< sorry mate but get a replacement NOW!! I've never got these problems, everything works smooth and properly, sorry about that...

do u have a screen protector? i am wondering if the screen protector does anything bad to it...

You have the exact same problems I had when I first got my device, the main concern was the device having its own mind and making random key presses, even without you touching it or even being near it. I got my unit replaced and the new one works like a charm.

I noticed today that MY PERFECT SCREEN starting acting weird !!!! Its jittering !!! Damnnnn !!!!

I'm totally spooked by your video's!!!
I personally never experienced these bugs so I spend the last half our replicating your bugs.
The only thing I noticed was that Electrocardiography but I think you have your finger too flat on the screen (it has a too large surface area) because when I write on the screen as if my finger where a pencil (straight up instead of flat) the screen is working as it should!
I think you must have a faulty device. Perhaps try to flash it with 1.48 if you haven't done that already.

On iPhone with exactly the same finger it draws almost a precise straight line. This problem comes directly from HD2's screen, not from fingers, weather, humidity and so on.

Is there a way to calibrate ?

Hi.
Recently I Purchase Used HTC Hero. Upgrade from Jasjam...
Still new to Android...
In the Edges of the screen, such as 'Q' letter on keyboard, Sometimes the ADDRESS Bar, sometimes it does not read my finger, I need to lay my finger for few seconds, or move my finger toward the center of the screen, then it reads my finger.
It looks like a calibration, and/or sensitivity issue...
is there a way to calibrate the screen, and sensitivity ?
or maybe the HERO has some hardware issues ?
Thanks
Oren

you can re-calibrate they keyboard from the settings, can't remember where but its probably under text input

[Q] Phantom touches screen issue

So I've been getting ghost or phantom touches on my phone for the past few weeks. I couldn't figure out what was causing it because I've never dropped my phone and it never got wet. The phantom touches only appears down the right side of the screen in almost a straight line. It doesn't happen all the time and I thought it was random but I got it to occur at a successful rate. If I press down on the top left corner of the screen, it would cause the phantom touches. When I press and hold down the top left corner of the phone, everything is fine and no phantom touches appear. I decided to tighten the screws on the top left and it seems to have made it a little better. I'd have to really tap on the top left of the screen to make the phantom touches appear again and it doesn't occur at a 100% rate but it's still occurs.
Anyone know what is causing this? I thought it would be a broken digitizer but it doesn't make sense that tightening the screws would cause the issue to almost fix itself. Problem with the geomangnet? I'm not sure what that does really.

Put 2 (or more) fingers on the screen of your Note 3 in a horizontal line in landscape mode. You can also use Portrait mode with 2 fingers.
Move the fingers slightly about, trying to have both (all) in a straight horizontal line.
After only a bit of trying one (or more) detected fingers should disappear (become undetected) or ghost touch detections should appear.

Thank you for the help and suggestion but I've already tried this. My touch screen is fine in terms of detection. I can put 10 fingers on the screen and it would recognize all 10 fingers. My issue has something to do with the top left corner of the screen affecting the right side of the screen. Like something is loose. When I clamp down on the left corner of the phone, everything works fine. No ghost touches (that sounds dirty) or any of the sort. When I let go of the top left corner, I will some times get ghost touches.

It's not a firmware issue. It's definitely a hardware issue since it starts tapping on buttons inside TWRP recovery. Ah well, I tighten the screws even more and it looks like the phantom touches are gone. Hopefully it stays that way even though I destroyed a screw in the process. Those tiny things are fragile.

if the touch ghost click is in some certain location most because of pollution (mainly chemical), best is use ISO alcohol also use a very tinny sharp blade, like a very thin one and slightly go along side the place that does this, sometimes you have to try both horizontal and vertical, then clean with ISO, do a few times it does alright. it does work on most of touch screen include note 3 as well.
