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!

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?

Cracked LCD or whitesreen?

I have read a few posts about the white screen issue and some seem to pertain to my problem and others don't. My screen is white 100% of the time from power on to power off. So I can't seen anything when it first boots or comes out of standby mode or any thing else. The only way that I can get the screen to be anything but white, is to hold it in my left hand with the keyboard slider bottom left corner of the phone pushed up against the base of my thumb muscle and my other fingers pushing on the bottom right corner or the phone on the screen slider. Sometimes if I hit it in the bottom right corner then squeeze it I can get it to work without tiring myself out from squeezing after 1 minute.
Seems to be a pressure and angle thing i think. The phone has been dropped on more than one occasion. Ten tops. Sometimes when I squeeze it i get lines from left to right, then fade to white.
If I put the phone on 65-90 degree angle from my eyes I can see a little black mark at the top of the screen under the C of HTC. That is what had me thinking that it was a cracked LCD.
Any help would be greatly appreciated. Phone is still under warranty, but would rather not be without it for the 6 -8 weeks I was told it would take, only to find out it was a cracked lcd and they won't fix it.

I believe you have to open it. Try to connect every single connection again.

I Had This
I had this problem when i dropped my Vario 2 the screen cracked and was all white, when i went on ebay and bought a new screen I took the vario 2 apart and replaced the screen BUT the ribon connector that plugs into the board was not quite in so when i re-assembled it i just got power and white screen.
There are a couple of little lugs on the ribon cable and i though that once they were butted up to the connector on the board that it was in properly. BUT the lugs actually needed to be pushed that little bit further and slide under part of the connector. BANG it worked fine.

Either send back and keep warranty or try the several solutions posted. I myself am pretty sure I found the correct solution and I posted it in the appropriate thread.

Thanks guys, I think I'm going to try my luck with sending it in. Will probably add a link to the main whitesrceen thread so hopefully I get no hassles. Will post back When I get it back.

I had a similar problem and voided my warranty because I don't have a spare device... anyway, here is where I found my solution.. http://forum.xda-developers.com/showthread.php?t=321163
Good Luck... My phone is still working fine....

Screen turning red on 8525?

Today I noticed that my 8525 has a weird red tint on the screen whenever I close the keyboard. On the right hand side of the screen, there is a line, and everything to the right of the line has a weird red tint. If I open th phone slowly, the line dissapears at the same rate that i'm opening the phone. It almost seems like something underneath the screen is... pushing on it from below or something? Just a guess. Also the screen's alignment pretty much doesn't work at all anymore, like its the curser will either be on all the way to the left, or all the way to the right. never where i am pushing. Quite annoying.
Thanks for any help!

Me Too!
The same exact thing is happening to my phone too. Sometimes when I slide it back and forth a lot it will dissapear but come back again later when I move the slider. It appears when the slider is slightly off of the closed postition. It never appears when it is open. I think it may have too do with the cable being loose between the main body and the upper screen part or the magnet which detects the slider postition is interfering with the LCD. Any solutions yet?

Is this normal?

I have just got my blackstone and I would like to hear from other owners if this is ok
1- I feel that something is loose beneath the camera, when I put my phone on the table or when I tap on the camera from the back I hear as if something is cracking
2- This might be normal but when I tap on the display I feel that the outer cover of the display is a bit moving towards the display, as if there is a 1mm space between the display and the outer cover, this is most noticeable when pressing at the middle of the display
Thanks

I have noticed both of those things ever since I got my HD a month ago. I think it is normal. I even read a tip in the wiki list of tips that deals with the squeaky back cover. See tip Nr. 37 there.

On my device I do not notice anything like you mentioned.

I find:
1. The back cover is loose and makes that "cracking" noise
2. There is zero movement of the screen in relation to the unit. Try taking the back cover off and using the screen.

Really? I notice it on mine but only when I use the stylus and tap right in the center of the screen. It is not much at all, but if feel as though the clear plastic on the screen sinks half a millimeter and eventually touches bottom.
I don't see how taking the back cover off would affect using the screen at all.

Thanks for your replies, my back cover is really fine, I remember trying one in the shop that had the back cover problem but the unit I ordered is not suffering from this. The noise I hear is really coming from the inside and is somewhere under the camera.
Regarding the display, this is not a problem I know but when tapping on the display I just don't feel it is solid but that plastic cover moves downwards. Exactly as Chris is describing above

Doesn't the screen have to go down? Its a resistive touch, so there has to be SOME movement right?

i would recommend going back to the store and ask the sales person to check it
this does not sound alright and mine does not make the sound you described
check "settings" -> "sounds & notification" and disable "screen tabs"" this is a kinda cracking sound too when you touch the screen, and the speaker is on the backside

Pink hue on screen...

Am I the only one who sees a pink color on the screen if the screen is tilted at an angle? I checked a floor model at Best Buy and didn't see any coloring.
If you take the device, rotate it so the corner with the clock is facing you and then corner with the Google voice search button is facing away from you and then tilt the device so you're looking at the screen in a sort of flat manner (but it happens much before it's flat) the screen turns pinkish. It also occurs when you do it from another rotation, same angle.
It sort of kills the quality of the screen since IPS is known for good viewing angles. It's a B6O, the floor model that didn't have it is a B7O.

No problems here with pink screen. Really though if you have to flip to that angle to see it what's the big deal? It's not an angle you would normally have the TF at to use.

I'm not the kind of person to whine about small things. Like I said in the first post it happens much before the tablet is laid flat. If I'm holding the tablet in a normal position and begin to turn it left or right the side of the screen that I'm turning it to turns pink. This is not a abnormal position for the tablet to be in. If I'm not directly in front of the screen it turns pink even if it's a little bit to the left or right.
