I just replaced a screen in a Trinity (Dopod D810). The touchscreen initially wasn't calibrated correctly so I ran the alignment tool in the settings, and after a few attempts, I calibrated it properly and the touchscreen was working perfectly. Now the touchscreen is not working properly. The top half of the screen responds to touch, but no matter where I press in that region, the screen thinks I'm pressing the top-right corner. When I run the alignment again, it responds to all the touchpoints but it never successfully calibrates and it keeps bringing me back to the alignment screen.
The current settings in the registry entry for touch calibration are as follows:
484,558 244,286 263,815 750,820 707,295
I've found a few other threads here (the most helpful being http://forum.xda-developers.com/showthread.php?t=355010) and I've tried the settings from that thread. The screen seems more responsive, but still not correct because the bottom half hardly responds and the top half seems to respond when it feels like it.
Can someone please post their D810 touchscreen settings so I can try it? I've tried the settings from my Touch Cruise, but the screen is still doing weird things.
This is a customer's phone so I need to have this fixed ASAP.
I'm thinking that it may be a faulty digitizer, but that won't explain why it worked perfectly when I first calibrated it.
UPDATE: NOT FIXED yet, but now the backlight is dead. I just turned it off, and then turned it on again, but I can only see the screen content if I shine a torch onto the screen. The LCD hasn't leaked. The backlight just died and the connectors in the phone are fine. Perhaps this was a dodgy screen.
Any ideas?!
since the device has a recessed screen, take the cover off to get at it.
take a soft cloth or something and clean off all the garbage on the digitizer and back of the plastic. make sure everything around the lcd is free of dirt.
usually, if there is something pushing down on the digitizer while you calibrate it, it will totally bork the alignment over the course of 10 minutes to an hour.
my kaiser is currently having this issue, though i put it though alot more hell then i should have... so i suspect its suffering from other issues.

Hi, Just got my MDA Vario III, and it appears the screen alignment that WM runs on first boot will not work. By that I mean its asks me to align the screen, but it will not register the taps with the stylus or fingers.
However, it does know when I touch the screen as it brings it out of powersave. I downloaded this Remote Screen Alignment program, which is able to skip the screen align process, but then when I have done that the taps from the screen are all over the place - because the screen hasn't been aligned. The keyboad works fine for navigation around the menu's.
Does this sound like a DOA device? Or am I missing something stupid?

It might be a simple loose connection or something trapped between screen and bezel. But I would not be even thinking about that, it would be going straight back under warranty. Thankfully, this is not a common problem with the Kaiser and I think you have just been unlucky.
I assume you have not put on any screen protector that might be causing this behaviour> Otherwise it is a DOA and nothing you can/should do other than return.

Thanks. I hope its not common! No screen protector, but I did try one first before first boot. I immediately removed it when the taps weren't working. I'll send it back tomorrow, thanks.
Dont tap. Just lightly drag the end of the stylus around each target until it proceeds to the next one.
It's common and should be fine.
Thanks unwired. Whilst that does get a response from the TyTn II, and moves the align crosshair, unfortunately it just loops the alignment process indefinitely. Arranged an exchange with T-Mobile without a problem

If the future device does it, just try what I suggested but be as accurate as you can.
Unwired's method works for me as well. My Kaiser always seems to lose the ability to detect stylus presses (but finger pressure works) every time I use it on a plane which I assume is due to the cabin pressure. When the screen is reset, everything goes back to normal. Has anyone else noticed this, or do I have some defect that is only going to get worse?
I got the second Kaiser, and it happened again. But I immediatley used unwireds method, this time being extremely precise and only moving the stylus slightly. It works fine now, and stylus accurancy seems to be ok.
I still think it's strange, as I have had an HTC XDA before and a tap was sufficient on the screen align process. Furthermore it clearly states "tap screen" not "tap and drag".
My last three Wm devices (Prophet, Hermes and Tytn 2) have all been reticent to respond to alignment taps... but carefully moving the stylus around the target has always fixed it.

For me it is more like 'tap-and-hold'. I make a firm tap on the '+' symbol, then keep the stylus pressed on the screen for one second, then release. The '+' then moves to the next alignment point.
Just for the record, I think the problem is common!
I've seen many people who have unresponsive touchscreens, and now I'm one of those unlucky people. And nothing works. And I don't have warranty because I'm in a different country than the purchase country and the reseller here only services phone bought in the Middle East. #[email protected]$#@$#@
Hello all.
So, long story as short as possible:
My Tilt got run over, LCD screen was busted but I could still make and receive calls by sliding it open, hitting the call button and using the keyboard to dial and 'enter' to connect.
I was also still able to connect to the phone via bluetooth from my mac, as well as syncing it on my PC partition.
Eventually, I think I hit too many random buttons and turned the phone off or something as I could no longer get it to dial out this way. I was always getting the flashing green and blue lights though.
After some research (and un-won auctions on eBay) I decided to see if popping in a new LCD screen would fix my situation.
I installed the new LCD last night, and the machine is almost back to living, however, I now have the current problems:
When the phone boots into 'normal' mode, the screen is display is very truncated. It doesn't display the full HTC updated today screen and won't respond to touch. It says 'no service' but wi-fi seems to connect. If I slide it open, the keyboard lights up but doesn't respond, neither do the front keys. Also, I get only a solid orange light in the upper left LED.
If I boot the phone into 'Safe Mode' it responds to touch, connects to the AT&T network, connects to Wi-Fi, etc. The front keys still do not do anything, and when I slide it open the keyboard does not light up or respond. Also, I get both the green light in the upper right and blue in the upper left.
Another thing, when I slide the phone open and closed there's a slight ripple in the middle of the phone like something is 'pressing' on it from the back.
Sorry for the novel. Any help is appreciated. I'm considering 'clearing storage' and returning it to factory settings or flashing the ROM. I've taken it apart and put it together like four times now, checking, double checking and triple checking connections.
Thanks!
Sounds like one of the headers isnt fully seated in the display region. IIRC there are two that I had to deal with with my 10min LCD swap routine
Yeah, I think you're basically describing symptoms of having put the phone back together wrong except that it's interesting it responds in this 'Safe Mode' and interesting that it would happen after four retries
It's probably going to need a hard reset then! You might want to check nothing has been bent, warped mountings/plastic could be the cause of the screen ripple issue.
Were there any active components on the touch film for the display? (Assuming you have replaced that too with the LCD, or that they're one whole unit) if that is the case, they may be different, newer revisions? Really grasping at straws there though; at the end of the day, the poor phone has been mauled by a wheel... best of luck!!
Thanks for the thoughts! I guess I could try and break it down again. As far as I could tell, everything looked like the phone in the disassembly directions; nothing appeared unduly bent or mangled.
"Sounds like one of the headers isnt fully seated in the display region."
I'll google it, but what 'headers' are we talking about? The small metal bits that seem to touch the upper outside edge of the LCD screen?
Would an improperly seated header cause the other symptoms? Unresponsive other buttons (keyboard, front keys) and connectivity issues with the network?
"Were there any active components on the touch film for the display?"
I got a new LCD and digitizer (is that what you mean by other active components?).
Thanks again!!

Any cable that attaches to the circuit boards, re-seat every one you can find. One faulty connection can cause a lot of problems. I have a similar problem with a button on my PSP but im to lazy to fix it.
Hi everyone!
Sad thing happend with me, 4 days ago i fell into a river and sadly ma diamond was in the pocket. I dryed it for three days, turned it on, everthing else works, besides the screen light. So i dissambeled the phone to bits and pieces, only i didn't took the LCD out(read it from somewhere that you can't put it back on afterwards so it will work). I reassambeled it and still same situation. If you look it from a angel you can see the icons and even touchscreen works. Only problem is still the backlight. So is there something i can do to make the backlight work again or i have to buy a new screen and is it hard to swap the screen ?
Hi,
Not sure if you will need to replace the screen, if you can get to the power settings you can see if the backlight has been manually turned down. If this fails and a screen replacement is required i will tell you how easy/difficult it is once i have replaced mine, due to unfortunate circumstances.
yeah, i got into the power settings, everthing is okey there like it should be , so i have to change the screen. Is there some kind on intrcutions for changing it? it would help me a lot
Hi,
Last week I used to be outside with much rainy condition.
Though it never got totally under water, many times it's screen got wet with substantial rain drops.
Slowly, phone started misbehaving with following symptoms,
1. Around 10% of left side of touch screen doesn't show response. I enabled show touches from developer option and when I try to touch left side, say "a" letter in keyboard, it doesn't show touches and pointer jumps immediately to left edge.
2. Many times, I am not able to unlock phone as no touch are detected.
3. After unlock, many times though I am not touching phone, it shows couple of pointers (I enabled show touches in developer option to trace this) on left edge. It keeps moving resulting in erratic behavior, say screen zooms in and out, some icons clicked automatic, deleted automatic etc.
4. Sometimes I noticed that capacitive buttons are also not responding.
For all above, I have to off (not complete switch off)and on the phone. After few attempts, it becomes responding except point 1 above.
I have reflashed ROM (Vivikat) just to ensure it's not software issue.
Now it seems hardware issue with following two possibilities...
1. It's matter of some moisture in phone only. I have to try hard to dry out all moisture and phone will become responding.
2. Digitizer has some issue and may call for replacement (I don't want to do that...:crying.
Can you guys share your views/experience and advise?

I just had touch screen issues but not with water or rain. It was the CPU. Almost whenever I overclocked it, I had touch screen issues. Both misbehaving and not behaving at all. Change the CPU frequency and restart the phone and see what happens. :good:

Thanks for your reply.
I have never overclocked my device.
However, I tried to underclocked it if by any chance, it can solve the issue.
But issue still there.
A small portion of left column on touch screen seems not responding or giving erratic behavior.
Does, water can damage digitizer to that extent that can not be recovered even after drying
Or, I should keep hope and wait more before I go for digitizer replacement

If the digitizer is damaged, it is probably done. But if you can open the open, check the digitizer and see if there are any things stuck on it. My recommendation: ask an engineer to open it and clean it with the special spray they use to clean electronic parts. Maybe the water has had only a side effect and it will be fixed by cleaning the digitizer.

I loved to hear your words, as I have still hope for resolving issue without replacement of digitizer :fingers-crossed:
I'll find some engineer to get it serviced....and post update.

You're Welcome buddy! :highfive:
Hello everyone,
I have got one problem... I broke digitizer of my HTC Desire 500. So I order new one and to be sure, also LCD screen. I replaced, and...
After turning on, everything works fine. Digitizer works properly, screen shows normal picture. But after few minutes - restarts (I don't remember well) backlight of my screen goes down and now it have no backlight at all. I rebooted phone many times, I remounted screen and digitizer to be sure that connections are fine - but no results. I restored factory settings of phone with no effect too. :/
Please help, what happend? What could be the source of problem? I don't want to order new sceen if it could beak too ;/ I read other threats about coil problem in other HTC, but I cannot find any coil in my Desire's motherboard (maybe it is hidden under plate that covers CPU and other parts). I performed tests of light sensor and it works fine. Buttons lights fine too. The problem refers only to LCD screen, and backlight doesn't respond during test.
Anyone help?
same situation
Hello kowal_luki,
I'm just in the same bad situation.
After a bad fall of the phone the screen broke so I ordered a new one for replacing it.
Opening the phone I noticed that also the LCD (and not only the external screen) was broke so had to order also the LCD.
As precaution tried to power-on my device without a complete assembly and everything seemed to be fine, so I decided to glue the LCD to the outer screen (the touch screen) with a LOCA TP-2500 glue.
Then I re-assembled it up: at first the image was a little bit disturbed but the back-light was working; after few second the back-light turned off. I checked the cable, after that the image went perfect but the back-light still dead.
Did you find a solution for this -still not explanable- problem?
