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.
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.
few weeeks back i changed the roms
which i used to do noramlly
but this time the screen started showin white screen when i was sliding and when i tap on the screen or at the borders it returns back to normal state
whether any problem with the touch screen
whether it can be managed with my self or it needs some technicians help
souds likes bad ribbon cable..
See if others feel the same..
bad ribbon wat it can be done locally or has to be sent to htc cc?
i dont have htc cc locally
from where to get the ribbon cable or my kaiser
I have recently purchased this phone via swappa and haven't had any issues prior to this and that has been three weeks (other than a light leak).
The issue that is happening is the LCD will not turn on. When the phone is unlocked via knock on or power button you can move your finger over where the lock circle would be and feel the vibrations showing that it does register the touch. Then usually I would just hold the power button till it rebooted and this would sometimes fix the problem, on a side note the boot LG logo and boot animation do not show up during this time simply the lock screen would randomly appear.
That is problem, now on to what I tried to fix it. I have put on an entirely different rom and the problem persists, I have also flashed a different kernel on the stock rom with no avail. I at first thought it could be due to a faulty proximity sensor, but the last time the screen was on I checked it with sensor box. One way I have been able to reproduce the problem is after locking it putting it in my pocket and waiting around five minutes, this then will make it so the LCD does not turn on ( Which makes it seem like it has something to do with deep sleep). Also something I just found since I was actually able to find the power off button, the screen also won't turn on when the phone is off and plugged into the charger (this makes it seem like hardware issue). It seems like as long as I keep the phone from going to deep sleep the LCD will turn back on.
Some of this makes it seem like a software issue other things make it seem like a hardware issue. I just was wondering if anyone had any ideas or if I need to buy a new screen, if the mobo is bad, or if I could fix this with software. Any and all ideas are welcome.
Thank you all in advance.
Anyone noticed something similar?
Sometimes when unlocking phone with the unlock button or by double tapping it wakes up but is unresponsive to touch, the brightness alters with random intervals, wallpaper flickers. The phone becomes usable again after a few locks and unlocks with the button , although very rarely but still sometimes it automatically locks itself after unlocking.
Factory reset didn't help and before that I was using all the latest updates.
Is this a problem on the hardware side?

Pretty sure mine is. It started with similar issues and has only gotten worse. Flexing the phone a bit makes the screen go all wonky and it's the only way I can get it to come on/become responsive. I will more than likely have to send it in to Sony. Ugh.

Idk wth all that means. Some of it I can guess at...but for a phone that was treated rather gingerly...to have behaved in such a manner after X amount of months (7, I think it was, before stuff started going wonky) w/out the screen being cracked or damaged in any way...the answer is lost on me! Hopefully it doesn't happen again.
