Greetings dear people of this forum!
Few days ago my phone's display started behaving in a very weird way (could be a minor drop down).
When I press the power button to draw the pattern, the whole screen is full of disturbed horizontal lines (pic_1).
If I apply some pressure on the screen's bottom right corner (pic_1 - red dot) it gets back to normal and doesn't even flickering at all (pic_2).
Howerver as soon as the display goes off because of the turn off time, too close to the face when making a call or just switch it off with the power botton, the problem reaccures.
I am very sure it is hardware related, because on the screenshots there is nothing like that and it is persist in the boot sequence. In my opinion this is some kind of faulty connection, I have already take the phone apart to catch any loose connector, but nothing changed after that.
I feel like I have to buy a new screen, but I hope I can repair it somehow, because it can works very well after my acupuncture therapy.
I have bought the phone second-hand, and I know there was a screen replacement, so its not the original one.

Could also be any gaps or something that can cause the lines(display gets pressure from wrong installation).
2 options basically. Loose connector or faulty LCD.
I don't think it's software related.
If you can give it back, then you should. If not, then you can either try to fix it by yourself by replacing the LCD assembly (with the touch digitiser).

Yes, You were right, as I thought too. The reason behind the problem was the LCD.
I have replaced it and now it works like a charm.
Thanks the response!

Hi!
I got a weird problem. Seems like the buttons on the screen part have some problems.
When I press some of the button on Universal screen don't work but instead
the up button keep pressed, not phisically but logical.
It's annoyning because I must reset it to back a normal function.
I opened the screen part I checked and made some pression all over the conecctions, without the
back case worked ok, but when I put the back case on the screen the problem returns.
Please any ideas, solutions.
Thanx again, greeting from Chile
I have the same problem. If I rotate the screen around a bit the buttons work fine, but if the screen is on straight the buttons sometimes just keep on going.
I thought it's a faulty cable between the main body and the screen part, but seeing how it works for you maybe it's a connector problem? I bought a new cable and will see if it helps. Mine has a screen color issue too (screens is blueish).

I tried to identify what the problem is, but I didn't find anything. I tried pressing the conecctor to the buttons parts , I cleaned the pins, pulled the flex cable, and nothing ....sometimes it worked and sometimes not. Whatever I will to exchange or replace with another.

Sounds like a cable break too. I think with mine it went wrong when I turned the screen too far. Somehow the rotation was not blocked anymore and I think it got twisted too tight and the wires in the flex cable were damaged. Wiggling the screen would help sometimes, but the problem deteriorated over time.
I finally received the new flex cable I ordered. I paid 44 GBP (66 EUR) for the flex cable to a company in Hong Kong. I think they are raising the prices of these cables, because I thought I saw them for 30 to 40 euro earlier.
Installing this new flex cable indeed got rid of the problem with the buttons and the problem with the blue color of the screen. Both problems rendered the PDA practically useless and now it's working again.
Unfortunately I somehow managed to break the camera. It says "failed to initialize" when I start the camera software I looked it up and people claim it could be caused by dropping the PDA, but I guess completely taking it apart and putting it back together might cause the problem too
To replace the cable I needed to take the PDA completely apart:

Hi everybody,
I have a question regarding the HERMES screen/digitizer with which i have always had problems...
I have been using my O2 XDA Trion for a bit more than a year now and i have always had the screen (dis)alignment issue. As i do not have warranty anymore i decided to check out the source of the problem one week ago, so I did a lot of research (also in this great forum ) and diss/reassembled the Trion without any problems. The problem now is : While I was testing the Trion's touchscreen with the included pencil suddenly the screen behavior changed. I am, as you can see on the two pictures below, not able to get in to the lower right corner of my screen anymore:

"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
There is no way to get in the lower right corner of the screen, even touching at the very low+right point doesn't work. My questions therefore are:
- Do you think the root cause is a digitizer failure? (The LCD itself still works flawlessly...)
- Do you think buying + installing a new digitzer might fix the issue? Might it also fix the screen alignment problem?
- How "hard" is it to install it? Through my research in this forum i heard that soldering is needed?
Thank you very much for your answers in advance,
Cheers,
Philipp
Looks like a digitizer issue as you can't get any sort of selection to happen in that area but the LCD is not damaged as you said.

That's very probably true. The other thing that can cause wierd effects is anything that may be pressing on the digitizer around the edges underneath the bezel. Unfortunately some Hermes suffer from the digitizer remaining sensitive to touch even under the lip of the casing.
Regardless, I would not be tempted to replace the digitizer only. Although it's theoretically possible, it's not an easy job (LCD and digitizer are stuck together and contacts have to be made, positioning accurate , danger of cracking the LCD etc etc). Despite extra cost I would personally replace LCD/Digitizer as one unit.
One final point is that replacement carries a chance that things will not be perfect after replacement. This is because of various sensitive parts that can be affected when dismantling. eg. the d/pad connector.

Other way would be to find a "broken" Hermes (make sure its not the same problem or whitescreen) and use the whole slideout screen section. I did this and it worked fine...
Got my spare Hermes off ebay....
Cheers...
Hi guys,
just wanted to give you some information on the results.
I ordered the replacement screen 2 weeks ago here in Germany for about 45Euro (which is quite cheap i think, yeah ).
Everything worked fine so far. I installed the screen as described and it directly worked without problems. I have been using the Trion for more than one week now and the best thing is : Even the screen alignment problem seems to have dissappeared with the new screen, yeeppeh
Btw: I was a little surprised but the "new" replacement screen had the same date of manufacture on it as my "old" screen (which is in fact >2 years old). Nevertheless it worked...
So thank you all for your responses and help!
Cheers,
Philipp
I have a weird problem with my Wildfire's screen after I did an OTA upgrade to Froyo.
First, the top of the screen stopped working. The taskbar wouldn't work and I the top wasn't responding. All of a sudden, after approximately a month or so, it started working again.
It worked fine for a few weeks and then the right side of the screen has a problem. All of a sudden it started automatically hitting the spot on the screen where the letter "P" would appear on the keyboard. When I was trying to type out a message, the letter "P" would get hit on its own over and over again. When the keyboard was not open, it would still happen.
I felt it might be a virus, so I did a hard reset. This still didn't stop. So I switched off my phone and kept it in a desk for 48 hours. When I switched it on again, this problem stopped, but the right side of my phone was not responsive (approximately 4 milimeters of it).
I can see that this is clearly not a hardware problem and has something to do with the firmware/OS. I'm not too sure what to do. I've tried flashing new ROMs on to my phone, but it remains the same way.
Incidently, when I tried flashing "TheNextSense" ROM on to my phone, the phone started hitting the portion of the screen where the "P" key would appear. When I switched back to CM7, it stopped, but the right side was unresponsive.
Is this something to do with the memory? Or is this a known issue with upgrades/certain ROMs?
Any help will be appreciated. This is driving me crazy
why do you think its not a harware problem ?
for me it sounds like it is one. (temperature or short circuit problem)
IANAHRM (I Am Not An HTC Repair Man) but I think the touch screen connector has just slightly worn loose, perhaps due to temperatures. It sits on the right side of the main board (left side of the phone itself). I know the Wildfire can survive quite a motion shock so that shouldn't be it (I hope).
Nandroid backup and restore jobs heat up my phone quite a bit, did this occur on your device as well while you were installing roms? That might explain the change in behaviour.

Nope. It's never heated up till now. This happened all of a sudden, and it gets worse with upgrades. It's like, for some reason, the phone isn't able to function properly with any ROM other than the stock ROM. I'm going to try to put back eclair on it today and see whether it works. Will keep you posted.

Because it doesn't always occur. It kind of gets fixed on its own after a few days. It's like my phone has a ghost in it
I put back the stock Froyo ROM and now the problem is 50% better - much of the portion of the screen that was dead earlier is now responding. But the rest still isn't. Any ideas? :-(
My ROM is NexusHD2-ICS-4.0.3-CM9 V1.1
The last thing I did was watch a video on YouTube (Application). I then got a black screen the next time I tried to unlock it, this has happened a few times with this ROM so I normally just soft reset it by taking out the battery.
However this time I did it again and my phone turned on, but was constantly black. It vibrated as if it was turning on but did not do any boot logo. Tried booting it into the tri-color screen and nothing still.
I have realised though that it is still booting up, and working like normally, but the screen is just black, it is a lighter black as if it's responding if I press a button. I managed to unlock my phone by doing my pattern, and I can hold the home button and feel a vibration, so I know it has booted into Android.
I'm just really not sure what to do, I've looked all over the forums and found one similar problem but no solution. I think I can get into the tri-color screen if I hold down vol down but it won't show the screen, I just know it is in the screen as I see the light is constantly a light black as if it is constantly on.
Shall I try Task29 or does anyone have any idea what I should do?
Edit*
I can now run AndroidScreenCast and operate my phone from my PC. I can control my phone as if i was normally, but the screen is just black. Like I said it turns onto a light black when anything happens but hat's it. Is it just my screen afterall? (It has been cracked for over a year now but no problems upto now..)
My guess is that you accidently disconnected the output cable from phone to display.
This should be the issue since there seems to be no screen but interactive elements.

Any idea if I can do anything about that myself?

Hmm the cable is right under the hardware buttons.
You can try pressing around them to have a chance of getting it back (no guarantee and if you break your display its not my fault).
If you are experienced enough you could remove the LCD but I don't know anything about that.
Sent from my HTC HD2 using xda premium
yes, you could be the ribbon cable connector to the motherboard, you must fully remove the display and see if the latch on the cable connector is closed.
Also check if the cable is securely attached to verify you see two small ends' near the copper plug is attached to the plastic connector on the motherboard.
good luck

My HD2 appears to have some big time screen problems, so i wonder if anyone has any sugestions.
Background
It never really lived in a case and the inevitable drops happened. That ended in about November when one drop too many caused the screen to crack. I replaced the digitiser and lcd screen which got it all working again happily, though beecause of the amount of fiddly stuff involved the chassis never truly fit perfectly, the screen protruded ever so slightly above the edge of the case, etc.
Fast forward to last weekend when for no apparent reason (i hadnt dropped it or anything) it started to behave erratically, not registering screen taps and then suddenly doing many things at one, making it almost impossible to send text messages and use effectively. My thought was that maybe it was losing calibration so tried aligning the screen but nothing would really happen.
Furhtermore it seemed like the bottom section of the screen had almost no responsiveness at all.
I therefore thought it might have something to do with the connections inside the machine, so i decided to take it all apart and check all the connections were sturdy. Thats when the real problems started because when i put it back together and turned it on, i had a horrible display that makes it next to useless.

I actually just fired it up to check that it was sill the case and it seems slightly worse than this picture!
So the questions. Firstly, does anyone know what might be the problem here. Is it likely to be the connection between the processor and the lcd, or soemthing more of a problem? How easy is it likely to be to sort it? A case of a completely new screen needed? Or is it likely to be something fairly simple? And would those problems with teh LCD screen be a similar cause of the calibration problems (i thought the digitiser might not be working properly, hence the original decision to take it to pieces!)
Hope someone can help. Happily my upgrade was due last friday, buit it would be nice to have a working phone for spare use etc.
Steve
It seems to me a bad LCD(100%) and probably a bad touchscreen!
As i suspected. Has anyone else with a replacement digitiser/lcd had any similar problems?
