My desire Z is reasonably new a few months old. But Itd been let without use for about a month and when I took it out I noticed now when I open the keyboard the screen goes purpleish, not all over but tinged in places. White is purple in some places and there's green blotches near on screen icons. It looks like the colours have been dragged to the right slightly. I think its a hardware issue but its a pain
When keyboard is closed the problem usually isn't present or sometimes the distortion is minimal. ALSO iv now noticed the hard QWERTY keyboard no longer seems to function right eithar. Some letters arnt working most of the time.
Anyway ink how to repair it or know a guide? I this it mit be something to do with the cable.
If you want to strip your phone down to check that the ribbon you see when sliding the keyboard out then look at this

There is videos showing you how to take the phone apart to replace the hinge spring,sounds to me to be a faulty display though.
If you do take the phone apart there is a screw with void sticker so your warranty will be good and gone,if it is a faulty display you could still un root and get it replaced?
Wait to see if anyone else has any ideas before breaking out the screwdrivers,
No its not a faulty display. Display is ok when screen is closed. Also I used a tweezers to push the cable in as much as I could at the back and it fixed the screen. . . . .QWERTY was still not as good as it shud be (but slightly improved) but after maybe 15open and shuts it came out again.
So this means I have to open it and unloosen it right? No simpler easier way to do it?
And the keyboard problems are caused by the cable too afaik.
The method in the video is the only way I know to gain access to the ribbons socket,still think warranty is your best bet as you have pointed out the keyboard is faulty,if you open it up and cant replace the void sticker/something goes wrong,then the warranty is gone and you have a broken phone...........................
Oh I forgot to mention I have no warranty so its no loss to me xD. The keyboard was fine when I got it though so it didn't come from factory faulty.
Ok then,if you want to have a fiddle about inside then you will need a 5 Torx driver to open up the back and a philips(very small)helps to have a magnetised one as the screws can be fiddly once you pop the case open,watch that video in the link I gave you to see how its done,best of luck
Lovely I'll give it a go. Thank you
Good stuff,If you need any advice PM and will see if I can help bud.

My Hermes 8525 display has gone fully white.. I cant see or do anything on it.. Anyone got any idea why this is so ??

Did the display fade to white? Or did you turn your screen back on and find it was all white?
There's a known problem for HTC Hermes with the D-pas causing white screen, and a little mod to fix it by putting something behind the D-Pad itself such as a small very thin piece of foam. Obviously this requires taking your mobile apart.
If you flashed and then got a white screen I'd try getting into your bootloader and take it from there....

Hi,
had the same problem. I took the battery out (read this in one post somewhere here) and then everything went ok. I also saw the post about the dpad, but was not nessesary. Although I think I was just lucky. I think that it happens often, you should do that.
Regards,
They display faded into White.. It was working fine. one fine day, as i was replying to a text message.. or when searching phone book.. or any action.. slowly the entire screen faded into white.. once i did a restart and removed the battery a cpl of times and it seemed ok.. but now its permanently white.. i cant even enter boot logger mode.. or even if i did, i wont know or cant see that i am in bootlogger mode...
Any ideas??

1st, scuse please 1st post, bad day at work...
1. Does it get hot anywhere on the front of the hermes. A mate of mine had a capacitor burn out that caused white screen...
2. Try opening the keypad then reseting. This worked for mine BUT it is a pressure issue and as I closed it found that touching a certain spot in the bottom right corner of the casing would make it whitescreen again.
Other than that you might have to open up your hermes to try and fix...
Heres how to open up :http://michael-channon.spaces.live.com/PersonalSpace.aspx?_c02_owner=1
Make sure you have the correct tools though as it makes life easier. No. 6 torque key and a flat bladed screwdriver are good..
Cheers...
I just had the same problem on my TyTN. Everything but the cover and battery was replaced in warranty and now it is solved. It seem to be the connectors to the screen that crack.

Read the thread for this and see if you are having the same problem as many of these people. It helped me figure my own problem out a lot. Good luck

This is the same thing that happened to me At&T told me it was the D-pad because that broke before my white screen issue and they replaced it for me
white screen probs
had the same problem on a few hermes now....replaced the screen to no availl....after many other trials i replaced the circuit board under the d-pad and problem sloved.....i havnt got the know how to test the board for faults but i would agree that the board is the problem any one know what the function of the part is exactly....screen controller????
screws...
I had the same problem and was able to fix it temporarily using the foam-behind-the-Dpad-connector trick several (like 6 or 7) times but it always went white again within a few days. I finally got it to stick by loosening the tiny screws on the connector very slightly...haven't had a problem since. I'm not entirely convinced it wasn't just completely luck though. But seriously after so many times trying different thicknesses of foam and banging my head against the wall, I'm glad something worked. And now I can take it apart and put it back together in about 7 minutes, so that's a bonus! Might be worth a try if the foam thing doesn't work. Good luck.

Hey thanks all you guys.. I guess its the D-Pad connector issue.. will follow the resolution suggestions.. I will let you know if that helped...
mine fades to white everyonce in a while then comes back or i have to take the battery out and all is fine. it did it when i put wm6.1 on it. was perfect before i did that.
hi there
ive been having this issue for ages and have opened my handset to reseat the connector no fewer than 14 times in the last 2 weeks
today i had a breakthrough though,
what i did was completely cleaned the connectors using rubbing alcohol and a q-tip
the important bit: RESEAT the connector properly. it may look like its reseated but look at it side on and it should be perfectly flat, and if necessary push on it a little to make sure its seated
then, on the back cover (which you removed to get access to th d-pad) you'll notice a little rectangle 'pad' there roughly in the same place as the d-pad connector
get a white sticky label, or a post-it note or whatever and stick a little piece over that
then seal your phone back up and it should work.
i cant promise anything though, and any damage you do to your phone is entirely your responsibility
Hello, I saw that someone else asked a similiar question before but they did not word the question correctly and got little help.
On my HTC EVO logic board, there's three tan "ports" (I don't know what they are actually called). One for the front camera, one for the LCD, and one for the front panel.
While walking home one day, my screen started showing a dark spot. The spot got bigger, and I decided to take apart my phone (something I'd done before a few times) and try to clean things up. I put everything back together, and the LCD would not come on. After numerous tries, I finally decided the LCD was damaged. As I went back in the phone, I saw that regardless of whether you flipped the black tab on top of the LCD tan 'port' back or forward, the cable was capable of being pulled out, e.g., it was not secure. At the time, I thought nothing of it, but now that my new LCD should be here, I'm worried.
Is my LCD not working because the 'port' is broken? If so, what can I do to repair it? (I heard it is very difficult). I'm worried, because I paid a lot to buy a new LCD and will be unable to send it back.

Also, my front panel cable never sits 'perfectly'..that is, I have to connect everything else first, and then try my best with the front panel. The tape does not stay down flat completely.
These sorts of connectors can be fixed,but there is quite a bit of skill involved. Upload a picture and I can tell you better how hard it is. What I can tell you is that you probably cant do it yourself. I base this on the fact that those who have the necesesary skils will instantly know its going to be a pain. In fact,its easy to screw it up ,and sometimes you do,even if you DO know what your doing. Since I dont want to take my phone apart,Ill need to see a picture of it before I can tell you anything more. One thing to keep in mind is that sometimes the ribbon cable CAN be pulled out anyway,and is making good contact and there is some other problem. If you have not installed the new LCD,install it and see if it all works. If so,your good to go. As a general rule,the connectors are delicate and its not a good idea to pull them out. In fact,dont disconnect them if you dont have to. They have a limited number of connect/disconects they can take and they are very easy to break.

Well, I don't really have a means of taking a quality photo except with my computer webcam but I'll try in a second. I can't really show you because there isn't much to see. The little black bar that flips up and down to 'lock' the port is ineffective; the cable can be pulled out regardless. I know I can't fix the port/connector by myself, so I'm hoping that's not the issue. You have given me a lot of hope though. The new LCD should be here by Wednesday at the latest, so I'll be able to test it then.
Does my front panel affect the LCD? Since I dropped my phone on the corner, even with a new panel it does not sit 'perfectly'. I don't think they're related though.

I dont think so. I bet your ok. Just dont keep playing with the connector. I know,Ive done it. I sit there messing with it,wondering,is it broken? Is it good? Then the little black peice comes off in your hand or the plastic breaks and "well its sure broken now!" Remember,that little latch does not so much hold the cable in place as hold the cable against the contacts,if its making contact,its good to go.
Hi, all. The new LCD I receieved did not work. There are very minor differences in the two; such as some type of blue gunk on the silver part of the LCD, the connector is more of a dark orange on the new one while the original is a yellow-orange, etc. Also, again, the connector does not 100% fit in the slot. It goes in, but a small corner sticks out a bit and you have to either hold it in or clip it in [which I can't, because the black clip is broken].
The only possibilities I can think of are
A] Because the little black thing is damaged, no LCD will work in it. Therefore I need a new phone.
B] The LCD does not work.
C] The LCD is the wrong size.
At this point I want to just give up and get a new phone, which is very heart-wrenching because I love my EVO and I doubt I can afford the only other phone I like, the Samsung Galaxy S II Epic Touch 4G.
Is anyone able to identify what connector is used on this phone for the LCD? I broke a pin on the connector while trying to repair a cracked screen. I would like to buy it and re-solder it on to fix the phone.
Can someone link the correct connector maybe from digikey.com?
Broken latch
I too have a problem with the connector... the plastic part that connects the ribbon cable to the main board has broken. There must be a place to buy these tiny plastic latches... does anyone know? Your assistance will be greatly appreciated!

Hi,
Only thing I can think of is that somehow it has damaged the cable from the touchscreen or the tiny wires that feed into the cable without damaging the screen. I came across a brand new screen I was replacing once for someone that had a similar problem where the bottom left hand corner wouldn't respond to touch unless there was firm pressure on the screen to create contact, and this was a brand new screen. It could also be that the touchscreen connector needs to be pushed back onto the board if it's come a bit loose.
If this is the problem, you can fix it by yourself although I'd have a good look around youtube, there are heaps of DIY videos of how to replace screens. If you do go down this path I recommend you replace the touchscreen/LCD/LCD frame in one go, as it's generally already pre- assembled the only thing here is that there are 3 brands of LCD's HTC used with the phone and they aren't all compatible, and you can only tell by pulling down your phone and looking at the LCD flex cable colours, and the other thing is that the screens that are available aren't always the same quality as the original. If this sounds to hard your best bet is to take it somewhere and diagnose the problem just in case it's something else
Its been some days, I'm experiencing this weird touch screen problem.
My DZ touch screen doesn't respond properly.
For example:
If i see an image and slide just one finger up and down then it would zoom in and out. And then the whole screen becomes unresponsive.
It seems as if, its touched by itself. Even the softkeys would go numb. Only the haptic feedback of my search button works at that moment.
But the trackpad works perfectly.
But, If i lock and unlock the screen using power buttons, it would work properly for some few moment and then again the problem repeats.
At present I'm repeating this process of locking and unlocking screen to use my phone.
One even worst weird thing is that, if the device is connected to a charger and kept on the table or floor. This problem doesn't occur.
I have done system format, restored my nandroids and even changed Roms. The problem still exists.
Please note, i don't use any Casing or covers that would press the device hard for malfunctioning of screen. I have even removed and replaced my screen guard.
I'm sure, its not a software issue.
And even i dont think its a strip issue, because i dont use my physical keyboard always.
Can anyone say what hardware issue it might be..?
Or what i need to do? I'm really out of options.
Do i have to replace my whole screen or the digitizer..?
Thanks...
Thats no fun,
As you stated it's more than likely a hardware fault, the two most likely culprits would be the digitizer or the main flex cable
Which would be this and this
both relatively easy to replace depending on your experience
in 4.x and up ROMs check the developers setting to show touch or use apps like
z device test
or
yet another multitouch test
these wont help you fix the issue but may show you where the bad points are on the screen
best of luck
I know the problematic spot. Its near Search softkey. Even Yet another multi-touch test would stuck at that spot....
As you can see in the image, that i'm not holding anywhere, still it shows that somewhere around Search softkey its touched by itself.
In second image, If i move my fingers around, it would show the other touch responds, but if i slide near search, it would go and stuck there itself.
So, i guess i would first go with the flex cable.
In actuality I'm leaning toward the digitizer in your case, but its possible to be either.
And if you have a spare phone it may be worth disassembling even without buying anything. On a G1 I once fixed a similar issue just taking out the digitizer and cleaning the contacts on the ribbon and the edges of it as well, when I put it back it worked like new. I think some dust may have gotten into the edges but it may be worth a shot before buying anything... But could make matters worse so if you don't have a spare, buy parts first
Best of luck
Sent from my Nexus 7 using XDA Premium 4 mobile app
I guess i should try disassembling and clean it first. If it still persists then i would go for digitizer.
And thanks for giving a hope.
Thanks...
Hey,
Just curious if anyone has had an issues with a Vertical Black Line on there screen,
i notice it mainly with things that are orange or red,
everything else seemed to be fine had the phone a few months,
i sent it in for repair,
but just curious if this is a common thing,
I've never personally heard of that happening, and its definitely not happening on my phone. Did you grab a photo before you sent it back at all? Curious.
Sounds like a hardware issue, such as screen gone bad, or ribbon cable or other connection becoming loose.
The issue of vertical lines on the screen popped up fairly occasionally back in the days when slide or flip-open keyboards were in vogue. The moving joint between the screen and the rest of the phone would sometimes cause the ribbon cable to fray or become loose.
same issue
got it back from repair . same issue said on the slip they flashed software.
issue still there mainly when u look at red images

That's pretty f... up! This is most definitely hardware issue and they should have taken care of it. Problem is always to describe the problem to repair center good enough to make them see it.... Next time you should leave a pic on the phone with which the prob is easily recognizable and make them look at it.
Yes ,
A red background will be on it when its sent back, and nothing elese but the background,
i explained it pretty good to them , but will certainly be sending it back again
got it back ,screen replaced and bezel ,software says official now and not tampered and says relocked its workin great
