[Q] Display problem - local greenish pixels - Desire HD Q&A, Help & Troubleshooting

Hi,
please have a look at the attached image, cause its hard to explain.
It was kind of strange... it started with some cloudy pixels in the middle of the screen, they went down to where they are now and got more intense.
Its now there since about 4 weeks without change.
Anyone experienced it? I guess I need to replace the screen, or is there any other chance? In case I have to replace it, what would I need to get? The touch screen digitzer or the full lcd display?
Thanks
Susi

Although i'm not an expert on this, But i should suggest you to replace Digitizer only because it seems like Display is okay just chemical imbalance between digitizer and display panel.
If you've proper tool to disable the device and with some flat hard plastic or something try to take this to the edge where it easily go out. To me Display seems okie. Because such things happen when we put phone in tight jeans and due to over compression such happens but it has nothing to with display panel, its just chemical in between display and digitizer.
I had an iPod 4th Gen,. Same kinda Dark black spot i've noticed after single drop on top right corner and later it disappear automatically. So just saying try that first rather buying whole new panel or digitizer. Flat blunt plastic to take that bubble to the side

DASH Screen Problem GRAY BAR AT TOP PLEASE HELP ME!!!!

So, I pulled my Dash out of my pocket today, and found that the top 1/3 of the LCD is grey!!! It's only the top third, the rest of the screen is fine. It's almost like the screen is foggy on top, where you can see the icons but its grey. Please please please help me what should i do???
NOTE: I reflashed it with TMOBILE's ROMS and HTC's, and no change. PLEASE GIVE ME ANY ADVICE YOU HAVE AS TO THE CAUSE OF THE PROBLEM AND SOLUTIONS!!!! THANKS!!!
I work with LCD's and it sounds like the LCD has cracked, it will only take a hairline crack but if the crack has gone thru one of the tracks etched into the glass you will need a new LCD. You can get a new one on Ebay and I am sure you will be able to find some instruction on how to fit a new LCD if you Google it.
Fair enough. Isn't it possible that the ribbon connector is just loose? It's like a perfect 1/3rd of the screen, which makes me wonder if it's really something like a crack. Is that still possible? For example, when i reflashed it, the top bar of the bootloader (red) was perfectly the only part that was grey...
Dude, the screen is messed up. What do you want us to do about it ? There's any magical software fixes or advice we can give you. Either take the phone apart and see what's wrong (if you're technically inclined).. or get another phone!
So it's for sure the LCD?

That certainly looks like a faulty LCD to me
yup. i just sent mine back a few months ago for the same problem.

My screen is broken but what part of it?

I've searched and I can't find anyone else that has the same screen issue as me (they may have but without a picture I can't be certain).
Anyway, I was pulling stuff out of my gym locker yesterday and something knocked my Evo out. Of course it fell flat on the bench, thus causing the screen to become damaged. However, my "cracked" screen doesn't look like any of the other cracked screens I've seen online. My front piece of glass (the part your finger actually touches) remains intact and in great condition (I know I can still unlock the screen because I can feel the haptic feedback of the capacitive buttons), but it's like the screen behind it is what's actually damaged.
Is that correct? And what part would I need to order to replace it. Thanks
I believe that its the lcd
yep thats the lcd itself
Yep, sounds like your digitizer is ok, but your lcd is borked.
Thanks everyone. Will probably be picking up an EVO 3D, then selling my OG after I fix it.

[Q] Touchscreen crack?

Hi, I am in dire need of help...
I dropped my phone, broke the screen and swapped it out for a brand new one. During the swap I managed to make a very small crack at the edge of the new screen... Now the top 3/4 inch doesn't respond.
I find this very strange since when my screen was completely shattered touch worked normally, but now a small crack and it doesn't work? Does that sound normal? Could there maybe be any other underlying problems?
Any help or input would be appreciated...
Thanks
You clearly don't like your DHD and DHD don't like you
Joke.
Well, this surely sounds like interesting but as far as i know, you managed to break the connectors of touchscreen during the replacement. Touchscreen fails (although not completely) = you clearly need a new one, if it is even possible to replace. And about the thing, that this didn't happen when u dropped the phone is because it might only damaged it a little and it still worked, but when changing the glass, the damage extended.
The touchscreen is a layered device. When you shattered it you only broke the outside layer. Sounds like you broke another layer plus the outside layer this time.
Thanks for the replies guys.
Layered digitizer, didn't know that. That makes sense to me because the crack in my new screen isn't superficial (meaning I can't "touch" the crack, it's on the inside I guess).
Thanks again, I guess I'm buying a new digitizer and hope that works, sucks not being able to touch the top portion of the screen!

Digitizer replacement

Hi, has anyone replaced their digitizer on their desire z/g2? How did it go? It looks easy on the youtube vid.. have any problems? What way did you use to melt the glue? What digitizer did you use, where from?
Any info much appriciated as will be replaceing mine v soon due to 'invisible finger problem' that's driving me nuts..
Thanks..

Never done it on a g2 but should be pretty straight forward especially with a video lol. Use a heat gun to melt the glue, pretty much the only tool you SHOULD use to do something like that.
I replaced the digitizer on my third G2 after getting a refurb replacement from T-Mobile that had a black spot inside the actual digitizer glass, not on the outside or inside.
The process is very easy with the video, however, trying to keep dust and fingerprints from getting on the inside of the phone while you're trying to get it back together is a serious pain in the rear! If it's the same video that I watched, just use a hair drier blowing hot air to heat the adhesive on the inside of the digitizer and then pop the digitizer off very very slowly, because you don't want to accidentally bend the metal bezel around the screen.
You also may want to leave the original leftover adhesive on the inside, because when I cleaned mine off, light now always leaks out around the bottom edge of the digitizer, below the menu, home, and search buttons, even though I used the double sided adhesive strips covering the entire length of the bottom, so light shouldn't technically be leaking out. No biggie, though... it works like brand new, now!
Thanks for the reply.. I have seen that video and that's what I was using as a guide.. I ordered the digi today, should be here tomorrow.. the only thing I was wondering was the glueing process, as I have not ordered the double sided glue/tape stuff, as I was just hopeing to still use the original glue as I think you are saying.. I hope that works! Have to be careful like u say with dust/fingerprints etc..

Hmm, after reading your post again, maybee I should of bought the double sided tape afterall? Do you think the old leftover glue is enough for the new digi?
Many thanks..
Sent from my HTC Vision usingall XDA App
Run over to radio shack they must have some kind of glue you can use lol. google cell phone screen glue see what info you can find.
Ok, just incase anyone is interested, got my new digitizer, followed the video, used a heat gun cerfully to melt the glue, pulled the old digitizer out, and used the original glue whilst still warm to hold the new digi in, as all of glue stayed on the case rather than on the digi, which was pretty lucky.. put it all back together and everything perfect, touchscreen back to how it should be.. cost me 17 pounds.

How was this accompilshed?
I replaced the touch screen as well and the problem persists. Plus I never ran into a part that required a heat gun did I use the wrong item?
A VERY confusing part is getting the midframe to hold to the hinge mounts. The side (black dots all down it) should overlap the stabilizer bar on the hinge. I fidgeted with it for hours until realizing it goes over, and inadvertently damaged the highly sensitive LCD screen, which resulted in me taking the whole thing apart again to replace the LCD and digitizer. UGH!
DO NOT get the cheapo digitizer on Amazon, look for one with gray spots where the menu, home, back and search keys are on the back side. The digitizers without them will not work when you swap over the white button caps on the back. I feel like this information is vital to anyone who is replacing their G2 digitizer, but most guides and videos make no mention of it.
I used a lamp to heat up the glass to remove it the first time. Took too long the second time so I used a hair dryer.

So which digitizer did you end up buying and which guide or video did you follow? I am about to tear mine apart and could use the info.

Hi, I did buy mine from amazon.co.uk, there were a few for sale,, the one I bought was supposed to be a genuine t-mobile g2 replacement (refurb I think, pressumably this just means that it was from a second hand g2 that had problems and the digi was taken out - and I'm pretty certain this is the case as mine has a thin film (which u leave on) over the back of the digi covering the tracks etc, which had a few very small air/dust bubbles under it (just noticeable when screen off), where I own a desire z, so now it sais t-mobile instead of htc, but I can live with that.
The small grey bits that you talk about were floating about or stuck on my digi when I pulled it off the main chassis. I had a look, and as far as I could work out, were possibly just for giving colour to the tiny led's that give you light to the home/search keys etc (I may be wrong on their use), but if you look closely, the tiny grey things have even smaller rectangles on them that relate to the positions of the led's on the circuit board. So I picked the remaining ones off the old digi, put them back in their correct holes and stuck the new digi in. I've had no problems (with a digi from amazon with no little grey things on it) so far, but maybee this is due to mine being a second hand original part..
Edit : Now after reading your post again, you're talking about bits that are actually on the digi itself, not the white caps that I'm talking about! Whoops. I didn't notice any grey spots on the digi itself, but I guess I must have them..

i just replaced mine with this one:
http://www.ebay.de/itm/230685692541?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649
actually it says HTC on it and looks a lil bit differently than on the picture.
never the less, i replaced it really carefully and checked every connecting.
But somehow the Touchscreen doesn't work at all.
Can anyone help me ? what could be the problem ?
Wrong digitzer ?
is it okay, that the digitizer has direct contact to the frame where it is glued to ?

Hi!
I have the same problem, I have asked it already here
So you had invisible finger press in the screen, and the screen was bad responsive?
...Just to make sure my problem is digitizer problem! The service wont change it in warranty unless the problem is there all the time! But its driving me crazy! why is it happening randomly, why isnt it all the time? How could i make the screen to do this problem when i'm at the service?

[Q] Screen artifacts

Hope t his is the right place to post this. Just replaced the glass on my TM217A and now have "blobs" on the display. What did I do wrong? Any way to fix it? They are on the LCD panel itself, noticed them when I turned the tablet on after remove the old glass and before installing the new.

it looks like you bent/deformed the part,
you mean the digitizer right ?
as to fixing it, you may have to get another replacement.
those bubbles are probably sealed in now. you could try remove the part gently
and clearing away the adhesive to let the air [which is what it looks like] escape,
and try again.
