Hey people!
Ive recently put the weight of a couch on the screen of my phone. My screen was already cracked from a previous drop but everything looked fine still.
After putting that much weight on my screen, half my screen is permanently black unless I put pressure near the bottom of my phone. It somehow releases the blackness temporarily.
My question is [Q] do I need to replace just the screen or did I screw up something else as well?
TIA
I have the same problem with my screen now. To fix it you need a new LCD. The cracked up front part is called the digitizer and you might as well replace them both together now. Only problem is to find out if you have a wide or slim LCD connecter cable and there's no way to tell until your phone is disassembled. Good luck!

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..

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?
Hi everybody I have a question regarding a screen problem I have.
Like I mentioned in an earlier post I accidentally spilt a lot of pure alcohol(the kind you use to disinfect a wound or something) on my HOX.
After a while the phone screen showed some strange grey shape on the lower right part of the screen and a bright white long shape looking like water jumping from a fountain on the left side starting from the bottom of the screen extending to almost the middle of the screen.After turning it off for 8-10 hours they grey shape dissapeared and the white remains and it doesnt look like it will ever go.
Strangely enough the HOX has no problem everything is working but I noticed that some apps are working somehow over the white shape covering it and some others like facebook seem to be under it making it visible.
I made some screen shots to show you the problem but stangely enough this white shape is not shown at all in the screen shots!!!!
Can anyone tell me where this thing might be?
LCD? Digitizer? elsewhere?
HTC funny enough suggested a factory reset to solve this and if that doesnt work(like there is a chance that it will...) to just send it to service.
I plan to play dumb to service hopping to fix this under my warranty as the phone has absolutely no scratch or anything anywhere as I never even dropped it once.
Do you think they can somehow find out what happened of maybe they will fix it under warranty?
Thanks a lot for your time reading this and I d love to have your opinions
Any photo?
Perhaps some alcohol got stuck between the lcd and glass...

Looks like overheating damage by a component beneath the screen, possibly something reacting to/affected by the alcohol.

When you say beneath the screen do you mean beneath the LCD as well or just beneath the glass?
I am just thinking that if its beneath the LCD it would probably not show plus the phone would have some kind of functional problem(it works just fine) wouldnt it?
Beneath the screen assembly. It looks like (possibly) some component or board has caused damage to or affected the digitizer, as your actual display seems ok.

So the service corrective action will be a screen assembly replacement or you think that something more will be needed?
Also if the digitizer was damaged wouldnt the phone use be affected?Cause the device has not been affected in anyway.
Everything works like it used to before this damage.
Send it of for repair, youll have to pay of course, how much tdo you like your phone?, that's the question.

I like my HOX very much otherwise why would I pay 428 euro to buy it?
Of course what makes the HOX stand out of the samrtphone crowd is the amazing display so of course I want it fixed.
I will try to cheat saying I know nothing about it(the phone doesnt even has a scratch) hoping waranty to cover this but if this doesnt work I ll have to pay 196 euro for screen replacement.
Although appart from that mark nothing else is affected I am worried that perhaps a screen replacement might not be enough if the digitizer is affected by something beneath it.
Do you think that a screen replacement will be enough to solve this problem?
HTC will give you the digitizer and LCD, especially if you end up paying, which will then get you a new bezel and unibody all still tapped up in protective coat, I've had it done for my phone, 160gbp.I even think you get the Onex+ version screen, gorilla glass 2.Could be wrong

My phone was working fine when the screen was cracked. I didn't check if it was working right before I replaced the screen but I'm assuming it was. While replacing the screen I put some scratches on the digitizer. I also wiped it with a paper towel and it change color on some part of it. When I turn the phone on the charging light, to left corner works. Also the bottom soft keys light up as well. But that's it the screen does not light up at all and the phone doesn't make any sound when it turns on. Could I have damaged the digitizer in any way? I don't see how replacing the screen would have done that. I also noticed that while the phone is off I can see through the glass screen and see the digitizer. Where before it would look all black.

Did you replace the display, or just the glass? If you scratched the digitizer theres a good chance thats the problem. What did you use on the towel that caused it to change color? Thats also not a good sign. If you could explain a litte better what you replaced, what you used and how you did it, it would probably help to figure out what happened. But either way it does sound like it was damaged in the process.
I Just replaced the top glass not the whole digitizer and all. I didn't have anything on the paper towel but I think some oil from my hands. Then I tried to clean it with water so it looked like a really big smudge of oil. When I watch fix it videos all the digitizer looks black and mine looks silver. Also from reading on Google lots of people had this happen to them. It seems maybe the hair dryer made the phone too hot, if extreme heat could damage it. Or just too much pressure. Since I did put some scratches on it maybe I applied too much pressure. Lot of people are saying even the slightest bit too much pressure can damage it. But I still don't get why mine looks silver and not black.

I think the heat related discoloration is mostly seen when the display is on. Not sure about when its off. Cant say why it would be silver looking though. I would think youd need more heat than a hair dryer for that to be the cause though.
It may be from the water. Its just a guess though. Ive only ever seen or used rubbing alcohol or certain types of cleaners.
Hi,
Unfortunately for me i dropped my phone and cracked my tempered glass in several places. gladly the screen underneath was perfectly fine after drop however, it has developed a fault as the screen won't turn on at all. I tried turning it off and restarting and although i can hear the boot up logo sound i see no picture at all. i can receive calls but cannot answer due to screen not displaying.
The screen had four main pressure cracks.... one is top left, one on the ear speaker, one bottom middle and one bottom left of phone. hopefully you can see it in picture.
Can you give advice on what to try or do to resolve this? will i need a new screen or disassemble to see what the issue is?
I've only had the phone for 2/3 months at most
Thanks in advance
looks like i will answer my own question....
i bought a replacement lcd & digitiser, one complete unit and swapped the necessary components over to new screen. all is working and good. not sure if the screen is repairable but there are other parts inside this screen worth selling on. it still has a non cracked immaculate screen along with the charging port and other stuff inside old screen.
at a cost of £70, i consider this an expensive fix
Thanks for the input kakawak
cheers
