[HTC EVO 3D] Jed Dignazio:
Just got one from ebay for $12 and intalled and working fine.

For those referring to the four capacitive buttons backlight on the bottom, the problem is this:

The digitizers dont come with the little clear plastic optic pieces like the OEM. These are what direct the led light from the small board on the bottom to the capacitive buttons. I had to cut the tape with these attatched and reattach them to the new one.

On another note, I believe guides like this one are incomplete and do not give enough detail to the hardest part of replacing the digitizer. Every tutorial seems to stop at using a heat gun to take off the glass. Ok, but the hardest part comes next when you need to get the LCD out to remove and reroute the digitizers cable behind the LCD.

So this may help others a little,

The LCD is adhered to the metal case and is pretty difficult to get out without thinking you will break it into a million pieces! There is adhesive all around the sides of the LCD and under the sides of the lcd.

First you will need to try to loosen up and remove some of the adhesive on the sides of the LCD with a razor blade and pull as much as you can off with tweezers on needlenose.

Then you will need to get something long and flat like a small 6 inch metal ruler to get under the lcd and scrape off the tape under the lcd on the sides to free up the LCD from the case.

Start at the bottom. There are access holes on the inside of the metal plate to give you a little push on the back of the LCD screen to push it out just enough to fit the ruler under the LCD to be able to push it under the LCD to start scraping off the adhesive under the LCD to free the LCD. After getting out the LCD you need to thoroughly remove all of the old adhesive from the lcd and case or the new glass most likely will not sit flat in the case.

For adhesives.

The sides of the glass I use this:

For the bottom or larger area adhesion I use these and cut them to size.:

http://www.ebay.com/itm/10PC-Front-...170?pt=LH_DefaultDomain_0&hash=item4168416802

Hope this helps somebody who may think it is as easy as getting the glass off, its not..

I would check over your install as it sounds like you have some connection issues. Once everything is installed correctly your issues should be resolved.
[HTC EVO 3D] _ Brian _:
So did anyone find the cause to the 3d problem or a possible solution?

Also, has anyone had quality issues or 3d issues with replacement lcd screens?

The ugly details:

Water incident.

Took phone apart. Back cover, battery, sd card, middle housing, chip board, top and bottom chip boards.

Put what I now know to be front housing, lcd, and touchscreen glass into rice.

Put it back together, touchscreen worked fine, lcd still had perfect contrast and crisp pictures other than what appeared to be shadows (5.jpg). I didn't check to see if the 3d parallax view was working. Someone mentioned the shadows might be water marks. After removing the touchscreen and lcd and using isopropyl to clean the lcd screen and inside of the touch glass, and the marks still remaining there, I noticed that the 3d camera was not displaying properly (7.jpg) with the grid plus signs not overlapping instead being mostly vertically offset and sligthly horizontally offset. Now first I thought maybe in disassembly I messed up the alignment of the cameras, but I doubt this because the cameras are connected to eachother by a relatively robust metal housing which I am fairly sure I didn't warp. Also, pictures taken before the incident display incorrectly as well. This doesn't preclude misalignment but it points to being just the lcd.

My guess is that water damage caused the parallax barrier to be jumbled but the lcd pixels work fine and the shadows are the remains of the parallax barrier blocking some light. If anyone knows more about the details of how the evo 3d parallax barrier is put together (what its made in) with the lcd could you share that info. I am a bit concerned that the offset is not just in one direction, b/c i would assume that the picture without barrier would look similar to a 3d image on my tv without glasses, but that is only a horizontal offset, no vertical component.
[HTC EVO 3D] ronilzizou:
Hey man, i understand your problem unfortunately i am not sure what to do about it as i got a replacement for my phone when this happened.

However i did talk to a HTC technician when it did happen and he suggested that the problem was with the parralex barrier being miss-aligned during reassembly. Now apparently they have some special machines to allign them and so on which i thought was a lie since the LCD probably comes ready made to them and they have to put it together with the digitizer i doubt there's an actual alignment process during assembly.

Obviously the problem is the LCD and parralex barrier. How this can be fixed im not sure. Sorry

Black screen evo 3d

:(My screen went black after charging my EVO 3d. I tried battery pull hard rest and I even replaced the lcd. Are there any other solution to this black screen of death. Thanks.
[HTC EVO 3D] Kidsnack:
It is my opinion that your ribon cable to the lcd screen is likely loose or damaged. Mine luckily was only loose.
[HTC EVO 3D] reek2k:
I replaced the entire LCD checked the cables several times. Dont know what else it could be.:confused:
[HTC EVO 3D] raytupang:
thanks for the tuts bro
[HTC EVO 3D] Kidmet:
I got mine all taken apart, put back together. Great responsiveness, but my 3d camera is not working. any ideas?

Just saw I was missing a ribbon connector.... First test, the camera app didn't work at all... Hmmm... restarting now.

Opened it back up, made sure everything was in tight, cleaned off the flex cable. And now all is well!
[HTC EVO 3D] repairsuniverse:
Great! Glad to hear you resolved the issue and got everything working.
[HTC EVO 3D] japoco_poz14:
it's a very very difficult for me. but it's nice tutorial:)
[HTC EVO 3D] Straightsix74:
Thanks for the tutorial and for the video tut on Youtube!

I replaced my the digitizer on my GF's Evo 3D a couple of days ago, and the soft keys aren't fully illuminating. Any thoughts on what causes that?
[HTC EVO 3D] Jed Dignazio:
I had the same problem. The replacement digitizer does not come with the plastic led optic pieces that are glued on the glass under the digitizer. Those are what guide the light from the leds on the bottom board to the capacitive buttons. If you still have the old digitizer you will see the pieces glued on. I managed to peel them off and put them on the new one, just make sure you note the orientation.
[HTC EVO 3D] repairsuniverse:
Make sure you transfer over the optics from your original touch screen. This should fix your issue.
[HTC EVO 3D] Straightsix74:
Thanks for the help! Looks like I'll have to dig through the trash now, lol.

[HTC EVO 3D] fop198x:
Hi guys,

My HTC Rider (X515E/HTC EVO 4G+/Korean EVO)'s screen is broken today. Unlucky, it's difficult to find the replacement around here.

I see the dimensions of EVO 3D with my Rider are same (126 x 65 x 12.1 mm (4.96 x 2.56 x 0.48 in)).

I wonder the touch screen glass digitizer can be replaced by EVO 3D's one? Please confirm it...

Thanks for any advise.
[HTC EVO 3D] sandman121383:
cool writeup!!!!!
[HTC EVO 3D] Illmatic Enzo:
After replacing my digitizer the phone won't boot up. It will just vibrate every 10 seconds. The computer doesn't recognize it when it is connected. When the charger is connected the led is solid red for about 5 seconds then it disappears. Any ideas?
[HTC EVO 3D] Shponglized:
Does the adhesive go between the LCD and the glass screen? or the LCD and the phone housing?

I have my phone open and ready to go, But the video I was watching doesn't use adhesive.
[HTC EVO 3D] smokinjoe14:
my evo 3d thinks im touching the screen when im not, only at the top end. its sort of like the screen is slightly warped. this is my 1st "smart phone", so is this common? i would appreciate any help or advice.
[HTC EVO 3D] repairsuniverse:
It's not that common but certainly can happen. It sounds like your touch screen digitizer is damaged. Replacing this part should fix your issue.
[HTC EVO 3D] Shponglized:
So, I've replaced my screen and I had a problem to where a quarter inch horizontal strip about an inch from the bottom in completely inactive, I check all the cables and ensured they we're seated properly.

It bothered me so much I ordered another screen and this one also has the problem but with this one it's not 100% of the time only about 92% haha.

i've been trying to analyze it and it seems the only cable that could present this kind of problem would be the digitizer right??

All the others seem to go to some completely different hardware like the microphone or LED and sensor at the top.

Again this is the second screen in a row with this and i'm certain the digitizer is seated properly.
[HTC EVO 3D] Shponglized:
How do I never get a reply in this thread?? Anywho...

Is there any way that the two cables coming from the LCD screen or the LCD it's self have anything to do with my touch issue where I have a dead strip of screen but everything else works flawlessly.

Because I have now Ordered two brand new screens so theres no way it's the screens.

I also had an old damaged evo 3d that had Never Been Opened Before I took the motherboard out of and put it in my phone and it booted up perfectly

Aside from it still having the touch issue (The main problem with that was it was still the old phones brain of course)

So this rules out the Male and female ends of the connection for the touchscreen digitizer

(Note: the damaged part of the old evo was the LCD)

So I took the housing from the old evo considering the cables connected to that (Everything but the LCD's 2 strips and the Digitzers 1)

we're in perfect condition

(I was beyond careful while taking both phones apart and with every part of the procedure)

And put my (newer) motherboard in it along with my (Only) LCD screen and my (Newer) Inside back plate so that all the numbers matched up and a brand new screen. No dice

To simplify the above procedure, I've used multiple screens, motherboards, and housings. The only thing that hasn't been replaced with a new or like new piece is the LCD screen.

SO

Now that I've been extremely thurough I can get a reply [= :fingers-crossed:
[HTC EVO 3D] ramjet73:
I've never had to replace my screen/digitizer so I'm not exactly sure how all the pieces work together, but my understanding is that the sensors bonded to the glass feed position info to a digitizer chip on the motherboard, and it sounds like you've already tried at least two versions of all those components.

I found this thread where someone with a similar problem was able to reduce it using the HTC calibration app that is linked from one of the posts. That's really all I can suggest, but hopefully a representative of repairsuniverse that started this thread will respond soon.

ramjet73
[HTC EVO 3D] Shponglized:
I was so excited thinking it was gonna fix my problem, It made sense, But it didn't. But, It made sense. lol because I've used multiple everythings. So the need to calibrate was like YES!!!! but... no... ]=....

I'm sad again... I saw somewhere someone said format your sd. Or take it out, It's a no-go. So perhaps Repair universe could chime in??

All I need is someone who knows a little more about the inside of this phone than me, And I know it pretty damn well now!

This problem can be narrowed down. Is it possible my digitizer strip is in one pin too high or low?? It always seems to slide in right where it needs to be. And I have it all the way in, And the yellow tape strips have been put back on.

My last straw on my own with this situation will be buying a LCD digitzer combo. We shall see how this goes.
[HTC EVO 3D] ramjet73:
Have you contacted the sources you bought the parts from yet? They may have seen this problem before and know how to fix it.

[HTC EVO 3D] FunkALunk:
Thanks for this tutorial. It was extremely helpful in replacing my wife's digitizer and LCD screen. Advise to anyone about to try this- take your time, and go slowly.
[HTC EVO 3D] Shponglized:
Yeah, He doesn't have much to say, He pretty much asked "Did you break it?" and told me he'd exchange it, But not only do I no longer think it's the screen, but It's too much hassle for me to have to cover shipping it back, if I still thought it was the screen i'd be furious with him lol.

My only question to RepairUniverse is, Have you seen this problem?? And is there ANYWAY this has to do with my LCD screen, Because I was under the impression that the LCD handled only the display, Which seems to work fine. But that's the only thing I haven't replaced.
[HTC EVO 3D] Shponglized:
Are GSM screens compatible with the sprint phone? Because the first screen that I purchased was GSM and I have a tangent that maybe it damaged the pins in the motherboard? Unless someone can confirm that the GSM screens are indeed compatible.

[HTC EVO 3D] Tourney3p0:
Thanks for the guide. I had to use it to fix the girlfriend's phone, and it worked great. Make sure not to go too quickly on the adhesive insulation part. Get all of it out of there or the screen won' sit flush.

[HTC EVO 3D] triniverse:
skeptic

It's a nice guide...

BUT

The author of the guide is a technichan that sells the stuff required. It doesn't have to be wrong or bad, but i have my doubts.

First of all: Is it even a hardware problem? Then what is the cause? If it's a lousy digitizer, it still have to be something that caused it not to work. I can't see that noone has an answer to that.

Second, what I have read from what others wrote, the touch screen work sometimes and sometimes not. Usually you can press the power button a few times and will work normal again for a while. If you restart the phone or even reset it, it works fine for a while and after a while the problem comes back.

To me it sounds more like a software problem and not a hardware problem. If it was a hardware problem, it should never work, or am I wrong?

So my question is: For how long did your phones work after you replaced the digitizer? Did the problem come back quite soon, or not?
[HTC EVO 3D] Shponglized:
If you look back on the 13th page I've purchased 2 digitizer screens and used 2 different motherboards and 2 different housings and my phone's screen is stil 1/10th screwed up, I've begged for a reply, Even messages the author of the thread on facebook and asked for support in this section (I mentioned Evo 3d cdma general forums of course) and have had absolutely no luck. I've changed everything but my LCD screen. to fix a problem that clearly lies with the digitizer screen, But the pro's have no support for me :(
[HTC EVO 3D] coal686:
I would have helped you bro, but I've never done this before. When my digitizer was messed up, I took it to Sprint and they replaced the entire front housing (screen, digitizer, etc) for free. You're issues are why I recommend people just take it in for repairs.
[HTC EVO 3D] Shponglized:
This is my second Refurbished Evo, and I'm genuinely sick of all the representatives they have in the store.

I'm already balls deep in the replacement process, I can tear down my evo faster than a redneck can an assault rifle. If it's not the lcd, Then this phone is cosmically cursed..

I plan on getting a LCD with the digitizer glass screen already there. So i'm using a brand new screen and i'll barely have to touch the lcd at all. That, Should, Fix, It.

Just a recommendation to you guys: Get the OtterBox Defender case. I just installed it and it mounts so nicely that you think your EVO 3D is a NEXUS and it looks and feels so great you'll never stop babbling on the phone. Pure protection, awesome style. Rocks! :)

[HTC EVO 3D] RunoTheDog:
Hi,

yesterday, I replaced the digitizer of my phone. It works perfectly aside from the bottom part of the screen (where the ring is).Could this be a connector issue, a faulty digitizer issue (I doubt it since it works perfectly on other areas and its brand new - bought it on repairuniverse), or something else? I havent glued the screen to the phone yet, because I want to make sure, everything works perfectly. :)

I noticed the screen is divided into sections (see the attached picture). The section which is at the bottom of the screen (above the four buttons) is the sections which isn't working.

Thank you for your replies. :)
[HTC EVO 3D] Shponglized:
If you read the last three pages I have the same problem but my area is 1 up from yours (Second from the bottom of the 4 highlighted spots.)

Hopefully we can come together and fix this.
[HTC EVO 3D] RunoTheDog:
I'm thinking this has to be an issue with the flex cable pins. You wrote your occasionally works at that section. Mine is completely unresponsive. Did you also contact repair universe by mail?

P.S: I started a theme on this problem on Repair universe forums. Search it under 'HTC' -> 'Evo 3D digitizer issue'.
[HTC EVO 3D] Shponglized:
Yeah, I've been in this situation for weeks, maybe a month now. It's insane.

For you I suggest downloading the 2.89 RUU, If you need a link I'll find it for you. And run that, It'll completely reset your software and see if that'll help you, And if that doesn't work, Then we'll figure this out.
[HTC EVO 3D] RunoTheDog:
Another three possible explanations are: the isolation (aluminium foils and other tapes), as suggested in this thread OR a damaged digitizer (peeled digitizer from the glass covering the sensors and circuits found at the borders). As I've read in this thread, that could also present a problem.

...OR (I think this is the most probable) we may have the wrong digitizer version as described in this thread. I'll go check the s/n.

How many digitizers have you already tried?
[HTC EVO 3D] Shponglized:
I've tried 3 digitizers

2 motherboards

and 2 housings.

So it's either the LCD screen or we have bad digitizers. my original digitizer was a 1123 I'm not sure about the one I have in now.

We need to get either this front assembly http://www.ebay.com/itm/brand-new-H...059?pt=LH_DefaultDomain_0&hash=item2579fa55d3

Or this LCd Digitizer Combo http://www.ebay.com/itm/For-Sprint-...507?pt=LH_DefaultDomain_0&hash=item2ec5336593 to totally rule out this problem

It's about $55

But that's my last straw with this phone.

The aluminium foil and tape thing wont work for us, I've searched our phone for something that seemed like what the sensation has, but htc had to have fixed this on the 3d

And none of the **** is pulled back or damaged in my digitizers, and I've tried a few lol

So either we're buying borked digitizers and need to find a higher quality one or we need the whole assembly.

For me random reboots we're caused by my battery not being snug enough.

If you smoke cigs rip a tiny piece of cardboard out of your pack, Like a 1/4 of an inch.

Or find something similar otherwise.

And stick it at the bottom of the battery (not under it)

to where it pushes the battery firmly against it's connectors.

It fixed my evo.

I've since switched to the Galaxy Nexus.
