[Q] Broken Screen

I recently replaced just the broken glass screen on my evo. When I turned it on now, the screen is all black now. I hear it still working, I hear SMS and phone calls, but cant see anything. I didnt replace the entire LCD just the clear part. When I was prying the clear screen off, it was sticking to the lcd, which also was cracked. So I got the screen off but the other part came with it. I dont know if it was connected to the LCD and it was broken off or if its ok seperated. Its just the dark looks like tinted glass that goes directly over the LCD and under the clear screen (digitizer). So, can anyone tell me if maybe I damaged the LCD screen.
Thanks in advance.

So before replacing the glass/digitizer, the lcd still worked fine? Based on your description it sounds like the lcd. You may just have a loose ribbon connection...have you tried redoing the ribbons?

I'm about to dive into the same mission. Thinking twice about it now.....

Yes the glass was broken for about 1 month but it still worked fine the LCD was working. I've tried reconnecting the ribbons various times also tried connecting the old glass digitizer, but still the same result. I'm not sure if that tinted screen was part of the LCD and is now broken or if I somehow damaged something else when I was connecting it.

to tell the truth changing just the glass is definitely the cheapest route, but from what I've read is more difficult than buying the whole replacement LCD. I paid $25 on eBay but the whole LCD is closer to like $75.

So you mean it is easier to purchase a digitizer and LCD that still connected as one piece (http://www.globaldirectparts.com/Sprint-HTC-Evo-4G-LCD-p/htc736815.htm) as opposed to doing the digitizer or LCD individually? If I went that route I would just pay a 3rd party cell phone repair shop to do the work for 100 bucks...then you can hold someone else accountable.
I found the LCD here for cheap: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=250782149841&ssPageName=STRK:MEWNX:IT
Supposed to arrive tomorrow so I will find out if the lcd is indeed the problem

thanks for that link, I may have to try that.

Water damage

Ok, so the phone turns on, LCD screen even flickers on once in a while, it won't stay on though. And everything looks just how I left it. So I'm assuming the mother board is good, the LCD is bad/fried and the digitizer glass is ok. Would that be a safe assumption?
Now, I had two other Incredibles, one with a cracked LCD, one with a cracked digitizer. Swapped out the digitizer and as long as we put the right mother board in that went with the LCD, it worked great. So I'm assuming I can't just go buy an incredible off ebay with a cracked digitizer and swap out LCD screens? And will a "New" LCD replacement screen work? Thanks!

I don't see why another LCD screen wouldn't work, but it's really hard to say with this kind of thing without just trying it, which is what people want to avoid because throwing parts at it costs money. Its not necessarily true that the motherboard on the device is ok. Its certainly possible that it could be fried, but in a way that allows power to still get to the LCD but not control it properly. Another option would be, since you will be taking it apart anyway, inspect the motherboard or other circuitry if you can see it and look for burn marks on the board that would indicate a short circuit. You can't always see them, but it would tell you if it were bad if you can see it.

Hi mate!
I have one brand new that I bought but never installed.
For your information I can advise you that you cannot change that single piece due to construction of the Galaxy S2.
I can explain you why telling my story. My Galaxy S2 went to bath and home button stopped working, so I realized I needed to replace the capacitive and home button flex module as it got damaged. I bought one original piece from a German seller on ebay and tried to replace it with the damaged one. I can assure you I'm very expert repairing phones and I know well our beloved Galaxy S2, but due to the very thin construction of the phone, the glass is glued hard to the LCD and the home button ribbon cable is between these two pieces, as you have to detach the glass from the LCD to reach it.
Why you cannot change it? You cannot detach the glass from the LCD without breaking the screen as it is truly very thin, imagine about 1mm thickness or less. As the glass is glued very hard to the screen, you cannot distribute the forces when detaching it and you'll end breaking the screen with 90% probability. I broke mine when trying and I did the whole process very carefully, knowing it was very fragile.
So, if your home button or your capacitive keys stopped working I would not recommend you trying to change it as you'll have 90% chance of having the LCD broken too.
Sadly, you'll have to change the whole front module (glass, LCD, front bezel frame and of course home button cable, all included). It's a very expensive repair, but the front module is very easy to replace and you can do it on your own.
I bought one genuine like new without scratches from a salvage Galaxy S2 from Samsung repair centre for about 80,00USD. I can give you the link if you want to buy one too.
Sad to tell you this.
Hope it can help you.
Cheers.

[Q] Separate LCD & Digitizer

I have had a bad luck and my phone fell out of my pocket and got cracks on the screen, i think its digitizer because the picture is all perfect inside the screen otherwise the liquid would have defiantly came out of the LCD!!!
I have tried pressing on the cracked class and see if liquid comes out or it forms a black spot or anything but nothing happened!!!
The combo of LCD & Digitizer costs 2500-4000 Indian Rupees while only 800Rs for Digitizer so i am thinking of only buying figitizer from ebay but i dont know any way to separate the LCD & Digitizer
Anyone have any idea on doing that and how can i put the digitizer back on LCD?
Thanks!
P.S. The touch is working perfectly even when cracked heavily!

No Display i9305

Well..After posting a thread a few days back about the display problem i was facing with my phone..It's now completely dead everything works fine except no display,It plays sound at startup even vibrate is responsive had bought this phone in USA currently in India,i've visited countless samsung service center they give me the same BS reason as parts not avalible so i wanted to ask you guys there's a way i could possibly fit i9300 LCD into i9305? and what does digitizer do? my Touch is responsive so would i need to buy both LCD and Digitizer or just teh LCD,i need it ASAP as i have my data in phone and it's locked so i can''t copy my data either,please need urgent help.

This forum is for the i747 and i747m version of the s3. You have the international version and there is a separate forum here: http://forum.xda-developers.com/galaxy-s3
The digitizer is the glass on top of the LCD that senses touch. The LCD is what you can see on the phone's screen.
I recommend replacing the digitizer and screen together as the digitizer is bonded to the LCD.
It may not be so simple because it may not be the LCD that is defective. It could be the the phone's motherboard too.

Yeah,i figured that out,thanks btw i got a new s4 got it for cheaper price as its older model

Yeah, the cost of replacing the LCD and digitizer with a really OEM Samsung is expensive which is why I look for used phones with working screens.
