i've just replaced the digitizer on my galaxy apollo, and it works fine at first, but any time the screen has been locked, the touch screen won't wake up again. after rebooting, it works fine again, until the screen is locked again. i've taken it apart again and checked the digitizer is properly connected. i don't think it's anything to do with a loose or faulty connection, as it still happens if i lay the phone flat and keep it completely still.
i'm fairly sure the digitizer is a proper one, it's samsung branded and looks identical to the one i removed. is there anything i can change so that the touchscreen wakes up properly when i unlock the screen?
i'm fairly sure that i've just bought a poor quality digitizer. it still did the same thing even after formatting and reflashing the rom. then when i reinstalled the old digitizer, it worked fine again. i carefully cleaned the contacts on the new digitizer and tried installing it again, and the same thing happened, once the screen had been locked the touch screen was completely unresponsive until rebooting.

I recently got a touch pro of a friend with a damaged screen that didn't turn on but the touch screen was responsive. Apparently he sat on it and the screen broke.
I then acquired it and replaced the LCD screen and i turned it on but all it shows is a blank black screen with the backlight on. I was tapping while it booted up and it was making that beep noise so i know the touch screen works. What do i do now.

if the lcd is damaged and you only replaced the digitizer then that wont solve the problem, the digitizer just sits ontop of the lcd and recognizes your touches, hence why it mite know that your touching the screen but the screen is still blank

I replaced the LCD along with the digitalizer. Tats what i meant.
Sounds like either the new screen is inop on fit (fraid you need another to test, then send the first back as faulty), or the fault is not the LCD itself.
Possibily its the wrong screen, or its not installed correctly, or you damaged either the screen or the controller when installing.
I'm afraid you dont have many options - take it apart & rebuild to ensure correct parts & fitment, spend £££ on alternative parts to see whats broken (or serious £££ on test equipment!), send it off for repair or give up!
I'd go for option 1 first
If your friend sat on it hard enough to break the screen, i'd be looking for any damage / cracking to the boards / ribon cable mounts and be looking very carefully at the mountings of any IC chips. Incedently, when (s)he sat on it, did the screen work at all? and was it 100% working before they did?
Okay thanks for the replies. I just bought a flex cable where the slider thing is because the old one looked a bit old and flexed out and on inspection of the old screen i found a tiny rip on the screen's flex cable too. I wait for my cable and see if it works and if it doesn't then i'll sent the screen back as faulty and get a new one and if that doesn't work then I'll give up and sell it again
hi
sorry to wake up an old thread.
so what's your solution/conclusion?
is it the flex, or the LCD that broke?
i have the same problem right now.
thanks

I have a HTC Evo 4G and recently it dropped and the screen cracked. So, I changed the digitizer but now when I turned it on, the top half of the screen is a bit distorted like its more white and lighter. I tried all the functions on the phone and they are all working perfectly. The touch screen works everywhere. Any clues on what is wrong? Any help would be appreciated.
It Would seem to me that you have [email protected]#ked up ur phone bu dropping it.. prob should get another one
the phone is fine because after i dropped it it worked perfectly fine with the cracked digitizer. the screen only get messed up after i changed the digitizer lol
Are all connections properly connected?
Yes all the connections are connected properly because I redid everything several times. I just noticed however that there was a weird watermark looking thing on the screen even though im sure it is not water
Okay so yesterday I came back upstairs from doing some stuff downstairs. i pulled my phone out of my pocket and bam, there's a white screen with colored lines all over my screen vertically. Almost like if you would take the screen and stretch it as much as you could. You can t see anything. So i decide to see if the touchscreen still works and well, it does! I can even receive phone calls.
The phone is rooted, and has a cracked but functional digitizer, no water damage nothing. I have tried turning it off and on, and well in order to take the battery out i would need to open it, which i only want to do if i need to replace the LCD.
So my question is, Is it the LCD that needs to be replaced, or could it be the hardware. Any fixes guys?

At&t Htc one mini
(The screen has previous cracks, but this problem occurred way after those were made)
I think that the LCD Panel is damaged, it is not the hardware since your touch screen is working and colours can be visible on the screen. So just change the LCD Panel:thumbup:
Hi,
I've bought a new screen + digitizer and replaced it with my broken screen. At first it didn't work...but after updating my N5 device with a OTA cable and a mouse i worked for about a day. But this morning it was unresponsive again.
I've opened it up and checked that every ribbon cable is correctly installed.
The screen turns on fine, but the touch screen is unresponsive.
Any one who has a fix for this or know what to do?
Sounds like a hardware problem to me.
Your previous screen is completely dead ? If the previous screen worked try to put it back and see if it's ok. Maybe you damaged the flex cable or something. The nexus's connectors are really bad...
I've a very similar situation here. Where did you get the screen? Mine seems to work fro a couple minutes then it's unresponsive.
I think the screen is defective. I have replaced the screens on 6 or 7 nexus 5 phones with 3rd party frame/LCD/glass units from Aliexpress and they all continue to work after several months of use.
i have this question also. i can use my touch screen at the first time but not after reboot . Display works very fine to my new screen with digitizer.
Hi,
I have a clients phone, They dropped it into water. Phone LCD worked fine, touch screen did not function correctly, and the bottom soft buttons were activating. making the phone unusable.
I orded a new screen, and decided to test it, before installing it. After removing the mid frame, I plugged in the LCD to find a strange grey snow pattern. I disconnected the battery, reseated and checked the LCD cable. I got the same pattern,
I was positive the new LCD is faulty, but not 100% sure now.
I reconnected the old screen and have a similar but not identical pattern. I can understand breaking the old LCD while taking it apart, or getting a faulty new LCD, just unlikely for both to happen.
Are there any other connections I should check. What do you guys think?
