NEED HELP! - General Questions and Answers

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

G1 dev phone screen does not respond amost 70% of time

i purchased g1 from ebay, right from day1 the screen does not respond properly in fact most of the times. i need to reset soft one to at least g1 working. i upgraded to jesusfrake adp1.1 but issue is same. looks like a s/w bug or problem as if it were a h/w problem it would not have worked at all. if iam lucky it works like a charm but stops responding once i get some sms/email alert or install any app from market. can someone help here!!
Have you already tried reflashing the firmware? If not, do that. Otherwise, why don't you contact the person you bought the phone from. It sounds like it may be a hardware problem which might be why that person was selling it.
i did flash everything from bootloader to firmware to rooting. but problem remains same...it works for 5 minutes and again screen stops responding but trackball is active....right now iam on latest JF formware..
is anyone facing a simillar problem??? any work arounds....
Sometimes my home screen goes completely blank on me and seems nonresponsive for about 30 seconds. Can be pretty annoying. It seems to happen when I'm switching from an app to the home screen.
Contact HTC directly and ask for an exchange or something. All G1's have been out for less than a year and so they should be covered by warranty.
I put a new screen protector on my G1. I noticed that it had a bad reaction with the touch and I took it off. After I took it off, my touch screen got much worse. It was very jumpy and unuseable. There was a practically invisible film on the screen (couldn't even really feel it. I took a little bit of soap on a lint free cloth and wiped the screen down and let it sit for just a minute (to soak any residue) and wiped away. My screen worked perfect after that.
I was ready to call in for a replacement.
could it be a bug as if it were a hardware problem it would prevent touch screen responding at all!!!
i downgraded to rc 30 and rooted the phone, now its working like a charm!! strange though.......

Screen is blank but touch screen works ***HELP***

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

Screen backlight wont turn on

Hey,
I accidently dropped my phone in water a couple of days ago. The backlight doesnt work. Under a really bright light i can see the lock screen and it still functions. Is it possible to replace just the backlight? or what should i do? I dont believe this would be covered from motorola and I live in canada got the phone shipped from the states.
Any advice would be appreciated.
Thanks,
James
I'm guessing you might need a new screen/display. Perhaps do a search and find a repair place you can ship it and get an estimate? I know HTC offers such repairs dirctly (ship the phone, they call you with an estimate). I'd bet Moto does as well if you're not comfortable with 3rd party repair.

I have the same problem right now except mine was not dropped in water. In a bright light I can see the lockscreen and also could see the emergency dialer tonight but the keyboard was not reacting on certain buttons either. One screen said to unlock enter your gmail account info,I tried to enter my name and the period symbol(.) was not working for me. I'm thinking maybe the LCD screen needs replaced or the ribbon cable,IDK. Any help is GREATLY appreciated.
Edit: Essentially I finally got logged into the phone and the keys were working fine,the screen was still dim so I turned the brightness all the way up and turned off automatic backlight. I replaced the LCD screen and digitizer and now the phone is not starting for me. I'm about to replace the Flex Ribbon Cable inside the phone and see if this corrects the problem. Right now i cant get the phone to start up so I'm thinking the ribbon cable is disconnected somewhere because it hooks to the motherboard and the LCD or the motherboard is fried. IDK,I'll let everybody know what happens with this project.

What happen to letting everyone know? Were you ever able to get it going? Was it the flex cable? How did you get the LCD working.
Replaced the flex ribbon cable and it still didnt help anything. Guess its just the phone. I trashed the phone a while ago anyways and am currently running a rooted Droid 4

[Q] replaced digitizer, unresponsive after screen has been locked

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.

HELP!

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:
