Hi,
some time ago my digitizer stopped working - there was visible a small dark spot, which resulted in erroneous signals to my Raphael. I replaced the LCD and digitizer with a new one, but still there is something wrong - Raphael does not respond to touch - tapping the screen doesn't cause effects. But if the screen dims, touching it restores the normal brightness. And what is strange that Raphael sometimes restore brightness immediately after getting dim, and this cycle repeats over and over again.
I uploaded new ROM, then the stock, always the same. I have no idea what might be damaged, any idea? A relay, tape, cable...?
Thanks for any help.
Ok, I know everythink. It's broken flex tape connecting LCD and mainboard.

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
was mainboard
I dropped my TF700 with the dock and it fell on its back(tablet). It closed shut and when i tried to restart it i do not see any display
later the display comes up but in jagged lines half black and half display, the touch doesn't seem to respond , i can see that it boots
and i can access it on my computer all the files and entire system but i cannot do anything with touchscreen and lcd. after repeated touching
it has the touch sound that comes not very often.
I opened the screen and i see no physical damage to the screen. Is there an inverter board of LCD that might have gone bad due to that
or has any one faced this problem , so that even if i have to order a replacment part i know which one to order first i thought of
ordering the LCD + Touchpanel but it looks like i am doubting that the LCD has gone bad.
Can anyone please help if they have faced this issue ??
Hi,
History:
I've got Sony Xperia tipo. While it was in my pocket yest, I got a call and unfortunately in the hurry of picking the call i dropped the phone down. The phone's screen was the point of contact with the ground and after that my there were lines on my screen. The screen glass is intact, there are several horizontal lines making the visiblity poor. However, after the hit, touch has become a bit unresponsive. it hangs for 17 seconds exactly and then resumes to work fine.. this lag occurs quite frequently....
Problem:
> horizontal Lines have appeared on the screen, thus making the visibility poor
> Becomes unresponsive for 17 seconds, after that throws an error notification "the "------ " became unresponsive.
Question:
> Is it the digitizer or LCD screen or is it something else at fault ?
Please Help me in resolving this issue
Thanks in advance
Have a nice day
If touch doesn't work and the screen is weird, then you'll probably need to replace both.
With how the screen looks, you need to replace the LCD screen, the digitizer MAY be okay still. If you open the phone up and check to see if there is a loose wire. If there is, reconnect it and then put the phone back together. If there is no lag after that then the digitizer will be fine, if there is lag then you will need to replace the digitizer as there is a fault in the wiring.
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 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?
