Hello, I have a problem with the screen does not display anything slightly visible backlight. Previously, there was a problem with the microphone after pressing the microphone socket strip and insert the paper to better adhere plug in the nest everything was ok. Then there were problems with the screen more I set the socket and for a time helped. Later not come into Ocran crazy when pressed against a more powerful phone in his hand. In the end, no longer display at all. After connecting to the SlimPort tv image is displayed. Question what could go wrong? Motherboard, strip snaps onto the USB microphone or display? Regards
Was the phone ever dropped? Even a small drop can cause the screen to fail.
yes, the phone fell a few times the last day before the crash screen. So lcd touch to exchange ?
Sounds like the LCD needs to be replaced.

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
Forgive if this has been mentioned, it is difficult to sift old threads from my phone.
Mine has had the issue of front 5 buttons not working. The strange issue is that they do work when I reboot, until the phone sleeps. Then they do nothing. it makes me wonder how it can be hardware related. Tried restoring to stock and it comes back
The symptom seems software but my inner helpdesk says a full restore points to hardware. Thoughts? Replacing that flex cable would be a pain (I did open her up to check for loose cables)
any thoughts at all?
This has now turned into when i slide the screen open, the screen shuts off. Please any help?

That sounds like a failing slide flex cable. They typically run under $20 on eBay. If you decide to do the work yourself, just be careful and take it slow when separating the housing from the LCD. HTC used a ton of double sided tape to attach the LCD. I'd recommend reviewing the ifixsmartphone repair guide. The have some great shots of the interior of the phone.
Also watch a couple of YouTube videos showing the dis-assembly process. This video from Repairs Universe shows the process pretty well. Note the cables at 6:52 in the video.
On the top, the left cable is a part of the slide flex cable and it contains your front facing camera, light and proximity sensor and speaker.
The center cable is for the digitizer. Twist or flex this too much and you can ruin your digitizer.
The right cable is the LCD cable.
On the bottom you have the other end of your slide flex cable with the front buttons and trackpad.
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,
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?
So, I was trying to replace my Nexus 5s camera and I disassembled the main motherboard. Replaced my camera and everything but after I reassembled the phone, I found out that there's no display. The LEDs work fine, because I see them light up and I see that the screen is black but it's a bright black and the screen is on. So after tampering with it, I found that the little USB charger port wire board wire thst connects just above the battery (idk how to describe it, its the orange strip that locks the battery in place) had a direct correlation with the display. If I unplugged it, the screen would go dark and off. If I replugged it, it would be on again. After doing this a few times, I actually got my phone's display to show for a little while before it went away to black again. So will buying a new orange strip part work or would I have to go to the bottom where the little screen digitizer is? I'm sorry if the problem is unclear because I really don't know how to say it or explain any better. Please help.
Replacing that strip is actually not easy.
With the device open, try to apply a little bit of force on the plug of the orange strip, there are mentions of the contacts stop working after upluging/pluging back.
You probably could buy a front frame (glass, touch, lcd and chassis) from ali cheap.
