HI!
My phone is the HTC touch HD. My screen had a small dust particle between the touch screen and the LCD. Therefore I dismantled the phone as I have replaced touch screens of the same model phones before. In the process of removing the phone something has happened and now the LCD is not working but touch screen and the phone is functioning. (I connected the phone to the pc via MyMobiler and can see the screen on the PC through the software). I replaced the LCD with a brand new one too but still nothing shows up (not even a white screen)
Any ideas whats happning?
where can give this phone to repair in the UK?
Any place to get this repaired in the UK?

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

Greetings!
Today my phone dropped of the desk and closed...i powered it on again vibration was working but screen was black!I tried my old lcd same thing...
For what part should i search t find or it's pointless...??
probably a hardware problem,the clue that the software works that it vibtrates,ry and buy a new scren or go to a shop to fix it
I've change screen i tried my old one(touch(digitizer) problem)..so i think this ( cgi.ebay.co.uk/Keypad-PCB-Flex-Cable-HTC-TOUCH-PRO-T7272-/320597490986?pt=UK_Mobiles_Accessories_RL&hash=item4aa5197d2a ) will solve the problem...
PS: Cant post link cause of forum restrictions.
Hello Dimgr
I lost my Touch Pro last month ( MB gave up) other part are perfectly working. As HTC service center said MB is gone i got courage to look inside deeply.
Therefore i can can the link is NaviCap assembly which is noway handles screen.
What i can guess i could be BD Slide
I though it would be that cause the screen connects with navikey.My phone hit the floor with the screen and keyboard was on!(i cant explain it sorry for my bad english :/) Any other suggestions??I dont want to rip my phone .
Just one day my TP stopped responding to touch, everything else working.
After few days screen went black, but phone was starting Navi key were glowing while charging, even phone was getting detected by PC.
I gave my TP to HTC service center they said Mother Board has gone & it was costing almost a new phone.
So i decided to sale the parts.
I sold Navi key to one of member on this forum only & its working perfectly, this confirms my doubt that Navi key is not the bug in your case as well.
Three things could have happened.
1. The best scenario is the jolt from the drop just dislodged the ribbon cable connecting to the screen. Resolution: Reseat ribbon cable on screen and on body of the phone (requires to open the phone)
2. The screen simple is busted and needs to be replaced.
3. The motherboard got busted and needs to be replaced.
1. The phone is open i even tried another screen all ribbon cables are checked :/
2. The screen seems to be ok... I dont think that both screes are faulty!!!
3.R.I.P. Htc touch pro...
My situation was same & HTC service center concluded that motherboard is gone.
So i believe your motherboard is also gone & this means there something which stops working after physical.
Because after my phone stopped responding to Touch i gave some shock with a hope that it may help in case of loose connection, but next day screen gone black.
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 am trying to fix my Nexus 5. Couple months ago I dropped a mug on the phone. The result: cracked screen. I ordered a new screen with the whole front housing so only thing I had to do was remove cracked screen with frame and replace it with new one. When I did it I turn on the phone but I saw only a short blink of the screen. After lots of attempts of I came to conclusion that I probably damaged the new screen or it was already damaged. So the screen is black. When I plug the phone to PC everything works perfectly. I can browse the memory etc.
I would like to ask you whether my conclusion is correct and the only issue is the screen which has been damaged by me or the seller.
One more thing is that when I charge the phone or it is attached to the PC beside the black screen I can not also see any light from notification led.

If the old screen can still display an image, move the parts back to the old screen to check for issues.
HI. Thx for reply. I don't remember whether cracked screen was functional in terms of displaying image. I will try to attache the old screen and will let you know.

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.
