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.

Hi all,
I am at my wits end on this problem if anyone can offer any adivice it would be greatly appreciated. So let me give a recap of what has occured thus far. The water damage tag for some reason turn pink thus i am unable to get warranty exchange. I am pretty certain that the phone has never been expose to any water of anything of that sort, but i do live in houston, tx so might be humidity or what not that cause the tag to turn. Anyways.
1. This all started after i flashed RRE 5.2 RC3. Initially after a successful flash everything seem normal and fine. Then next morning i woke up to a frozen screen with many verticial lines running up and down the screen was almost unreadable. Initially i thought it was a bad flash or just random lock up. I did a hard reset and tried to enter the bootloader. Black screen, it does seem like the backlight is coming up but nothing on the screen. I can hear the phone power on and boot successfully into windows. Activesync connects i can browse the contents of the phone.
2. After flashing to stock att rom and stock htc roms same symptoms. So at this point i am thinking crap bad LCD screen. so I ordered both the digitizer and lcd screen for good measure. I replaced them hoping that a bad LCD was all. replaced both screens and i powered on the phone. same problem. black screen. The phone still powers on and boots into windows. Activesync still connects and i cna still reflash the phone.
3. I work extensively and do both desktop pc and notebook repair. I am not new to dealing with small electronic repairs. but at this juncture i am unable to identify the cause of hte malfunction. i am hoping maybe some of the gurus here might be able to shine some light on the subject.
Thanks in advance for any help.
I would have followed the same approach; your description makes it sound like it might be some kind of backlighting issue at first read. I'm inclined to think it might be a cold connection (bad connector) on the main board.
Silly question, what happens if you power up the phone with the keyboard exposed?
*EDIT* Not sure if you have been here yet: http://www.mikechannon.net/
Cheers,
i just tried to power up the phone with keyboard exposed. Powers up the same as with the keyboard hidden. Still boots up fine but black screen. I already have the service manuel dowloaded. i have checked around with several repair places both local and on the web. Seems like no one has any parts for the att fuze/touch pro gsm except for the lcd and digitizer and a speaker.
its quite possible that it is a main board but as the same time it might be something as simple as a ribbon cable. i have contacted htc about doing a possible repair and they want wayyyy too much for just a main board repair almost $400 USD.
Anyone have a bricked/ non working touch pro they would like to sell ? =P

Could be a bad ribbon cable ... and firmly pressing around the front/back of the unit shows no change?
pressing the phone front and back show no changes to display. in a very dark room I can see that there is light emitting from the display but its just the screen is not displaying anything visable. this occured both before and after i changed out the screens. I'll do another visual inspection of all the boards to see if there is any bad resistors burnt out circuits etc.. but i didn't notice anything mentionable during my first 2 inspections. Maybe 3rd time is the charm.
Thanks for all the feedback thus far Hilaireg it is quite appreciated. All this venting has at least made me feel 1000% better than after i replaced my lcd and still same problem at least i don't feel like a complete idiot!
Sorry I couldn't be of much help ... you've done all the steps a seasoned hardware person would do.
Do post back to let other folks know if you get it back up and running.
Cheers,
you have a pm fkoong.
I have possibly the same problem. Phone got wet, dried it out for 2 days (in a container of rice). Phone worked but had "water marks" on screen that disappeared after two days and everything was fine for about 2 weeks. Then one day (happened to be humid misting rain eve in Charleston) the screen is blank (hint of backlight only). A soft reset and it seems OK for about 1hr, then blank again. The hard resest screen displayed OK (readbale text etc), but didnt work. But as I write this, I retry to document it results correctly and the NATF ROM is reloading and the screen works! We will see how long!!
Well.. not that long, the end of the ROM load and it went blank again, seems like a video driver problem. The Press VoluP to boot does show some red artifact.
Trying hard reset again (No SIM no uSD)
The NATF v4.4 loads and gives me the Tap screen, Align Screen, stylus, loads customization, opera, tf3d, then loads a bunch of files under ...... and then the screen goes blank again, seem like what happened last time, so Ill try loading a fresh ROM copy... later
Anyone else who owns a Touch Cruise have their touch screen just stop functioning altogether? I came back to use my phone which was just sitting in the car and the touch screen no longer works...Obviously this did not happen due to being dropped, though it was a little warm nothing unusual by any standard.
All the hardware keys work, everything else...just the touch screen is dead. Has anyone else had this happen and if so were there any steps to reviving the screen or was replacing it an option, if so what did you do?

I had this problem with mine, it was just to send it to their lovely repair center through the dealership since I still got my Warranty, they exchanged the front panel, witch senses the touching. Depending on where in the world you live you should be able to by a separate one, or get it repaired by them. I hope it solves for you...
Thanks, I am well out of the 1 year warrant and in the US, which is not even where this phone was originally warranted so there is no chance of that.
I believe the cost of repair outside of warranty, and the time it would take that I would be out of my phone would not be worth it. I am hoping that I could purchase a replacement screen and repair it myself...Anyone have any direction here to do so?
Let me clarify something in regards to the malfunction. The screen itself is still visible and I can see everything as I would normally on a fully functioning lcd screen...The screen simply does not respond to any touch!
Touch Screen stop
hi i install the wwe-hero-3g and it stop it say"Tap the screento setup the windows" my phone is a at&t 8525 so what can i do.
i have the exact same problem. makes the phone useless
Hi try getting into the screen set up, ie where you tap the screen on first boot. You can use the program "mymobiler" to operate the screen through the computer.
Hope this helps!!
Same ****..
Have the same silly situation. Can´t even install the above program as it is impossible to respond "yes" to question about installing.
Have just ordered a replacement digitizer from this source:

Don´t know if I will be able to fix it and I have also ordered a new Iphone as
I´m getting tired of all the problems with my loved Touch Cruise.
hi - I have a htc desire s thats on original firmware. I recently replaced the lcd/digitizer as a complete unit with a genuine replacement part. The phone was working perfectly in every way up until a few days agoo when i noticed that the side volume buttons wernt working, so i replaced the volume buttons as well with a genuine htc part. Now the phone starts up pefectly but the digitizer is not responding to my touches anywhere. Ive checked that ribbons are seated properly several time but still no response from the digitizer. Ive been told that the digitizer needs recalibration, been told to make a "goldcard"...which i did...also use the file "PG76DIAG.nbh" onto the sd card,,,reboot phone...get into the bootloader menu and it should give me the option to recalibrate the digitizer...but i get no such option in there...any help and ideas please..thanks
Hi
My son recently gave me his old Moto G5 phone. The phones charging board was broken and the screen was very badly cracked all over (it had a screen protector) and was generally not in the best of condition.
My son had bought a replacement screen several months ago, but had not got around to trying it. The battery was also totally flat.
So he gave me the phone and I installed a new charging board and the new screen and charged the battery.
Unfortunately an area of the new screen does not respond to key input . This area is a line of keys towards the bottom of the screen (not the bottom though).
My son says that he had not noticed any such problem when he last used it (he kept using it until the battery went flat; he then purchased a new phone).
I've tried doing a factory reset. I've removed and re-connected the display cable onto the main board and these have not fixed the problem .
I am not sure what to try next :crying::crying:. I could purchase yet another screen in case this new screen has a fault (probably unlikely?).
Presumably it could be the main board (digitizer?)...How can I find that out?
Maybe I have done something wrong on the install, but seems odd that the rest of the screen (as far as I can tell) works ok. What might I have done to have caused this problem?
Has anybody got any useful tips as to what I could try. Seems a waist of a good phone, not to try and repair it.
Thanks for reading this.
A couple of days ago my Oneplus 5T wich i have had for about 3.5 years stopped responding to touch input. The display was still working.
I ordered a new screen online and replaced it with the old one. But still, nothing changed and I was unable to use the touchscreen.
After some research online and here on XDA I found out that it might be a bug with the software, and I should be able to use my phone again after resetting (unbricking) it.
I also brought the phone to a local repair shop, and they told me, I did not unplug the battery during repair, and therefore something shorted and I broke the new display.
I did unplug the battery, but its still absolutely possible the connector connected itself back in on accident (while i tried to press the new display in).
Is a short like this actually possible? Is it more likely that the new screen was already broken?
