HTC Sensation - Digitizer Replacement - Touch screen unresponsive - Unable to S-OFF -

Hi Folks,
Here is my story.
I have replaced my broken digitizer on HTC Sensation. At that point i was not aware of multiple versions of digitizer's in e-bay & Amazon and i need to select the right one stuff...From this thread
I realized after replacing & touchscreen was unresponsive.
With inputs from From this thread, i tried to RUU, then realized that i have to S-OFF. But in the process of trying to do S-OFF,[touch screen not responding] while connecting to a PC, phone is not detected [May b that i have to select USB debugging option in phone]
So, am struck now & can anyone help me what is the way out now?

Thanks

You might have to reinstall the broken digitizer and root/s-off the phone then replace it... You need the touch screen to do some of the s-off steps...

broken digitizer
Hi. can anyone help me to fix my HTC sensation? I buy it with broken digitizer but will still work perfect, and after i change it start to do this problem. Ween i push button to unblock screen don't want to does not want to react instantly, i must move my finger on digitizer about 3-4 seconds to respond normaly. Have you ever encountered this problem? know any solution?
i try to install another room but same problem...

How do you remove the digitizer? Is the heat the front and ply it with a guitar pick the only way to do so? My digitizer ain't broken, but my lcd got wet and I want wipe the stain off.

I have the same problem. what make it worse is that I have cut the ribbon of my old screen. Could anyone help out, if there is other way to do it?
Thanks

Hi there they're is a great instructional video on you tube on how to replace the digitizer on our device, if I remember correctly there is also a video on you tube on how to open and take apart our devices. I have watched the digitizer replacement video and its extremely helpful, advising on exactly how to do the procedure . Go over to you tube and take. Look at the video . I think it will be extremely helpful! Best wishes and hope I've helped!

Have a question related to this (don't wanna start a new thread).
If I want to replace a cracked screen do I need to buy the digitizer, lcd, or both? My screen is cracked but works perfectly fine as usual.

Unresponsive HTC Sensation XE Beats Touchscreen
I'm having same problem, replaced old touchscreen :
PYD V1.1
SW-10 94V-0
E308252 1145
With (? = missing letter or number):
PYD V1.0
B?-10 94V-0
E?082521123
The touchscreen is totaly unresponsive . On top of this I didn't care about the old digitizer
and cut the flex cable, now I'm stuck with an Sensation XE Beats with an uresponsive screen,
if there is a fix arround this I will highly apreciate. :fingers-crossed:
I tried to find exact same touchscreen model than the old one, but can't seem to be found.
Is there someone with the same old digitizer who replaced with other model number that perfectlly work or partially?
There is this fix in an other tread : http://forum.xda-developers.com/showthread.php?t=1360638
But impossible to do as touchscreen doesn't respond.
Also could it be possible that the new touchscreen is defekt?
I read in the other post that new touchscreen worked at least partially, this one not at all.
Thank in advance for any answer.

[Q] omnia w, touch respond only while charging

anyone had this before:
the touch screen responds only while charging. when i remove the usb cable the screen does not respond anymore? hard and capacitive buttons works fine.
any help please?

The capacitive buttons are part of the touchscreen panel, so that doesn't seem to be the problem. Do a reboot maybe?

i even did a hard reset and still the same problem

hmm, curious
its not going to be the OS level software then, unless you flashed that ROM that's been going about.
can you perform a hardreset via the bootloader options, do the buttons work in there? if they don't then perhaps internal damage or if you flashed that ROM perhaps its been a bad flash
have you flashed that Omnia W ROM that's been going about?

Touchscreen not working even after a digitizer change

Hello,
Recently my touchscreen suddenly stopped working. Everything else is running fine it simply doesn't recognize any touches. I have had the digitizer changed with a brand new one and it still is not responding. The phone boots up fine - you can call it but the screen is non-responsive. Do you guys have any ideas to what the problem might be since I changed the digitizer and it still doesn't work.

Hi, My touchScreen sometimes is not working, but after i restart, everything works fine.
1. I think that you should do Factory Reset, If Factory Reset does not work, it seems that the digitizer has problem.
2. Becareful when you change the digitizer, you must buy the same digitizer with the origin of your fone. When you buy a different one. your fone has no driver for it that's why your new digitizer does not work.

Thank your the reply kind sir. Would it be possible to change the driver of the digitizer? I got mine off eBay and it was for a Sensation 4G but I can't tell of the exact model. I'll try a factory reset but if I can find a driver that would be great.

this thread maybe help: http://forum.xda-developers.com/showthread.php?t=1360638

It could also be related to the little metal ground that is not connecting with the metal strip on the outer casing

Messed-Up Display

Hello XDA,
My Nexus 5 running CM12 5.0.2 nightly will not respond to the touches anymore infact when I press the power button to activate the display it acts as if someone is touching it randomly messing all the apps that are running and opening and closing many other things.
Furthermore it displays weird and burned lines throughout the screen. It was not dropped, no water went inside the device or anything. If it helps I did install the OTA updates that CM gives us.
I have also attached pictures so you may get a better understanding of my problem.
Thanks in advance.

Hmm I see. Well since a month HAS passed, its definetly not the rom thats causing the problem, i don't know if anything regarding the software could even be causing the problem. Its 100% hardware and by that i mean the screen, you should change it, the touch and also the display are messed up.

Is it possible that a driver update could fix this, if so then how?

I hate to be the bringer of bad news - but your screen is toast. Fortunately you can replace the touch and display components all at once.
http://www.amazon.com/Skiliwah-Digitizer-Assembly-Google-nexus5/dp/B00HN0U168
Here is what you need to perform the repairs - and here are the procedures for disassembly.
https://www.ifixit.com/Teardown/Disassembling+Nexus+5+Display+Teardown+-+liquid+damage/32410
Trust me, it's not that difficult. Unfortunately, it's a bit pricey ($60 for the screen and digitizer), nevertheless much cheaper than a new device or sending your device in for repairs.

Problem Solved
The screen isn't toast, neither is the digitizer. I have 2 of these phones. The parts which cause problems like this are the main board and the ribbon with the USB connector on it, which also attaches the screen & digitizer to the main board. One was showing lines exactly like this, & also no touch. I put a replacement main board in. Works great now. The other, wouldn't even turn on. I put the main board from the first phone in the second one, it still wouldn't turn on. I replaced the ribbon cable, it turns on and perfectly replicates the issue from the first phone. So now, I have one fully functioning LG Nexus 5, and another which turns on with the same problem as yours. This is good, I started out with 2 of them that were useless to me. So, it appears that your display and touch issues are caused solely by a bad main board. A replacement main board costs somewhere around $75. After swapping stuff around, I have 2 bad main boards, 1 bad USB ribbon & 1 working phone of 2. Not bad, not bad at all.

Xperia Z3-Black backlight only,no image.

Hello. I got this Z3 with a broken screen, when I got it it had only black backlight, no image, but the LCD cable on the bottom was cut, so I thought that was why it had no image.
So I replaced the screen with a new one, but the issue remains, no image, only black backlight.
Tried restoring the software with Sony PC companion, updated to latest version, but it didn't help.
The phone boots fine, touch works, I can select options and sometimes I even get audio readouts of what is on the screen, just no image.
Is this a dead motherboard or something else? Because I went through a couple of new screens, none worked, so I'm out of the ideas.
I haven't encountered a case like this before, the screen either works or doesn't, the fact that the touch works and I have backlight puzzles me. No backlight or no touch issues are a common case to me, but this is a new one.
Can someone help here?
Thnx

It's a faulty LCD connector on the motherboard, in my case. Not the connector itself but the small jumper just above it, it gives power to the LCD, it was broken off.
I had it resoldered. Works fine now.

Could ju point me a bit closer whitch one it was?Did you get no image at all or something like the one on my picture?https://drive.google.com/open?id=0Bym65RPW_fIpeXlkX2NTYUw5SVk This is how mine looks like around the lcd connector.https://drive.google.com/open?id=0Bym65RPW_fIpTXZpWTFKby1Ua3c

No image at all, only black backlight ant the touch was responding.
The three square fuses on the bootom of the picture, it's similar in Z3, in my phone one of those was broken off.

Hi guys. I have almost the same problem but inverted. My display and touch is working but i dont have backlight. I can see the screen only if i put light on it.

Maybe u guys have a faulty digitizer responsible for image faulty(no image), better for send repair, flashing new stock firmware will not help

I tried with new digitizer, no luck. Tried jumping the fuse with no luck. Don't know what to try anymore.

Put the motherboard in the oven and bake it for a few minutes, it resold everything, if that's the problem, it will fix it.
For more infos and temperature / time, google it

Same problem here! i have tried new lcd, new flex cable. nathing works, lcd backlight turn on but no image, touch work cause i feel vibration while touching the lcd.
Pleas Helpppp Anyone with the genius mind??????

I'm facing the same problem with my Z3C, a friend of mine told me he applied this method on his phone and it worked but i'm not sure how to do it.

z3 no display but backlight on
by jumperig the fuse near lcd conector it turns on the backlight .There is another fuse surrounding power manager ic which may got open & display ic is not powering.
