I dont like starting a new thread but I have looked as hard as I could. I apologize if this has already been covered.
Basically I have an HTC Sensation which has this strange SPLIT screen thing happening. The screen basically is shifted up, wraps around the top and ends at bottom of screen. Best way to explain it is to just show pictures of the screen(pictures attached)
This behaviour is consistent in bootloader, 4ext recovery, htc bootup logo and in multiple roms.
I have tried Revolution 6.6.4 before returning it to stock 3.32 ROM where its now in COMPLETELY STOCK state. Touchscreen registers touches but at original position where items should be before being shifted up, so basically I have to touch about 100 pixels below desired icon/screen elements (but entire screen does register touches)
I got this phone from a friend who has no clue how he got it this way (but he was messing about with roms and running virtuos inquistion 4.0.0 when I got it)
There seems to be no damage to screen anywhere and everyhing works like it should except being shifted up. Phone has never been dropped etc
Anyone have any idea what/why this is?
If I had to guess, it sounds like something is loose which connects the digitizer and the ribbon? When three connection is loose on a computer monitor, the same/similar results occur. You may need to bring that into a repair shop

Close, but it's more likely related to the LCD. Digitizer is only the touch-sensitive portion, the LCD is responsible for image output.
Update
Thank you for your help both of you.
It was indeed a hardware fault. Sent it in to HTC who fixed it under warranty
Thank you again
Awesome, glad to hear it!

I have just replaced my digitizer (was dust under the screen and also a scratch on the digitizer itself, along with the fact I damaged it removing the sticky tape) and the whole screen is almost completely unresponsive. Brand new, but wont work fully until I touch the screen for a bit or give it time to sit after activating the lockscreen.
Once it is through it's "warmup" the screen works flawlessly. It just acts like a slug before that... Also rendering the quick launch lock screen completely worthless. Anyone have any ideas what could be the culprit?

I too replaced a broken screen on my sensation, and i am experiencing the exact same problem as you. Only for me it's only the lower left part of the screen that 'takes time to warm up'.
Did you find any solution?
Not yet. I have another digitizer on order, and fingers are crossed. If not, ill be biting the bullet and waiting for the nexus prime. I have this feeling that it is something other than the digitizer which is extremely sensitive. If people are claiming responsiveness issues after a week or two of use, and while on their sixth or seventh sensation... It sounds like something is slowly deteriorating or building up.

I don't think it's the digitizer either, probably something else ont he phone. However i don't think it is the same problem as everybody else is having, since they experience their screen being unresponsive in general rather than just after turning on.
I am though going to try some of the fixes suggested, i.e. improve the grounding by placing some aluminum foil under the cover and see if it helps.
What does "turning on" mean? Cold boot up? If so, then the CPU on the phone will be busy doing stuff. If you mean waking up from sleep, then that's another problem.
for me it's both cases, both when booting the phone and just when turning the screen back on. What's strange is that it is only the lower part of the screen that's frozen :-S after 10-20 seconds it suddenly springs back to life just as nothing had happened and works flawlessly until i turn the screen of. Then i see the exact same problem again.
I also noticed now that the screen also freezes after calling somebody and when you hang up :-0 I really don't know what is wrong with the phone!
If the phone is unsecured (never sleeps) it will work flawlessly. As soon as I click the top button to secure the screen, or take a phone call, once I try to unlock/ use the screen again... The problem comes back. The left side of the screen is the most responsive, usually moving my finger around for about five or ten seconds will restore full sensitvity. I received a new digitizer in the mail, just waiting on tape. Interesting note; they are different digitizers. The original was HTC/ tmobile brand while the replacement is simply HTC. The ribbon cable also reads different. My original: pyd v1.0, sw-10 94v-0, e3082521117. The new one reads: pyd v1.0, e21954-1, ruICACichia, 94v-0 1112. The current digitizer replacement is also a standard HTC label... I wonder if it is because it isn't a specific model replacement.

Alright so i tried doing all the fixes related to the grounding issue, and i didn't affect anything at all.
I'm going back to the repair shop today (have a three months warranty) to tell them to have a look at it again and see if they can fix the issue. Maybe they have a spare digitizer they could try instead of my current one. I will let you know if anything helps!
Sounds good. I am betting its either an incorrect digitizer for the model of phone (us/eu/whatever) improper mounting or damage, or just planetary alignment or something equally stupid. I'm really hoping someone figures out this problem... It is frustrating to spend more time figuring out how to fix a phone than you actually do using it.

True, had i known from the start i would probably just have bought a new phone, rather than spend on the money on getting the screen replaced :-S
Well, I replaced the digitizer for a second time. Seems to be the same thing so far. Different initial responsiveness spot (looks like the right side might be more sensitive now) but I didn't have high hopes. I wonder what it could be...

So i went back to the repair shop and got it fixed. I guess they weren't in the mood for scientific inquiry, because they simply disassembled the phone and installed a new digitizer. After that everything is working fine, altough i will never know if it was the digitizer itself or some faulty wiring somewhere :-S
Worked for me
I have had exactly the same problem you all have experienced. The first digitizer I ordered from a company on e-bay gave me huge problems at the unlock screen. Bought a new one from skalshop and it works perfectly. I even tried it without tape to make sure it worked before I glued the thing together and it worked perfect.
I dropped my Sensation while on vacation in Key West. I arrived home and bought an HTC OEM digitizer. It came, I put it in and now when I unlock the phone the screen lags for 5-10 seconds and then it is perfectly normal. It will lag that long also if a call comes in. Hard to answer it sometimes. But then it is fine until the next time I shut off the screen and put it back on. If I leave my display on all the time it is fine. Only coming back from sleep. I am in IT, A+, Net+, Sec+ and MCSA certified. So no problem with changing it, it went fine. Any idea what it could be?
You sure it's OEM. I think you bought ebay stuff that is from china. You get what you pay for. I would try to flash another ROM just to be sure.
Also download z-devicetest from the market and check out the screen specs.

I replaced my digitizer and I currently get incredibly annoying unresponsiveness every time I unlock the screen. Very frustrating. Also, it seems to only have zero response on the right side. The left side (with the phone quick launch) will move after fidgeting with it for a second, and then the rest of the screen will follow suit.

sounds like the EXACT problem i had with an TMOUS 1024mb HD2, replaced digi with the one from a EU 512mb HD2
its a hardware conflict between varying models, and these hardware revisions may have spilled into HTC's latest gen of devices
Hello people on XDA!
I hope anyone can help me out here
I broke my glass on the phone , and I got a new glass installed over the old LSD screen, by an prof. but the new glass with the old LSD could be calibrated together, then he did it, and it works after that.
After some time, couple of weeks, the right side og the screen dons't work proppely.. When I turn on the phone there goes around 20-30sec before the right side can be used, but after that its works perfect!
Its allso when I turn on after the screen have been off (lockscreen) its the same, 20-30sec the it work, otherwise its dead
Remeber there is a picture(The LSD allways work), but no control at the right side of the screen
I have tryed allmost all RADIO's and so on!
allso tryed the ground pin and the back cover.
I have tryed everything I could fine on the web, so now I need help!

Your phone has an LSD screen? Whoa. Jk, sorry man, it's most likely that the screen is installed wrong, nothing any radios could fix... Maybe take it back to whoever installed it and complain?

Maybe its the LSD screen that's why it isn't working properly

Take it back and have them correctly install the screen. Do it soon while its under watentee and don't take no for a answer, they messed it up they need to fix it properly! Best of luck. Reinstallation is the only option at this point. Nothing else will fix this issue. Sorry.

Sounds like your CPU had a stroke...
Hi guys, I am wondering if anyone could help me diagnose a problem with my old phone.
I have an old HTC sensation XE and it was thrown on to the ground hard and since then it has not worked! I Have since moved on a got a new phone but now i'm trying to resurrect it.
It doesn't power up nor does the indicator light come on when I plug it into the charger. There are no viable signs of damage on the screen.
I have opened up the back and had a quick look around. Again no obvious signs of damage to the chips inside.
I though some of the connectors may have become dislodged and fiddled around in there for a bit to no avail, though i did manage to inject some life into it, though it was a white background and some black lines through it.
I powered the phone down and since then I haven't been able to replicate this.
Ok so does anyone think this is repairable? and if so how can I go about fixing it?

I will try that when I get home from work.
I was under the impression that it was a hardware issue as this occurred AFTER being thrown on the ground. Or was I wrong?
It could be a hardware issue, but you could always try the unbricking project. Since you "injected some life" into your phone, you may have hope with the unbricking project

Not sure what to do. Happened about 2 weeks ago and getting progressively worse. Sometimes screen unresponsive, sometimes ok, and other times registers a touch in a completely wrong place. Is my digitizer going out? Will flashing different rom or kernel work? Currently have an xe s-off with elegencia rom

For me the cause of this was certain apps running in the background, Any.do and the new Skype update with it's new UI, seems there's a problem with custom roms and some apps UI, just like watsapp sometimes causes typing issues on custom roms, stopping or uninstalling solved my problems.
Haven't reported it with to CM team tho, when I get to ten post count.
thanks for the ideas guys, but I think that my digitizer is shot. turned on touch overlay and pointer location. seems like the screen is warped. if I put moderate pressure in the middle of the screen, it will register 5-8 differet touch points across the center section of the screen. sometimes if you drag your finger, it will skip or not register certain areas(mainly the center of the screen) I'll try get a screen shot later.
Take the back cover off your phone. Along one edge of your phone there will be a little metal square with a nipple. Add small folded tin foil to the nipple loosely then put the cover back on. Your screen can now ground probably. This problem is more noticeable when charging.

Hi i bought a sensation and it had the wifi problem and digitizer problem (going crazy) and i searched for 2 days and got nothing, i also read that putting tinfoil over the silver nipple thing would fix it but if anything it made it worse. tried bout 7 different roms, everything was still the same but now i have perfect wifi and digitizer, fixed it last night and not 1 problem so far. So.. what i did was got an old digital camera card, cut off 4 of those metal pins (look at pic) put 2 next to each other using strong double sided tape and stuck them to both connector pins on the back battery cover, now i got perfect wifi. The connectors on the battery cover r just conductive paint and wears through to the plastic over time (i also tried condutive paint but didnt work). And the digitizer i cut a piece of plastic/rubber off an old usb cable (see pic) round the wire and fitted it over the silver nipple ground pin thing and now my digitizer works perfect, not one problem so far. Give it a try, assuming ur digitizer isnt actually broke.
My problems also started reoccurring and it doesn't seem to be software related, cause even when it's completely stock people reported freezing and lock ups on this and other HTC models, I hate this phone and will never purchase another HTC product.

I recently took mine apart to clean dust from under screen and refit the old digitiser. It was unresponsive and some parts of the screen didnt work at all so I flashed a calibration file which improved it but still working 100%. Took apart the phone several times to check connections, reinstalled several roms, calibrated screen and cleaned contact on the back cover etc...nothing worked.
I use the trace keyboard a lot but couldnt with this problem. I was sure I had damaged the digitiser and was losing hope until I upgraded to firmware 3.33.401.106, hboot 1.29.0000 and radio 11.76C.3504.00P_11.29A.3504.18_M. hboot from 1.27.1000 and screen is now working as normal.
I ran CM 10.1 JB and Viper 1.63 before removing the digitiser and after refitting it flashed CM JB, Inspiration, ARHD and currently on viper 3.1.
I have seen a high number of posts recently about screen responsiveness so could it be an issue with 1.27.1000 on the latest roms?
I cant understand how this happened straight after removing the digitiser and was fixed by flashing newer firmware.

Thanks, flashed it last night and seems ok so far, will give it another day of two
Sadly my problems are still persistent, tired every possible solution including the grounding pin fix from another post which spans over 50 pages long, also trolled the Internet only to find this is not an isolated problem, other people who own the HTC sensation have been having the same telltale issues and quite frankly I've come to the conclusion that this is just another half broken HTC device HTC decided to release to cut corners on just to save on overall production cost.
