Sensation screen unresponsive for short time after turning on

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.

[Q] Screen Doesn't Work, Strange Pixelation

So I searched everywhere and can not find ANYTHING on such an issue...
A little history on my phone, previously cracked the digitizer but replaced it with no issues (except for a minor cosmetic scratch on lcd, barely noticeable) about 3 months ago, has run fine since then, never any issues
I am running ICS under HD sensation rom, never any issues
I occasionally had some touch screen unresponsiveness, but a quick turn off and on of screen would fix this, a pretty common issue for this phone
The Issue:
today for some odd reason my phone screen would turn on and would be just random pixels of varying color, not correlating to lock screen at all, a reset of the phone did nothing for this, but strangely enough pressing very slightly across the whole front of the screen would return it to normal, if a bit briefly, so i concluded that a wire connecting the screen had come loose, or there was dust inside the phone, so i took it apart and made sure everything was a-ok, which it was, but after putting it back together the same issue persists, and has in fact gotten progressively worse throughout the day, it is now to the point of being unusable, has anyone experienced anything similar, or does anyone have any solutions? i would rather avoid a new phone if possible...

AnyOne??
I'm also having the same problem with my HTC Sensation and tried the master reset and inserting a new SD Card. Did you figured out what was causing the problem? I appreciate any info.

Screen dying

Hi guys, I was just wondering if anyone else has experienced the same problem as I am.
Basically a few months ago I noticed a little white line in the middle of my screen. I ignored it until the point that my touchscreen stopped responding.
I sent my phone back to HTC and I got a new screen.
I saw this morning that this problem is back, I will be sending it back to HTC but I was hair wondering whether this has happened to anyone else and what the cause of this could be.

Are those lines dead or stuck pixels? I have an itouch that had similar symptoms, the lcd was showing lines of green pixels, the touch stopped responding, it got extremely laggys so i opened it and without the cover i holded it in my hand, voila. Since the sensation also has a similar problem with touchscreen i guess its caused by static and gronding that could also affect lcd, holding it without the cover makes the trick for me, you should try the grounding pin fix.
My 2 cents.

[Q] Toshiba Excite 10 flashing screen.

I've got an odd problem with my Excite 10. A few weeks ago it started acting funny. What happens is every once in a while the screen will flash off and then back on again. When it does that it messes with my system, I have an app locker, and it re-locks the app when the screen refreshes, also, I'm trying to use an emulator that works with a bluetooth controller, but when the screen flashes the connection to the controller is lost, just as if I had gone out of the app and then back in. I'm running the latest OS as of this date, and any help would be appreciated.
Thanks,
TechPlease

google your phone and issue, and see if anyone else has your issue with current update.
if you think its hardware problem go to your provider and tell them the issue.
or you can go to ebay and order the LCD if you think the screen is responsible... dropping a phone can hurt the delicate ribbons inside... does squeezing different spots or shaking your phone cause any issues?

Fuzzy screen?

So, I just recently got this 'fuzzy screen' problem (again). The first time I got it, my phone would randomly do it and I'd have to reset it. I still got messages and calls, as I could hear the ringtone but this (see pic) is all I can see. Eventually my phone started flickering on/off randomly, then the 'lcd' just died. So I replaced the lcd and the phone still didn't work. I ended up replacing the flex cable and it fixed the display issue. Now, I'm getting the fuzzy screen again and hoping it's not going to do what it did last time this happened. Do you guys think it could be my flex cable that's the problem? Or maybe the motherboard?

30% you have "little disconnected" flex cable from the board
50% broken flex cable
20% display
first check connection

Hi there, I had this when running CM10.1 just after the mSD card failed to read. I rebooted a couple of times & still the same.
I booted into recovery (where the screen worked fine) & flashed back to stock. Been fine ever since, mSD works fine again also.
Were you running a custom rom?

This problem was solved a long time ago, so I don't know what to tell you.
