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.

Desire S is turning off

Hey there, ive got a problem with my Desire S.
I bought the phone about 4 weeks ago and the first two weeks everything worked fine. But since the last two weeks, the phone is turning off itself randomly. I am sure, that its not a software problem, because I flashed the standart RUU Rom before but it turned off again. Also i checked the battery contacts and the SIM contacts, both are okay.
Maybe some other hardware contacts arent fitting?
Excuse my bad english, I am from Germany^^

Same problem
I have the same problem.
And it's definitely not a software problem...
And I've realized, that when I press the battery cover on the right and left sides, it turns off. And mostly it also turns off when I have my Desire S in my pocket.

Yeah mine too, sometimes I pull my phone out of my pocket and I see it's off. I think that's not a software issue, changed several ROMs but always the same problem. Fortunately it happens seldom.

I remember that someone else experienced this and fixed it by putting a piece of folded paper behind the battery to guarantee it's connection didn't fail

Try putting your phone on one palm (face up) and then tap it with the other, just like if you were claping (with reasonable force) Does it turn off? If it does, a had a same problem, and its definitely problem with battery contacts.
Put some isolating/electrical tape around bottom part of battery (just one layer, all around), and about 1cm above. Just make sure that tape is thin enough, so the battery can still fit in. This should also solve creaking battery cover
Good luck

Hey, i tried everything, you said, but nothing fixed the problem. I think, the battery contacts are ok, becuase i fixed them with a little piece of paper before.
Also, i tried this trick with the clapping in your hand, but then the device is still on.
I read a thread about a similar problem, there was a broken battery the problem, which got under a high temperature or has voltage problems.
I contacted HTC and they say, that i should try another battery in my device, which the gonna send me soon.

Fixed

I do confirm! It works

Desire S in pocket shout down Fixation
OK i did a sketch of Desire S with google sketch book, For who can not fix the shutdown problem.
1th we need 2 piece of paper NO#1 and NO#2.
NO#1 will locate between battery and that back cover.
NO#2 will locate between the batteries bottom and top of that plastic lock (it makes more force to push the battery forward to the pins)
Details:
The papers must be 1 mm (or lilbit less) in thickness.
For what i used
NO#1= 3.5 x 5 cm
NO#2= 0.5 x 3.5 cm
GL HF

same problem and the solution
Hi
I had my wife phone with the same problem.
It is running with the venom rom and the rom is dream, but the problem which
is described earlier, kept coming .
After reading about the battery solution here, I think the problem solved.
I will check for the next few days
I want to thank you all for finding the solution
Thank you
Avi

[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.

[Q] Screen drop outs and now always black, why?

Hi guys,
my DS did some strange stuff lately. It began with the screen staying black when I woke it up (hardware buttons did turn on and touchscreen also worked). I thought it was a software issue, because after a few on and offs the screen usually worked again. Also, this never happened when the phone was charging.
But a few days ago the screen never turned back on again, even when charging. I got a new battery but still no change. It won't even turn on when booting or when going to fastboot/ hboot.
Does anyone have an idea what is broken? I think my best guess is to have a look at these other screen replacement threads, but I wanted to ask first because the screen seemed to have gradually become broken, which confuses me. I didn't think something like that was even possible. Also, I can't return it since I bought it used and in Germany (DS is USA exclusive).
Thanks for help

Most certainly hardware as it is black when in bootloader and ROM. Best guess is the LCD but could also be the main flex the likelyhood of any thin else is fairly small.
Do read up on the screen replacement threads as this phone is one pain in the ass, you also need to be aware of what LCD to buy as there were different ones and they are not compatible.

Thanks for the tips. Screen might be still ok since it went out gradually, could be a defective contact since it also went on and off randomly. But I guess there is no way to only replace this contact, too complicated to find out... I will see.
Yeah, I had a look at these threads already, thank you

I had a program that I moved to the sd card that would cause the screen not to come on and would have to do a battery pull. When I moved the app back to the phone, the problem stopped.
(Walgreens app)
It has happened again since, so it may be another app I have to track down. Or I may be looking at faulty screen trouble too.

even if an app on sd were the cause of this it certainly couldnt make the screen blackout while in recovery and bootloader mode. to the best of my knowledge it has to be a hardware fault if screen wont turn on in bootloader... but well ive been proven wrong in the past

Well since I had problems with the screen turning off before when it did work in recovery, there might be a connection to daswerk's case. However I kept all my apps on the internal SSD and do remember checking it. Also, my screen turned back on sooner or later or when I played around with the keyboard.
However later it was off even in recovery mode. I did disassemble my DS lately (and broke my screen like seemingly everyone else hehe) and am now waiting for my new LCD screen to arrive in Germany from the states haha. Shipping costs were higher than LCD costs, d'oh! Thanks again demkantor, you've been helping me indirectly with your posts in the other threads as well

So guys, screen arrived, reassembled my phone, switched it on aaand... black screen.
Graphic chip or motherboard may be broken. I'm thinking about a loose connection because screen turned off once in a while before it never got back on. I found a user by coincidence here on xda who reported the same problem.
Any ideas are greatly appreciated. Don't want to forsake my dearly loved DS :'(

Next most likely would be main flex cable

Are there other possibilities as well? I'm thinking about getting a whole replacement set so I can try everything shipping costs are high since I live in germany hmmf
btw, digitizer/ touchscreen doesn't seem to work either, is this another sign that main flex cable is the prolem?

There are always more possiblities I was just letting you know what I would replace next as the most likley cause.
Having multiple phones to exchange parts is a good idea and really about the only way to test different components
And yes have no digitizer working can be a sign of a bad flex as well

Phantom touches appearing on screen

A couple of days ago my phone started not responding properly I have been using viper 3.1.2 since it first came out I am s-off with updated firmware and radio with 4-ext. It doesn't appear to happen when in recovery but happens randomly mostly on the left side of the screen sometimes just one or two touches but quite often there is five or six touches on the screen. I have tried the foil trick and discharging the battery and charging trick and even downgrading firmware and radio and installing a different Rom and nothing seems to fix it. Does anyone have any ideas or do I just need to get my digitizer replaced. It is just wired that it doesn't happen in recovery just in the Rom. Thanks in advance for any help.

Either that, or try changing the phone. There's probably dust underneath. If digitizer is expensive, try pulling it out, give it a personal service like dusting and vacuuming(make sure you dont vacuum some of the easily loose part out. I did that with a small portable vacuum, works like a charm.

OK thanks I will try that

So I can try to clean the surface between the digitizer and the lcd panel before getting a new one ????
I already try "the FIX" but it fix nothing on my phone, so I decided to buy a new one from ebay, not the original but the one of XE edition, I hope that the constructor made it better than the original one ...
