My HTC Sensation wont turn on... properly.
When booting, i get a black screen. Around the edge of the screen i can see the backlight is on both when just on the battery as well as while plugged in, but i get nothing displayed, just ablack screen. It vibrates like normal when i power on, but nothing, black screen.
I do not belive this is software related however, because for all intents and purposes, the phone is booting just fine. However, nothing gets displayed to the screen.
For instance, when i call it from a different phone, it rings... and because i know where the buttons "should be" i swipe to answer the phone as i would normally, and it answers the phone, and i can hear and use the phone just fine. But again, NOTHING is displayed on the screen, i can only answer the phone, because my fingers know where to touch and slide to answer the phone.
Also, when i boot with VOLDOWN, i get nothing. So it doesnt appear to be a software issue, at least from what i can gather.
Im at a complete loss here, and really have no clue. I am very laman when it comes to hardware. I have opened it up (removed the tiny "void" sticker from a screw head, removed 6 screws, removed the lastic backplate (not the battery cover, the plastic plate that holds the battery), and just generally took a look at it. I really dont know what im doing here, so i havnt really done much further than this. Everything "LOOKS" okay, nothing seems out of place, broken, wires are all attached, it looks fine from what i can tell.
Theres no moisture, theres no residue, there what i couldnt consider excessive dirt or dust or debri (at least anything i wouldnt ocnsider normal after hivng the phone a year or whatever).... so im really at a loss here, and not sure what it could be.
Hoping maybe someone else ran into this problem and has had it resolved... but "search" and "google" hasnt turned anything up..Any help would be appreciate... Thank you in advance.
I just noticed, when i take the battery, an di simply make contact with the contacts, the backlight (the dim light around the edge of the screen, i assuming its the backlight) lights up. Pull the battery, nothing, toch the battery to the contacts, backlight turns on.... without ever pressing the phones power button or nothing. I do not remember this being the case before, and i would assume this would not be normal operation. With the phone not turned on at all (coming from a fresh battery pull), i just touch the battery to the contacts, or put the battery in, the phones backlight i wouldnt think, should come on and stay on like it is, no?
I had similar issue after my phone fell down face on. Had to replace the display unit to get resolved.

My Shift is not shutting off the screen like it should while in a call. I am sure this is draining my battery quicker as well as being annoying when I hit mute, speaker, or hang up with my face. Any idea what my issue might be?
Phone is stock:
Android Version
2.3.3
HTC Sense Version
2.1
Home screen widgets and icons...
Sense Clock with weather
People, WiFi, Battery (HTC Widget), Voicemail
Messages, Market, Flashlight, Camera
laid out in that order from top to bottom, left to right. I have only one other widget on another screen for Player Pro. Running Lookout.
Download "proximity sensor finder" from the market.
And once opened you should see it say 9.0cm. cover your finger over the proximity sensor (little circle to the left of speaker grill) and that number should change to a 0...
if it doesnt you need to take your phone to sprint
I guess it is broken. I covered it and it did nothing. It messed up a few times where it would work a little, then come back on now the screen is on all the time. I have resorted to pushing the power button while in a call to turn the screen off. Does the same thing I guess but it really doesn't matter much. I think I am going to get the Photon soon.
Thanks for the tip on the app. I think I will use it in the future.

No problem,
Although since that is just a defect that came with the phone, Sprint will replace that for free, without any problems.
(and tell/show them the apps responses if they do, they cant deny proof )
Just make sure you run the RUU beforehand if you do take it in and your rooted (but you said your on stock 2.3 so im assuming your not anyway)
Nope, all stock... I will look into returning it... it is a good phone and wouldn't mind it as a back-up phone.
Bump...
I still have my EVO Shift and the day before yesterday I did something to my phone to try and fix my led issue. It wasn't a major problem with it but something was obstructing the led making it hard to see when I got notifications. Well It started by me using a fine bristled brush to clean the little mesh earpiece screen with to clean over the led... it started to work and then made it worse. I then decided to just remove the mesh screen. I pried it out as gently as I could which made it easy to clean the obstruction from the led but as a very welcome side affect it also fixed my proximity sensor!!! The phone now functions fully again. So to all those willing to try it if your sensor is "broken" try removing the metal mesh part of the earpiece... just be very careful.
So today my phone fell into some garbage. I dont think there was any water, but after doing some googling, it seems that is one of the causes. After i pulled the battery out, the little circle is pure white but i do see a very little spot of red. Can anyone give me any tips? If its ruined, can i easily replace it? I just got this from ausurion a few months back. I dont really want to have to shed out another 200 for another phone. I put it in rice for the time being just in case.
I can turn it on, and it vibrates normally, and it vibrates when things happen. The bottom icon lights also turn on. So, just imagine your phone working, you just cant see anything.
EDIT: Also, i cant get into fastboot, recovery, etc because it is only blank. Should i be looking into a new screen?
If there's water damage, it might be a lost cause, but if it's not, replacing the screen would be a much cheaper option than shelling out $200.
It isn't anything to do with water my phone did the same thing. You damaged the wires going to the screen. Touch still works right. Do you have insurence?

There are many different causes of problems. You can't be positive that it isn't a certain cause.
Hey guys, i'll try to explain the situation as best i can below, hopefully someone can work out what is wrong.
My phone is about 16 months old. About 2 months ago i dropped it twice within the space of a couple weeks. There were a few cracks along the screen, however it wasn't very noticeable and i wasn't going to bother having it fixed. The problem started a couple of weeks ago when i went to grab it out of my pocket, however i found out the screen was black and it wouldn't turn on. I don't really know how to describe it but it was acting very strange...
- The screen would have white/gray bars all over it then turn off, then it would do the same with very thin vertical lines that were white/gray/other colours...
- When i get the screen on, it generally turns off again within 30 seconds, however it can stay on for a few minutes.
- If the screen is on and i press the lock button, it almost certainly won't come back on.
- Restarting the phone or holding the power and volume button nearly always gets the screen to come back on. It often then restarts but turns off again shortly after.
- The phone is otherwise still working when the screen goes off; the notification light stays on and i hear messages etc coming through
- The backlight often stays lit, revealing a gray screen opposed from total black. Sometimes it does not stay lit however.
- When the screen came on it was often unresponsive to touch
I had the screen replaced yesterday by a phone repair shop and the phone is still not right. I have factory reset the phone and also wiped the partition cache. Other than that it is still not working. IT seems to be working better... The screen always seems responsive to touch when it is on, and it doesn't seem to be turning off as often. It generally starts up and works fine when i start up by holding the power button and down volume button together... However even still it sometimes just flashes up with a few thick white/gray and black lines on the screen..
Does anyone know what can be causing this and how i can resolve it? If you need any more information please let me know and i will try provide it. I could try get some pictures of what the screen is doing when i finish work. Thanks guys, i appreciate any input.
EDIT: I managed to get a pic of what i mean by the thin vertical lines all over the screen. This just appeared when i tried to restart the phone after it the screen had once again stopped working. The imgur link is gIFMGD6
Anyone have any ideas?
Hey, did you ever figure this problem out? My phone just started doing the same thing. Can't find much info about it.

Yeah, i had the screen fixed hoping it would fix it, however that didn't work. Turns out it was the motherboard, don't know what was wrong with it in particular other than it was simply going faulty. Had someone replace the motherboard on it for $50 and have had zero problems since! Hope that helps you.
Thanks for the response. I tried replacing the screen too with no luck. Unfortunately the same place that replaced the screen said it would cost $400 to replace the motherboard!!! The phone cost less than that so it looks like I'm gonna buy a new one.

Hi,
I have this really weird stuff going on with my Nexus 5 screen. I cracked it a couple months ago and bought a legit replacement screen for it and installed it myself (glass, lcd and frame). I fixed it with good instructions and it worked properly for two months. However though, now when I take it out of a pocket and try to turn screen on, sometimes it just doesn't light up. It's still on and every button works but the screen doesn't turn on. I have to give it a light tap or two on the back in order to make it light up again. Same thing happens sometimes when I'm using the phone normally, the screen just goes black and goes on after tapping it couple of times. Otherwise the phone works normally like it did when I bought it two years ago and after running couple of tests with screen, everything seems to work from touch interface to the graphics card.
Tried looking it up, no results.
I've noticed that the front camera doesn't work for some reason (probably just broken) and the battery lasts in use only 2-4 hours which isn't that much of an issue since I'm looking for a new phone. I just want this one to last long enough till I buy a new one.
It comes up when tapping the screen or power button? It could be a power button issue.
The screen comes back on when tapping the screen or the back of the phone. The power button isn't the issue. The screen just goes black but nothing else happens. It doesn't turn off or go to sleep mode.
Strange issue. I've never experienced it and any problems I had were related to the power button.
Could it be a loose connection inside the phone? Maybe an issue related to the proximity sensor?
Thats actually what I've thought. I have checked the phone's insides twice and didn't see loose connections, and the problem feels like it's related to proximity sensor since the screen going black happens exactly same way that when calling someone or doing something else where proximity sensor shuts the screen. It's really weird though...
Huh, I took backplate off and unscrewed the motherboard cover and took everything apart and rebuilt it and now the problem is gone. Seems like there was just some bad connection somewhere.
Glad you got it to work without having to pay someone to fix it
So i've been having a lot of issues with my N5 lately, mostly small stuff like general slowness, poor battery life, not surprising on an almost 3 year old phone. I also lose cell service way too frequently (not an issue with my carryer, all my friends are on the same network and are fine). Camera won't focus anymore (though im pretty sure this was my fault, probably broke it while taking it apart). I'm pretty sure the battery connector on my motherboard is damaged. I've had many problems with the battery reading its temperature as -30 C (battery heath "cold"), i've replaced the battery 4 times now and i still get that problem every now and then. Pushing on the connector fixes it temporarily, so im pretty sure some pin is bent slightly out of place and i don't know how to fix that. It recently started having this issue where just moving or bumping the phone the wrong way would cause the phone to shut off. Probably an issue with the battery connector again. I tried fiddling with it but it didn't do much.
The other day i turned it on and the LCD was backlit, but black except for one single vertical white line. Rebooted and it looked normal. Few hours later i got really pissed off with it for shutting off in the middle of an important text and threw it at the wall (not the best idea i know). Screen was already cracked so i didn't really care. Ever since then the LCD has been a real pain in the ass. i can turn the phone on but there's nothing on the screen. Ii get haptic feedback when the Google logo would up, and the notification LED is flashing like i have a message. The backlight is on and pushing hard on the cable connecting the motherboard to the daughter board i can see it start to turn on, (Google logo, few seconds of boot animation) but then back to black (while still backlit).
I can post photos if it would help diagnose/fix this, my phone is my main camera and i don't want to bother anyone if i don't have to.
Anyone know any tricks that might squeeze another mouth out of this dying phone? Any response is appreciated, Thanks!
The issues could have been related to the power button or physical internal damage. My suggestion: replace the screen with a cheap 3rd party screen if the internal components are still working. This will give you more time with your existing phone and allow you to have a working backup.
