HTC sensation XE not turning on and no charge light

So today I was using my phone and then i could turn the screen back on. So i pulled out the battery and tried to turn it back on, however it didnt work. I tried plugging in the charger, but there wasn't any orange charging light (it was on around 60-50% battery when it stopped working). I tried connecting it to a pc, but there was nothing, i couldnt access the sd card and there was nothing on the device manager. I tried doing the volume down and power button and other stuff, after a while i managed to get the phone to boot up but it died before it made it to the lock screen (not charging). Is there away to fix it?

Try removing your battery and then plug in the cable connected to PC USB. I would also try doing the same with a unix based system, just to be sure that there are no driver issues(though windows should at least show an unrecognised device in device manager).
Also, can you keep it on charge for some time and see if the phone feels a bit hot...? If not, it seems to be hardware fault.

Maybe your phone is bricked,but the way you explained it seems like a hardware problem !
Do you have warranty ?

Power,Volume and camera buttons have all stopped working... and now the phone is off

The title is pretty self explanatory. Noticed when i woke up that neither the power, volume or the camera buttons work. They still clicked when pushed but no function beyond that. The phone its self still worked before i pressed the yellow reset button next to the sim card slot. when i pressed the yellow reset button the phone vibrated and turned off, never to come back on. When i plug it into a charger it still has the LED light except its off so i cant just press the power button to turn it back on. When plugged into the computer, then computer recognises that a device has been plugged in (makes the dun-duh! sound) but the phone is not recognised by either the PC companion or Sony EMMA. Same deal with pulling it into a mac. The Sony mac companion program pops up automatically , it says it does not have any device connected, despite it popping up when i plug my phone in...Ive put adb on my computer and tried adb reboot but again it does not recognise the phone while its off. Is there anything i can do to fix this phone or at least turn it back on? I've spent enough on getting this phone prepared as it is so a DIY fix would be great.any help at all would be much appreciated, thanks

I too am having issues while restarting my z3 after switching power key does not works.
It boots only when I connect it too my pc (still dead) and then press the yellow button(try the yellow button before connecting the pc too),but all the hardware keys works perfectly except the power which is just functinal.

No luck unfortunately. When i plug it into the computer the Sony logo pops up and goes to the charging screen. When i press the yellow button just after plugging it in it just restarts and does the same thing. Thanks anyway

That's exactly what happened to my phone last time,managed to get it started after some random trials ( it started using the normal power key after removing it from pc & letting it rest for some time)
Keep me posted if u manage to solve it.

Will do, I've gotten in contact with the sellers and they are happy to inspect the phone for warranty claims to see if I've done anything to it to trigger the breakage, so ill be sending it off tomorrow . You may not be able to answer this but i might as well ask, I got a whole screen replacement for the phone a few months ago as i had dropped it and the screen had smashed etc. The screen replacement all went well. Do you think the re sellers will know/care that the screen has been replaced? Will it impact upon my warranty claim? I don't plan on telling them I've gotten the screen replaced but I'm just worried they'll find out and say my warranty has been voided.

I replaced my phone's speaker from 3rd party,right after that I am having problem to restart the device.
I think Your warranty is probably gone.
Try to flash Ftf file,i didn't cause I don't wanna loose my root.(changing between roms help a bit)

when you open the phone and remove the battery, you can see like some flat wires. those connect all your buttons, screen, loudspeaker and other things to the motherboard. I'd say that the problem is in this flat wires if the buttons do not work. It can be changed but don't try it if you do not have some practical skill since the z3 is not really an easy phone to repair, it's all glued >.<
ps.
this is what i'm talking about, to be clear: http://www.ebay.it/itm/FLAT-FLEX-TA...008493?hash=item2c9efe04ad:g:4QkAAOSwyQtVt5MY

My HTC U11+ is dead (hardware?)

My U11+ was wet under the rain, the touch panel has stopped working and even the LCD panel has started to give problems, I sent my phone in assistance but it was not repaired because of water infiltrations even if IP68...
I repaired several phones in my life so I decided to replace the screen, I made a complete and careful teardown (can't find videos or tutorial for this phone) and I installed the new full screen (lcd + touch + glass).
Now if I connect it to the power supply or to the USB the battery icon appears on the screen and the LED lights up but if I try to turn it on nothing happens, I can't even go into recovery or download mode and the PC doesn't detect the device.
Analyzing the situation it seems that the screen and battery are correctly connected to the logic board as well as the type-C port. To my eyes it seems that the power annd volume button are not connected via flat cable to the logic board but through 4 contacts at the bottom, I see no traces of oxidation or damage to the contacts, any suggestions?

After Battery Replaced, Screen dead?

My phone's battery has been bad for a while now, and its just been sitting in a desk for about a year. I replaced the battery since my sister wanted to use it and upon turning on the phone again, I am getting screen feedback but only in the form of a black screen. I don't see any bootup screens, even if I try to go into recovery mode. Once again, the screen still lights up black if I do things like plug in the charger or press the power button. I've reseated the display cable and battery cable but to no avail. HiSuite recognizes that it's plugged in (although I can't do anything because HDB is disabled). Anyone have any ideas on why the screen is dead?

Make sure all connections are firmly connected.

Black screen issue, i can't restart the phone

Hi! I'd like some help.
I have a Samsung Galaxy S10e (SM-G970F).
The power button is faulty, I got it back from service yesterday, unfortunately it was not repaired because the device is rooted.
Before I handed it in for service, I was able to turn it on without the power button (download mode -> restart), but now the download mode is not available either.
And it doesn't indicate charging either, the display is completely black at all times.
Yesterday the computer recognized it as a drive, but it showed only one TWRP folder. Today, unfortunately, the computer does not even recognize it, nothing happens when the usb cable is connected.
Is it possible that the device has remained in some service mode?
Somehow I would have to reboot or get into download mode, I just don’t know how..
So now:
The display is completely dark.
It does not respond to buttons.
The power button is broken.
It does not indicate charging.
The download mode does not start.
The computer does not indicate a usb connection.
The adb doesn't see either: error '(null)' not found.
What can I do?

Probably is bricked by the shop you leave to repair, get back to them

Thanks for the suggestion.
I can't go back to the service now, I made a complaint in writing before yesterday about this, the investigation time is 30 days.
However, I have new news about the device.
I realized that the device itself works, only the display is always dark.
I disassembled, unplugged the battery from the motherboard, and switched back to download mode and Odin recognized it.
I managed to update the software on it, the device restarted fine, only the display is completely dark.
The computer already recognizes it, I can give a command via adb, and I can hear the volume button when pressed.
The only problem is that there is no picture on the display.
I reconnected the display connector to the motherboard, but that wasn't the problem.
When the power is off, the display does not indicate that the charger is connected.
Does anyone have any idea what else I can do?

Try this command (It toggles the display on and off ):
adb shell input keyevent KEYCODE_POWER
