Backlight Won't Switch Off. - P3300, MDA Compact III General

I dropped my XDA Orbit the other day, and ever since the backlight and the blue scroller constantly light up, and whenever the phone is restarted the Bootloader screen shows up, and the only way to get the phone to boot is by using the hard reset buttons (the phone then boots up normally and all data is still there). Do you think this is a warranty job? Or is there any way to fix this?

Desire won't boot

Any problems with the Desire anyone?
Got mine last night, put my SIM in and charged it for four hours, turned it on and can't get to do anything with it.
I'm on T-Mobile and get a pink circle solid pink trailing off (I,m guessing this maybe chases itself around like the busy cursor in Vista) then it shows the htc splash screen, white background with htc in the middle in green letters, this stays a second then goes off for then the splash screen again for a second then off for two etc., you get the picture. That's all it does, will not turn off you have to take the back off and remove the battery, tried rebooting several times and always the same. I put it back on charge overnight and tried it again this morning and the same, left it on for about twenty minutes to see if it should do this for a while and the phone and screen get quite warm.
Well hacked off!! Can't even take it back 'cos it's Easter Sunday and everywhere is shut!!!
Anyone had similar experiences?
As I can't reset via the phone software I did the phone button one, see below, still with no improvement. Mine is going back tomorrow.
Performing a factory reset using phone buttons
If you cannot turn on your phone or access the phone settings, you can still perform a factory reset by using the buttons on the phone.
With the phone turned off, press and hold the VOLUME DOWN button, and then briefly press the POWER button.
Wait for the screen with the three Android images to appear, and then release the VOLUME DOWN button..
Press VOLUME DOWN to select CLEAR STORAGE, and then press POWER.
Press VOLUME UP to start the factory reset.
Cheers.
wow seems odd, usually if ts defective it wouldn't show you the boot screen even. but this looks like a software glitch, somehow, .. but again, if its software than you shouldnt be the only one experiencing that
thanx for sharing, .. , hope you can get a replacement ASAP
Other users seem to be experiencing the same problem, I've had a look on the T-Mobile forums and it's reported there.
Sorted, swiftly replaced this morning, this phone is awesome!

Screen not turning on

Ive had this issue for over a week now. Often when I need my phone and turn it on from the Power/On button at the top, the screen stays black, it doesnt turn on. I can see the bottom hardware buttons light up and the touchscreen seems to work, I can feel the haptic feedback when pressing the screen... Assume its a connection issue - anyone had the same problem?
I have the same issue, but just turn the lock on again (hardware buttons turn off) and unlock the phone, and then the screen comes on.
Help!
This has gone really bad now! Ive tried find help on the net, but nothing so far!
I have removed the SD card, Sim. Tried with and without. I have hard and soft reset the Desire severeal times. It works well for a while, but the problem kicks in sooner or later.
Pressing the power button the buttons light up, the screen vibrates but its black, not turning on. I tried to unlock it, but without any help.
Hate to take it to T-Mob and be without a phone for another 2 weeks...
Im trying to make a hard reset by pressing the volume down + power (also the alternate press home and back and then Power). Even this is not working... is it totally bricked now?
With the Monday Bankholiday, will be ages before I get my Desire back. Awww!!
If anyone has any idea how to help, appreciate it alot!

I had the same problem with mine but in my case I dropped it on the floor but the screen hadn't any visible problem and the buttons below worked fine and the notification LED told that it worked. I sent it back to HTC and they replaced the screen under warranty. Tell us if you found another solution.

[Q] Phone doesn't turn on immediately and problems come after

Hi,
My phone won't turn on when I pressed the power button, after leaving it awhile, it lights up and it shows the white screen with 'HTC' logo, then it vibrates non-stop for 5-6 minutes, then the vibration stops. After leaving it awhile, it eventually boots up to the phone (sim unlock) and can b used normally. The thing is, rebooting the phone will also repeat the problem mentioned above. Nothing for some time then white screen comes out with non-stop vibration. Even if i boot to recovery, it will still be the same.
Any ideas to fix this?
Thx in advance:fingers-crossed:
Sounds like a hardware problem...clear cache and whatever in recovery....maybe dalvic cache isnt sticking after reboot(if your rooted) but other than that not sure

[Q] Display and touch screen major issues following lollipop update.

Problems with my Samsung Galaxy Tab S 8.4 SM-T705:
1st: October 2014
2 weeks after buying, my tablet's battery drained overnight from 45% to zero. Next morning, I turned my tab on after charging to find out that the Tab starts but without any Samsung GAlaxy Tab S logo or Samsung Logo and the Screen has turned green, rendering it difficult to read in auto brightness mode or low brightness mode.
I restarted the device 2-3times and the device started working normally. This was my 1st device restart. I never used to power off the device before.
In 1st 6months, this greenish display problem n logo problem occured 2-3times, and i ignored it, because, it used to get resolved by itself with restart and I had no service centre in and around 50km to my work place.
2nd: January 2014
My device all of a sudden stopped working.. actually hanged.. I managed to turn it off but failed to restart it.
Later I realised that the device has restarted, but the screen was not responding when the screen blinked for a moment with the opening of book cover.. and the back cover of device was warm..
Googling taught me the way to access recovery screen n I opened recovery mode with "power+vol down+home key" and pressing vol down in recovery screen to restart tab.. again the tab started working fine..
3rd: Lollipop update: May 2015
I did Lollipop update. The device was smooth to operate at first. But gradually, i noticed that unlocking the tab failed to light up the display everytime, just the soft keys lighted up. But one day, the device freezed with no response from touch screen. I was unable to switch off the device also.. I had to drain the battery by playing music using S voice to turn the device off. "power+vol down+home key" too was not working.
On googling, I learned to reset device with "power+vol up+vol down" keys pressed together. finally the device restarted, but the device used to hang occassionally.
Googling let me know that i need to factory reset device upon firmware update for normal functioning, which i didn't do after update. so, I backed up my device, uninstalled many apps to make the device run a bit smooth and did a factory reset.. Resetting didn't improve the situation much, but now, the device display failed to light up on a regular basis on unlocking most of the time..
Now the situation is that, the device turns on, finger print scanner works, all apps n everything working, but display remains black, and touch screen is not responding.. using sidesync, everything on Tab can be accessed via laptop.
Tricks tried:
1) Factory reset
2) power+ vol up+vol down
3) power+ vol up+home key
4) power+ vol down + home key
5) Power off using sidesync and then restart
Results: All failure. Everything works but the display never lights up normally..
Plzz help....:crying::crying:
Bump. I'm starting to have similar problems with my SM-T800 running 5.0.2. I open the cover and the device fails to turn on. I press the power button and the screen stays black but the notification bar turns on. I can shake the crap out of the device and the screen stays black but I can see the notification bar flicker. Driving me batty.
If i had any problems like you guys, I would just return it to the place i bought it, for a refund or replacement or even a repair, post it to the service centre if it`s too far to travel too.
You problems sound like battery and or loose connector inside your tablet, it happens frequently on Samsung tablet for the connectors to come loose, if the tablet is dropped or twisted, no outside damage might be seen.

Xperia Z2, flashed long time ago, screen all black out but still responsive

It was 2 days ago since my phone screen suddenly black out, still responsive thought, checked by entering the passcode, answers call, and turn on the flashlight. If i pressed the power button which means screen on, the screen showing a very low white light over all the place. And when i pressed the power button again which means screen should go off, it's off like a normal. I tried search for solutions mostly suggests to sony companion software repair that brings to factory reset. But sadly i can't use it because my it says i'm using modified software. I'm planning to flash my phone again. Currently, usb debugging is off and can't turn it on since the screen black.
Any suggestions for what should i do? Maybe cast the screen to pc using some apps?
