Screen going bad?

Was wondering if my screen is going bad and needs to be replaced. I sometimes get black lines on the screen when I press the button to turn the screen on. Doesn't do it all the time but probably 1 out of 10 times when I press the button. Works fine when screen is lit and don't see any black lines. Only happens when screen is first activated to turn on.

Thanks,
Teresa

Noting to worry about untill you start seeing black lines all the time, then I would say you might have to replace the screen or the mainboard if your screen is fine.

The LCD is failing and it has either been impacted with something or the edges are leaking. When you press on it you are making a bad connection better. Replace it.

Turns on then freezes


You may have to do a hard reset on your phone if you haven't already. This will erase everything that has been placed on your device since you have had it--contacts, pictures, videos, texts, emails, etc. It is important that all of your information is backed up to the computer by Hotsyncing your device. If you have not Hotsynced your device recently then you will lose all your information, but since it only goes to the Logo you may have already lost your information. I have a Treo and that happened to my device.

To do a hard reset:

  • Press and hold the on/off button while taking the battery out of the phone (DO NOT let go of the On/Off button while taking the battery out and do not release even after the battery is out).
  • Count to ten and then while still holding the on/off button put the battery back in (DO NOT let go of the On/Off button)
  • The phone should power up and show the Palm logo and at the bottom of the screen the black bar should keep getting longer until it reaches the other side of the screen. The screen should change and say "Access Powered" and then go back to the Palm Logo and that black bar at the bottom of the screen should get longer again.
  • If the phone doesnt show "Access Powered" and stays on the Palm Logo screen, then make sure that the black bar is as long as it can be and then release your finger from the on/off button.
  • There should be another screen that comes up and asks "Reset Phone?"
  • At that point you press the UP navigation key to say YES or the DOWN navigation key to say NO. Either one you press, will restart the phone and it should load fine thereafter.
Sometimes the on/off button gets stuck so you might have to play with it a little. If that the button still doesnt work, you need to take it in to a SprintNextel Service Center and speak with a technician who will open the device and test for any physical or liquid damage which could be causing the button to be inoperable.

T-mobile dash


youll have to reset it. with the phone turned off, press the two soft keys and hold them down. soft keys are the buttons with the lines on them located below the screen. as youre holding down the soft keys, you need to press the power button. it will start to power up then go to a black screen with white writing. press the send key. the phone will reboot.

careful, because this reset will delete all personal data and set everything to manufacturer default....good luck!

means your firmware is corrupt. the only way to get you back in your device is to do a hart reset via your sw keys.....

WARNING, This will delete everything that is stored on your device, and unless your computer can recognize your device, you wont be able to get it back.

in order to the the software reset, the device needs to be fully off. preferably, take the battery out of the phone before you get started.

press and hold the 'soft keys' (buttons above the back arrow and home keys, they have a line on them) and hold those down. while you are doing that, press and hold your power button for about 3 (three) seconds and release the power button. the phone should begin to turn on but then it should go to a black DAS screen with white writing. at this time you can release the Soft keys.

press the green call button to reset the device. it will reboot and you should be able to get in your phone. if this fails and if the computer does not recognize the device, you will have to contact either your phone provider or HTC to replace the device.

Button stuck?


or course, powercycle....if that doesnt work, a master reset will be needed.....because it sounds like there might be somehitng stuck on the screen in the corner for make it scroll around, clean the screen with a qtip and rubbing alchohol.....if that doesnt work, try a software reset. with the phone off, you will have to press and hold the button withthe lines on them and press the power button.....release the powerbutton.....the phoen should turn on and go to a black screen with white writing....release the soft keys here and press the green call button...it will reset the phone, but in turn, you will loose your info that is not stored on the sim or media card...

this is hard to do, so if you can navigate through the phone go to start, setttings, system, clear storage. it does the same thing. good luck :)

UNCOMPLETED MDA UPDATE


this is a sw boot up screen. this is what the screen will look like with no sw on the device, so you guessed it....the download was unsuccessful and corrupted the firmware.....if you tried to reinstall the sw again, and it does not work, you might need a new phone....contact t-mobile to do that.....OR, you can try to do a master reset by pressing the sw keys.

to do that, turn off the phone, and press and hold the soft keys (buttons located beneath the touch screen that have the lines on them on top of the green call button and the red end call button).....while holding these down, press the power button for 3 seconds and release the power button.....all this time you are holding those soft keys down....the phone SHOULD turn on and go to a black screen with white writing.....at this time you can relase the two buttons......press the green button and reset. if this does not work.....my friend, you need another one......good luck!
