It seems to be some fault with the LCD connector (the ribbon wire that connects LCD to the main board) either the wire is damaged or the connector is loose. You may download the service manual for your phone by searching on Google which would have the instructions on how to dis-assemble and reassemble the phone so that you may check the connector.

My keyboard is stuck about 3/4 up from the bottom of the screen please help


What device are you on? If it is an Apple device, close the app where your keyboard is stuck by double tapping the home button and flick/slide the screen up (while you are in there, slide all your screens up, this will make your phone run faster). Here is a screen shot of what it looks like when you double tap the home button. You should be able to slide all your screens up except your home screen.

How do i open dv7-1451nr?


Instructions

1

Shut the Pavilion dv7 down and close the screen. After unplugging all cables from the computer, turn it over and remove the battery.
2

Unscrew the six Phillips-head screws holding the large T-shaped panel to the bottom of the Pavilion dv7. Remove the panel and set it aside.
3

Remove the keyboard locking screw--marked by a keyboard-shaped icon--from the top part of the compartment exposed when you removed the T-shaped panel. Reserve the screw.
4

Remove the black Phillips-head screw from next to the wireless adapter inside the T-shaped compartment. This screw holds the Pavilion dv7 optical drive in place.
5

Pull the Pavilion dv7 optical drive gently out of its bay, and then remove the two Phillips-head screws from inside the empty drive bay. Reserve the screws.
6

Remove the Phillips-head screw next to the circular intake fan vent in the corner of the Pavilion dv7.
7

Remove the five Phillips-head screws from inside the empty battery compartment. You should now have removed 16 screws in all. Turn the Pavilion dv7 over and open the screen.
8

Insert a spudger or other flat plastic tool into the seam between the speaker grille and computer casing on the right side of the Pavilion dv7. Gently pry up to begin removing the speaker grille from the computer. As you do this, move the spudger to a new location to pry different areas until the grille is completely disconnected. Mind the ribbon cable connecting the center of the speaker grille to the logic board, and do not lift the grille any higher from the computer than the cable allows.
9

Push both sides of the speaker grille cable lock forward until the cable slides easily out of the logic board connector. Set the speaker grille aside.
10

Remove the four Phillips-head retaining screws above the top row of the Pavilion dv7 keyboard. Lift the keyboard up and forward, and place it face-down on the palm rest.
11

Unlock the Pavilion dv7 keyboard cable connector using the same method as for the speaker grille connector. Slide the cable out of the connector, remove the keyboard and set it aside.
12

Place the new Pavilion dv7 keyboard upside-down on the palm rest. Slide the keyboard into the connector, close the lock and rotate the keyboard down into the computer. Replace the four Phillips-head screws.
13

Slide the speaker grille cable into the connector and close the cable lock. Push the speaker grille into its original position above the Pavilion dv7 keyboard. Press gently on all parts of the speaker grille until it is flush with the computer casing.
14

Close the screen and turn the computer over. Replace the five screws inside the battery compartment, the screw next to the intake fan vent, the two screws inside the empty optical drive bay and the screw inside the T-shaped compartment.
15

Replace the t-shaped panel on the bottom of the Pavilion dv7 and its six screws.
16

Slide the optical drive back into its bay and replace the securing screw.

The keyboard of my phone works...the screen did come on but now it doesnt come up...when it did come up, i wasnt able to open my messages...the touch screen wasnt working. when i shut off my phone i hear...


Hello,

there is nothing wrong with your screen, the problem is from the flex that connects your screen to the phone's main board. This flex must have worn out that's why your screen is not displaying any picture.

The problem is common with flip and slide phones. The flex gets worn out as a result of constant opening and close of the flip or slide phone.

I would urge you to replace the flex and I am assuring you that your screen will display picture again. You might also be lucky to find out that the flex is not well fix, that is, it may have loosed contact.

If you cannot change the flex yourself, maybe you should take the phone to a local repairer within your vicinity, so that the flex can be fixed/replaced.

When i try to slide the keyboard out of my cliq the screen turns black everytime but if i close it and try to turn the screen on it turns on


it has a loose connection in the screen. if you have insurance you should have it replaced. It's not something fixable from any menu's or settings.

I changed the screen recently on the htc touch pro t7272 and i notice the screen is only showing sideways and wont turn pright what could be the problem is it soft ware or hardware


Could be both, could be either. Let's hope it is a software issue.

One obvious solution is... well... change it back! Then do a power-cycle. (feel free to remove the battery for a few minutes before powering on)

If it went back to being "upright" when the keyboard is closed, then it is a software issue.

You also have other "sensory"-related apps to activate to better diagnose the failure. For instance:
  • you can activate Keyboard Sliding sounds
Start--> Settings--> Personal--> Keyboard Sliding

Choose a sound (any sound), test it (make sure the phone sounds off with it), then activate it.

Then open the keyboard and close it to activate the sounds. If it sounds off, then it's a software problem.

Software problems are easier to fix:
1) backup your hard-earned data (contacts, calls, sms, mms, etc.)
2) then do a factory/hard-reset
3) Once control is given to you, restore the hard-earned data.

Soft-reset the device. Then enjoy.

The slide on the card actually allows a switch to activate on the inside of the player/recorder. If changing the position of the slide on the memory stick has no effect, look at the microswitch inside the machine next.
