When iam sliding the phone screen become white & keys r not working

my friend your phones LCD display has gone
replace with a new one

Nokia 6600 Slide
I can hear my phone switch on however the screen does not start up correctly, only a white screen.

hi, the main reason the screen turns whits is due to the thin ribbon that sends the data from the circuit board to the screen being damaged what happens is that the thin copper wires that are inside the ribbon ware and then break causing a short to the screen and this is what turns the screen white. this happens on most flip and slide phones as the ribbon moves when you slide or flip the phone so over time it becomes brittle and you lose the connection and this turns the screen white.

sometimes it will right itself if you open and close the phone a couple of times but this wont be a long term fix how ever it may be that bad that this will no longer work, its not expensive to get this ribbon replaced but taking you phone to a small phone shop would be your cheapest option.

Maybe a magnet has come loose in the handset, Or you have exposed it to a magnet. Or there is a loose conection when you slide the handset. Either way you will need a new display

There is a fix. Ok so what you wanna do is power off your Samsung rant then you take out the battery and put it back in. After that you open to the slide pad and hold down the T and Y keys then power it on while still holding the 2 keys after the Samsung logo pops up then you can let go. Keep the slide keys open while it is powering on. You can close the slide pad when your screen shows up then it should be fixed. Well hope this works for you it worked for my moms phone when she was having this problem. Note: If your phone screen freezes or turns white again just redo the process.

THIS WORKED FOR US: Hold down the power button until you see the "CANCEL" icon; tap around the screen until the "CANCEL" button turns blue - this will take you back to the slide feature. MAKE NOTE OF WHERE THIS SPOT IS ON THE SCREEN. Repeat the "cancel-screentap" process to find a 2nd spot in another area of the screen. While on the "slide" screen, draw a line between the 2 spots; when you return again to the "slide" screen, the "slide" should work.

ONCE YOU HAVE OPENED THE PHONE do 2 things:

1. RECALIBRATE the screen
2. LENGTHEN the screen saver time-out to something other than the shortest time available.

Hope this works for you - GOOD LUCK!

PS - dunderground posted the following solution in Apr 2009:

"The fastest way is to be on the slide-lock screen & hold the side volume button in the Up position until "Press volume down key to check" comes up onscreen. This may or may not work on all firmware versions on the current i9, but works on most. Make sure to hold the button firmly in the Up position. You will first see the normal volume speaker icon show onscreen and the volume rise, but just keep holding it Up, and eventually you should see the pop-up box noted earlier. The moment you see that pop up onscreen, immediately press the side volume button in the down position. A white calibration screen should now show & you can calibrate the touch screen using the stylus."

try this type *#7370# 

The strip that connects both the upper and lower slider is damaged ... replace it

My cell w550i shows white screen no boot screen

Well the 8125 is an HTC Wizard not a TyTn. The TyTn is an 8525 and is prone to white screen problems that are discussed at length on www.XDA-Developers.com

It may be in your case that the internal connector is needing re-seated. To do this yourself is warranty voiding but if you dare there are manuals and guides here:
