Main Display I am having Nokia 6131. Its Main Display is not working properly. Only welcome screen come & immediately it goes blank. Only Mini Display works properly.

this problem occurs probably when there is problem with display
you would probably have to replace your display (LCD screen)
not much costly

this may also occurs when your phone is attacked by virus but this has less probablity in this case

Hi. Have you tried replacing the LCD screen? You can buy one here http://www.formymobile.co.uk/proddetail.php?prod=6131lcd and see the disassembly section of the following file for fitting https://www.yousendit.com/download/Y2o4WGJEY1NxRTFMWEE9PQ

let the battery run out then try again, use another phone in the meantime.

the problem is in display...better change ur display and use it...

flex problem

i think u shud chek the belt that connect the two parts of the phone screens and keypad. and if its connected well and the phone still just like it was u shud change that damn belt cuz its very sensitive electronic stuff always watch out with the belts

This link will help you with re-assembly. I had the same snag. A GENTLE adjustment of the speaker contacts fixed the problem with sound. Use the above link to check your display connections.

Try turning the phone on with the flip screen open. Do it a couple of times if it doesn't work the first time.

Hi go to ur mobiles setting and select full fectory default its security code is 12345. thanks keep voting.

You need to chance the strip in side the mobile. or else we need to change the display.
