Blue screen on main display

You most likely need a new ribbon cable, which is the cable that connects the two halves of the phone. They are not expensive and can be ordered on eBay, and they come with the tools required to disassemble the phone and replace the cable.

try to replace flex,,, if no luck replace also crystal ic beside the connector....

you need to change your lcd or if you want to try to fix it yourself just open your phone take it apart and then tighten up the connections to your lcd to the main board of your phone...

i have repaired this problem time after time you need to replace the flexcable which is located inside the phone between the top and bottom of the phone the problem is that these phones are very poorly made and the cable inside gets crunched up with opening and shuting of the phone its very easy to replace and change and with ebay you can find the cable for around 4 pounds inc postage if you need help opening the phone please email [email protected] i have had around 10 of these phones to fix and only 1 out of the 10 the screen needed replacing change the cable first its cheapest option! hope this helps all!

take the phone to a mobile service center and have the LCD replaced on the phone.

The problem is in connector. You need to change that.
