Network IC Problem. We also faced the same problem here. The Signal Bar shows Full Strength for a few Seconds and immediately drops down to Zero Strength but it Displays the Operator Name.

Your display circuit is broken, even if the LCD-panel,
seems to be ok the display is damaged.
This is a very common problem in Nokia phones.
The only way to fix this is to change the display.
You need a T-6 Torx Skrewdriver to do the job.
You can find displays for fair price at :

It may due to bad display........sometimes it happen when the mobile fall down..It works properly but camera and video may face problem..
