Hi,
There is one more update. In the last week I was trying to connect my phone to PC with SE software which come with Phone. Software recognises the phone correctly and after few minutes (while connected) I can see my phone startup screen - It ask for two options "Start Phone" and "PC MODE". If select Start Phone option then screen slowly goes to White.
If put phone card it rings as well. But not able to accept the call as screen is in full white.
