W910i Camera, videocall camera, Radio problem

I have w910i 1 weeks ago and have test all function, work fine, but yesterday.. i wanna take a picture, camera does not open.. just say press 0 for help and sometime nothing text appear(nothing happen).. then i check 3G camera,same too..not show up my face.. and radio also got a problem like camera and 3G camera..still can't open..

is it hardware problem or what?? Original firmware is F1FA035, and nothing change until now.. i have update firmware to the latest version like R1Fa0.35, 037, R1CA309 and many version.. and the result still same.. if this is hardware problem, what is it? IC? or cable?

sory for my bad english.. hope someone can help me :a018:
