I have an Samsung HTDB - 500 Home theater system. Since recently, I am unable to run auto sound calibration and the sound logo does not play at all. I feel that there is some software corruption causing these issues.

Can anybody kindly advise me as to how I can restore these functions? Is there anyway of restoring the operating system and software? Apart from these HT system is functioning normally.

Thanking in advance for any help extended.
