So what to do to repair it.. can it be..? nd can i ever use its sond sytem only.. in any form.?

The PWM amp ics are bad. If you have a dc voltage on speaker terminal thats it.

Samsung Home Theater Systems have a Dealer Lock or Tray Lock Function that prevents the disc tray from being opened.
There are four procedures for turning off the Dealer Lock function. Try one, then the other, to see which works on your system.
Unlocking Procedure 1 To turn off the Dealer Lock function, follow these steps:

1. Turn on your Home Theater System.
2. Press the Stop button on the front panel and the Power button on the remote control simultaneously for four seconds.

Note: Repeating the two steps above turns the dealer lock on again.
Unlocking Procedure 2 To turn off the Dealer Lock function, follow these steps

1. Turn on your Home Theater System.
2. Press and hold the Function button on the front panel for 3 seconds. The display shows the word Unlock.

Note: Repeating the two steps above turns the dealer lock on again.
Unlocking Procedure 3 To turn off the Dealer Lock function, follow these steps

1. Turn on your Home Theater System.
2. Press and hold the Open/Close button on the DVD player on the front panel for more than 4 seconds.

Note: Repeating the two steps above turns Dealer Lock on again.
Unlocking Procedure 4 To turn off the Dealer Lock function, follow these steps

1. Using the HTS remote press the Menu button + 712, and the HTS will display CAN OPEN.

The Dealer Lock feature is mainly used by retailers to ensure that the display discs are not removed. However, parents of young children may find this feature very useful as well.

Found this information for a Samsung unit with the same internal components experiencing the same problems. http://www.fixya.com/support/t194959-display_sound. I know this drove me nuts so hopefully it will help others.

by the way this is the second one I had that did this, it must be a ht-q80 problem
