@sarah_rver just to clarify, it turns on but after a few minutes it turns off. Any LED lights on or any sign of life when it turns off?

Neither the user nor service manuals provide any particular clues based upon what you have described. Therefore, I must start with the typical failure. Disconnect the speakers and try again. I expect that the unit will power up normally.

You can reference the service manual here: http://www.go-gddq.com/upload/2010-02/10...

The main power amp resides inside the subwoofer. Check to see if there is a protect light on the subwoofer.

If there is a light or the unit only “works” with the subwoofer disconnected, I would suspect that one of the amp chips inside the subwoofer is defective and further investigation is required. There are 2 large black amp-packs inside the subwoofer (STK413-400 and STK413-=430). One or both of these may be defective.

Try removing the speaker connections and report the results here.
