So glad I found this forum . I have a HT-J4500 and mine started with this problem on Wednesday ( 17th) Was watching a dvd, paused it and because i took a while to come back to it, it had automatically turned itself off, and whwn I switched t back on it started with the reboot cycle. None of the other functions work either. ( Bluetooth, D/In Radio and AUX). Samsung customer service wasn't much help as they said to take it to a repair plaace which for me is nearlly 40 miles away. Inawait their rsponse with this.
