I had been watching a film for about an hour through my Sony HT SF1000 Home Theatre System then all of a sudden the sound cut out then 5 or 10 seconds later the receiver turned itself off. I tried turning it on again this time I noticed the receiver was displaying 'protection' then it turned itself off again. This is what it does now, I turn it on, the word protection comes up and 5 to 10 seconds later it turns itself off. I've checked the speaker connections they seem OK and I have gone so far as disconnecting them all from the receiver but I still get the same problem. Can anyone please help me.

This is a failure of the power supply or the amp. In either case, this unit is one that the boards are available and should be replaced. The first thing you must determain is which board is bad.
I have been repairing these since they started making them, and can tell you that it is not an easy task to figure out which board is bad. You will need a multimeter, and then know how to use it very well.
Sometimes you can get pointed in the right direction just by knowing what was happening when it went bad.
If the unit was working and you turned it off, then the next time you went to turn it on you started getting the "protect" message in the display, you most likely have a bad power supply board.
If you were listening to the system and it just shut off on you and then when you turned it back on you got the "protect" message, then it is most likely the amplifier board.
There is one more thing to check before you ever buy a board for this unit. If the fan in the back is not turning when you turn the unit on, it may only need a new fan. Lets hope that this is your problem, it is cheap and easy to fix. The other options may be better for you to take it to a service center to properly troubleshoot The boards are a little expensive, but that is what Samsung does with these units, they replace the boards. Most all other audio equipment from all other brands do not even make the boards available.
Check the fan first, if you need the part number let me know, I think I may have a manual to look it up for you. If you want to try and check the boards, I may be able to help a little more, but this is a very difficult thing to do over the internet.
I would appreciate it if you would wait until we are finsihed communicating on this problem before you rate it.
Thanks,
Dave

Check the settings sometimes there is a setting to mute output volume by 10db, 20db, etc.
