Re: Powers off by itself and says "problem"

I opened my theater system; the same as above and in front of the fan i found a ball of aluminum foil burned up. i took it off and the problem has not happened yet. before, it only took 5 minutes to shut off, it has been 2 hours and is still on. i hope that this works for you. good luck.

Re: Powers off by itself and says "problem"

It can go for hours without interuption, and one ime i noticed that the display said "check fan" and then protection and goodbye. I decided to take look and opened it up. The fan is covered by an aluminum shroud, after i removed the shroud i noticed that one of the sound filtering caps were blown. I couldnt find the ratings on the cap, but am researching.

Re: Powers off by itself and says "problem"

This message is supposed to indicate that you have wires crossed at some point. Maybe the speaker wires are touching? I have a similar issue, however my receiver does not say Protection - it just says Goodbye. Samsung support says that this is an issue with the box and likely needs to be replaced.

Check all of your speaker wires, and call the Samsung support 800 number. They are pretty good.

I was playing music and it just stopped playing. no sound came out. Checked all of the wires and they were fine. I think I blew the amp because no sound comes out with dvds or anything. I just don't know...

Did the receiver shut off, or did it remain powered up?
If the unit overheats, it will shut down. They can also shut down if the volume is maxed out. Most times when this occurs you can power down and wait 5 minutes to power it back up.

What source was being used at the time it stopped transmitting sound?
Have you tried to change sources?

I have an audio receiver that powers up and the shuts down. I've replaced the power cord (due to rabbit) and the fuse. But continues to shut down??

Why did you replace the fuse - did it burn out or opened? It's probably shutting down because it's detecting an overload. Inspect the circuit board for any shorts. I recommend having a repair shop isolating the problem. If it does blow fuses, then there is definitely a shorted transistor on the final amplifier output stage. Otherwise, if a fuse is shorted you don't need to replace it because it's suppose to be shorted.

I have a samsung ht-tx75 and it keeps shutting down every 10 minutes saying protection.the fan is working

Protection is very likely caused by an over heat condition, even with the fan working if the receiver is in a very enclosed place that warms up and is not ventilated it will cause the problem. The solution is to provide more ventilation so that the receiver can cool itself properly.

My system shot down during a movie

The reason why your receiver is going in protect is because there is a short circuit happening. This would either be on your speaker wires, speakers or receiver itself. What you want to do to check would be:
1. Unhook all sources and speakers from your receiver.
2. Turn on your receiver and crank up the volume to maximum, if your receiver does not shutdown or go on protect then the receiver is OK. If it does shutdown and go on protect then its an internal problem on the receiver and you would need to send that over to an authorized service center.
3. Hook up a source and 1 speaker. Play something from the source or the fm tuner, Crank Up the volume to about 46 or 47 volume. If the receiver does not shutdown, its good.
4. Hook up a second speaker and repeat the process until you encounter the pop and shut down
if for example you encounter the pop on the 4th speaker, try changing the speaker wires.
5. If the receiver still shuts down then it would be a short on the speaker itself and it would need to go to an authorized service center.

I belive that you have a lot of dust how is gatherd behind the system in the amplifier and it is preventing it to cool down you need to blow it clean and make sure that you keep the system gets cool air

if the temp in the amplifier gets to high it shut down the system instand of burning it very clever solution from the manufacturer

you have a very good system good luck

Center speaker channel

This sounds like a bad connection inside the receiver. A 5 minute fix with a soldering iron and about 30 minutes to get to it.
If you can solder you should be able to fix this yourself.

RCA RT2250 consistant shutting off in Satalite mode.

Mine will always just turn off every minute or so after a hard shut down(ex: power outtage). I have to turn it back on and then hold the set button for a few seconds, then it stays on, until i turn it off manually, since the remote won't turn it off.
