Intermittent, random, loud popping noises.

With just the speakers hooked up to receiver, no antennas or input devices, volume set at minimum, system makes loud popping noises. Also, whenever I press any control button on the front it makes a loud clicking sound through the speakers a minimum volume.

Check the impedance (resistance) on all the speakers and the speaker wires themselves.
Power up the unit with no speakers or inputs attached at minimum volume and see if it still goes into protection mode.
Most speakers should measure between 4 and 8 ohms for most systems when disconnected from the receiver.
If the unit says PROT even with no inputs at minimum volume with the speakers detached, then there's a problem with the amplifier itself, probably in the output section.

My Receiver is emmitting a loud high pitch hissing and cracking noise when volume is raised in Video 1 and Video 2. It is not the speakers as they all work and have the same noise coming out of...

This happens only in Video 1 or Video 2 using analog audio? Try using an HDMI cable or the digital input(optical or coaxial) cable and see if this issue is heard though these connections as well.

Hearing my television through my home theater system

Without knowing anything about your TV receiver all I can assume is that the TV has a least an RCA analog audio OUT. Run that to any available analog input on the HTS. make sure the TV's audio controls (hidden in a menu somewhere) is set to Fixed so the TV volume won't affect the HTS volume. Then you can turn the TV speakers off and still listen through the HTS.

You'll only get stereo this way. Ideally, you would have a digital audio source for the TV audio signal.

Tuner Keeps Turning Off when a Loud Noise is Played

It's a receiver, not a tuner.

Clearly something is overloading it or forcing it into self protection.

What else is drawing power from the same souce as the receiver, or from its convenience outlet. There IS a limit to how much current it will support.

Try checking the speaker connections and their impedance to make sure it's not unacceptably low.

Speaker pop

Volume is up to high to begin with or there could be some power source close to the unit that is causing it. Turn down or turn off volume and try to do it. Thsi isn't a broken system it does happen to some units, mine included butr when I do the things I have listed it is much better. It is worse with my better sound systems.

On my Sony Surround Sound tuner, if I raise the volume up to a certain level (not that loud), I get a flashing sign ''protect'' and the sound to the speakers are cut.

Sony has protection in these receivers for two main reasons.

1 - Checking for DC voltages on the outputs to speakers. Not your particular problem.

2 - Excessive current being drawn from receiver on one or more of the speakers.

Number 2 should be your starting point in finding a solution. Put the volume level on Medium - 35 to 40 on the front panel. Now listen to all you speakers in turn. Any scratching noise will indicate a defective speaker. Remove this speaker from the receiver output and check again if the set goes into protection on high volume.

If you could not find any strange noises on the speakers, remove them one by one and test the set on high volume.

Never - attempt to disengage the protection on this amplifier. The only times we have found the amplifier to be defective with this protection error, it has done so no matter the volume level. Therefore I believe your problem to be a speaker or speakers.

Good luck!

Audio Issue

You may have tried this, but when you hook up audio out from TV to audio in on reciever, did you try the different input options for the reciever. Often times, audio in is an aux1 or aux2 setting on the receiver. If it is working with the DVD player, it is functional, you just have to get the wires hooked up and get the reciever on the correct setting. Also, even if you have TV audio out correctly configured to audio in AND on the correct input setting, the TV volume will have to be UP as well as the receiver volume. NOT ALL THE WAY UP (you'll blow your speakers), but up about 25% for you to hear it.

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.

Try to increase the speaker levels through setup. I had the same problem and I increased the speaker level from 0dB to +10dB, and seems like it is better now. Let me know how you make out.
