Power plug in the home theatre system the hello banner comes on,then it says protection, then its says goodbye.the red power suts off for about 5 seconds then comes back on.The unit is only 18 months old. any suggestions

Unplug speakers, try again,

That's the power supply board isn't it. Have you checked the main power amp board? For when the power board failed it might have taken out the main power amp with it!

the sudden power cut-off can either blow the fuse or corrupt the system of DVDs.but, some DVDs has protection for this occurrence.try not to use it for sometime.then if it's well rested try turning it on see if is resets it's protection circuit.if not, a new unit or call a technician for it.

Uhmmm. . .okay. . .I would use nothing less than 16AWG speaker cable. Do not run the speaker cable parallel in close proximity to any AC wiring. Speaker cable rated to run through walls with usually be color coded red and black. Connected the red to the red on the speaker and red on your home theatre receiver. Do the same for the black. If speaker cable insulation is clear, look closely for subtle markings or writing on the insulation. The writing will only be on one of the two wires. Designate that as the POS or PLUS or + or RED. Connected it to the red on the speaker and the red on the back of your home theatre receiver. The other is by default the black and connect it to like colors. Repeat for all 5, or 7 speakers in your theatre. Your subwoofer probably has a seperate amplifier, so it gets it's power from it's own AC power plug. . .so plug it in. The sound coming from the Home Theatre receiver will be low-power and will carry on an RCA cable. Look for the subwoofer output on the home theatre and connect it to the input on the subwoofer. There may be a right and a left input on the woofer. . .it doesn't matter which you plug it into. . .either one will do.

You probably have too much power running to your power strip that you probably have your xbox, playstation, tv and home theatre system plugged into, try using seperate wall outlets for your tv and home theatre system

I have the same problem.
I did my research and this is the solution:

Your HT system is overheated and the fan is not working. Just replace the fan and you will be good to go.

Your ICs audio amplifiers are in short circuit thats why that legend are coming for protect your theatre of more damage you got to replace the ICs.Good luck

1. With the home theater system off, press and hold the REMAIN button on the home theater's remote control for 5 seconds.
   Note: You can release the REMAIN button when the POWER LED blinks blue/Red depending on model.
   
2. With the SWA-3000 turned on, use a ball point pen to press the RESET button on the back of the SWA-3000. The POWER LED in the front of the home theater blinks two times.
