The system shuts off after a few minutes

You have a few options depending on the entire system.

Do you have the TV audio output connected to the home theater system? In that case, connect the Blu-ray player to an HDMI input on the TV. Then leave the home theater system set to the TV input, while the TV is set to the HDMI input for the Blu-ray player. This is the simplest method.

You could use an audio extractor/converter. Here's an example: https://www.amazon.com/J-Tech-Digital-Premium-Extractor-Converter/dp/B00BIQER0E . This will let you send the video signal to the TV (with a second HDMI cable) and have digital or analog audio sent to the home theater system.

If the TV doesn't have an available HDMI port and the home theater system only has analog audio inputs, you could use an HDMI to component video converter. You'd use something like this: https://www.bhphotovideo.com/c/product/770115-REG/KanexPro_HDRGBRL_HDMI_to_Component_Converter.html . (Do not use an HDMI to component cable. Those only work with some projectors.)

I hope this helps. Please add a comment with more details about your TV and audio system for more specific information.

Don't know what service provider you have, free to air, satellite, cable or what? Try feeding the TV another signal and see what it does. Play recorder movie from DVD, or if you have a VCR around even try that. If it plays the DVD etc, with no issues, then TV is not the problem, most likely the cable box, satellite box etc, could be as simple as a bad cable connection at the house, a splitter or street box. Eliminate all the simple things first, then look at the TV.

Sounds like a power issue, do you have it all hooked up to a surge protector?

the easiest way to get signal to your HT-Z320 is to run the audio cables from your cable or sat box to the input on your theater system...for the dvd either run HDMI to the LED TV or component (whatever it supports) the Wii system can be plugged into any AV -IN on the LED tv (if you want to use the Wii on the theater system you will need to extend your RED AND WHITE audio signal cables to the input on your theater system.

Hope this helps.

unhook and reconnect a few times, try with power on and off, (they have to communicate with each other) if not, return receiver and get a new one.. I had this happen with my yamaha...

For connections of audio, so that you can hear all tv audio through the
surround system, connect either an optical audio cable or red & white
analog audio cables from the tv to the home theater. If you are using
optical audio, there is a plug on back of tv labeled for digital audio
output and an input on the surround sound system. If you plan on using
analog red and white, use the PROG OUT red and white output jacks on the
back of the tv to the AUX input on the home theater.

For video connections, to get HD you will need to be using either HDMI or
Component cables. HDMI is the cable that will provided 1080p signal (the
best HD signal), but if the source does not output 1080p, then your tv
will not display 1080p. Most cable boxes output at 1080i or 720p when on
HD stations. This signal still provides great picture quality, but HDMI is
not needed to get these HD signals. You can use component cables for your
cable box and the DVD player output to the tv for video. HDMI might give
you a slightly better picture quality but the signal will be the same.

To make the connection, you will want to connect from the cable box to the
tv (component or hdmi). Also from the home theater system to the tv using
hdmi or the video cables from component (red, blue, & green cables).

We hope this information is helpful to you.

Sounds like you have a loose cable. Check that the connection is really in well. If the problem continues I would get a new set of cables, especially if you are using the ones that came with the receiver or dvd player.

The video is switched by a single chip similar to the one that switches the audio signals. It is possible that the chip is defective. Even as a shotgun approach, changing the chip shouldn't be more than $15-$25 for the part.
Keep us posted.

Unplug the Bose Media Center from the wall. Leave unplugged for approximately 30 minutes. Then plug the unit back in. Allow a few minutes for the Media center to initialize. Your sound should return as normal.

Most systems like this have what is commonly called 'protect' mode. This usually kicks in when the volume is at a very high level, and the unit tries to use more power than its designed for, or it is overheating. The reason why only this connection has problems and others do not could be a few reasons. One, satellite signals usually carry high quality digital sound, and use more power to play sounds that may be inaudible. Two, You may also want to upgrade your composite cables to the highest possible quality. (There are many durable gold plated models that work well). Low quality cables could hasten your problem and produce signal bleed. In addition to this, the unit may cut power when it overheats. Make sure the vents on the unit are not obstructed, and that it is not near other components that are generating heat.
