Hey Gamer1827,

While I personally can't provide you with any model-specific home theater system recommendations, there are a couple of common ways that you can generally configure your home theater.

Connecting several devices directly to the HTIB system may typically allow you to minimize the number of remote controls necessary, as long as the HTIB system supports the use of a universal remote. Should you not necessarily care if you have to change back-and-forth between two remotes however, you may have a wider variety of possible configurations available.

In order to use only HDMI cable connections to set up your home theater, you most likely would need an HTIB system with three HDMI ports: one for your TV, one for your PS3 and one for your cable box. Each device would require a separate HDMI cable running between it and the receiver. This option (in theory) would allow you to use one universal remote to control each device, assuming that they are all compatible with the same remote.

Another common configuration you might wish to try requires you to connect your cable box and PS3 directly to your TV. By doing so however, you might limit yourself to using an optical digital audio cable to make the connection between your TV and many HTIB systems. In this configuration, the cable box and PS3 would again have their own separate HDMI cables, while the optical digital audio cable would need to be run from the Digital Audio-Out port on the back of your TV to the Digital Audio-In port on the receiver. This option essentially treats the HTIB system as an expansion device, instead of the center of your home theater configuration.

Should you need any additional information or suggestions, remember that you may always speak with a sales representative at your local Best Buy™ store for further assistance.

Hope this helps you out.

Sincerely,
Aaron

Try running the optical TOSLINK cable from the TV to the receiver. If the TV doen't have a digital optical output, then try going into the menu on your cable box and setting the audio output to the digital optical out. Also check your TV menu and make sure NETCOMMAND is diabled. Some of your newer HDTV have Netcommand that allows the TV to control other devices through the HDMI cable.

This is definitely a case of digital board malfunction. Since the problem only appears after a while, the input and processing circuits are ok and the problem is being triggered by faulty logic control circuitry on the digital board. Replacing the same should resolve the problem. Would you like to do it yourself?
