Coby dvd938 can not change to aux input

Go to any store with a comprehensive A/V Dept. and tell them you need a coaxial input/analog output adapter with Toslink...they run about $13-$14 dollars

You're Going to have continuous problems like that with your current configuration. You should plug your video and audio cables directly to a separate input into the back of you set. That's provided of course that you have another input on the set. If your set and dvd player are HDMI cable capable then you also would have typically another hdmi input. In that cast you don't need separate audio cables. The audio is carried as a digital signal in the HDMI cable.

The DVD938 only has analog audio input (2.1 channel), thats why you have only a white (left channel) and red (right channel) audio connection from your ps3 to the home theatre. There is an option called PROLOGIC in the setup menu that will simulate 5.1 with the 2.1, it basically takes the 2.1 channels and splits it into all the speakers.

Your TV would have to have an AUDIO OUTPUT port (RED/WHITE) and that would go from the back of your TV, to the RED/WHITE input on the DVD938. All your other devices would go directly to your TV. After you do that, you change the input on the DVD938 remote to AUX.

Make sure the video connections are in the correct ports If they are, get to the screen with the coby logo, make sure no disk is in the tray and reset the DVD player with remote:

Make sure you do not have a disk in the tray. Using the DVD player remote control:

1. Press 'Setup'
   

2. Press the right arrow 4 times
   

3. Press the down arrow 7 times
   

4. Press Enter
   

you can download the manual here: http://www.retrevo.com/support/Coby-DVD-938-Home-Theater-Systems-manual/id/23481ag406/t/2/

Take the red, yellow and white cord and plug it into the back of your cable box and then run it to you tv and then push the Source button on your remote on the Coby until the display says "Line" and there you have it

Take whatever audio connector your cable box has for audio out and run it to the Coby directly.

Specify: What TV?

As input or TV as output?

Former: generally, no
Latter: depends on what speaker systems the TV has.
