The hdmi input # 1 and # 3 do not work, only input # 2 and # 4 work. why?

OK, If its the Samsung Sound Bar, this item should have 2 HDMI input, 1 3.5mm audio jack input and a digital audio input (fiber optic). Since there are various input, the remote control should have a source button, or it will probably read O/A Input, this is to change thru the inputs from the sound bar. If you connected your TV HDMI output to HDMI 1 from the Sound Bar, then press the source button to reach HDMI 1, maybe it will be display with a different name, like sound 1, or DIGI.1 Give it a shot and let me know in the comment section. Good luck.

If you see a no signal message, then it means that the signal output format of the PS3 does not match . It happens if you have previous used it on another tv and now connected it to a different tv. To resolve this, turn off the PS3 . Press and hold the power button on the PS3 till you hear three BEEPS. The PS3 should automatically detect the tv's resolution and the initial setup screen should appear. After that you should just follow on-screen instructions to set it up.

hi,
You have to check the digital audio assignment of you AVR for HDMI 1 and HDMI 2. There is three options for the digital audio for HDMI 1 and HDMI 2. You can set it as optical ,coaxil, or the HDMI itself. In you receiver the assignment may be in optical input or in coaxial input for the two HDMI inputs.

1. Go to the system setup
2. Select input setup
3.Select input assignment.
4. Select all the three input ,you are using as HDMI

This receiver has only one HDMI output, but 4 HDMI inputs. If some inputs don't work, try connecting the equipment (DVD for example) to HDMI input which works with other equipment....
For the RCA (composite) video input - it won't work, because this receiver don't have any video processing circuit.
So HDMI input video goes to HDMI outout connector.
Composite (RCA) video input goes to Composite outout and no other video output.
S-video input goes only to s-video output.

Okey,

Connect the hdmi, into the HDMI 1. that is automatically input one. Connect the 2nd device on Input 2, thats next to input 1 and hdmi, leave the input 1 empty, as the hdmi is connected to that.

3rd device into input 3
4th device into input 4.
