Inputs not working on Hitachi 55VS69A

Under Audio or Audio Settings on the on-screen menu, TV Speakers is set to On. All of the cables physically connected to the TV and the input devices are secure. Switch to a different input device and verify there is sound from the TV speakers (for example, a DVD player or a gaming console).

Page 18 of the manual, you shouldn't need to do steps 2 or 3.

CONNECTING A COMPONENT SOURCE WITH HDMI or DVI CAPABILITY TO INPUT 1 or INPUT 2
1.Connect the HDMI or DVI to HDMI connection cable from the output of the HDTV set top box or DVD player to the HDMI input as shown on the AVC Center below.
2.With DVI output, connect the cable from the AUDIO OUT R of the HDTV set top box or DVD player to the INPUT (AUDIO/R) jack.
3.With DVI output, connect the cable from the AUDIO OUT L of the HDTV set top box or DVD player to the INPUT (AUDIO/L) jack.
4.Press the INPUTS button, then select INPUTS 1 or 2 to view the program from the HDTV set top box or DVD player. The VIDEO OSD label disappears automatically after approximately four seconds.
5.Select ANT A or B from the INPUTS menu to return to the previous channel.
NOTES:1. Completely insert the connection cord plugs when connecting to rear panel jacks. The picture and sound that is played back will be abnormal if the connection is loose.
2. The HDMI input on INPUT 1 or 2 contains the copy protection system called High-bandwidth Digital Content Protection (HDCP). HDCP is a cryptographic system that encrypts video signals when using HDMI connections to prevent ******* copying of video contents.
3.HDMI is not a "NETWORK" technology. It establishes a one-way point-to-point connection for delivery of uncompressed video to a display.
4.The connected digital output device controls the HDMI interface so proper set-up of device user settings determines final video appearance.

Connect yellow video output on DVD player to yellow video input on TV using RCA cable. Connect white audio output on DVD player to white audio input on TV next to yellow. Connect red audio output on DVD (next to white) to red audio input on TV using RCA cable. Select on the TV using remote, the proper input for DVD player connection.

alright. make sure that your red, green and blue are all plugged in properly and that your audio plugs are also in there correct plugs. i think audio is red and yellow. correct me if im mistaken

The monitor only headrest does not have audio handling circuitry in it. the wire harness for that side is the one with the red and black wire, and the two video inputs, not the harness with the red and black wire and the three RCA jacks. It will function on the wrong harness, but it is not the correct one.

The DVD headrest has two harnesses. One of them is for power and output, the other is for input only from another source. The harness with the red and black wire has the three RCA outputs... the video lead goes to the other headrest, and the audio can be fed to an aux input on a stereo or amplifier. The input harness is designed to be Video 2 input from either a gaming system (a Game Cube is a nice option), or another DVD or video source (hand held video device such as iPod or Smart Phone like a HTC Touch Pro 2).

To get sound out of the stereo, either run the audio output from the headrest to the aux input on your stereo, or cycle the FM transmit options using the FMTX button on the DVD player unit to a station you can tune to on your car's FM radio.

If you can watch TV normally then it should be a button on your VCR remote. It could be "Input", "Line" or "Aux". Tvs with more than one input line will may require 2 presses on that button, one for each line. This is the best answer that I can give not seeing your remote. Any questions?

Yes, and it is highly recommended to do so. Hitachi’s DVD-Camcorder has an advanced analogto-digital conversion system. By using the analog Audio/Video input on the camcorder, the tape based information is converted into digital data and is then recorded onto the DVD disc. See manual instructions for switching input from Camera to Line-In.
