Lose audio to receiver when connecting component video input

When I use my Panasonic DVR and connect to my Hitachi TV using Component Video cables, the pictue is amazing. Funny though that I lose my TV's audio to my receiver. I would connect my DVR to my receiver directly if I had more inputs on my receiver, but that is not exactly the point. When all 3 component inputs connected, no audio out. Unplug the blue, sound returns but screen now black and white. Tried a different DVD player and that one gave me sound and picture if I disconnected the blue from the TV. Tried a different component video cable, and same problem. Something goofy with the blue input on the TV. Any thoughts?

I don't know if it's firmware or hardware, however, it is NOT a problem, it is the DESIGN -- and an asinine one at that.

Essentially due to copyright issues with HD video, they CAN NOT decode the video to an analog output source. That's all fine and good, however, the audio never fell into that copyright issue. So you should be able to carry though the audio signal from those sources (since in the case of the component input, they're analog anyway). I think Hitachi is the ONLY company that just disables ALL analog outputs when it senses the video signal on the component or HDMI inputs (and you have the tv set for that input). They really should have ONLY disabled the video.

I had a half hour conversation with customer service, begging them to 1) file a complaint to fix this in the next firmware version, or 2) let me speak with an engineer to give me a hack -- obviously they didn't do that :(

The funny thing is, they WILL allow the Optical Audio output signal to carry though.

I've now been frantically searching the internet for information on how to bypass this ridiculous design 'feature'. As this TV isn't that popular, there's not much info out there on how to do so. So, I wouldn't know if I can simply try to attack the firmware code, or, if I actually have to take off the back of the TV and muck around with my soldering iron -- I'm hoping firmware.

One test shows that the control signal to SHUT OFF the entire analog outputs (audio and video) is on the 'Pb' (blue) input of the component video. If I have that one cable pulled out, I can get the Audio out to work and hear everything on my external stereo -- obviously I have a completely jibberish and unwatchable picture though. Once I plug in the 'Pb' cable, the picture comes in, obviously, but the external stereo sound cuts off.

At any rate. Just to reiterate, it's a design issue, and Hitachi seems unwilling to address the HD video copyright issues any other way. I am going to obviously send them a letter by mail telling them how their 'sledge hammer' approach to this issue is ridiculous when there is a 'scalpel' approach that is completely legally viable -- and all their competitors do it that way.

For this reason I now regret buying this TV.

Have the exact same problem, opened a case file with Hitachi.

I have a feeling it's a firmware problem -- hopefully they will make my life easy and mail me the proper cable I can connect from PC to TV, and the software to run such an upgrade (as opposed to packing this big thing up and carting it off to a service center).

I'll post my experiences.

Where to hook up white/yellow input wires from receiver to panasonic TC-P50S2. HAVE audio no video feed on tv

Usually DVD players have either composite or component video out (unless you are using HDMI connections). That means you need three or five RCA plugs connected between the devices.

The usual pattern when using a receiver would be to connect the Red/White RCA cables between the receiver and the DVD player audio out. Then connect the Yellow (composite) or Red, Green, and Blue (Pb, Pr, Y component) video cables between the TV and the DVD player. Make sure the connections match at each end; with component video, it can be easy to mix them up. Not all receivers have composite or component video outputs available to the TV. The Composite video will go to the yellow connector at Video In 1 on the TV. The Component video would go to Component In 1 or 2.

Since you don't mention the model of the receiver or how that is connected to the TV, I can't be sure why you have no video. If you have an HDMI connection between the TV and the receiver, the receiver won't convert the signal from composite/component video to HDMI.

The alternative method of connecting everything would be to connect the DVD player to the TV (both the audio and video), then use the optical digital audio connection from the TV to the receiver or to a digital to analog audio converter and then to the receiver.

Please add a comment with the rest of your A/V equipment for a more solution.

I hope this helps.

Give me properly installation of stand alone dvr with computer all window how sport the dvr send me properly anstallation of standalone dvr

Take one co-axial cable, and connect the "input" port to your cable-company's wall-port.

Look at the connectors on the back of your TV. You could have:
* coaxial input (lowest video-quality)
* S-Video input (better video-quality)
* component input - three cables for video, two cables for audio (better video-quality)
* HDMI input (highest video-quality)

Look at the connectors on the "output" side of the PVR. You could have:
* coaxial output (lowest video-quality)
* S-Video output (better video-quality)
* component output - three cables for video, two cables for audio (better video-quality)
* HDMI output (highest video-quality)

Connect the "outputs" to the "inputs", using appropriate cables.

Turn the PVR on. Turn the TV on.

Use the "source" button on the TV's remote-control to select from the various inputs
(Coax, S-Video, Component, HDMI1, HDMI2).

If your TV has 'PIP' ("Picture-In-Picture") capability, connect more than one output to a second input, so that both tuners inside your TV will receive a signal.

We recently purchased an AVR 146 receiver and have attempted to connect our DVR satellite receiver, a DVD player/recorder and our Hitachi (non HD) TV, plus a surround sound system to it. The surround sound...


This is how the connection is suppose to be, DVR "OUT", to TV "IN" using the RCA plugs, then press AV on the TV. If this is how you connected it, then maybe there is something wrong with the video wire (Yellow).

As for the DVD, you need to connect an Audio wire separately because the component Red + Green + Blue wire only stands for video. Audio is Red and White, this must be connected for you to get sound from the DVD.

To connect the Audio for your DVD player, connect Red and White wire to Audio "OUT" of your DVD player, to "AUX" in of your AVR 146 receiver, then select AUX on your receiver and sound will come out from your DVD through the receiver.

I hope this is not complicated for you. This connection is simple, all you need is to understand the basics which is OUT and IN. If you want to watch DVD on your TV, this means the DVD will be good OUT to IN of the DVD. The same goes for audio.

If you don't understand, please let me know so that I can direct you further.

Good luck.

How do I convert from HDMI-in to Component-Out? Basically, I'd like to have my cable box (Comcast DVR) coming into the receiver using HDMI but would like to output to my TV using Component instead of HDMI....

looking at the manual here that should work for Video
it looks like on the receiver you would have the DVR connected via HDMI cable to the receiver On the receiver you would select this HDMI as the input. That should automatically allow that signal to be presented to the component out on the receiver you connect the cables from component out to the TV and switch the TV to select the component input -depending on the TV model this may be labeled AV1,2,3,4, etc No sound will be transferred to the TV as component is Image ONLY whats the make and model of the TV

I Have just bought this reviever (Yamaha Rx-v365)and im just trying to work out how to best connect all my devises. I have Tivo, Lg DVD player with both yellow, red white cables and blue green red cable...

Hi, firstly some terminology:
yellow cable - video composite (worst quality)
white/red - stereo analog audio
blue/green/red - video component (second best quality after HDMI)

You are correct that RX-V365 doesn't do audio over HDMI. Moreover it also doesn't do any video processing, which means composite video input will go only to composite video output (and not to component); compoment input only to component output and HDMI input only to HDMI output.

If you have more devices of same video output (in your example the component blue/green/red), you can connect them to TV via the receiver. But if only one device of same video output, you can connect it directly to TV. There is no reason to go through your receiver for video.

For audio, you can use either the analog stereo white/red cables (rx365 has 5 such inputs) or better use digital SPDIF connection, which is slightly better quality and more importantly supports 5.1 sound. There are 2 types - coaxial (orange RCA plug, can use basic rca cable) and optical (square black connector). Receiver has 1x coax spdif input and 2x optical spdif inputs. Look at your other equipment to decide which cable to use.

For the analog audio inputs, I think you can assign it either to composite video or component video. So for DVD audio white/red plugs, you can choose if either Video composite yellow plug named DVD will be used, or component blue/green/red named DVD will be used.

Problems establishing audio output from DVD RW to TV

If you own a Digital Video Recorder, such as TiVo, or a DVR from a Cable or Satellite provider, then you know you can record to the device's hard drive to view TV shows at a later time, much like the old VCR. However, saving those TV shows becomes difficult as the Hard Drive starts to fill up. The answer to saving your shows is to record them to DVD! This can be accomplished easily by hooking up a DVD Recorder to your DVR
Here's How:
  1. 1)record a TV show on your DVR that you want to save to DVD!
  2. 2)Turn on the DVR, DVD Recorder and the TV that the DVD Recorder is connected to. In my case, I have my Samsung DVD Recorder (no hard drive) hooked up to my TV via an RCA Audio/Video cable from the rear outputs on the DVD Recorder to the rear RCA inputs on my TV. I use a seperate DVD Player for playing DVDs, but if you use your DVD Recorder as a player as well, use the best cable connections you can to connect to the TV. See the articleTypes of A/V Cables for more info.
  3. 3)Connect an S-Video or RCA video cable and composite stereo cables (red and white RCA plugs) from the DVR to the inputs on your DVD Recorder. If your TV has Component inputs, connect the Component Out from the DVD Recorder to the Component In on the TV, otherwise you can use S-Video or Composite. You will still need to use RCA audio with your video connection.
  4. 4)Change the input on your DVD Recorder to match the inputs you are using. Since I'm using the rear S-Video input, I change my input to "L1", which is the input for recording using the rear S-Video input. If I was recording using the front analog cables it would be "L2", the front Firewire input, "DV". The input select can typically be changed using the DVD Recorder remote.

Denon AVR-488 , problems routing cable box through receiver to tv

If you don't have one, the manual is available online:


1. Reset to default values. Per page 36 of manual: 1. Turn off Power. 2. Press Power while simultaneously pressing Speaker A and Speaker B. 3. Once the display starts flashing at intervals of about 1 second, release the two buttons.

2. Make sure you have AM or FM radio reception. This makes sure your speakers, amps, etc are connected and working correctly.

3. Connect DVD player to HDMI 1 in and TV to HDMI Monitor Out.
Play a known good DVD that works when you connected the DVD directly to the TV via HDMI.

Select the DVD/HDP input on the receiver and play the DVD. You should not have to perform any input assignments, etc. It should just work, as HDMI1 is the default system setting for DVD.

4. If possible, obtain a STB with HDMI out & repeat step 3 using the HDMI2 TV/CBL input. Keeping the signal path all digital (HDMI) will give you a better picture quality than forcing several analog to digital conversions (component video is analog).

4A. To use the component connection, first test by connecting the STB directly to the TV via component video/audio if possible. This tests that the component video output of the STB is working correctly.

Next, remove direct connection and connect via receiver. Connect STB to receiver as shown on page 13 in manual. Connect component video output from STB to component video input #2 (tv/cbl) on receiver. Connect the STB audio output to the corresponding tv/cbl audio inputs.

Make sure nothing is connected to the HDMI2 input or to any other TV/CBL inputs (composite video, s-video, digital coax audio).

Now select the TV/CBL input and turn on the STB. You should have both audio & video.

Need diagram to connect Motorola DVR, Panasonic DMR-E recorder, A/V Receiver, and HDTV

Your not going to be able to connect in series (not sure if thats your goal) since your limited by the type of connections you can use. Your receiver is going to have to be switched depeneding on what source you want to listen too. DVR, DVD, etc. HDMI is going to important for your TV connection. Radio Shack has cheap HDMI cables.
So... connect HDMI from DVR to HDTV this will give you sound and picture to TV. Connect DVR optical or coaxial ( RCA if you dont care about surround) to Receiver to give you DVR sound thru Receiver input.
Connect DVD to receiver via optical/coaxial/rca for DVD sound thru receiver (again RCA is not recommended for surround).
Connect Component video to HDTV(or HDMI if TV has second HDMI input) to give you video from DVD.
Connect Yellow video or S-video from DVR to DVD recorder input to allow recording from DVR. Also connect red/white audio to (same) DVD input.
That should cover it.
