DVD and TV Connection Problem

Just connected our Panasonic DVD (DVD-RV31) to our new Panasonic TH-42PZ77U plasma flat screen. All is well except the DVD-TV connection. Whenever I power up the DVD player, it does operate, but no picture at all shows on the TV screen, as if there is no connection at all. I have used Digital Component cables, HDTV Compatible (Monster THX Certified) for input Video; have used Rocketish Digital Coaxial cable connections for input Audio. I established all connections using manufacturer instructions and obvious color coding methods. Why is there still no connection? Does the older DVD player require different cables or different connection formats? What's up!?

SOURCE: Component Video inputs do not work

I started back in the day of tubes. A family would have one set and it would be a 19" black and white. There are different resolutions now. The components probably do work, but, they don't pass the 480i signal. The satelite converter's analog signal needs to be set to 480p and the DVD needs to be set to progressive if it does have that setting. If the DVD is not a progressive scan DVD, then, the only inputs that it will show on is the analog signal. Some of the dish converters have a switch on the face for changing the resolution. If yours doesn't then put it in an analog source and go to the menu and change it there. Then move it to the component input. Hope this helps.

SOURCE: lose audio to receiver when connecting component video input

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.

SOURCE: connecting VCR to TV

Oh man dont shoot your stuff instead use your remote and go to your menu and select your input. You tv is looking at your coaxial input but you can select which input you want. 1, 2 front back whatever you need. channell 3 or 4 has nothing to do with connecting up your dvd if you connect and choose the front connection in your menu.

SOURCE: connecting to front inputs of a Toshiba tv

As a replacement for "Dolby Digital DT3 AV cable" can be used a " 3.5mm (mono) to RCA(or coaxal)" Cable.
Just make sure that DVD Player set for "SPDIF/RAW" or "SPDIF/PCM" output

SOURCE: 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.
  5. further instructions continued in my next comment post please read.

No viedo from dvd on tv screen, only audio


What type of connection are you using when connecting the DVD to the TV? (Component, Svideo, etc) You might want to first try a different connection from the DVD to the TV. Let me know if that works. Could be a bad cable also or a bad connection.
