Dear VICER, I am an electronic technician in Spain. I have tried to obtain the scheme. I think that the problem must be in the generation of the sign of video that is realized in the ASSY PCB-MAIN; DVD-HR720 PAL and I need to identify the component. Could You help me to obtain the scheme?. Thank you

if it is not connected to a soung system that might be at fault reset it to factory default through the settings menus available on the remote and see if that makes a difference. If it only works via a remote control ensure the remote is functioning .
If you reset successfully and thereis still no sound, (and the cause is not a sound system or such,) vthen you probably need the services of a technician. No doubt , even in todays modern tvs, the sound output can go independently of the video output.
i think your radio has power problem.
please check the radio fuse on fuse board if its good please ask for repair electronics technician to fix power problem of your radio.
it can be the failure of sound output cct or power regulater cct .
There is two causes to this fault. The first one is the absence of voltage to video output transistors. Check the input voltage, it should be around 290VDC, that supplies the collector terminal to each video output transistors. The second reason is failure of color matrix section circuit. This circuit is within the Chroma IC. If this is the case, the IC should be replaced. If you're not familier with electronics, it is best to contact any service technician.
Using your stereo system for audio portions of video programs - such as DVD, VHS tape, etc, - is a great way to upgrade sound quality. Many people are in the same "boat" as you; trying to get the TV audio out of the TV and into the stereo.
You'll need to located an unused left and right audio input of your stereo. These new jacks may be assigned to "Tape" or something else - but for you, it will now be "TV". You'll also have to locate the left and right audio output for the TV. This may be located on the back of a cable TV box, satellite converted, Tivo, etc. if you such a device to receive TV signals. Simply follow the cable from the rear of these devices to the rear or side of the TV and disconnect. Reconnect the loose ends to the unused left and right inputs on the stereo. If you do NOT use one of those devices, you'll need to find left and right audio OUTPUT jacks on the TV itself.
Many older TV's only offered audio and video INPUT jacks, as there was no need to send signals anywhere else since the TV displayed the picture and had an internal audio amplifier and built in speakers for sound. If you TV only has input jacks, there will be no easy way to obtain the audio output signals. While you could pay a technician to get them out for you, you might be better off obtaining some type of tuner or converter to do the job you instead and do it for less cost.
I hope this was heklpful and good luck! Please rate my reply. thanks.
Have you tried the another optical cable? They don't tolerate dirty connections or small-radius bends in their routing. THAT (and the expense of optical cables) is why I always choose coaxial connections when possible.
What does the TV really need from the receiver in all of this? Minimally, Component video for the DVD and managing the SA-HT920, not much else.
A TV is not normally an optimal source of audio.
Your broadcast TV-related sound would be higher quality and easier to obtain if you got it from the Cable or Sat box you probably have. Route ITS BEST (digital multichannel) audio directly to the SA and and its BEST (HI-DEF) VIDEO directly to the TV. You could also run vanilla analog audio to the TV so you can watch news in lo-fi audio on the TV.
The exact model of TV would be helpful to know as audio capabilities may vary.
Should you still feel the need to run TV-originated audio to the SA from the Viera through its headphone or audio output, connect that to any available analog RCA input.
Connection of a jack into the audio output will pass unmodified TV audio to the SA. That's a good thing as the REAL audio electronics needs an unmodifed source for best results.
No I don't think so . These are complex units . If your headphones work then is routing the sound to the output circuit then you should get sound out the output jacks. Are your speakers turned off or set to output to speakers b ? Give me more details at email@example.com I'll try and walk you through it. Larry's Electronics
Your TV probably has several different ways of connecting video. One is component, which uses three cables. They are red, green, and blue (RGB). The video output on your DVD player will match this color scheme.
Another scheme for video is composite (because it combines the red, green, and blue into one cable). Composite video is usually a yellow "socket". It is simpler to connect, but the video quality is noticeably poorer than component (RGB).
Another scheme is S-Video. This is one cable (round and black), but you will see four pins inside the connector (and four holes in the "socket"). This accounts for the three cables in the component scheme with the convenience of having only one cable. The picture quality is almost as good as component as well.
In your case, there may be confusion between composite and component. If you have red, green, and blue sockets on both the DVD and TV, then make sure you use them and connect them color for color.
Now for the sound, this is simpler. Red is the right channel, and white is the left. Make sure you connect red to red and white to white. Then, viola, everything will be right.

first try updating your drivers at www.ati.com, I have to ask you to double check the connector your using to goto the tv, if your using a S-video cable check the port on the card your connecting to, if there are more then 4 pin holes in the connector you need a pigtail to connect to your tv, many video cards use a cable that is sold seperatly to connect to a tv, connector look like a s-video connector and a s-video cable will plug into it, but instead of 4 pin holes it has 7, 9, or 12 connectors depending on the card, and the type of output the cable has. most are 9 pin with composit, s-video, and componite connectors on them.
