Yamaha RX-V800 Composite Video Signal Problem

I have a Yamaha RX-V800 AV Receiver. When I connect a Composite Video Signal the picture I get is all wavy and weak. I though it had to do with an older device but new VCRs and DVDs result in the same problem. It doesn't seem to matter which input I use. Any help would be appreciated.

Hey there fontdude, I will begin assuming you are running your a/v cable into your receiver and then out to the TV or Monitor. If this is the case, I suggest you run the video cable direct from DVD or VCR device to Tv/monitor. You can still run the audio through your receiver. The nature of your problem was probably related to video signal strength being weakened as it ran through your receiver. Good Luck! Let me know how it works for you.

    Russell, running the cable directly to the TV solved the problem. The VCR works OK through the receiver, but I could not set up the clock. The clock display through the receiver and thence to the TV was there but it was too large to properly see the menu items. Anyway, your solution to run directly to the TV yielded the proper size display on the TV and I managed to get the clock set. Long winded, but thanks for a successful solution.

How to connect cd player to my Yamaha RX-V733

If the RX-733 is similar to the RX-773 then the Audio 1 and Audio 2 ports are audio inputs on the AV receiver. The AV 5 and AV 6 ports are for composite audio/video connections.

I hope this helps.

I have a Yamaha RX V800 AV Receiver is their an lip sync adjustment for internally with this amp.

This monster has a lot of built-in opportunities to tune or mis-tune the sound but nothing to deal with the effect you're addressing.

A discussion of lip sync:

  • There is extensive use of audio and video signal processing circuitry with significant delays in television systems. Particular video signal processing circuitry which is widely used and contributes significant video delays include frame synchronizers, digital video effects processors, video noise reduction, format converters and MPEG pre-preprocessing.
  • The video monitor processing circuit may delay the video stream. Pixelated displays require video format conversion and deinterlace processing which can add one or more frames of video delay.
  • A video monitor with built-in speakers or line-out may not delay sound and video paths by the same amount of milliseconds. Some video monitors contain internal user-adjustable audio delays to aid in correction of errors.

    Yamaha RX-V800 shuts down when any control button is pressed

    What if you DON'T use the remote? Does it shut down when just using it?

    If SO, you have a bigger problem.

    If NOT, it sounds like the remote is hosed - sending a code to shut off.

    Do you have another remote of any brand that you could set to do something simple, like change volume? Don't train it from the original, though, or it would do the same thing.

    Yamaha RX-v800 av receiver will not power up. Was playing and just shut off & will not powere up again. Was in a stereo/tv cabinet with closed glass doors. Cabinet compartment has vent holes in back....

    Mine did the same thing two days ago. No reason to suspect overheat as mine is in the open. Could be the power supply? Mine comes on after sitting for a while.

    When I am connecting my Wii with the receive, sound is coming okay but no video with I put in Yellow

    in your menu ther is a place to assign video inputs. i suspect that the video input you are using for your game is not set to composite (you say that you are using the yellow, that would only work for composite). Search through your video menu til you come upon the part that says assign video inputs. then pick the correct (number 1, 2, front panel, etc) input and change it so it reads analog or composite. that should allow you to pass the video portion. if all else fail you can always connect the video portion to the tv directly.

    No picture from wii

    The RX-V800 switches the various video signal types separately.
    Since you are feeding S-Video to the TV the composite (yellow) input from your Wii is not going anywhere.
    If you cant get S-Video output from the Wii then I'd suggest a simple Composite to S-video adaptor plug ($5 say). It worked for me with a Game Cube.
