No sound when viewing downconverted signal on TV from PMW-EX1

Posted by Robert Alvarez on April 15, 2008 at 11:29 pm

Hi guys,
Can you please help me.

I am viewing footage from PMW-EX1 on a television via Composite cable. I am downconverting directly on the camera, but I get no sound on the TV, no matter what channel I am on.

I get sound and no video via composite cable,
video and but no sound via component cable.

any help would be appreciated,
Robert

very very simple comment,
maybe you should check your cables again, you may have messed up the cables. or if you have another monitor/tv you may as well try in there.

cheers!

I have played video via composite on a TV with audio BUT I had to take the audio out of the AV output.

As Michael says, you should have audio out from the AV connection (Composite video+ L audio+ R audio). You need to set “YPbPr/SDI” to off.
The Components connection (YPbPr) can not carry any audio.

SONY EX-1 . SONY PD170
..and always a big mess on top of the table.

Thanks for your reply.

I do have audio from the composite, and I do get video from the component. What I can’t do is to get them to play at the same time.

I get sound when I switch the TV to video 2
I get video when I switch the TV to video 4

But I can’t get them to play together. I already tried all the monitor settings on the EX-1 and the YPbPr/SDI is off.

I’m trying to play it on a sony TV.
I appreciate any more help.

You need to check your TV manual to see what audio inputs go with which video inputs.

For example, I’m running DVI to HDMI cable from my computer so I can see EX1 HD from my NLE full screen on HDTV. On my HDTV I MUST use HDMI 1 input and patch analog audio to a set of inputs that are dedicated to that (HDMI 1) input. No other HDMI inputs with analog audio inputs will work.

Find which audio ins go with the component in and you should be OK.

I connected the component and composite on the same row of inputs on the back of myTV and presto, sound and video.
Thanks again.
