1 tv channel has no sound.

Check the sound format via sound options and change to a common one.

HTH,

Bryan

Or the PAL type selected.

Ken

Thanks for the replies Bryan and Ken. Both your suggestions have been checked with no luck.

No changes to the options or tuning has been done from when it was at the customers house, but it works fine here.

Is it possible there is some kind of local interference that could kill the sound only on one channel?

Russell Griffiths.

If the TV works on that channel it's not interference. Maybe it's overloaded - does it have a Local/DX or other attenuator switch? (Usually next to the aerial connector, but maybe via the menus). Was it connected to the TV via AV cables or antenna cable?

Ken

Ken. Yes I think interference is unlikely too ,when the tv is o.k. But, I am running out of any other ideas.

The vcr has no Local/DX switch, and there is nothing in the menus.

I don't think it should be overloaded, the tv signals are fairly weak in the area. The owner lives about 60Km further from the transmitters than I do, and the vcr has no trouble here.

The vcr was connected to the tv with an antenna cable, I tried an av lead, but it made no difference.

When I return to the owner, I think I will try a new masthead amplifier of a different type.

Thanks, Russell.

If you have an in-line RF attenuator - you can see if the other chs do the same with the signal weakened deliberately.

The only cures would be to adjust the mute setting , mod the circuit or replace the relevant IC.

When I first read your reply Phil, I thought you might be onto something.

But i'm not sure now.

I just tried an attenuator on the ant. in socket on the vcr here at the workshop. I started with 12dB and increased to 50dB.

The picture was very snowy at 50dB, but I still had sound.

Russell.

Just a thought, your friend doesn't also feed Austar (or a game box or some such) in via RF? I can't see any other form of interference wiping out the sound. Maybe an AV sender or game, etc in another room over there...? If you are heading back to try it out, I'd suggest you take another VCR which you know works at your place. Set up with the same channels and output on the same RF channel. Maybe change the output channel when there. By the way, what channel is it outputting on?

Cheers.

Ken

Thanks for the suggestions Ken. No, there is no Austar, games machine or av transmitter.

All your suggestions will be kept in mind when I return. I think the RF output channel is 67.

Thanks, Russell.
