I have an old Sony TV with no SCART socket although it does have AV red white yellow sockets, an STB box with 1xSCART, a Sanyo VCR with 1xSCART

The STB and VCR all have RF output potential, and STB works well using Ch48 RF output to TV, while it gets interference using any other, 21-70, RF channel

However the VCR sound gets interference on any of its RF output chanels, 21 - 69, even when taking out the STB, and using Ch48. On many of the settings the test lines are clear and not wavy, but there is a contant 'buzzing' sound, louder or quieter but still present on any channel

I can record Freeview progs from the STB using SCART from STB to VCR, but cannot play them because I cannot successfully connect VCR to TV

I wondered:-

1. What might be the cause of the problem?

2. Is this feasible: a lead with a SCART socket one end, for the VCR SCART output socket ('to TV'), and banana plugs on the other end to plug into the red white and yellow input sockets on TV?

Guidance would be appreciated

Yes - what you want is a SCART to Phono lead (the plugs are called phono - banana plugs are something different!). Such as http://www.maplin.co.uk/Module.aspx?...28102&doy=11m4, but you will also find these types of leads anywhere like Currys, Comet, Tesco, Woollies etc.

Bit of a long shot, but you mentioning that you get a buzzing sound on the RF from the VCR no matter what you set the output to, has got me wondering if you've got too much signal coming in.

Are you're TV pictures quite good when you have the aerial plugged directly into the TV? Or do you know if you live close to your local transmitter? If it is too much signal, a signal attenuator on the end of your aerial cable before it goes into the STB could help.

This scart switcher will allow this type of set up:
VCR scart ---> switcher socket 1
STB scart ---> switcher socket 2
switcher phono out ---> TV phono in

Set up RF like this:
Ext aeriel ---> STB RF in
STB RF out ---> VCR RF in
VCR RF out ---> TV RF in

You can then record from STB (digital) to VCR over scart while watching terrestrial, or record on VCR from RF (terrestrial) while watching digital.

Thanks I had wondered about the correctitude of the term 'banana plugs', just that for some reason it stuck in the mind!

The link is very helpful, I have tried something similar but, while it did not not work, I noticed the SCART end did not have all the 21x 'prongs' (?) also it looks as if the switch will give more hope, guessing that one happened to be back-to-front, so-to-speak

Will report any progress. Thanks again

Thanks, the signal is apparently good and strong, by the way especially recently on freeview for which I originally needed a booster to get it to 70% (professionally fitted, and now hidden somewhere under more inches of insulation in the loft) Signal has shown 90% for several weeks, so maybe 'They' have boosted the transmitted digital signal even before analogue switchoff - haven't seen it mentioned anywhere though

However the STB doesn't buzz with its RF output set to Ch48... one would have thought that its sound (presumably originally digital sound) signal is being selectively boosted (compared to the originally analogue VCR tuner's sound, which is the one that does buzz)

In response to your enquiry, the Tele's picture is indeed good with the aerial plugged directly into it, and its native analogue tuner produces normal sound too

Thanks again for your reply and comments

That is very neat. I have got the RF set up like that, and thanks for the explanation of the possibilities which look just what was needed

May I take it that the switcher can connect any two sockets on it, out of the 3 different ones to be used in my own case, and that 'TV phono' does mean sockets for Lphono, Rphono, and Video plugs on the leads to the equivalent 'in' sockets on the TV?

I guess how the buttons work on the one you linked to, but cannot work out what the 'automatic' switcher, shown as an alternative below it, would do. Would that be any good too?
Many thanks

Yes, there is usually one of the sockets marked VCR or recorder so that any of the devices (say, Sky or STB) can be picked up by the recorder while the output is primarily sent to the phono connected TV. The phonos are as you describe (L/R audio plus video).
