Thanks JB.
I am talking about all portable 14 inch analogue tvs, CRT, all suffer the same buzz with all boxes connected by scart.
Wish this had been pointed out when I bought the boxes, seems that if I can put up with a murky picture it will have to do, and certainly the buzz intensity changes as the picture changes.. But curious why the problem does not happen on larger crt tvs.

JB, please would you tell me why there is no buzz on larger tvs?
Is this 'overloading' also the reason that some of the small tvs have a problem with the picture, ie that if you imagine a square in the centre of the screen, approx a quarter the size of the screen, the two vertical sides of the box bulge in the middle?

thanks Brian, I am talking about set top boxes with portable crt tvs via scart at present, did not get a 'cushion' effect on the same tv on analogue.

Thanks JB and Brian, very good of you to give me such full answers. Seems ultimately I will have to discard all my old portables, but even with one of those flat things where you have to dance around the room to see the picture right I would still have to connect a box, Sky or Freesat, thanks to all the problems I have re consistent reception of Freeview, where even the 'light' transmitter at Aldeburgh occasionally gets knocked out with suspicion falling on Dutchmen.

Thanks JB.
I do not connect the third leg of the pot to anything?
All my portables have plenty of contrast, they don't seem to go pale like big ones.
I do not think I have the facility to select RGB/composite. I know with Sky there is that facility but not sure if the same with small freeview box.

Mike, thanks. I had one of those flat things once, I returned it to the shop. Whilst you could see the picture over a wide angle, unless you sat directly in front of it the picture was pale, and if you adjusted the thing to compensate for sitting at the side, it was no good for people sitting in front. But what irked me too was the way it showed the colour white. It was like looking at a fluorescent tube. You could tone it down, but never get any hue into it, ie make it a bit yellower.
Please see my previous numerous posts re Sudbury. It is ok in winter, this time of year signal on most muxes goes from 95% to zero in seconds. I had hoped when we went digital they would have overcome the problem of interference from Holland. No such luck.

thanks JB, I have several second hand ones, don't know what you call them, about 1cm square.

Here at Aldeburgh in a high location, I have a large areial which receives all muxes with signal strength/quality at least 95% from Sudbury. I do not use the Aldeburgh transmitter due to the limited number of channels In summer, one or two muxes often come up'no signal.' I think this is due to the Dutch.
Now, though, one or two muxes are again showing 'no signal' from time to time, and the Dutch are not interfering. Any ideas as to cause? Sometimes the BBC/ITV muxes go, other times other ones.

Thanks JB.
I have mentioned this before, I know.
All my small portables buzz on sound with a freeview box connected via scart, more so on bright pictures, but annoying all the time. Where I have a freeview box, eg Icecypt, which will also work via the aerial connection, there is no problem, although the Icecrypt makes a buzz via scart.
Where the other freeview boxes can only be connected via scart, is there anything possible to stop the buzz?
