Default Re: SCART problem with Ferguson TV set

I'm not familiar with that TV, but have seen something similar on an early scart Sony portable.

This would work fine on scart RGB, but scart composite (same socket) would produce a very colorful picture from 'some' satellite receivers.

Adding a 75 ohm resistor from pin 20 to ground cured the problem for the Sony, but for other TV's, adding 75 ohms in series with pin 20 cured identical issues.

Take all the usual precautions if you open up the TV, optionally, add 75 ohms in the lead if there's space.

From memory, my old workshop had a scart connector with a toggle switch & resistors to 'select' series/parallel or off, for the 75 ohm resistor. Crickey, that was a while back!

I still have a Sony portable from the early 90's, cracking picture on Freesat HD! (RGB).
