I have a late '80s vintage Philips CP110 Tv , which works well, but
the colour is weak, even with the saturation control set to full the
picture is only just more 'colourful' than B&W!
. is this likely to be something like a low voltage to the RGB
stage,or something more serious?

If the A1 control is set wrongly, some of the older CRT types can look
'washed out'. Sometimes, beam limiter problems can give the same effect. A
fault in the ACC circuitry will do it, and sometimes, a mishapen sandcastle
pulse, which used to be quite common back then. Often down to a resistor in
the HOP stage, where the pulse is 'constructed', having gone high.
