[OT]RGB TV and colour adjustement

["stevecrick2000" <steve.crick@xxxxxxx>]

Sorry for the OT post, but I am sure I can get an answer to this.

Is it normal for a TV not to allow you to adjust colour levels on
the RGB input?

I ask because my new TV (Panasonic TX32PL1 - EURO-4 Chassis) does
not allow this; which would be fine but the colour level is a tad
high from the RGB (TiVo) input, and I want to lower it.

The colour slider moves up and down on the RGB input, but the
picture simply stays the same; but it works fine on S-video an off
air.

I would like to know if this is normal or a fault so I can tell
Comet (I have only had the TV a week).

Anybody got a EURO-4 Chassis Panasonic can confirm this?

Many thanks - Steve
