The SC-PT170 is about 1 year old and has worked OK. It was conected to a new Palsonic TFTV327FHD television 2 days ago and colour was fine.
The B&W problem occured when I turned it on tonight. With the SC turned off the TFTV presents in full colour.
The SC is connected to the TV with a single video cable (not HDMI) the sound comes straight out of the SC to the supplied speakers.
Cable is an audio / video cable (Red / black / yellow) with the yellow plug used.
There is not an adaptor at either end.
I have replaced the cable and double checked that it is plugged in firmly at both ends.
I confirm that the Panasonic is set on PAL
Please post back results.
Yes, yellow jack is in Video jack
I cannot find the TV setting for PAL
Yes TV is set to AV mode
