Greetings group.
Sanyo ctv model CP21SA1.
All functions work fine except the picture is
black and white using the av input sockets.
All the tv channels show in colour.
I am wondering if a setting in the eeprom is corrupted.
Can anyone please tell me how to enter service mode
and what data should be there?
Thanks,
Russell Griffiths.

I'd be looking around pins 42 (Y-IN) and 44 (S-C IN) of the LA76818A
jungle IC. It looks to me like your IC is only seeing the luminance
component (Y-IN) of your video signal.

Re: Sanyo CP21SA1 CTV no colour using AV input.
Good news everyone.
The problem was solved by the Silicon Chip serviceman again (S.C. April
'05).
All I had to do was select the AV input,
then press the "recall" button on the remote
to select auto, ntsc or pal.
The recall button is a symbol of a tv screen with a bar in it.
Thanks to those who replied.
