RGB input colour problem

J

Jenny Talia

Guest
I have just bought a Daewoo Setpal Freeview box (Digital TV decoder for
non-UK readers, think of it as a satellite or cable box) and when connected
to my 5 year old JVC 29SX2 T.V. using a SCART input that takes RGB according
to the manual the picture colour is messed up. That is to say white is
yellow and blues are brown, general yellow cast to picture !.

If I select composite output on the Daewoo box rather than RGB then the
picture colour is fine via the same T.V. SCART input socket.

Any ideas anyone, one of the boxes using a "non compliant" pinout so RGB is
muddled up ???.


Thanks for any ideas

Most likely a damaged cable with the pin carrying the blue signal not
working - try another scart cable or try reversing the cable.

Is the "red" pin on your SCART lead bent or broken off? It sounds to
me as though the "red" signal isn't getting through.

When using the RGB (Red, Green, Blue) output and the blue output is
missing the picture will have a yellow tinge

The wire associated with the blue output may be open circuit or shorted
to ground in the cable, or the plugs may not be properly mated. If you
have another cable try that first

See
<http://www.amacleod.clara.co.uk/test/>
which shows two copies of the same photo. the lower one has had the blue
component removed.

I'll go along with Simon and say it's the blue.

I have just bought a new Panasonic tv as a replacement for my old JVC
(older than yours, btw :) ) Using the same scart lead I get a brilliant

RGB pic from my dvd and s/vhs recorder, with the JVC the RGB pic was always
rubbish. The JVC manual does warn that the RGB input might not work with
all
devices, mine never worked with any!

I get a similar problem. It seems to be caused by my Panasonic TUCT30
digibox. I have two DVD players linked up and going through it. I am
getting a scart box for each RGB device (two DVD players and a DVD Recorder)
and then go to the TV.

It was working fine before I put the digibox into the setup. I think the
scart socket is dodgy on RGB. Composite is fine.

I got too much equipment in one place and going to the same TV which doesn't
help.

Blue missing = Picture has yellow cast
Red missing = Picture has blue cast
Green missing = Picture has purple cast

See
<http://www.amacleod.clara.co.uk/test/>
which now shows examples of all the above cases.

As a wild idea, try using another SCART lead. Make sure that it is fully
pinned.

Sounds to me like you've lost the Blue signal - check that pin on your SCART
lead.

FYI Yellow is made up of R+G. White = R+G+B.
