Loss of picture colour not teletext or channel indicator
 

**************************************************
Hi
I have this set and a similar problem. Just want to check it is the
same.
TV normally goes into black and white mode when my son is using a PS2
plugged into AV2 at the front.
When this has happenned the normal TV picture, AV2( DVD scart
connection) and AV3 (front connections) are black and white.
AV1 however (freeview digibox scartr connection) is still colour.

Is this the same problem?
cheers

I don't know what the original problems was, maybe a problem with my
newsreader has split these threads.

The Freeview box is probably using RGB which cannot go 'black and white'
(as such). Normally only one scart support RGB, so it better to chain
the devices if you have 2 scart sockets in some of them. DVD will be
much better on RGB also, I don't know if the PS2 has RGB.

Possibly the TV is incorrectly detecting the signal from the others as
NTSC or Secam, or the TV is set to S-Video and you're giving it
composite. Also try only connecting one device at a time.

You need to check the setting in the TV and the setting on the devices
match. Although the fact that the other devices are affecting the
inputs not connected to it sounds like a fault or just bad design.

Standards:
Composite video - black and white + colour signal on one coaxial cable.
Colour can be PAL, SECAM, NTSC encoded
S-Video - Black and white and colour signal on 2 seperate cables. Again
colour can be PAL, SECAM, NTSC encoded. Better quality than composite.
RGB - No encoding, 4 or 5 cables usually in scart, best quality

RGB has some special problems as its designed for OSD/teletext
generation, ie mixing signals. It could be the freeview STB is pulling
the RGB line high all the time and the TV is allowing this to affect the
other inputs. Make sure you put the STB into standby when not using it.

Not your newsreader fault!

This is an old thread from 23rd March 2006. The OP is using the *Banter
online web interface which is appalling at maintaining threads thoughout
all the usenet groups unfortunately echoed to it. Sane people don't use
this system, and install a newsreader like you have. Thunderbird is a
good choice ;-)
