Our Sony 14" KV-M1420U television has suddenly lost its colour.

The picture is still perfect, but in monochrome. Sometimes the colour
will return if the television is switched to 'off' or 'standby' and
then switched back on. When the colours fails, it changes instantly
from colour to black & white, as if a switch had been operated. There
is no gradual fade.

This is usually caused by trimmer CT332. You can either clean and adjust
it, or replace it with a 15pF capacitor.

Nigels' right here. It's a common fault. You'll see a small 'pot' next
to the crystal. Note what position it's in now. With a trimmer tool, or
very small screwdriver just give it a tweak and your colour will come
back They go int
'dead spot' . You can put it back to it's original position and your
probably going to be o.k. Ideally a new oscillator trimmer should be
fitted but you'll probably be o.k. Although the crystal osc itself can
cause this problem and is common on other makes, on these Sony's it
always seems to be this little bugger.

Hope this helps,

Keiron
