........... Update ................
Just done another test on the TV - leaving it on...
after 30 minutes the TV has lost its colour, gone dark and has red and blue lines running across it, horizontally

40 mins and the colour is still gone, but the lines have gone - so it is like a B&W TV.
50 mins the TV switched itself to standby mode, so I turned it on again to find the picture is perfect.
after 5 mins from switching it on again there is a red bar at the top
8th of the screen.
10 mins and the bar has gone, and saturation has gone down to about
50%
15 mins, the red and blue bars are back, and the sound has gone. picture is wobbling side to side quickly.
Again, any ideas?
Thanks. Demon.
