Sony CRT TV switches between colour and non-coloured / grey screen
Hello.
We have an old Sony Trinitron CRT TV, 72cm maybe 5 years old or more and since some years a problem. The problem is: The TV switches from itself between coloured screen and grey screen, maybe every half an hour. Does anyone has an idea what the problem is? Maybe just a contact problem, but in which area? Thx. |

If that confuses you, then you must at least give us the model number of the set, SONY make many sets. |

Mine switches to BW if I change the DTV channels quickly. Selecting Fox News usually brings it back .... go figure.
