but still i have this problem. I
also have a TV which chages the colour of the screen to black. for
example i am watching a film and then the brightness of the screen
begins to reduce until it is totally black. I think that a part has
gone on that. If anyone knows of the part the needs replacing could you
please tell me.

No chance, you need to do some fault finding to find the fault.

I have tried. I tried changing the settings from the Focus Unit. When i
chage the level of current going into the screen it seems to make it
worse. so i have reduce that. It has made the pciture darker and it
takes a little longer before it starts changing the brightness. I
reduce the focus as well and all that does i prolong the effects. I
have looked at the circuit board there are obvious signs of a blown up
part. I have checked the current on the board in different areas it
looks OK. There is a Switch on the board it have no label on it so i
didn't mess with it but it might help if anyone knew what is the job of
switches in TVs. I looks like the sort of switch you would find on a
toy. I will try and get you a picture to help
