This television displays a strange image and sound distortion just after it's been turned on, as shown in this 5 second video.
It may do this several times, and, rather disconcertingly, seems to be slowly getting worse.
Note - the slight flickering is an artefact of the video recording.
I'm using a computer output to show the fault, but I get the same behaviour on broadcast channels if the computer is completely disconnected, and turned off.
I suspect a warming up effect. Any ideas?
Sylvia.
