KDL-40W5500 when watching turns off and then back on again

[Ntman2000]

I have the above model and have found that the screen will turn itself off and then back on again, this happens in about 10 seconds and the sound is effected the same way. I mostly happens when watching SKy but last time I watched a DVD it also failed on that as well.

Has anyone any ideas what I can do ?

Thanks

Have you checked the Presence Sensor setting?

You press HOME to display the XBM - select Settings - Eco - Idle TV Standby

it turns the TV off after it has been kept idle for the preset length of time.
