KDL - 40EX1 sound dropping out and noise scrolling down screen

[peterknowles]

Has anyone out there had an issue like I am getting with my Sony KDL- 40ex1.

When watch an input via the wireless sender I get the audio dropping out and every so often a scroll  down across the screen.

I have checked using different input and source's and they all do the same.

Any help participated

Thanks
