Out of Range

[Khicksy]

Hi I have had my Sony Bravia KDL32S3000 for a few years now and it is still working great.  I decided to connect a Blue Ray DVD played to it via the HDMI socket, but it keeps showing "Out of Range" every time I turn the DVD on.  I have tried 2 DVD players of different makes (toshiba & Sony) but it has not solved the problem
