Sky box / tv issue

[Griff Boy]

Hi,

I've got a small but annoying issue with my Sony LCD tv.

Basically it is connected direct to a sky hd 1tb box by an hdmi lead. The problem is that the tv occasionally goes black for a couple of seconds and comes up with the 1080p symbol, then goes back to normal. It's really annoying!

It seems to be resyncing with the sky box? Is there any settings I can change to stop it happening?

Cheers in advance.

Come on guys, surely theres a happy medium between £4.99 and £3k! :-)

Cheers for all the help, Ill try swapping out the HDMI cable this weekend. Can they fail in use? as in this ones been installed about 5 years now...

cheers again
