No picture only sound/audio on HD channels?

Sky HD Box keeps loses picture when switching to HD Channels?

• This is a very annoying intermittant fault. When I change over to an HD Channel, my LCD screen turns Green with no picture, only sound. Engineer came out on Friday to reset the system, and said to contact him directly if if happens again within 30 days. It started happening again all day today (coincidence as problem was last Sunday too), so he is now coming out tomorrow to replace the box. This is a bit annoying as got loads of stuff recorded that I have not yet watched. Is anybody else having this problem at all?

• Answer:

  If you're not already doing so use a gold tipped HDMI cable to connect your Sky HD receiver to your TV.If you're using one already make sure your Sky HD receiver is on standby and turn it's power off and do the same with your TV.Then unplug the HDMI cable from the Sky HD receiver and from the TV.Clean the ends of the HDMI cable with a clean dry cloth then plug the HDMI cable back in.Turn the power back on to the Sky HD receiver and your TV and wait two minutes.Press the Sky Button on the RC,the green light should be visible.Wait 10 seconds and turn the TV on.Press Sky Guide on the RC and select a channel.
