My Sky Top Box has decided to stay on standby, ie the red button is on all the time. Neither pressing the remote control Sky button , or using an old fashioned finger pressing the button on the box wil make it go green.
Happened to me a couple of weeks ago - it's not an old Amstrad is it??
After much googling I decided that some of the electronics had overheated and was knackered. I bought a replacement from ebay for �25 though so not all bad!
