I have a Macbook Pro Laptop. Less than a year ago i was able to connect it to my tv with a DVI adaptor to phono into the TV. Using the same connectors and TV i tried to do this again recently and it doesn't work. It is definitely the laptop thats at fault because i got a loan of a different Macbook Pro Laptop and that works just fine. When i connect my laptop to the TV and press 'detect display' the screen flashes but nothing happens after that.
