How do you get picture on tv. When plug in hdmi plug to ipad get message, this accessory is not compatiable with ipad.

No picture appears on tv. Have goggled it, problem seems wide spread, but can't see any solutions.

Have tried powering up with plug, and without and plugging in later, makes no difference. 

The hdmi adapter is part no.  MC953ZM/A
 

In small print it has supported by ipad2, which is what i've got.
Brought it with ipad2, which is over a year ago, just got round now to trying on tv :(,

As was thinking good way to rent movies.
