Why can I no longer use hdmi cable to connect to the tv

Anyway, with the introduction of ios 8.x, apple stopped supporting older a/v cables. You need to get the latest a/v cable with the correct firmware. There is a little chip in the a/v cable. go to the apple store. Buy a new cable. Verify the cable works in the store.

some people report success with a full factory restore.

Re-boot ipad.

Press and hold the Sleep/Wake button until a red slider appears, then drag the slider. Then press and hold the Sleep/Wake button until the Apple logo appears. page 128 iPad user manual.

force power down if the above give you trouble.

Hold down both the Sleep/Wake button and the Home button. Ten seconds or more. Hold until the Apple logo appears.

Hi Hdjukic,

The resource below explains the adapters needed to connect your iPad to the HDMI port on your TV. Another option would be to purchase an Apple TV and stream your content wirelessly between the iPad and your TV.
