To do that, you need a digital camera, or camcorder, or maybe just a camera(MobilePhone Camera will do) and point the remote towards the cam. the reason why we're doing this is because we cannot see the infra red beam with out naked eyes... Try to see if there is a beam while you are pressing the remote button. If there is,maybe the problem is in your TV's signal receiver. But if there is no beam, maybe the infrared is broken.

It was very easy to replace the Infra red. To open the remote, you may need to remove the screws and locks. Some screws are hiding beneath the stickers and the battery. While others doesn't even have one just like mine. after opening the remote, remove the circuit board(The green color board) and save the screws.
