Hi David. Welcome to justanswer.
Since this is a old model, you don't have the facility to use HDMI or USB cable to transfer/playback on your Tv.
But what you can do is, use a card reader through which you will be able to do the same. This card reader is connected to your tv via usb connector which is on the card reader. You just need to insert the sd card on to this crd reader and can playback your videos in your TV.
YOU CAN BUY THE CARD READER FROM HERE
