H1001 error messge - DirecTV

I have an old Sony Wega and when I tried to set up my Uverse with HDMI cable it came in for about 5 seconds and then drops out everytime. I have the component cables to use instead but what the right connection? I have several sources in the back of the tv and I've tried quiet of few combinations and have had no luck. Do I need the hdmi with the component cables? I'm lost.
