How to Get the Tv Display in Colour While It is in Connection to Highlander Set Top Box with Component Cable?

I had a problem with the old 20L05 – Wintal 20" LCD TV when it is connected to my set top box (Highlander HD with HDMI, Composite and Component port), that is, it displays black and white screen instead of colour even though I connected component cables to YRW jacks in TV. Now how can I display it in colour??

Suggestion:

The Yellow/Red/White connectors are not component, but are composite.
Component uses red/green/blue connectors for video, plus red/white for audio.

You need to use component (red/green/blue plus red/white) on your TV to use same from the box, or use composite (red/white/yellow) from the box to that input on your TV.
