Hi. I purchased a RGB to Scart cable to connect my digital sky decorder to tv. Digital sky decorder has Scart cable and tv has component input. But, there is no signal...??!!?? Does that mean the cable only send signal from RGB to Scart? Does that cable also send signal from Scart to RGB? If it cannot. it's only that cable or whole RGB to Scart cable only send signal from RGB to Scart? not Scart to RGB? I need your help desparately.. Thank you.
