my tv has red white and yellow but not red blue and green .my onkyo receiver has red blue and green, how can i hook my receiver to the tv to get the component signal
A: As others have said, you can't. However, there are converters and what you need is component to composite video converter. I just did a quick google though and the ones I found are costing more than a new TV. Give it a try yourself, you may be able to find something cheaper. It certainly is possible.
