Odd that you would have the problem with component. Did you disconnect the HDMI from the STB? Or, is it still connected?
Have you tried turning on the two devices in two different orders? Try a long delay between turn on.
Do you have addl boxes in the house? Can you swap boxes to see if it is the box?
Ec\ven without these tests I am beginning to think you may have a bad connection to the STB. Is is fed coax? Any way to try a cat5 connection?
