i am using the decoder adv7180. If the pin SFL (pin 2) of LFCSP–40 is not connected does this affect the free run test??
Because if i remove the source i don't get a blue screen.
SFL is an output from ADV7180. I don't see how it could affect free-run. Free-run won't work until after the part has locked to an input at least once from power-on. I don't think that is your issue since you said "if I remove the source" but I thought I'd point it out.
