Question about Harman Kardon AVR 240 Receiver
I have an AVR-247 and the 480p output works fine on both component and HDMI. However, when I change to 720p the screen goes black and I can't even get the OSD to come up (though the receiver displays 'OSD' on the front). This also occurs with both component and HDMI. Damn. Help appreciated!
The problem might be that the set can not handle the change in signal. Try setting the AVR-247 to 720P first then turning on the set. Or manually set the TV to receive 720P then change the AVR. TI believe that you have a connectivity issue where the two units are not speaking the same language at the same time. Update this with your results and please post the TV make and model.

IMPORTANT NOTE: If the AVR's video output resolution
is set higher than the capabilities of the actual connection,
you will not see a picture. If the best available video connection
from the AVR to the TV is composite video, press this button
and change the resolution to 480i.
