I have a Rigel rsx-1056 receiver. I've had it for six years now without issues. My problem is that my OSD is not responsive. When I select the menu button from my remote the OSD appears on my monitor but only sometimes. I can scroll up or down the menu but when I hit + or - to change a setting it doesn't take. Other times the OSD doesn't show up on my monitor unless I unplug my rotel receiver. This used to work just fine. Any help is most appreciated.

hold down the enter button and the advanced surround button for 5 seconds or so and the amp will restart, the display will come up and hopefully it will be ok. its often caused by using speakers under 8 ohms, or damaged speaker cables etc

You will have to remove the small control panel printed circuit board from the front of your unit & inspect it for cracks on the board or bad tact switch/s.

ok i think i know how to get rid of it now, i did an ATX reset on it and it does go away HOWEVER as soon as you push the menu button again it comes back.

ATX Reset: unplug the main power lead then hold down the power button on the front of the monitor for about 10 seconds, plug the mains lead back in and then switch the monitor on.

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.
Thanks,
