Hi bgl, rebooting the receiver helps sort out issues with the receiver, so rebooting will help. Take the power cord out for about two minutes, tighten all other connections from the wall to the receiver, from receiver to TV. Allow 20-30 minutes for the receiver to fully restore services. You will probably get the picture back fairly quickly, but the guide make take awhile longer.

What is the model of the receiver? Has this issue just started happening?
