My dad has a Hitachi 42HDF52 and a standard Directv receiver. He hit some button on the television's remote and now no more directv. Directv's customer/tech service is no help. The screen says to go into directv menu and select channel scan. This does nothing. Neither does resetting the receiver. It has to do with the setup of the actual television. My dad says someone used to fix this (yes, it's happened a few times) by using the menu button on the actual TV. I have tried most of the options and am obviously missing something. If this if familiar to anyone, PLEASE PLEASE HELP!
I suppose it would depend on what button he hit, so we'll start with the easy one first.
He may have accidentally changed the TVs input. Make sure the DirecTV box is on and use the input selector until the picture shows up.
If that doesn't help, can you tell me how the box is connected to the Plasma? Or, can you make a better guess as to what button was pressed?
