My Experience Might Help Someone

[SpencerCat]

Last night I noticed that one of the tuners on my 721 would not display a picture. I could see the EPG and the info screen at the top of the black screen, but no program.

I did a switch test, and everything appeared to be OK, but there was still no picture on one of the tuners.

This morning there was still no picture on one of the tuners, so I did a front panel reset, and, to my amazement, that solved the problem. Both tuners are now working normally.

Yup on the 721 sometimes one of the tuners goes to sleep and it forgets how to wake up so you must prod it to wake it up.
