Recently I have seen some issues with the 625 receivers freezing up after sowftware download and activation. I have also seen the tuner 1 side completely drop the a/v, the whole unit has also went into hard disk diagnostics, and has also popped up a hard disk failure message 015a. What I have found is that it is not a failure of the receiver but a software issue either due to software on the unit from the factory being corrupted ( most likely ) or from the software download from the sat.
To work around this issue you can do the following once or twice to clear it out. After activation is when you will see these issues happen, to clear it up you will need to do a hard reset by pulling the power cord and letting the unit sit unplugged for 30 seconds, plug the unit back in and this should clear the problem out. If it has gone into hard disk diagnostics and you do this it will clear out the tuner 2 modulation and reset it to air channel 60.
Dont do a front panel reset as it wont work, the hard reset is the only way to fix these issue's and this should save you from having to RA a new receiver.
