You may have lost the "network tuner", which isn't the same as the two SAT tuners.
There isn't an easy way to check, so you'll need to reboot, and at the receiver "running self test" screen press select and go into the guided test menu.

Ran the diagnostics and all tests passed. Sat tuner Net (84%), Sat tuner 1 (90%), Sat tuner 2 (89%). Played the AV from Sat tuner Net during the test.

Then you don't have a problem. :lol: :lol:
Maybe pull the power cord for 10 mins and then see what happens.

Nothing happened after pulling the plug. Took the rx to my Mum's and plugged it into her working dish (same as mine). Same problem. Plugged her rx back in and it booted up just fine. Hers is also an hr22 and it booted in less than half the time. Thoughts?

Well whether it thinks it's working or not, it sounds like it needs replacement.

So, as a last-ditch effort before making the call, I did a Reset Everything (from the standard menu). Wiped the settings and all saved programs (sniff). It seems to be working a little better now - I'm wondering, is it possible that, after three years, the disk has become so badly fragmented that the unit became unusable? Is this the only way to wipe the drive or is there an alternative method to really wipe it / format it, etc?

You can no longer reformat an internal drive, but there is an extensive disk scan that can be done. When you reboot and hold down the record and down arrow buttons on the front panel, you should/will see a screen showing the disk scan in progress. I did this with a 300 GB drive and it took about 2.5 hours to complete.

What will the scan accomplish?

:shrug: it does seem to be the most intensive disk scan I've seen the receivers do. It "looks like" it reads/writes to every block on the drive to check its status.
