Hi,
According to the User manual a UE22 code indicates a failed software update. (scroll to p.75).
If you haven’t tried to update the firmware in the receiver then perhaps the wrong buttons have been operated on the remote control which placed the receiver in the update “mode”.
Have you tried operating the Home Menu button (or equivalent) on the remote to see if this restores it back to normal?
As you mention that you are using a Logitech remote , has it been in use for a while or is it a new replacement for the original remote that came with the receiver?
If it is a new remote perhaps the wrong code which matches your receiver, has been selected in the remote and by pushing what was thought to be the correct buttons has actually caused this to happen
If you have been using the remote for a while with the receiver then you may have to go back and set up the input selection again. Go to p.28 in the manual.
If this also fails you could try “resetting” the system back to its’ factory defaults state and setting it up again. (Scroll to p.55)
Last resort if all else fails to work, is try “updating” the software, as per the link above, in case the software in the receiver has somehow become corrupted.
