Question about Logitech Harmony 550 Remote Control
Did you find a solution to the blank LCD on the Harmony 550 yet?
Well, I finally put together what worked for me:
1) pull a battery.
2) hold the power button down when you replace the battery - this should FINALLY get 'sefe mode' to show up on the remote
3) update remote
You may need to keep the battery our of the remote for 1 hour or so.
You may need to do this multiple times.
You may need to press power - OK - 0 <zero> at the same time before you do this (This is only if all else fails and you are really desparate and want to try anything. Try it with the batteries in only, Try it with the batteries out and hold all three down while you plug in the USB cable).
I did these various steps multiple times and it finally worked. Trye the 3 steps top down and then with each of the alternatives a couple of times for each alternative.
Use the 'Power' - 'OK' - '0' sequence as a VERY LAST resort - this really messes with the remote and may cause it to get worse and require you to do the steps many times before it finally works.
