Hi everyone
So I had this same issue plugged my tv changed my sky q lmb to compatible freesat one.
Auto tune picked up 145 channels but bbc and some other channels showed invalid service.
Please try this as I managed to get rid of invalid service.
Settings the cog on your remote
Programmes
Programme Tuning and settings
Chang program mode to satellite
Notice you get new option for satalite settings
Go in to it
Select the satalite
Go down to lmb power and notice the stats on the right show 0% turn it on.. notice how signal strength and quality show show as a percentage.
Select done..
Reprogram/tune the tv again..
You should get all the channels back to normal.
My location is set to uk.
If it helps:
