Yes, PSB is absoultely right.
I have the problems before. What happened to me is that my receiver lose my settings, like LNB info, my location info for some channels. What I did is that I deleted all the channels for all TPs, all the TPs but 1 for each satellite. Then I redo power scan for all the satellites. It solved all the problems and I have no problems so far. What I suspect is that the receiver doesn't have enough member to store all the info, a lot of TPs store in the receiver are dead and useless to store.
Question follow this for PSB: do I need to delete all the channels besides delete TPs? I delete all the channels too. It works good, but take longer time
