I had the TP technician come today to fix the issue of not being able to view channels that have been migrated to GSAT 24. The TP CC told me that it would require the receiver/LNBF change, but the technician knew that was not the issue and told me that the building's singular dish already has SUPER LNB 2.0 required for GSAT 24 signals. He did a master reset and changed the configuration from Universal to Super LNB, and those channels started working, even the yellow message box/TP help page. The signal quality isn't as good as it is on GSAT 30 channels, but he told me that it's based on transponders, and different channels will have different levels of signal strength.
I wanted to share my experience. I live in an apartment where all the flats have one big TP dish and for that Super LNB 2.0 is used instead of SatCR LNBF used for independent houses and dishes to receive GSAT 24 signals.
