I'm facing strange issue since 2017 on SAB HD , Ten1 HD , Ten3 HD .. watching these channels suddenly signal goes off around 8:42pm, 8:52pm, 9:12pm, 9:22pm and changing channel and coming back to these channels again starts working fine again with full signal strength & quality. Issue happens sometimes Once or twice in a week. It used to happen with Huawei hd box till 2019 then I changed to Calcomp HD box but the issue is still there. Although after that in July 2021 I changed dish antenna complete wiring with new LNB also dish installed to new location New HDMI cable.. the only thing left is adapter which is working fine since 2016. But after reading ur comments I'm thinking should I change adapter? airtel Engineer never adviced me to change the adapter!!
