Possible cause and solution
1. The TV is not connected to a signal source (DVB-C,
DVB-S/S2 or DVB-T/T2) or the antenna (terrestrial
or satellite antenna) is maybe not aligned correctly
respectively the according connection and distribution
equipment might show malfunction, incompatibility or
defectives.
2. DVB-T/T2: Active antennas need antenna power switched
ON or external power connected.
Antenna is maybe out of digital signal reception in your area.
Check reference from service providers about coverage.

(e.g. one or some channel(s) changed to another
transponder or are no longer emitted).
Incorrect values of LNB parameters.
DVB-S/S2,DVB-T/T2: The reception signal is too weak or
disturbed by electromagnetic, high-frequency, or other
interference signals. DVB-T/T2 : Disturbances caused by signal
reflections.
DVB-C, DVB-S/S2: The connection cables at the signal source are
too long (too high attenuation).
DVB-T/T2, DVB-S/S2: The antenna is not properly adjusted or got
misaligned after storm etc.
