Your putting it on active channels for an antenna/cable, and/or connecting to A/V Inputs AND switching the set to "Video."
Is the channel number and "Video" being indicated correctly (not sure if set has OSD or panel display-can't find much info on set at all)?

What is set's vintage? (year made).
Is "raster" a blank snow-free screen (as opposed to a snowy raster - like set has when tuned to unused channel)?

I assume there is NO AUDIO either. Any Blinking timer light code?

Could be anything from a B-Plus source being missing, the T-Chip (TV processing all in one I.C. - may be CXA series) has a defect, something affecting the communication (I2C) bus between Tuner/micro/EEPROM/T-Chip.

Without a schematic or at least IC numbers ...
