Yes, all solid state circuitry, but CRTs (just like valves) had a heater, to get the electron guns going, so no picture until those had warmed up

The first black and white tele we had in the early seventies took ages to get a picture. Also if we had the tele on all day, something that rarely happened in the seventies, but if there was a test match, or Wimbledon and the tele was on all day the wooded frame surrounding the tele used to get quite hot.

I remember the old telly we had back in the 80s. If you turned it on after a long while, the sound would come on instantly but the picture would take a few seconds.
