The set in Girl Interrupted I believe is a solid state 1970's Zenith chromacolor II with the older-style 23" picture tube, so it would come on as quick as the CRT warmed up...also it may have had an instant on circuit on the CRT filament for even quicker warm up.
Many of the 60's tube type sets had a circuit to keep the tube filaments lit at lower voltage when the power switch was off to indeed allow them to come on in a few seconds.
The really old tube radios with directly heated tubes are instant on---as soon as the filament's glowing, the tube is working, same with battery powered tube type radios.
