For old TVs not having composite AV inputs can it be possible to connect audio input to the audio amplifier and video input to the video amplifier directly on the PCB ?

You cant just add more inputs then what is on the pcb, you cant just make the circuitry appear out of magic.

Most old TVs came with composite (red, white, yellow) and some TVs pre HD had component (red, blue, green, red, white). There is also svideo plug which they make a passive adapter for to go from svideo to the yellow of composite.

If the TV is really really old then it would only have a coax in (or even two screws that you had to plug a coax adapter to. You can use an RF modulator to turn composite into this type of input.

The old TV has only RF input from antina or VCR and no AV inputs to connect through RCA cable. My guess is that AV inputs are analog and unmodulated. Therefore audio signal can be fed to audio amplifier and video signal to video amplifier at the point where video signal is separated from RF signal.

RF modulator is an option. But here I am trying to know if modification can be done to TV by feeding the video and audio signals to the right points on the TV's PCB. It can be possible if the required points are available and the signal formats required at those points matches with the signals from AV cable (RCA cable).
