Cable Auto-Detection (Toshiba 32AF33)

There is a switch built in to the jack. I think its
SPST so quick to defete BUT then the TV wont be looking
for S. It will always be looking for composite.............
Most likely switch goes right to a source switching IC.

What Zeno said.

I had a set once in my shop that insisted that something was plugged into the S video jack, when there was nothing. The switch in the jack was bad.

Had to order a new one from the manufacturer. It was crazy expensive at the time.

This was right after S-video came along on TV's.

Okay, I'll have to look at the PCB sometime and see if I can't intercept the traces coming from the switch.
