My new Sony 32FX65 is supposed to auto-detect the type of signal being fed into the AV ports. There is no manual way of selecting composite, S-video or RGB on each port like my old tv. When I set my NTL box to output S-video the picture goes black and white as the S-video kicks in, but the TV does not detect the new signal as being S-video and stays black and white rather than switching to a nice S-video colour picture. The NTL box goes into AV2 on the TV which is S-video compatible, but I also tried AV3 which is the same port type. Anyone got any ideas what's wrong and how to make it detect the new signal type???
