I was asked to help the neighbors connect their new TCL TV to a DVD player and a VHS player. The TV has a cable/antenna coax connector which is currently connected to his SD Comcast Cable box for normal viewing. Now.. both the DVD and VHS units only have coax outputs along with Yellow/Red/White (video-l/r audio outputs) and the new TV has none of these but has 3 HDMI inputs available. I am sure that there is a way to convert yellow/red/white output of the DVD / VHS players to an HDMI signal/cable but not sure what converter is needed.. Never delt with old equipment before.. Is there a converter of some sort available to convert y/r/w to an HDMI output cable.(they would need 2 of them). I know that y/r/w converters to coax are readily available and I might even have one in a junk box, but then they would need a A/B/C switch to utilize the one TV Coax input.. Not sure they could remember everything needed to do using that method to watch whatever.. Just trying to help them out..
