Not likely F connectors. That is RF and I never saw a device that would direct convert RF to baseband video in the day especially in the prosumer market. This is a 525 baseband unit as the V interval label and sync timing indicator lamp shows. It needs sync somewhere via a camera input or a sync input. Probably RCA connectors on the back. The sync timing adjustment is to get the cameras in phase (tint) sync during a dissolve which is mixing two sources at once. Gotta get them matching in phase. The switcher may generate its own sync to reference to.
Open it up and look for bad solder joints and buldging caps in the power supply. Not much else can happen.
