Re: Ferguson tv 3755
Pretty sure that's a TX9 MkI. As John says, the fuse will be under the cover that forms part of the mains input plug. It's likely to be blown. Then the fun starts as the crowbar could have fired. Check for obvious shorts (bridge, degaussing thermistor, thyristors, series diode) then monitor the HT and see what it gets to - 117v is about right. A variac is very useful here. It's best to reduce the HT preset first (this can become intermittent causing random fuse blowing), but ISTR that the direction of rotation changed during production so I can't say which is the right way! You'll need a good stock of 1.6A antisurge fuses - the ones with the spring inside. Another very common fault back in the day was the small mains filter coil near the input connector. That can overheat and conduct, blowing fuses, though I think it's on the live side of the mains switch.
Of course it's just possible it's a Mk3 which has a redesigned PSU. That uses a chopper transistor on a heatsink and a TDA4600 so is easy to spot - the older version had neither.
