Default samsung tv s51a chassis - smps problem, advice ?

extract from schematic:
http://www.fileden.com/files/2007/6/...20extract.jpeg

This Tv came to me with the fuse blown and the KA3S1265 chip missing.

I replaced the ic, but have not yet plugged in. Basically , doing a
few double-checks I saw that I have a dead short on the output of the
bridge rectifier. I have removed the rectifier, c805 and c806 with no
difference. So I'm now suspecting the smps transformer, as it is the
only thing 'in-cct'.

Does this sound reasonable? I've occasionally had these transformers
cause problems before in other Tvs, but haven't worked on many
samsungs. Any thoughts welcome.
