Sharp CF-27S10 burnt D502.
 

Came in fuse softly blown, shorted HOT (Q602), Replaced these and
several caps in the regulator circuit. Turned on to be greeted with
smoke. HOT and fuse still holding but the D502 broke in two without
any heat damage which is interesting.

Anything I should look for to get Sharp fixed? Since Sharp is not
friendly to deal with for our TV shop so I came here asking for info.

This is the one of those Sharp's strange two transistor switching
regulator that controls pair of exposed windings around the flyback's
core. I need documentation on this theory of operation especially for
Sharp's unique regulator? I have another Sharp TV with even worse
condition (regulator section blown up).
