Sanyo TV model HT32546, Ch. 32546-04 HV problem
 

This set came in for repair out of warranty. The customer who was
referred to us by Sanyo said that he heard a "slight crackle" sound
and the picture went to a small circle then the set went dead. So Far,
I've found Q402 shorted, D404 shorted, D406 shorted and R484 open.

Does this sound like perhaps the tip of the iceberg or anything known?
I'm troubleshooting this without a schematic so I'm not sure what else
these parts may point to. Any further insight on this problem and
perhaps a schematic anyone might be able to offer would be greatly
appreciated. Thank you very much.
