yes I put compuond on it. It is defintely transferring the heat because the
heat sink gets so hot it will burn you after only running the tv about 10
minutes or so.

its running but the 2SC5909 is still getting really really hot so I don't leave
it running very long because it will blow it. And the only place I found that
has them at a reasonable price is in the UK and it takes 2 weeks to get the
part.

Hi all, I am in need of some help. This Hitachi 46W500 is kicking my butt. It
keeps blowing the hv drive transistor. I have replaced all the electrolytic in
the circuit and the fly back and the smps transformer. Does anyone have some
experience with this issue. Thanks. Mike
