Replaced Kit 54 and soldered Daughter board but DUMBO fitted it back wrong way round and it blew again. Fitting new Kit 54 and new Daughter board in case I knacked it. On checking round I find D210 is SC now. Can anyone identify what type of diode this is? Have downloaded diagram from Hitachi but no parts list with this diode on. Myself and another colleague are struggling with the same problem.Any info welcome. The PSU is a MPF7409L
Thanks Dave
