HI,

 

I have a 46" Hitachi big screen that I am working on.  The model number is 46W500.  The problem I am having is that it will keep blowing the horizontal output transistor 2SC5909 after about one day of use.  Usually on some other sets I have worked on that has been caused by a bad flyback.  But,  I have no way to ring the flyback to check it.  Any ideas?  Does anyone have a schematic for this set?  Thanks in advance.
