[TA-A] Re: 46W500 Problems

likely problems  1st if it is a split deflection and hv set then if the 
deflection transistor is the one blowing check for poor connection around the 
yoke pugs and the crimps  look for intermitent connection spots  ( arcing 
carbon)  If no t then determine if the transistor is running hot or fails 
catastrofically and suddenly without warning  jt js possible that the drive 
circuit is loose or the cap on the voltage dside of the drive transistor is bad 
 change it dont measure it. does it arc when it goes out? look for loose pins 
or defective crt or poor routing of wires. look for loose crimp connections 
around the yoke!  hitachi known problem

  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 electrolytics in the 
circuit and the flyback and the smps transformer. Does anyone have some 
expereince with this issue. Thanks.

Mike
