Thanks Bob.

Does anyone know if I can replace a  FBT 95-4134-01 with a 95-4134?

Max, 
=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0=A0What I would do first is
remove output transistor, fire up set see if you have 130V on collector
pad, if you don't trouble shoot power supply... If you have the 130V you
could have a bad fly....Remove sweep module, resolder all diodes caps
etc... Make sure you resolder the socket pins that cables plug into on
top side.. Not sure of model but there was a Zenith (two board set) set
that if it looses horiz drive, out goes the output transistor.. 
Hope this helps...

I found the HOT shorted and replaced it with a 121-1148. When turned on
it shorted out again. I have a schematic that is close. 
Any suggestions are welcome.
