  Hello,

     I just wanted to post this question to see if anybody with
     experience with Zenith TV's might have any hints.  I did buy
     the SAMS sheet for the set and I will do an in depth troubleshoot
     in a couple of weeks.  I am a student living in the dorm at
     Florida State.

     Zenith Model A1936P  - System 3 
     I got this set which started taking time to warm up.  Now it doesn't
     work at all.  It makes a loud buzzing noise and creates sparks from
     the ground "feelers" that touch the top right corner of the tube.  Those
     feelers connect via a wire to the PC board socketed to the back of the
     tube.  This wire/trace appears to be connected to the chassis, however
     this set DOESN'T have a chassis connection on the plug.   Could this
     be the shutdown circuit being active?  I don't leave the set on for
     long and it leaves an ozone kind of smell.  My only guess is that it
     is the high voltage/sweep module.

  As always, any help is greatly appreciated.
