Did you see where the spark was ?
Also look at the fuse(s).
Was the new module still factory sealed ?
For now about all I can suggest is pulling the power
supply & HV board and check for bad connections, burned
spots.
Without the manuals this is one of the hardest TV's to fix
ESPECIALLY now that there is no parts made nor tech
help from the factory. Add to that there is practically no
tech that ever worked on more than a hand full. We
were a Zenith dealer & I think I did 5 or 6 out of the
maybe 40 we sold over the years.
Sorry but you gotta remember this set has lasted 2-3 times longer
than it was supposed to.
