I have an DEC 92 RCA 52in P52151WK that won't start

The TV had been making an arc sound for quite some time when the set
was cold, however everything still worked fine. Which leads me to
believe that the HV splitter was having some issues? However now
while doing some test I fine that I don't even have power going to
the HV transformer. The only place I can seem to fine any juice in
the system is on main board to the right of the set (if looking in
from the rear). If anyone could make any suggestions I would
appreciate it. It is a classic case of worked one day and not the
next
