Richard,
That APW board may have bad solder on it.

Subject: [TechAssist] Sylvania-RSJ450-Ch#PTV325-high voltage comes up then 
shuts right down


Hello all,
This set starts to come on then shuts right down. The only thing I can detect 
is the high voltage coming
up then shuts down. I disconnected the wire from the hv transformer to the 
splitter just to see if it was
similar to the ctc 169 RCA sets with the shorted splitters and still nothing. I 
measured the voltage at
the vert output transistors and it starts to come up , then right down. There 
are 2 boards at the top .
The deflection board has 00705444 printed on it and the powersupply/highvoltage 
panel is a APW010SER8.Is
there any easy way to find out which of these boards is the culpret? There are 
no shorted output
transistors on either board.This thing is in somebody's basement or I would 
drag it to my shop but this is
not going to happen-just too heavy.I tried turning RP1 a little both ways just 
to see if the shutdown
circuit was critical, but still same.Seems odd you can push power button remote 
again and same thing. In
other words, you don't have to turn it off first like a
  regular
 shut down, then on again. Any help greatly appreciated.
