Junior,
Pin 52 is the vert. out on IC 101. The waveform should be 4.6vp-p(5ms) on
pin 52. I see you've already replaced C455, also replace C451(220m-16v) off
of pin 1 of output IC, if you don't replace both these caps when replacing
the output IC, the new output can fail immediately at turn on. Also, use
only a Panasonic original LA7836.
