I have a Panasonic TV that is about a decade old that has developed an
intermittent loss of raster. Only once could I get it to respond to a little
judicious percussive maintenance.

It has been along time since I have explored the guts of a TV. I have
experience in board level repairs an want to pull the circuit board to
inspect for poor connections.

The flyback looks as if the high voltage lead can be unplugged from the
transformer itself and would be more convenient than doing a disconnect at
the CRT. Is this feasible? Is the connection at the flyback a simple
straight plug in or is there a locking feature.

The nature of the raster loss leads me to believe that it is NOT the loss of
high voltage, but some other signal. The picture just blinks out sometimes
making a couple of steps toward darkness. The sweeps do not change and the
focus and contrast do not change.

I no longer own a voltmeter with a suitable high voltage probe.
