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.



Some can be removed, it's easier to just disconnect it from the CRT though.
Slip a grounded screwdriver under the anode cup until you touch metal, then
lift up the edge of the rubber cup and disengage the clip from the tube.
