-   Sharp 27J-S260 made dec 1997. Pic & sound fine. But high
pitched noise/loud squeal (>10KHz) intermittent when TV
is on. Torquing the cable connector and/or pressing on
various parts of the external case can make it go away,
or louder. does not seem to be at all related to the
picture, or whether signal is from rca jack composite
or barrel cable connector. Been like this for a long
time, but pic is still great. Using rubber bands to keep
pressure on the threaded cable connector with some success
at living with this very annoying symptom. Many, many thanks
in advance for your advice/expertise.
