TV Doesn't Turn Off

[zeno]

Most sets if the relay sticks when you turn off most of the
micro is turned off & is only waiting for another ON command.
Therefor no channels, OSD etc.

Other possibility is the relay is only a degauss relay & ON/OFF
is done another way. Usually by turning ON/OFF the horz osc.

Best test is a new relay. Any with the same coil voltage from almost
any TV will work. You may have to extend terminals with wire.
Some sets are even drilled to fit 3 different styles......
