Pay attention to the following notes when repairing the TV F2400/F2000.−
Do not leave the degaussing cable disconnected when repair a unit.
Conventional TV sets allow repairing work with a degaussing cable removed.
Turning on the power of a TV F2400 / F2000 with neither degaussing coil results in breaking a−
cement resistor which is inserted in parallel to the degaussing coil.
Be sure to connect a dummy load when removing a degaussing coil.
Scheme 1 :Use another degaussing coil to be connected for repairing.
Scheme 2 :Use a 6.8Ω 20W resistor, as the jig to be connected to the connector of−
degaussing coil.
Turning on the power of a unit with neither degaussing coil or dummy load results in
opening a fixed resistor which is inserted in parallel to the degaussing coil.
The following shows relations between the models concerned and the cement resistors.−
