<CONTENTS>
Pay attention to the following notes when repairing flat CRT a TV set.
When repairing a unit, DO NOT LEAVE the degaussing cable disconnected.
Conventional TV sets allow repairing work with a degaussing cable removed.
When repairing a TV set with flat CRT, however, the instruction below must be followed.
The instruction is provided on the service manual also.
Make this known to all staff concerned.
Notes on repairing:
DO NOTturn on the power of a TVset with a flat CRT whena degaussing coil is removed.
Be sure to connect a dummy load when removing a degaussing coil.
Scheme 1: Use another degaussing coil tobe connected for repairing.
Scheme 2: Use a 6.8 ,20W resistor, as the jig to be connected to the connector ofΩ
degaussing coil.
Turning on the power of a unit with neitherdegaussing coil or dummy load results in
opening a fixed resistor R848, which is insertedin parallel to the degaussing coil.
The following shows relations betweenthe models concerned and the cement resistors:−
Model name R848 Type
TV F21ST1 33 /2W cement resistor−Ω
TV F25ST1 27 /2W cement resistor−Ω
TV F2400−
TV F2000 56 /2W cement resistor−Ω
If the resistor opens, noises appear in horizontal directions onscreen.
Also pay attentions to information about the flat CRT models to be releasedin the future.
Component values of the dummy resistors will beannounced as occasion arises, and will be
contained in the service manual. Always take noticeof the information.
