Notes on repairing flat CRT TV set

REF.No. :G − 99 − 076 − E0

DATE :02. MAR. 2000

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 NOT turn on the power of a TV set with a flat CRT when a degaussing coil is removed.

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 R848, which is inserted in parallel to the degaussing coil.

The following shows relations between the models concerned and the cement−resistors:

If the resistor opens, noises appear in horizontal directions on screen.

Also pay attentions to information about the flat CRT models to be released in the future.

Component values of the dummy resistors will be announced as occasion arises, and will be

contained in the service manual. Always take notice of the information.

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 6.8W− 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

In this set, after successive operations of changing the channel are made using the remote

control, there are times when the remote control becomes ineffective.

Please take the following countermeasures for such sets.

Further, although this condition gets recovered when the AC cord of the main unit is removed

and then inserted again in to the power socket, the same condition occurs again if the above

operation is made again.

Please replace the component with the one specified below.

Due to unstable of frequency of broadcasting, it may not be able to receive specific channel.

In this case, take the following corrective countermeasure.

Can not receive specific channel in both AUTO TUNE and MANUAL TUNE.

It becomes possible to preset channel by AUTO TUNE by replacing micro processor.

When AUTO TUNE preset is not possible, MANUAL TUNE preset is available.

A beat noise problem may arise by influence of the power supply circuit.

Especially, this problem will happen in low electric field or VHF LOW channel.

To avoid being influenced, modify the power circuit as following countermeasure.

1. Replace the FB830 and FB831 in the secondary stage of the power supply to the jumper wires.

(see fig.2)

2. Remove the JW606 and JW608 which connect the GND traces.(see fig.3)

REVISION : Additional description in Countermeasure

Take the following measures with regard to complaints that the power shuts off or cannot be

turned on in relation to the model above.

1. Check the condition of the TV set (whether it is in the protection mode against a power supply

error) by the following steps a ∼ e.

a. Check that the power cannot be turned on from either the power button on the TV set or the

remote controller (stand-by: a red LED goes on).

b. Press the "TEST" key on the jig remote controller to see if the power comes on (if it does not

come on, the microprocessor may be broken).

If the protection function is on during power supply error detection, pressing the "TEST" key

makes the LED flash in green and an AGING display is shown.

Pressing the keys on the remote controller in the following order instead of pressing the

"TEST" key will also bring up the AGING display.

"ENTER"

"AV MODE"

"SLEEP"

"MENU"

"POWER"

c. Once the AGING display is shown, press the "TEST" key to erase the AGING display and

disconnect the power supply cord.

∗If you have had no problem in operation up to this point, there is no problem with the

microprocessor and the EEPROM.

d. Connect the power supply cord.

Check that the power is turned on by pressing the "Power" button on the TV set / remote

controller (complete the procedure by performing steps 2 and 3 below).

e. If the TV-set is still in stand-by status, the protection function is on during detecting an error,

so check if there is a problem with the power supply system.

2. Check the R617 resistance (when the resistance is excessive or OPEN, a power supply error is

detected).

When R617 is 1/8 W, change it to 1/4 W (this has already been changed for models with Serial

No.S∗∗∗∗0C∗∗∗∗∗ or later).

∗When replacing the EEPROM (IC3), refer to the "Description" in the table below to select an

appropriate EEPROM. Different models/specifications require different EEPROMs.

Refer to the NOTE below.

NOTE

Turning on the power after replacing EEPROM activates data writing between

microcomputer and EEPROM. (The writing takes approximately 1 minute.)

After completion of data writing, power is automatically turned on.(Do not disconnect the AC

cable while data is being written.)

After replacing EEPROM, readjust and verify electrical adjustment to the service manual.
