			Notes on repairing flat CRT TV set		REF.No.		:G − 99 − 076 − E0
						DATE	:02. MAR. 2000

<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 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:

	Model name	R848	Type
	TV−F21ST1	33Ω/2W	cement resistor
	TV−F25ST1	27Ω/2W	cement resistor
	TV−F2400
	TV−F2000	56Ω/2W	cement resistor

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.

<CONTENTS>

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.

Note :The cement− resistor is not installed, if the serial number of unit is not included in table above.

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

			The screen is too dark			REF.No.	:G − A0 − 032 − E0
						DATE	:31. MAY. 2000

<CONTENTS>

The screen voltage falls down due to an abnormality of the capacitor C901 thereby causing the screen to become dark.

Take the following countermeasure when this problem is pointed out.

<COUNTERMEASURE> Replace the capacitor C901.

Always make sure to use the specified part because the manufacturer of this part has been changed.

						DATE	:05. JUN. 2000

<CONTENTS>

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.

<COUNTERMEASURE>

Please replace the component with the one specified below.Take care about the differences between the regional models.

<CONTENTS>

For betterment of the "step by step instructions" on the SET UP procedure in the Service Manuals, we add one more step as described below.

Correction(add the red colored sentence)

Step "No.3" shown in red to be incerted to the procedure.

1.Use the numeric keys on the remote control to set the receiving channel to Pr91.

2.Set Sharpness on the Picture Menu screen to 0.

3.Press MENU button on the remote control twice to back to the normal mode. (Channel Pr91 appears on the screen).

4.Press the buttons on remote control in the following order:

Skip(R) Move(G) Menu

The following menu will appear on the TV screen (the menu can be seiched by the " P / " button on the remote control).

5.To terminate the menu screen, press the MENU button on the remote control,or the power button on the TV or remote control.

<NOTE>

Pressing three button described in the process 4 above must be done with a second, or it will not get into the Service Mode.
