Standard Notes

WARNING

Many electrical and mechanical parts in this chassis
have special characteristics. These characteristics
often pass unnoticed and the protection afforded by
them cannot necessarily be obtained by using
replacement components rated for higher voltage,
wattage, etc. Replacement parts that have these
special safety characteristics are identified in this
manual and its supplements; electrical components
having such features are identified by the mark “#” in
the schematic diagram and the parts list. Before
replacing any of these components, read the parts list
in this manual carefully. The use of substitute
replacement parts that do not have the same safety
characteristics as specified in the parts list may create
shock, fire, or other hazards.

Notes:

1. Do not use the part number shown on these
drawings for ordering. The correct part number is
shown in the parts list, and may be slightly
different or amended since these drawings were
prepared.

2. All resistance values are indicated in ohms
(K = 10

3. Resistor wattages are 1/4W or 1/6W unless
otherwise specified.

4. All capacitance values are indicated in µF
(P = 10

5. All voltages are DC voltages unless otherwise
specified.

LIST OF CAUTION, NOTES, AND SYMBOLS USED IN THE SCHEMATIC DIAGRAMS ON
THE FOLLOWING PAGES:

1. CAUTION:

CAUTION: FOR CONTINUED PROTECTION AGAINST RISK OF FIRE, REPLACE ONLY WITH SAME

TYPE_A,_V FUSE.

ATTENTION: UTILISER UN FUSIBLE DE RECHANGE DE MÊME TYPE DE_A,_V.

2. CAUTION:

Fixed Voltage (or Auto voltage selectable) power supply circuit is used in this unit.
If Main Fuse (F601) is blown, first check to see that all components in the power supply circuit are not
defective before you connect the AC plug to the AC power supply. Otherwise it may cause some components
in the power supply circuit to fail.

3. Note:

1. Do not use the part number shown on the drawings for ordering. The correct part number is shown in the
parts list, and may be slightly different or amended since the drawings were prepared.

2. To maintain original function and reliability of repaired units, use only original replacement parts which are
listed with their part numbers in the parts list section of the service manual.

4. Voltage indications on the schematics are as shown below:

Plug the TV power cord into a standard AC outlet.:

Distinction Area

Line Number
(1 to 3 digits)

Examples:

1. "1-D3" means that line number "1" goes to the line number
"1" of the area "D3".

2. "1-B1" means that line number "1" goes to the line number
"1" of the area "B1".

6. Test Point Information

: Indicates a test point with a jumper wire across a hole in the PCB.
: Used to indicate a test point with a component lead on foil side.
: Used to indicate a test point with no test pin.
: Used to indicate a test point with a test pin.

Voltage

Indicates that the voltage
is not consistent here.

CAUTION !

Fixed voltage (or Auto voltage selectable) power supply circuit is used in this unit.
If Main Fuse (F601) is blown , check to see that all components in the power supply
circuit are not defective before you connect the AC plug to the AC power supply.
Otherwise it may cause some components in the power supply circuit to fail.

CAUTION ! :

ATTENTION : Utiliser un fusible de rechange de même type de 4A, 125V.

For continued protection against risk of fire,
replace only with same type 4 A, 125V fuse.

NOTE:

The voltage for parts in hot circuit is measured using
hot GND as a common terminal.
