SCHEMATIC DIAGRAMS / CBA'S AND TEST POINTS

Standard Notes
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.
Note of Capacitors:
ML --- Mylar Cap. PP --- Metallized Film Cap. SC --- Semiconductor Cap. L --- Low Leakage type
Temperature Characteristics of Capacitors are noted with the following:
B --- ±10% CH --- 0±60 ppm/°C CSL --- +350~-1000 ppm/°C

µF).
Tolerance of Capacitors are noted with the following:
Z --- +80~-20%
Note of Resistors:
CEM --- Cement Res. MTL --- Metal Res. F --- Fuse Res.
Capacitors and transistors are represented by the following symbols.

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.:

5. How to read converged lines
1-D3 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.

Because a hot chassis ground is present in the power supply circuit, an isolation transformer must be used. Also, in order to have the ability to increase the input slowly,when troubleshooting this type power supply circuit, a variable isolation transformer is required.
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.
4A/125V
CAUTION ! :
ATTENTION : Utiliser un fusible de rechange de même type de 4A, 125V.
NOTE:
The voltage for parts in hot circuit is measured using hot GND as a common terminal.
For continued protection against risk of fire, replace only with same type 4 A, 125V fuse.
