: nonflammable resistor.
•
: fusible resistor.
•
¢
: internal component.
•
: panel designation or adjustment for repair.
•
All variable and adjustable resistors have characteristic curve
B unless otherwise noted.
•
Readings are taken with a color-bar signal input.

•
Voltage are dc with respect to ground unless otherwise
noted.
•
Voltage variations may be noted due to normal production
tolerances.
•
All voltage are in Volt.

Note: The reference number which starts with Wxxx
(eg: W003) indicates a wire to wire connection.
Note: Components marked as XX are not fitted on this
model.

Note: "A" board schematic diagram is divided into 3
blocks. Each block is named by its function and
block "number". eg: Processor/Audio/Tuner/Jack
(Block 001).
Joint connection between boards can be identified
using the block number followed by the grid's guide.
eg:-
<
+B
002:16F
Meaning: Block 001 joint "+B" is connected to Block
002 joint "+B" located at grid 16F.
