[Measuring conditions, voltage and waveform]
..
..
. A voltage value is the reference value between the measurement
point and the earth, when the color bar signal is received from the
color bar generator. (digital multi-meter used: 10 M ohms/V DC)
..
..
. Unit of voltage is V (volt).
(Voltage variations may occur due to normal production tolerances.)
..
..
. : B line
..
..
. No mark : Color bar signal.
..
..
. Circled numbers indicate the reference waveform.
..
..
. : Signal path.

. Caution when replacing chip parts
New parts must be attached after removal of the chip.
Be careful not to heat the minus side of a tantalum capacitor,
because it is easily damaged by the heat.
