SAFETY CHECK-OUT
1. Check the area of your repair for unsoldered or poorly-sol-
dered connections. Check the entire board surface for solder
splashes and bridges.
2. Check the interboard wiring to ensure that no wires are
"pinched" or contact high-wattage resistors.
3. Look for unauthorized replacement parts, particularly tran-
sistors, that were installed during a previous repair. Point
them out to the customer and recommend their replacement.
After correcting the original service problem, perform the following
safety checks before releasing the set to the customer:
4. Look for parts which, through functioning, show obvious
signs of deterioration. Point them out to the customer and
recommend their replacement.
5. Check the B+ voltage to see it is at the values specified.
6. Flexible Circuit Board Repairing
•Keep the temperature of the soldering iron around 270˚C dur-
ing repairing.
•Do not touch the soldering iron on the same conductor of the
circuit board (within 3 times).
•Be careful not to apply force on the conductor when solder-
ing or unsoldering.

2-1-1. Equipment Required
The measuring instruments used for this alignment include:
1) Monitor TV
2) Oscilloscope, dual-trace, bandwidth of 30 MHz or more, with
delay mode (A probe 10:1 should be used unless otherwise
specified.)
3) Frequency counter
4) PAL Pattern generator
5) Remote commander
6) Digital voltmeter
7) Audio generator
8) Audio level meter
9) Audio attenuator

2-1-2. Equipment Connection
Unless otherwise specified, connect and adjust the measuring in-
struments as shown in the following diagram.
Fig. 7-2-1
2-1-3. Set-up of Adjustment
In this adjustment, PAL pattern generator is connected with LINE-
2 input terminal. When check to tuner, connectedAERIAL termi-
nal. Check that the synchronizing signal of the Y signal has an
amplitude of approximately 0.7V and that the burst signal has an
amplitude of approximately 0.3 V and its waveform is flat. And
check that the level ratio of burst signal to “red” signal is 0.30 :
0.66. The video signal (color bar) used for electrical aligning this
unit is shown in Fig. 6-2-2.
