INSTALLATION AND SERVICE ADJUSTMENTS
GENERAL
In the majority of cases, a color television receiver will need only slight touch-up adjustment upon
installation. Check the basic characteristics such as FS、EHV and focus. Observe the picture for
good black and white details without objectionable color shading. If color shading is evident,
demagnetize the receiver.
If color shading still persists, perform purity and c onvergence adjustments. This should be all that is
necessary to achieve optimum receiver performance.
FOCUS ADJUSTMENT
Adjust the FOCUS control (on T471) for well defined scanning lines on the picture screen.
HIGH VOLTAGE CHECK
CAUTION: These is no HIGH VOLTAGE ADJUSTMENT on this chassis. Checking should be
done following the steps below.
1. Connect an accurate high voltage meter to the second anode of the picture tube.
2. Turn on the receiver. Set the BRIGHTNESS and CONTRAST controls to minimum (zero beam
current).
3. High voltage will be measured below 24kV.
4. Vary the BRIGHTNESS control to both extremes to be sure the high voltage does not exceed the
limit under any conditions.
FS CIRCUIT CHECK
The Fail Safe (FS) circuit check is indispensable for the final check in the servicing. Checking
should be done following the steps below.
- 3 -
1. Turn the power switch on and adjust customer controls for normal operation.
Check that the set returns to normal operation when pin
34 of N101 on the Main Board is grounded with jumper
Power Circuit or Horizontal Circuit
Check if the voltage across capacitor
C411 is approximately 21V.
2. Temporarily short R412 on the Main Board with a jumper wire. Raster and sound will
disappear.
3. The receiver must remain in this state even after removing the jumper wire. This is the evidence
that the FS circuit is functioning properly.
4. To obtain a picture again, temporarily turn the receiver off and allow the FS circuit more than 30
seconds to reset. Then turn the power switch on to produce a normal picture.

PIF alignment
1) Apply DC 12V to output pin of N551(pin3 of N551 ) , connect pin7 of LA76814(N101)
to GND.
2) Apply 95dBμ, 45.75MHz RF signal to the tuner's IF pin through a 1000P ceramic
capacitor. Connect the DC voltameter's⊕pole to LA76814 pin 47 , ⊙ pole to GND.
Note: For LA76814 ES01 version, the voltameter's⊕pole should connect to pin50 .
3) Adjust T202 with a non-inductive screwdriver until the reading on the DC voltameter is DC
3.6V±0.01V.
B+ CHECK
1) Prepare the test equipment.
2) Use the DC voltameter at DC 200V position to test VD551⊕, i.e. B+.
3) Connect the power plug to AC 120V/60Hz, turn on the power switch, wait for normal raster,
then adjust RP551 to make B+ = 110V±0.5V.

TEST MODE SET(CHECK)
TEST MODE ADJUSTMENT INSTRUCTION
TEST MODE adjustment is a special adjustment which is controlled by I2C BUS. The TV set has
been set at optimum mode at the factory. Except for special need, such as replacing CRT
MEMORY IC etc., it is hoped not to adjust it.

H-center adjustment, V-amplitude, linearity, S-correction, V-center adjustment
1) Press the GEO button on the remote controller to enter into the ADJUST mode.
2) Select the H.PHASE item, adjust the level to make the left and right picture sysmmetrical.
3) Select the V.POS item , adjust the value to make V-center and the CRT's geometric center is in
accordance. Then select the V.SIZE item, adjust the value to make the overscan is less than or
Equate 10% .
4) Select the V.LINE item, adjust the value to make the upper and lower grid's(on the screen)
vertical distance equal. Select the V.SC item, adjustthe value to make the vertical distance from
upper grid to middle screen is equal to the vertical distance from lower grid to middle screen.
5) Press the PICTURE button on the remote controller to save the data.
White balance
1) Press the W/B button on the remote controller to enter into the ADJUST mode.
2) Set the value of item as the following table:
