ADJUSTING PROCEDURE OF EACH SECTION
The best adjustment is made before shipping. If any position deviation is found or after part replace is performed,
adjust as follows.
Preparation for adjustments
Use the dedicated AC adaptor or stable DC power supply.
AC adaptor: UADP-A007WJPZ
DC power supply: 12V 4.0A
1. Adjusting procedure
• Checker adjustment
Power ON (Adjustment processing mode) 
→ 
+B adjustment 
 Counter bias adjustment 
→ 
TAMP (Contrast)
adjustment
→ 
White balance adjustment
2. Entering the adjustment processing mode
There are the following two methods.
• Setting the pin (81)(KEY4) or pin (82)(KEY5) of IC2001 (microprocessor) to GND, turn on the power.
• A “POWER” key is made on with pushing an “TV/VIDEO” and “MENU” keys at the same time.(K of the inspection
process mode is displayed by the upper left of the image plane.) 
 Next, “CH (
Ù
)” and “VOL (–)” keys are pushed
at the same time.(It becomes the image plane of the adjustment process mode.).....When it is canceled, it is made
to turn it off.(Even off in the “MAIN POWER” key, off with R/C are good.)
3. Key operation in the adjustment process mode
• The receiving channel UP/DOWN is performed with the “CH (
ù
)/(
Ù
)” keys.
One push ... The UP/DOWN tuning is performed per channel.
Continuous push ... The UP/DOWN search is performed until a next receivable station is found.
• Various adjustments
The adjustment is performed for each item by the “MENU”, “Menu cursor”, “CH (
ù
)/(
Ù
)” or “VOL (+)/(–)” keys
(LCD TV set and remote control).
• Adjustment item is chosen with the Menu cursor upward/downward keys.
• The adjustment item makes a toggle operation with the “MENU” key input. (Next item)
If the “MENU” key is input while the bottom item is selected, it moves to the top item on the next page.
• Press the auto preset button on the remote controller in the adjustment process mode, and the top item of the
next page will show up regardless of which item appears now.

• Press the manual memory button on the remote controller in the adjustment process mode, and the top item of
the same page will show up.
• UP/DOWN of each adjustment vale selected is performed with the VOL (+)/(–) keys input.
• For P16 – 17, the unit enters the register select mode with the VOL (+)/(–) keys input while NTSC/PAL is selected,
and the cursor moves to the address 01.
• The cursor moves up or down with the “CH (
ù
)/(
Ù
)” keys and moves left or right with the VOL (+)/(–) keys, and a
decision is made with the 12 key.
When the decision is made, the cursor moves to the adjustment value selected, and UP/DOWN of each adjustment
value selected by the “VOL (+)/(–)” keys input is performed.

5. Adjustment
5-1. +B adjustment...Page 1 +B-ADJ
Adjust the voltage of the pin (13) of P2002 to 5.00 ±0.02V.
Note: Since 5.0V is a reference voltage of all power voltage, adjust it precisely.
5-2. Counter-bias adjustment
Vary the "COM BIAS" setting on Page 2 of the adjustment process mode so that the contrast be sharpest
(black looks most sinking).
5-3. TAMP adjustment
1) Receive the upper left of 75% white half colour bar signal.
2) See if the “Y” reading on page 2 of the adjusment process mode is somewhere following. If not, make the
“PAL TAMP” adjustment to get the “Y” reading in the range of BF thru C9.
3) If the adjustment of “PAL TAMP” is executed, write its adjustment value to the “SECAM TAMP” manually.
(Screen of the page 2 of the adjustment processing menu OSD)
5-4. White balance adjustment
Adjust “RCUTOFF” and “BCUTOFF” on the page 2 of the adjustment processing so as to obtain the colour
of the same level as the standard set.
Note: For the adjustment processing of “RCUTOFF” and “BCUTOFF”, adjust them in the indication value
range of ... –9, –7, ... –1, +1, ... +7, +9.
When it becomes even-numbered value, side favor noise sometimes occurs in the monochrome signal of
the specific gradation.
