TEST MODE
1. Setup Method
Reset by pressing the 'VOL UP' key and 'SCRN" key.
2. Details
Includes all items applicable to the supported NA-R300 remote control unit.
3. Termination Method
Reset terminates test mode, and sets all values to initialization values
(except for data adjusted with the test mode touch adjust etc.)

Beep
TV Tuner
The dimmer responds with the same timing (without waiting) as external light changes
Following power on, the video source is TV (VIDEO1 for the W market sector)
The video source can be changed with the remote control BAND key.
The AVIN1 and 2 settings are for VIDEO.
Full
The touch adjust screen is recalled with the remote control SRC key.
The SET UP screen touch adjust allows the touch panel reference points (2 points)
to be written to E2PROM. Proper completion of writing to the E2PROM is followed by
two beeps. The occurrence of an error results in four beeps. The data remains even
if test mode is reentered.
During touch response a + cursor is displayed for both NTSC and full screen.
When navi supporting wide mode is connected, the navi screen displays the navi
transmission X, Y coordinates in numerals.
The remote control MODE key allows ON/OFF switching (normally ON).
One click allows cycling between Full Down ↔ Center ↔ Full Up
Irrespective of video source, set the contrast curve in the range 0.0~2.5~5.0[V]
For even overseas models a single press causes a beep (Same as J).
Seek mode is AUTO1
Following power on displays 9CH (J), 11CH (K/H), 9CH (M:CHINA).
Updates TV1 preset channels with dedicated test mode initialization values.
The remote control VOL UP key recalls the TV AREA setup screen.
The remote control VOL DOWN key changes the TV AREA.
The remote control ten key pad allows recall of preset CH (same as normal operation).
The remote control TV/NAVI key allows diversity adjustment mode On/Off.

LZ-800W ADJUSTMENT
1. Screen display start
position confirmation
2. Flicker adjustment
3. Flicker confirmation
• Monoscope
• Input signal
Composite input
Grey RASTA
(white 30~50%)
• ZOOM mode
• Set to AC range
• Flicker jig
• With a monoscope display confirm that the left and right positions are equal.
If they are slightly off, adjust for left/right equality with VR200.
If there is a big discrepancy, redo from the X35 adjustment.
• Adjust VR302 to minimize flicker (60Hz component)
• Confirm there is no flickering when setting to ZOOM or CINEMA mode
Item Adjustment method/Adjustment value Conditions
X35 Unit Adjustment Specification
1. V-LEVEL adjustment
VR401 • Input selector = AV1 Output selector = TV
• AC range
• When adjusting with the X25
unit alone, terminate pin 6 with
75Ω
1. Feed a stair step (or ramp) signal into the Video in 1 terminal.
2. Observe pin 6 [GREEN] of CN4 with an oscilloscope and adjust
VR401[V-LEVEL] so that the difference between the pedestal
and white level is as shown below.

• Set to AC range
• Oscilloscope 0.5V/DIV
• Pressing the (SCREEN) and (VOL+) keys set the (RESET) key ON.
• Set to VIDEO mode.
• Using VR201 set the HYS frequency when no input is present to
15.734kHz±0.01kHz.
• With a monoscope adjust for left/right equality with VR200.
Alternatively, adjust VR200 so that the phase difference between the fall
of HSY from the timing controller IC and SYNC rise is about 2.1µSec.
• Feed composite SYNC (10 step signal) into the SYNC input.
(1) Adjust RGB AMP VR301 so the SYNC-SYNC interval is 4.0±0.1Vp-p.
(2) Adjust VR306, 305 and 304 so GAMMA0, GAMMA2 and CONTRAST
are 3.5V±0.1V.
(3) Adjust BLACK adjustment VR300 so the 4th step from the pedestal is
3.0V±0.1V.
(4) Adjust GAMMA0 VR306 so the 3rd step from the pedestal is 1.0V±0.1V.
(5) Adjust BLACK adjustment VR300 so the 4th step from the pedestal is
2.0V±0.1V.
CAUTION: There are two points where 2V can be obtained, but please
ensure you turn VR300 to the right.If you obtain 2V by turning VR300
to the left, you will not be able to perform adjustment (6).
