following:
*
200 channels in memory
*
Image processing includes brightness control, contrast control, control color,
system color control, image enhancement and five image modes.
*
Users can edit the LOGO, show the LOGO when starting up and without signal
*
Have the perpetual calendar and the game function.
*
New OSD style, compatible with English, Thai, Vietnamese, Indonesian, Persian, Turkish,
French, Bulgarian, Russian, Portuguese, Roman, Spanish, Italian, German, Dutch,

Remote
control of the NEC code, press the [PRESET] key first, then press the [TEST]
key within 2 second.
The TV enters production mode and the screen shows the
production mode indicator.
Remote
control of the SANYO code, press the [TEST] button.
The TV enters production
mode, display screen, show tips for the mode of production.
Press
[TEST] or [POWER] to switch from production mode to status normal work.
Press
[- / - -] in the [PROOF] state to enter the [BUS OPEN] state.
Under
[BUS OPEN], press the [- / - -] key to return to the factory state.
Enter the debug / configure menu method
* User
debugging menu: press the [TEST] or [MENU] key plus the numeric key "6, 4,
8, 3", enter the white balance debug state " B / W BALANCE "and
then press [TEST] or [Display] to enter the "M0" menu, then press the

In the "M0" ~ "M9" state, press the [Display] button to
enter "FACTORY" mode.
Description of the debugging project of the menu: Factory.
Image debugging menu, take the PHILIPS / PAL test card (or
select the built-in verifier signal).
*V.SLOPE
adjustment so that the horizontal centerline of the test card is in the upper
part of the piece.
*
Adjust V.POSI so that the vertical center of the image is consistent with the vertical
center of the CRT
*
Adjust V.SIZE so that the vertical amplitude of the image complies with the requirement,
and the re-emphasis rate = 90%
*
Adjust VSC to make the vertical correction of the best image S
*
Adjust H.PHASE so that the horizontal center of the image is consistent with the
horizontal center of the CRT
H.BLK.L (0 ~ 15), you can adjust the line
erase position to the left
H.BLK.R (0 ~ 15), you can adjust the line
cutting position on the right side
*
Take the PHILIPS test card (NTSC) and adjust the 60 Hz value to the base original
50 Hz. On the basis of increase or decrease.
Adjust
the white balance (after the values recommended in the table)
*in
"TEST.S" select the signal with the remote control.
*
Then select the item "VSD", press the "V +" button to enter
the state of the horizontal line.
*
The numeric key "2" reduces "R.BIA", the numeric key
"3" increases "R.BIA"
*
The numeric key "4" reduces "G.BIA", the numeric key
"5" increases "G.BIA"
*
The number key "6" reduces "B.BIA", the number key
"7" increases "B.BIA"
*
When adjusting to white, adjust potentiometer G2 on the FBT so that on the screen
appears one line horizontally, then press the "V +" button to return
to full screen status
*
Set the values of "R.DRV, G.DRV, B.DRV" until it reaches the desired

(high or low voltage). The noise in the image is gradually reduced until the
noise simply disappears. At that moment, the tension of the point of TP-AGC
test, and the voltage is the desired AGC voltage. This tension is the tension of
AGC adjustment of the machine in the future.
