TO ENTER SERVICE MODE

  • Push [“UP” => “MUTE” => “DISPLAY” => “MUTE”]  BUTTON of Remote Controller to enter SERVICE adjustment MODE.
DESCRIPTION OF SERVICE MODE ITEMS

PW171:
  •  It is a Image processor and used to adjust White balance.
  • [Note] This article is for adjustment after replacement of VIDEO PCB. These values may vary from set to set. Therefore if these values are recorded before replacing VIDEO PCB, you do not need to adjust WHITE BALANCE additionally. The setup can be done using the recorded values.
  1. SUB BRT : For BRIGHTNESS adjustment (fixed)
  2. SUB CONT : For CONTRAST adjustment (fixed)
  3. BIAS R : For R BIAS adjustment (Changeable)
  4. BIAS G : For G BIAS adjustment (Changeable)
  5. BIAS B : For B BIAS adjustment (fixed)
  6. GAIN R : For R GAIN adjustment (Changeable)
  7. GAIN G : For G GAIN adjustment (Changeable)
  8. GAIN B : For B GAIN adjustment (fixed).
SAA7118
  • It is a VIDEO DECODER and used to adjust a picture quality for VIDEO/DVD(480i).
  • [Note] This article is not for adjustment after replacement of VIDEO PCB. Therefore do not change initial values.
  1. SUB BRT : For BRIGHTNESS adjustment (VIDEO/DVD) (fixed)
  2. SUB CONT : For CONTRAST adjustment (VIDEO/DVD) (fixed)
  3. SUB CLR : For COLOR adjustment (VIDEO) (fixed)
  4. SUB TNT : For TINT adjustment (VIDEO) (fixed)
  5. SUB SRP : For SHARPNESS adjustment (VIDEO) (fixed).
DPTV:
  • Be used to adjust DEINTERLACE performance.
  • [Note] This article is not for adjustment after replacement of VIDEO PCB. Therefore do not change initial values.

  1. SUB BRT : For BRIGHTNESS adjustment (VIDEO/DVD) (fixed)
  2. SUB CONT : For CONTRAST adjustment (VIDEO/DVD) (fixed).
CXA3516:
  • It is a DTV/PC PROCESSOR and used to adjust a picture quality for DTV/PC.
  • [Note] This article is not for adjustment after replacement of VIDEO PCB. Therefore do not change initial values.

  1. SUB CONT : For CONTRAST adjustment (fixed)
  2. Cb OFFSET : For Cb Offset adjustment (fixed)
  3. Cr OFFSET : For Cr Offset adjustment (fixed)
  4. HYS : For Sync hysteresis adjustment (fixed)
  5. THR SLP : For Sync threshold adjustment (fixed).
MSP34X0This article is not for adjustment after replacement of VIDEO PCB. Therefore do not change initial values.

PRESCALE: Be used to adjust a Audio prescale

MISC TSTPTRN AT:
  • Cycled patterns from R à G à B WH every 1 minute automatically.
  • TST PTRN MA : Cycled patterns from BK à WH à R à G à B by pressing volume up key.
  • AT PWR : ON - Condition where turning AC power on, automatically turns the SET on.
  •   OFF - Condition where turning AC power on makes the Set STAND BY, and POWER of Remote-controller on turns the set on from STAND BY state.
JACK:  
  • Set up depending on input MODE of JACK BOARD.
  1. SCART(Normal) : MULTI + DVI + SCART (DSP-4222LVS, DSP-5012LXS)
  2. MULTI : Used by DSP-4280 series, Multimedia monitor.
  3. MONITOR : Used by DSP-4282 series, PC only monitor.
  4. MONITOR+ : Used by DSP-4282 series with DSP-JU20 attached, PC only monitor with External board connection.
  5. DVI : MULTI + DVI, Used by DSP-4284 series, DSP-4220/4224LVS and DSP-5010/5014LXS - VIDEO : Video only monitor.
  6. [Note] Wrong setup causes displaying problem. So you must be careful when SETTING.
PXL SET:
  1. ON - Moving screen up, down left and right by some Pixels every 20 seconds.
  2. OFF - Fixing PIXEL position. No movement on screen.


  • [Note] PIXEL SHIFT function is solution to characteristic phenomenon of PDP, so-called “Image Sticking” problem. Leave this function ON, when displaying many fixed screen like PC screen. When this function is ON the screen will move a little for every fixed interval but a human eye can not recognize it well.
INFOR
MICOM VERSION.  (year 4 digits, month 2 digits, date 2 digits and time 4 digits : 200309222030 )

RESET.
EDID SET
  • [Note] Be used to set to write EDID data (After setting it is changed to “EDID DONE”). Before setting EDID, you have to short jumpers of JP710. After setting, you must remove jumpers, and then, turn off and on main power. If “EDID WRITING ERROR” is displayed, Try again. But, in DEUK, you don’t have to set EDID set (After removing jumpers, EDID DONE is changed to EDID SET).

  1. LEVEL 1 : Be used to initialize all of the data including adjusted figures for W/B.
  2. LEVEL 2 : Be used to initialize all of the data except adjusted figures for W/B
  3. FACTORY : For User menu initialization, is actaviated by choosing a language on AC ON mode. (Menu Display, VOL, OSD Background and Input mode (VIDEO 1) initialization).
PANEL

ISM
  • Used to minimize Image Sticking (ON/OFF).
  • ON : When Still images or regular patterns have been displayed on screen for some times, the luminance of screen is going to decrease as below. (But, only when pattern area is over 50% and it is lasting over 5 minutes).


BWINV:
  • Used to minimize Image Sticking (ON/OFF).
  • ON : Inverting the original images.(in Digital image data, “0” à “1”, “1” à “0”).  If Still images have been displayed for some periods, this function can minimize Image sticking, by displaying it on BWINV mode for some times.
GAMMA:
  • Can choose one in 4 gamma tables.

  1. BRIGHT : Adjusting Peak Luminance
  2. 100% : Full Peak Luminance
  3. 63% : 63% of Peak luminance
  4. 40% : 40% of Peak luminance
  5. APL: Average Picture Level
SCROLL:
  • Minimizing Image Sticking (ON/OFF) by Shifting whole screen BRIGHT
  • Adjusting Peak Luminance. (same with PXL SFT function in 6)MISC) ON : This function moves1~8 pixel with a regular rule, up, down, left, right every 10 sec.
BRIGHT:  Adjusting Peak Luminance.

P SAVE:
  • Controlling power consumption by changing Luminance level of whole screen.

  1. 100% : Peak Luminance & Maximum Power Consumption mode
  2. 87% : 87% mode
  3. 75% : 75% mode
  4. 50% : 50% mode
linear : linear mode(Constant luminance without regard to APL)
# WARNING!! The choice of these modes can cause difference of Power Consumption.

  • MOVING:  Setting display mode of Input channel except PC input.
  • STILLSetting display mode for PC input.
