PANASONIC - PDP 5006H PLASMA DISPLAY WITHOUT TUNER [SOFTWARE UPGRADE & CIRCUIT DESCRIPTION]



SOFTWARE UPGRADE PROCESS

  • Power switch OFF.
  • Connect the serial port of the control device to the RS-232 jack on the PDP back panel.
  • Power switch ON.  The power indicator on the front of the panel should now display 'Red' means that the PDP is in standby mode.
  • Copy the software [Flash Upgrader] to the computer.
  • Open the software [Flash Upgrader.exe]
  • Point "Flash" on the interface of the 'Flash Upgrader.exe'.
  • Press standby button on the front panel, or 'Power' button on the remote control.  Power indicator 'Green', the PDP is in power ON mode, software start upgrader immediately. 
  • Waiting for Upgrader Programming, when it is finished, the PDP will auto power ON.
  • After Upgrader is finished, shut down the Power switch, take out the RS 232C connection after the power indicator extinguished.  
  • THE COMPUTER AND PDP MUST BE KEEP 'POWER ON' IN THE SOFTWARE UPGRADE PROCESSING. 
CIRCUIT DESCRIPTION

Module: 
There are 1 pc panel and 12pc.s PCB including  2 pc.s Y/Z sustain board, 2 pc.s of 'Y' drive board, 6 pc.s of X Extension boards, 1 pc control and 1pc power board.

SET:
There are 6 pc.s PCBs including  1 pc AUX.PSU board, 1pc keypad board, 1pc remote control receiver baord, 1pc L/R Speakers and 1pc main video board in the set.

PCB FUNCTION
  1. Power:  Input voltage AC 110V to 240V, 47Hz to 63Hz.  Input range AC 90V min and 265V Max; auto regulation.  To provide power for PCB.
  2. Main video interface board:  To process S-Video signals, AV signals, Y Pb/CbPr/Cr signals, DVI signals and D-SUB signals to digital ones  and to transmit to control board.
  3. Control Board:  Dealing with the digital signal [LVDS] for output to panel.
  4. Y-Sustainer / Z-Sustainer board:  Receiving the signals from control and high-voltage supply. Output scanning waveform for module.
  5. Y Drive board:  Receive signal from Y sustainer, output horizontal scanning  waveform to the panel.
  6. X-Extension boards 6 numbers:  Output addressing signals.
  7. Audio Board:  Process and amplifying the audio signals to speakers.
PCB FAILURES
  1. Control:  Abnormal Noise on the screen, No picture.
  2. Main [Video]:  Lacking color, Bad color scale, No picture but signals output, ODS and back light, abnormal noise on the screen.
  3. Power:  No picture, No power output.  
  4. Z-Sustainer:  No picture, Color not enough, Flash on the screen.
  5. Y-Sustainer:  Darker Picture with signals.
  6. X-Extension:  Abnormal Vertical noise on screen.
  7. Audio board or AUX PSU:  No voice, Noise.
