37 Simplified Block Diagram 03 Professional Models Roughly speaking, the unit consists of three signal circuit blocks:. Input Source 2. Video and Audio Signal Processor with speaker output 3. Panel Drive The unit contains a permanent PC input and three card slots that can be used for different types of input signals. The signals may be in the NTSC, ATSC, DVI, HDMI, or SD format. After selection, the video signal is provided to the video signal process block of the unit. The video process circuit converts the video signal from analog to digital and performs picture control operations such as brightness, contrast, sharpness, color, tint, etc. The output signal of the board passes through an LVDS (Low Voltage Differential Signaling) transmitter for conversion into serial data. The panel drive block is responsible for displaying the picture on the screen. It provides the scan, sustain and data drive signals to the panel. Sound inputs to the unit are also selected in the input source block and provided to the sound process block. There, the sound undergoes sound control operations such as bass, treble, balance and volume before being output to the speaker terminals. 37

39 Picture signal flow 03 Professional Models Slot or Slot 2 may be used for component or DVI inputs. The drawing shows both connections for better understanding of the video selection and process of this unit. The DS board is an input board that contains 3 slot terminals. The Slot terminals may be used in conjunction with boards that facilitate NTSC, ATSC, RGB, DVI, and SD video input. Component, RGB or PC Video are input to the DS board and selected by IC3005. The selected input is provided to the DN board for conversion into 0 bit parallel data and input to the Video Processor IC, IC50. If slot or 2 is used for DVI input, the LVDS data from the input board passes through the DS board without alteration and enter the DN board. On the DN board IC500 and IC5002 converts the LVDS data into YUV data for application into IC50, the Video Processor. IC50 performs input selection and picture control operations such as brightness, contrast, sharpness, color, tint, etc. It is also responsible for PIP (picture-in-picture) and IP conversion of the video signal. IC50 also combines the OSD (On- Screen Display) signal from the system control Microprocessor with the main digital video signal. The RGB output signal of the DS board passes through a LVDS (Low Voltage Differential Signaling) transmitter for conversion into serial data. IC9500 PLASMA AI (LSI27) The LVDS receiver inside IC9500 of the D board converts the video signal to 0 bit RGB data, its original format. The 0 bit data is memorized into two field data to drive the left and right side of the panel. The outputs are provided to the Subfield data circuits, IC9400 and IC9300. IC9300 and IC9400 Subfield converter IC9400 and IC9300 are used to drive the left and right half of the panel. They each contain a format converter that changes the resolution of the video signal to match the size of the panel. They also contain the Plasma AI (Adaptive brightness Intensifier) circuits that analyze the APL* for the distribution of dark and bright components. They subsequently convert the picture data into 0,, or 2 subfields data to feed the data electrode of the panel. IC9003 CPU IC9003 is the CPU that controls the operation of the circuits that drive the panel. It also generates the OSD data (pattern) that is used to troubleshoot the panel s drive circuits.

41 Panel Drive (Basic Circuit) Discharge Control 03 Professional Models IC9500 of the D board contains the Discharge Control circuit that analyzes the RGB and sync information of the video signal to create the Scan data to drive the Scan operation (SC) board and Sustain data to drive the Sustain operation (SS) board. The SC board is responsible for the generation of the scan pulses. Scan pulses are used for initialization and selection of the pixels. The SU, SM, and SD boards are de-multiplexer boards that are responsible for converting the serial data output of the SC board into parallel data to drive the panel. Each board drives one third of the panel horizontally. The SS board is responsible for the generation of the sustain pulses. Sustain pulses are used to initialize and control the brightness of the panel. The SS2 and SS3 boards are extension (connector) boards that connect the SS board to the panel. Data Drive The LVDS receiver inside IC9500 of the D board converts the video signal to 0 bit RGB data, its original format. the 0 bit data is memorized into two field data to drive the left and right side of the panel. The outputs are provided to the Subfield data circuits. IC9300 and IC9400 drive the left and right half of the panel. They each contain a format converter that changes the resolution of the signal to match the size of the panel. They also contain the Plasma AI (Adaptive brightness Intensifier) circuits that analyze the APL* for the distribution of dark and bright components. They subsequently convert the picture data into the 0,, or 2 subfields data to feed the data electrode of the panel. The data drive signals of IC9300 and IC9400 are output to the CD boards. All six CD boards are exactly the same and have the same part number. The CD boards are buffer boards that are used to distribute data to the 2 C boards. There are three CD boards that provide data to the C-C6 boards. The C-C6 boards buffer the data drive signals that are applied to the upper half of the panel. There are three other CD boards that provide data to the C7-CZ boards. The C7-CZ boards buffer the data drive signals that are applied to the lower half of the panel. APL = Average Picture Level 4

51 Picture Trouble () 03 Professional Models This page covers the type of distortion one might notice in the picture. It is very easy to determine that a black bar on the screen is a panel drive problem. When we experience a color problem, it becomes somewhat difficult to determine whether the problem is due to a defect in the panel drive circuits or video processing circuit (DN board). To troubleshoot a signal problem such as distortion in the picture, disconnect the connector D5 from the D board. A white raster appears automatically.. If the white raster does not appear or the raster is colorful (Ie. magenta in appearance), the D board is defective. 2. If the white raster is normal, the DN board is defective. 5

63 Power supply circuit (VDA and Low Voltages) 03 Professional Models The basic operation of the new P board is the same as that of the older Plasma Display Monitors. The Standby circuit supplies STB5V for system control operation and 5V for Panel operation. The main circuit supplies Vda voltage for data drive, 5V for sustain, scan, and fan operations. The F_STB_5V is used on the DS board to generate other operating voltages for the the video processing circuit. 63

64 Power supply circuit (VSUS) 03 Professional Models F LINE FILTER P P9 4 AC IN Line Filter Rectification Power Factor Control 395V Vsus 85V Due to the amount of current required to drive this plasma display panel, a separate circuit is used to generate the VSUS voltage. Its basic operation is the same as previously used power supplies. The incoming AC voltage is filtered and rectified. The DC voltage is applied to a power factor control circuit to improve the power ratio. The output is then applied to a switch mode power supply for the generation of the VSUS voltage. There are two VSUS power supplies, one on the P BOARD SS SIDE and the other on the P BOARD SC SIDE. 64

65 Line Filter 03 Professional Models The F board of the older Plasma Display Monitors is reintroduced in this model. The function of the line filter is to block incoming noise from the AC outlet to the unit and outgoing noise from the unit to the AC outlet. It provides two outputs that are connected to two separate but identical power supply boards. One of the power supply boards (P SC SIDE) is used to power the scan drive circuits and the other (P SS Side) the sustain drive circuit. 65

67 Power supply Circuit 03 Professional Models This is a diagram of the two power supply boards incorporated in this unit. One is primarily used by the SC board for scan operation and the other by the SS board for sustain operation. The AC voltage that enters the two power supply boards are filtered by the F board (not shown in the diagram). The main power switch path is routed through the SC2 board to the S board. Power ON operation via the main Power Switch P board SC After plug in, the standby power circuit begins to work immediately to produce the STB 5V source. Upon activation of the main power switch, MC70 allows the output of the STB 5V to the PC, D and DN boards. The STB 5V is regulated to 3.3V to power and reset the microprocessor of the D and DN boards. IC470 and IC9003 output the STB_ON and MAIN ON commands (approximately 2.5V) to MC70. MC70 outputs the power ON command to IC20 and IC202 to generate the Vsus voltage. The VSUS voltage is used for scan and sustain operation. MC70 also outputs the power ON command to IC502 and IC30 to generate the Vda, 5V, and STB 5V supplies. The Vda voltage is used to power the shift register ICs that are connected to the data electrodes of the panels. The VDA voltage is also used by the DR boards for energy recovery operation. The 5V output is primarily used by the D, SC, and SS boards. P board SS Operation of the P board (SS side) is exactly the same as the P board (SC side). PC board The PC board is a logic board that is used as an extension of the system control circuits to trigger and monitor the operation of the power supply boards. During standby operation, the F STB_ON command is only provided to the P SC Side power supply. The P SC SIDE power supply continues to output the F_ STB_5V to the DS board. When the unit is turned on, the MAIN_ON command goes to the P SC SIDE power supply to turn it on. At the same time a logic circuit on the PC board converts the MAIN_ON command into both, STB_ON and MAIN_ON to turn on the P SS Board Power supply. The PC BOARD also contains an OR gate that monitors the SOS outputs of the two power supplies to provide one output to the MPU IC9003. Go to page 67 to see the block diagram of the PC board. 67

At this time power on/off operation is possible via the remote control. During standby operation, the F STB_ON command is only provided to the P SC Side power supply. The P SC SIDE power supply continues to output the F_ STB_5V to the DS board to keep the unit in the standby mode. When the unit is turned on, the MAIN_ON command goes to the P SC SIDE power supply to turn it on. At the same time a logic circuit on the PC board converts the MAIN_ON command into both, STB_ON and MAIN_ON to turn on the P SS Board Power supply. 68

72 P Board Circuit (Standby Operation ) 03 Professional Models This a block diagram of the power supply circuit incorporated in this unit. Standby Power Supply The incoming AC from connector P5 is converted to DC by the rectifier D50. The DC from D50 is applied to the standby circuit (T50, IC50 and MC60) where three STB5V supplies are developed. The STB5V is applied to the Power Control Module MC202 (Not shown in the diagram, It is used for VSUS). The second STB5V is applied to the Power control IC MC70 and the third to the STB Power Control IC MC60 (Use hot ground to measure voltage on MC60). When the main power switch is activated, the standby 5Vdc is applied to pin 5 of MC70. Subsequently pin of MC70 goes low to turn on Q55 and allow the STB5V to output at pin 0 of connector P25. 72

74 P Board Circuit (Standby Operation 2) 03 Professional Models Standby Power Supply The STB5V out put at pin 0 of connector P25 is regulated to 3.3V and applied to the DN board MPU, IC470. Pin of IC470 outputs 2.5V (Tuner SUB_ON) to the P board via pin 29 of the connectors DN2/D3 and pin 3 of the connector D25/P25. It is then connected to pin 0 (F. STB ON) of the Power Control IC, MC70. The power control IC, MC70 outputs the PFC ON command to the PFC Control Module MC502 and the PFC MODULE MC703 via the Photo-coupler PC506. MC502 outputs the Relay ON command to activate the relays K70 and K703. The diode D703 rectifies the 20VAC from the relay and outputs to the PFC MODULE MC703. The PFC Module MC703 converts the DC voltage from the rectifier to 395Vdc to improve the power ratio. 74

78 P Board Circuit (Main Voltages) 03 Professional Models When the unit is turned on, the MAIN_ON command (3.2V) of the D board Microprocessor enters pin 8 of MC70 via pin 7 of connector P25. As a result, Pin 6 of MC70 switches from 5V to.3v, and pin 9 from a low to a high. The.3V at pin causes Q353 and Q35 to turn on and output 5Vdc. The 5V source is primarily used by the D, SC, and SS boards. The high at pin 9 of MC70 causes Q552 to turn on and output 5Vdc. The 5V source is connected to every board involved with panel drive operation. The Power Control Module MC40 also receives a trigger (not shown in the diagram) from MC70 to output the Vda voltage. The Vda voltage is used to power the shift register ICs that are connected to the data electrodes of the panels. Prior to entering the panel, it passes through the DR boards for energy recovery operation. 78

80 P Board Circuit (VSUS) 03 Professional Models The input voltages in this drawing originate at the standby power supply. The commands that trigger the operation of this circuit originate at MC70. One of the STB5V generated by the standby power supply enters pin 2 of the Power Control Module MC202 via pin of connector P53. Another STB5V generated by the same standby power supply enters pin 5 of connector P56. When the monitor is turned on, the PFC_ON command turns on the transistor Q25 to output the STB5V to PC202. Consequently, PC202 turns on to provide a low to pin 2 of MC202. The HV SUS_ON command enters pin 7 of connector P55/P56 to turn on the photo-coupler PC20. The high at pin of MC202 passes through PC20 to turn on MC20. At the same time, pin 6 of MC202 outputs the B+ voltage to power MC20. Pin 2 goes low to provide a current path for the power relays K60 and K602. Simultaneously, Pin 3 of MC202 goes high to bias the PFC module MC70. The rectifier D603, 4 rectifies the 20VAC from the relay and outputs to the PFC MODULE MC60. The DC voltage from the rectifier is converted to 395Vdc by MC60 to improve the power ratio. The 395Vdc is then applied to the switch mode power supply that consists of T20, MC20, and switching circuit. The output of the secondary of the transformer T20 provides the AC voltage that is rectified into the VSUS voltage. The Sustain and Scan operation circuits use this voltage. 80
