Difference between the PZ700U & PZ750U.
Only the PZ750U series has:
1.Extra HDMI input (Front) (GH Board)
2.Capability of video Playback (Mpeg2/H.264 on SDHC card ) (JG Board)
3.Pro-Setting & Studio Reference Modes
Movie images are some of the most difficult for TV displays to reproduce.
By working closely with movie studios for many years and applying research by the Panasonic Hollywood Lab, Studio Reference Mode on Panasonic plasma TVs enables the replication of colors that was originally intended by the director, exactly the way they are seen on reference monitors in professional film editing rooms.
Pro-Setting Mode offers the precise, highly detailed adjustment of Image quality to suit personal preferences. Just the touch of a button on the remote executes setting adjustments such as tint, brightness, contour emphasis, gamma compensation and black expansion, which would otherwise require the use of special equipment to accomplish.
The PZ750 models have better skin tones/rendering

Power Supply
(STAND-BY)
The Power Supply circuit board used on the TH50PZ/PE700U/750U and TH58PZ/PE700U/750U models is divided into 2 different sections: Multi and Vsus
1.The Multi section generates all the Standby voltages plus the F_STB_15V, P15V, P5V, and Vda.
2.The Vsus section generates the Sustain voltage
21
Power Supply (Standby)
22
•When the TV is connected to the AC line, the power supply outputs 5V.
•The 5V is applied to the D board and the DG board. The 5V on the D board in the Panel Drive Section is not used at this time.
•When the DG board receives the 5V from the Power supply, it outputs the “F_STB_ON” command for 30 seconds.
•“F_STB_ON” command is applied to the power supply board to generate the “F_STB15V”, which is applied to the H board.
•The H board has a DC-DC converter circuit that generates the 9V and 5V used by the H, DG, JG, PB, K, and GH.
23
Standby (TH-58PZ750U)
Multi-Section
24
•When AC is applied to the TV, the Standby circuit on the multi-section board outputs 5Vdc.
•The STB5V is applied to the Power MCU (MC701) and a switching transistor of the power supply circuit.
•The STB5V is also provided to the SS board. A jumper at connector SS34 of the SS board routes the 5V back into the power supply board to turn on the switching transistor. When this transistor is on, the STB5V is output to the D and DG boards.
•On the D board, the STB5V is applied to a 3.3V regulator (IC9011). During standby operation, this regulator is kept off to disable the panel drive circuits. The STB5V is also applied to a 3.3V regulator (IC5604) on the DG board to provide the supply voltage (STB3.3V) to the Main CPU (IC1100). The STB3.3V is also applied to the Remote Control receiver and the power LED on the K board. Furthermore, the STB3.3V is provided to the SD card slot (Not shown in the diagram).
25
•When the Main CPU IC1100 receives the 3.3V, it outputs the “TV_SUB_ON/TUNER_SUB_ON” command to the Power MCU (MC701) located on the Power Supply board. Subsequently, the power MCU outputs the following commands:
1.“BIAS ON” to activate the AC relays
2.The “PFC ON” to start the Power Factor Control operation and create the DC voltage needed by the Power Control circuit
3.“F_STB_ON/OFF_” to command the turn-on of the DC-DC converter (Q305-Q306) and output the “F+15V”
The “F+15V” is applied to the 5V/9V regulator, IC3500, on the H board. The output voltages of IC3500 are used on the H and many other circuit boards. To avoid catastrophic failures, they are monitored by an SOS Detect circuit for over-voltage and over-current conditions. The SOS Detect circuit is controlled by the “TUNER_SUB_ON” command from the Main CPU (IC1100) on the DG board.
26
Standby (Main CPU VCC Supply)
STB3.3V provided to the “DG” board during standby
IC5604 (STB3.3V Reg.)
27
•The STB5V is connected to the D and DG boards. During standby, this voltage is not used by the D board. On the A board, the STB5V is applied to the 3.3V regulator (IC5604) to generate the “STB3.3V”, which powers the “MAIN MICON Genx4” (IC1100). The “STB3.3V” is also connected to the K board to power the remote control receiver and the power LED (Not shown here).
28
Standby (STB5V Actual Path )
29
•This is the layout of the actual location of the boards and the connectors involved in the development of the STB5V.
•The steps 1~5 indicate the sequence of events that takes place after the TV is plugged-in.
