Troubleshoot for Picture/Sound Problem : Customers also can check the picture and sound by internal data. If the picture and sound is no problem, the reason of trouble is mostly not a TV. How to display : Menu HELP TV Self Test #)The test pattern and test sound are created by the main IC on the A board.

Troubleshoot for Picture Problem -1 :When abnormal picture is displayed, troubleshoot by the test pattern in LCD module. How to enter : GX/HX series except TX/TC-**GX7##, TH-**GX6## : While pressing "volume(-)" button of the TV unit, press “Yellow" button of the remote control 3 times within 2 seconds. only TX/TC-**GX7##, TH-**GX6## : While pressing "volume(-)" button of the TV unit, press “Yellow" button of the remote control 3 times more than 2 seconds (more slowly) All GZ/HZ series : OLED While pressing "volume(-)" button of the TV unit, press “Yellow" button of the remote control 3 times within 2 seconds. Press “OK” button of the remote control, the patterns will be changed. (Before OK button= RGB bar will scroll, After OK button= color full screen patterns will be displayed) How to exit : Switch off the TV unit #)The test pattern is created by the circuit in LCD Panel Module(T-CON board). Some patterns are automatically changed. The patterns are depend on the LCD panel.

Troubleshoot for Picture Problem -2 If the picture is no problem, A board must be defective. If the picture is also abnormal, LCD panel module must be defective. Just in case, confirm the flat cable connection between A board and T-CON board.

Exception of Picture Problem ( only T#-40GX###/HX### ) For T#-40GX###/HX### : There is a case that SOS1 doesn’t occur. When there is a problem at left half or 1/4 left screen area, it might be panel (backlight LED) problem. Check also the SOS1 troubleshoot method (P3 connector), “Troubleshooting for LED Blinking ( 1 time blink ) for A+P type” Other models happen the shutdown and red LED blink one time, but only these models might not shutdown.

3-2. Stand by / Start up Operation *1) The main difference from FX/FZ series is power IC for Stand by, from IC5000 to IC8902 and 5290. (operation-4) Only TX/TC-GX7##, TH-GX6## are same as FX series. *2) The explanation is for the case of “A+P”, but “A+P+LDP” cases are basically same start up operation. *3) OLED models are also same start up operation.

When the TV is plugged in, the power board outputs 5V for standby voltage. When the power supply receives the TV_SUB_ON signal, it outputs 2 different voltages: 16V to the A board on pins 1, 2, 3 and 4 of connector P2. (*)The DC level is different 64V(*) to the LED backlight drive part. by the LCD panel. After A board is ready to display, it outputs Backlight_on command to P board.

When the TV is plugged in, the rectifier start to produce DC voltage which leads through PFC circuit directly to the power switches Q7351, Q7352. (PFC circuit IC7201 does not operate at this moment.) Besides this DC voltage is provided also for D7104, D7105 which provide start voltage to pin 1 of power supply IC 7301. When the voltage on pin 1 rise up to predefined value IC7301 starts supplyinng of switching pulses for Q7351, Q7352. Due to this current starts to lead through winding of T7301 which starts to generate output voltages. One of these voltages VCC is used for power supplying of the IC 7301 to its pin 10 When the power supply starts up, the 16V is providing by D7421/C7423. This voltage leads to IC7491, which is 5 volts DCDC converter. This voltage (STB5V) is provided to A board via connector P2 pin7. So if the TV is plugged in, STB5V is provided to A board without trigger signal.

The STB5V from pin7 of connector P2 is applied to the Power IC(IC8202, 5290) for supplying power to the Main CPU (IC8000) on the A board. The IC8202 converts the STB5V to STB1.2V and STB1.05V and IC5290 converts the STB5V to STB3.3V. These voltages energize and prepare the microprocessor (CPU) for program execution. The STB3.3V is also applied to the remote control receiver and the power LED on the K board through connector A02/K10. When the Power Switch on, the key3 signal is grounded. (#1) The IC8000 lights on the RED LED and is ready to power on the TV by receiving the Power switch on, Remote on, Viera Link and so on. This is a standby state. (#1)Only North America model: Power switch on is no need, automatically this procedure is operated after the TV is plugged in. But the RED LED does not light.

When the power on command from the power switch, the remote control and so on is provided to IC8000, IC8000 first outputs the “TV_SUB_ON” command. The “TV_SUB_ON” command is provided to power board via pin 9 of connector P2. (*) Just after transition to Stand-by mode, the TV_SUB_ON(16V) output for a while.

When the power board receives the TV_SUB_ON signal from IC8000 via pin 9 of connector P2, it outputs 2 different voltages: 16V to the A board on pins 1, 2, 3 and 4 of connector P2. 64V(*) to the LED drive part. TV_SUB_ON command is carried to the primary side by PC7302. This voltage is leaded to Q7301 which provide power supply VCC of PFC circuit. The PFC starts to operate. Besides this voltage to go to Q7302 whcih provide the mode change signal to pin 3 of IC7301. The operation of the IC 7301 changes the switching frequency from standby state to working state because of providing high power current. Output voltages from transformer T7301 start rising up until the moment when IC7401 started to operate. This IC measures the 16V line output in the secondary side. The output of this IC is provided by PC7301 to pin 4 of IC7301. IC7301 adjust the switching frequency by this feedback signal. The TV_SUB_ON signal also switches on the Q7402/04/21/22 to provide output voltages (16V and 64V(*) ). The 64V(*) is provided to the LED Backlight Drive. The 16V is provided to the A board. (*OLED) GZ/HZ series : The VCC of PFC also go to IC7500on P/PB board. This power IC start working after coming the EVDD_ON signal. (*)The DC level is different by the LCD panel.

The 16V(F15V) from the P board via pin1-4 of connector A02 is applied to the Power ICs (Voltage regulators) on the A board to generate the SUB-Voltages used for signal processing operation. : SUB1.0V, 1.8V, 3.3V, 5V and 5.3V Each voltage regulators start up by high state of DCDCEN signal which is pull up to F15V. So F15V is provided to A board, each SUB-voltage regulator ICs start output.

The F15V is also used to generate the PNL-Voltage on A board. IC8000 outputs the Panel VCC On signal. IC5260 starts generating the PNL12V by this signal. The PNL12V is provided to T-con circuit of the LCD Module.




After that, IC8000 outputs the BL_ON command to the P board. That command turns on the IC7800 for LED backlight drive. Then the 64V rise up over 110V(*) and output to the backlight on the LCD panel. The backlight starts lighting by PWM signals, and LCD panel displays the pictures. If the backlight drive circuit does not work normally, the BL_SOS signal is informed to the IC8000. At that time, IC8000 stops outputting the TV_SUB_ON signal and blinks the red LED 1 times. (*OLED) GZ/HZ series : IC8000 outputs EVDD_ON (instead of BL_ON) command to P/PB board. That command turns on the IC7500. It provides panel 23V to the T-CON board. The T-CON board starts operation for OLED panel.
