Panasonic TX-L42ETW5 Device does not start anymore, stand-by LED lights up red, no SOS error code
Manufacturer: Panasonic

Type: TX-L42ETW5

Chassi: LA35



Hello everybody,

I could determine or measure the following with the device:

Device does not start anymore, stand-by LED lights red when device is plugged in and flashes red as soon as an IR command (key press) is sent via the remote control. Voltages of power supply STB 5V and signal LCD_TV_SUB_ON come from A-board. Power supply starts, supplies P15V and SUB1.1V, 1.5V, 1.8V, 3.3V, 5V, HDMI3.3V and USB5V are generated on the A-Board (stand for about 2.5 seconds). Then signal LCD_TV_SUB_ON goes low (voltages go away to STB 5V) and after about 2 seconds back to high (endless). What is missing is the voltage PNL12V which is switched on by PANEL_VCC_ON2. PANEL_VCC_ON2 always has a low signal and does not change its state. Power supply also provides for the 2.5 seconds the 24V for the backlight. Clocking of LCD_TV_SUB_ON starts immediately after plugging in the mains plug (also without IR command). SOS error code is not output. The over-voltage circuit in IC 5000 pin 7 also does not respond. Attached is the timing diagram from the technical training of Panasonic where I have drawn until when the boot process behaves normally.

In my opinion a mistake on the A-board? Does anyone have a tip?

greetings

Andi
