Sziasztok!
Ma került hozzám, olyan hibával hogy nem csinál semmit. Kipróbálva megjön a kép, hang is, de két perc után eltűnik a kép és a hang is, és villog a piros led, de bekapcsolni nem lehet a távval sem. A lehúzott inverter panellal is így csinálja, de áramtalanítás után is rövid ideig működik. Merre keresek gondot main board-on vagy a tápegység, vagy esetleg az inverter panelon lehet gond?

Jó éjszakát! Mondhatni, a szokásos. Sorki ég, béraktam amit a HQ adott, valami kínai csoda. Lőn kép, de raszterhibás, nosza bele egy TDA, s lett vala jó kép. Csak egy csöppet kicsi a képméret, és tán kissé buci is de az alig látszik. Állítni kék rajta, (a fejem meg zöld volt miután fél óra alatt nem bírtam rájönni, hogyan).

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
