Bought this TV to fix for myself. Plug it in, touch the power button and it beeps and the power LED turns on, but it won't do much else.
Probed around the mainboard, found that i am not getting PANEL_VCC. Dug some more and noticed that it doesn't get the input signal to switch. Also i am not getting INV_ON (hence no backlight). Forcing the inverter to turn on results in working backlight so the LEDs are ok. Still no picture.
Both these control signals are coming from MCU IC1002, so i suspect a firmware issue. Does anyone have a firmware dump for this board? It is LD01D EAX61766102(11).
