Hi guys

my mothers LG 49UF770V developed an issue whereas it flickers and is hung on the logo screen .

I have attached a video of the fault

I tried the soft reset

I.e. 25 seconds pressing the power button / joystick and left it 20 mins the plugged it back in still has the same fault

therefore, removed the rear of the tv , removed the mainboard and reflowed it (10 mins in the oven 200 degrees C) and I still have the same fault

Would you guys suggest buying a new mainboard? Or it there another avenue / part it could be?

Thanks in advance
