Re: My LG tv dont remember settings
Usually problem can be with embedded code bug writing into memory or circuit related issue or the chip gone bad. But u cannot solve any of these issues as its completely packed TV from OEM.
U can try doing manual factory reset completely, delete all data if any on TV, disconnect TV from all inputs and after some time try again to set it to ur settings. If this does not solve, better go for nearby LG repair center.
Hope that helps!!
