MY TV will not keep settings, if you turn it off or change from one input say hdmi 1 to hdmi2 the settings revert back to factory and vise versa if i change from hdmi 2 to hdmi1 or TV they revert, also unable to adjust my 4k settings, the settings are very light. i have tv connected to a 4k source. no matter what it will not let me change them. My software is
PHL-OSOJU_118_0 and i have done the software update check on tv and says its the newest software. Has any any one had this problem and found a fix for it.
