My Samsung UM50MU630D display has begun to appear dim after a short time of being turned on. Changing the brightness and contrast in the settings seems to fix the problem for a short while. I also disable the "Eco" brightness and motion detection brightness settings.
When the display becomes dim again, the settings I changed are back to the values before I changed them.
I tried a "hard" power off (pulling the cord) and a factory reset but these did not fix the issue.
It seems almost like there is a battery for holding the settings that is now dead but I assume now days that they would be held in an EPROM.
I'm not to sure how to proceed.
Thanks.
