i am not sure if this work on yours model too, try this

put the TV in stand by mode, then with remote Press “i+ (info)”, “5”, “Volume +” then “TV power” on, You can see Service Mode on display

to active rewrite date mute, 0

to navigate 1,2,3,4

change value 1 increase 4 decrease

be cafull . suggest you take photo first on each page you try to change to go back as default if need later.

on his photo the stand by LED ON. the timer one / sleep on the left side.

it may one caused this that his 50 MB need to write the register of the PSU. as 50 one different .

by display, 5, volume down and power on. he can log at self diagnose to read the register ..
or he did change one data Value at time he rolling down to change size.

Maybe try a master reset if you can find how to do so.

read this again please. if you was sure didn't change other data value at service menu, then the PSU register at NVM doesn't match. if you don't know how to write it i suggest you leave it as its and enjoy using it.
