All digital TVs contain a secret service code which allows you to change some internal settings like picture height, width, position, colors, etc. Basically this service menu is used by TV mechanics.
Here we are sharing service codes for LG and Sony TVs.
For Sony TV:
First power off your TV using remote, then Press <Display> + 5 + Vol Up + Power button simultaneously on remote.
To save the changes, just press Mute + 0.
For LG TV:
Press and Hold <OK> button on remote as well as TV panel at the same time for a few minutes.
To save the changes press <OK> in Remote.
PS: Be very careful while playing with the service menu. If something goes wrong, just switch off the TV and switch on it again.
