All digital TVs contain a secret service menu which allows you to change various internal settings such as picture height, width, position, colors, blue back screen, etc. This secret service menu also allows you to enable or disable lots of features in your television set. Basically this service menu is used by TV mechanics.
Today in this topic, we are going to share codes to access the hidden secret service menu in LG and Sony TVs. These codes will work in all types of TV such as CRT, LCD, LED, Plasma, etc.
NOTE 1: Please note down the default values before changing them, so that you can restore them in future if something goes wrong or you don't like the output.
NOTE 2: Be very careful while playing with these service menus. Better to make changes and check their effects first. Don't save the changes immediately. If something goes wrong, just switch off the TV and switch on it again, it'll restore default settings.
