does anyone know how to reset the service menu settings in samsung model # UN40B6000VFUZA TV? i was trying some of the settings and the one that i cant turn back on to the original setting is the one under
( service menu-then control- then sub option- then SUB U-COM then on-off ) this TURNED OFF the screen and i cant get it back on.. is there a fix or a way to reset the service menu? I'm sure buying a new main board is an immediate fix correct? but is there a more practical way to make the setting appear again?
