there is a code to get into the factory mode settings, but you must not mess around with any of the other settings in this mode, using the samsung remote, turn off the tv, and push the mute buttin first and then 182 and power button, this will bring up the factory mode, find the reset and push enter, this will restore the original settings to default
Have down loaded and set up new firmware to LN52A750,But would like
the default settings.They may be off set from trying to get a better picture,That is why Samsung had me update the firmware.
Or if there is updated setup for sharper pIcture,or where I can search for the settings. Again thanks for your help. Sid
