HI Dears,

The tuner in my UA55RU7100 TV stopped working after I accessed the service menu to make some screen adjustments. I changing the TV service menu, The TV cannot find digital channels.

Now the only way to display the image on the TV is to use the HDMI input.

After changing the tuner model in the service menu section and turning the TV on and off, the tuner settings return to their original state.(S_T2C)

I LIVE IN IRAN
