Hi,

I've UN40D6500 and I perform firmware downgrade. Now tv opens, start to show channel and 10 seconds later screen goes off and on again then after another 10 seconds tv close and open itself. I tried to unplug and remove CI card but nothing changed. I want to try factory reset but I couldn't find where it is. Can somebody help me?

Thanks,
Enver

You have to call service. Firmware install procedure error. Nothing helps.

Thanks, Service came yesterday and did factory reset but didn^t recover. They took tv to repair.
