They broke it, they fix it. In the USA call 1800SAMSUNG and don't go nuclear. See if they have a fix ready and if they want to have you pay, say no and insist they broke it.
I did a firmware update to my Samsung HDTV LED 55 and now I have issues with the screen having black borders top and bottom, and also the chyrons are smaller fonts and fuzzy-hard to read. The TV was working just fine prior to update. Gawd, what a mistake I made. Most of the channels(95% of them) have this issue of solid black bars on top and bottom of screen. Only about 5 % of channels have a full HD screen. This all came about because I updated the firmware. No previous issues with TV before this. Can anyone help suggest how I can possibly revert to the old firmware-go back to the old firmware and just leave well enough alone. I just don't want to call Samsung to have tech come out and fix. I live in So. Calif. just curious, could someone maybe give me a rough idea on what a service call might cost to come fix my TV. Trying to avoid this if possible. Please help
