The system is of the seagate hdd is the same as my previous hdd
You are suggesting this setup worked perfect with your old HD, I take your word for it.
TV HD hookup is finicky, you must read the manual carefully, and even then sometimes they don't tell you the fine prints as if this particular feature, they just throw it in to sell you the TV but not enough information so you won't go "oh, is this limited? moving on to look at the next model."
So if you say SAME, it must be EXACTLY the same and I mean SAME FORMATING (most likely same form of FAT), SAME PARTITION (MBR vs GPT, size).
