Sorry to hear about this. Could you tell me what other devices you're using with this TV, how they're connected, and which ones are behaving this way?
Plasma TV PN43E450:
The only available cc feature splashes the closed captions across the entire screen on a solid black background and in huge letters obscuring much of the real estate.
There are several apparent choices to make changes, but none of them is active and thus cannot be set. Since I depend on closed captions, this is a serious defect because of which I am thinking of returning the item.
I cannot even access the Samsung email department because the last step in the screen questionnaire "what is this question about?" will not allow entering an answer.
Likewise, registering of the product is a nightmare and approaches the same difficulties as requesting secret clearance from the Pentagon.
I hope this forum is monitored by a Samsung guru.
