Roku setup

[PetMommy02]

I appear to be signed in on my Samsung Roku tv, but do not know the password it is asking for. The password I think I set up on my PC for my Roku acct has an underscore. I can't find one on the TV, Worse, this TV was given to me by the family of a deceased person and I don't know how to add my accounts so I can use the apps.

As far as I know, Samsung does not make a Roku TV.  Do you have a model number?

There may be a "Roku Channel" app on your samsung TV that is equivalent to the Roku Channel app on the Roku.  (But that is just one of thousands of channels available on a Roku device.)
