After several days searching this forum, online, and reaching out to Samsung support for a solution to this problem (to no avail), I am once again bringing this frustrating issue to Samsung’s attention.
None of the solutions provided work permanently… resetting network, checking cables, using ST offline diagnostics, disconnect/reconnect TV/router, resetting TV to factory, using Ethernet or WiFi, deleting and reinstalling ST and/or the TV on the app, creating a new ST login, changing DNS, etc etc. NOTHING resolves the issue and the TV WILL go offline on ST after a while once it’s turned off (meaning routines will not work). When TV is turned back on, ST immediately recognizes it and everything works perfect.
Samsung reps always seem to respond with the same recommendations (most of them listed above), and then “disappear” or “ignore” subsequent requests for assistance.
We’ve all purchased Samsung TVs because we believe in the brand’s promise of excellence. But the way this issue has been mishandled by Samsung Support for several YEARS now (just look it up online!) is simply unacceptable.
Your TV may be set to completely turn off... sounds crazy but ive accidentally enabled power saving features in my settings and rendered it unable to be turned on via Smartthings... the other option is, somehow, your tv got unlinked from your samsung account and now you need to re-sign in... another possibility is remove it from Smart things and re-add it
I can confirm I’ve also previously completed all your suggestions: confirmed all TV power saving options are off, confirmed both TV and ST app are on the same Samsung account, and removed then re-added TV from ST (I did not add these to the completed actions list on my original post as it was already long).
I truly appreciate you chiming in. Hopefully someone from Samsung will at some point.
