I have a UN55KS8000FXZA.
I believe my main board is bad since I have severe network connectivity issues.
Wireless or wired; neither will allow for a stable connection and constantly drop and reconnect several times per minute.
This makes live streaming impossible as it is constantly interrupted.
However, services that buffer (YouTube, Netflix, Prime Video, etc.) don't really have any problems.
Trying to watch live streams like Twitch or TV using my Spectrum TV App just don't work, even when trying to watch On Demand content.
I've done everything on the software side and home network side to try to fix this but, nothing has worked.
(Manually set IP, DNS, Reset Smart Hub, Factory Reset TV, messed with ports on my router, and all the other ideas on the Samsung forums and anything offered from a google search)
Does anyone have some info on removing the back panel in order to replace the main board?
