TV Repair Questions? Ask a TV Technician for Answers ASAP
Hello and sorry to hear you're having trouble.
Is there currently an ethernet cable plugged into the tv?
What is the model number of the tv?
Hello, it appears your question is still open.
I haven't heard back with the info needed to get into specifics,
but if you still need help I can give you some general info to get you started.
Please to into the samsung setup menu, and look there for the Diagnostics/Support option, and then for Reset (factory reset), using pin 0000.
After resetting it will try to connect again.
Let me know how it works from there.
