I never received the promised call back from Tier 2 support. I called back yesterday, got disconnected after waiting on hold, called back again, and finally got in contact with somebody. Because the paltry warranty has expired, they want $100 to send someone out, another $90 for any labor, plus the full price of parts. Terrific. And, based on what I've seen, this may not even be a hardware problem.
My LN46B650T1FUZA suddenly stopped interfacing with my PC after having worked for about a year. This led me to believe it was an issue with my graphics card, so I sent it in for repair and received a replacement. When it came back, nothing had changed. I've tried swapping ports and cords and the only thing that doesn't work is my PC. However, I've tried connecting my PC to other TVs and haven't had any issues.
When my TV is plugged in, my computer detects it (and even knows it's a Samsung) but my TV doesn't detect the computer no matter which port it's plugged into.
This looks like an issue similar to one here:
I'm expecting a call back from tier two tech support shortly, but I was wondering if anybody else who has had this issue has ever gotten a fix.
