I can now only charge devices with the port... it doesn't recognize anything anymore. Was working fine, then all of a sudden didn't.
My 8500 50" LCD TV is less than a year old, after about 6 mos. of light use. After a few months of using the USB port (with thumb drive) for movie playback (LOVED that feature!!) it mysteriously stopped working. There is power to the ports. Any thumb drive I insert (either of the two USB ports) is not recognized by the TV. Samsung serviceman came and replicated the problem. Decided it was the motherboard which he replaced. New motherboard - still no USB recognition. Wants to replace the 2nd motherboard again with a new one.
I suspect this is not a hardware issue, but a software issue. FYI, there was no initial firmware change leading to the dysfunction. It just worked one day and not the next.
Technician suggested it may be a virus transferred from my computer. Even though I'm on a Mac (with little chance of virus), I opened a brand new thumb drive in front of him, inserted it in the TV (with brand new motherboard) and thumb drive was not recognized. Virtually nil chance this is a virus-based issue.
Samsung technician and I are both in the dark. This is a critical feature of this TV for me, gotta have it or no more Samsung. Would really appreciate any leads that can help to solve this issue.
Thanks so much,
