Samsung LCD TV 8500: USB Stopped Working

by KupaTrupa / January 1, 2011 5:31 AM PST

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.

Please help?
Thanks so much,

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.

I'm very sorry to hear that has happened. The original poster never mentioned his full model code. In order for me to better help you, could you please provide for me the complete model code for this device?

I hope I can get this issue fixed for you!

Mine is a 32 inch LCD series 4 450. Model No. LN32D450G1DXZA Type No. LN32D450 Version AO03. Thanks for the response! Like the original poster, I loved this feature and I really wish that I could fix it somehow.

I had an issue once, where i had a heavy drive hanging out of the USB port, and it actually slightly warped the metal edge of the port, itself, with the weight pulling down. Thus, the connection was no longer tight, and it would not recognize the drive. I simply tightened back with my fingers, and all was good again... Maybe its as simple as something like this.

THanks, that very well could be the case, I was using a big external hard drive... I'll take a good look at the port when i get a chance.
