I'm sorry to hear that you're having this issue with your Blu-Ray player.
Try turning on the unit and making sure the disc tray is empty. Then press and hold the FF>> button until the unit resets.
If you still continue to have problems, you may need to contact the Samsung customer service center for live troubleshooting, since that kind of back and forth troublehsooting conversation is much more efficient on the phone than a forum .
They can be reached at 800-SAMSUNG.
My BD-C5500 AXX freezes while trying to play various Blu ray titles that I own and have rented it will start loading and it has played the titles before the last firmware down load. I have reset, have latest firmware 1025.1. I loaded firmware via LAN and tried loading via jump drive(tells me I have latest version) It freezes on menu window on some, cannot read disk on others. Is it now a brick or are their other options?
