I have a 47PFL7606H TV and a 500GB USB 2.5 external disk (imation) but they don't want to play together.

When I plug in the disk nothing happens, however if I plugin a 4GB usb flash it starts listing the contents.

I tried formatting the disk in fat, exfat, ntfs, partitions with only 1GB...and nothing works.

How can I solve this and use my USB hd?
