I have LG TV 42LD550. When I try to play a movie from Flash drive using YSB it get the message "There is a problem with USB. I have used the format MacOS Extended (Journaled) as well as FAT.
To use a USB flash drive with the LG 42LD550, the drive must be formatted as a FAT32 or NTFS device. The drive should be 32GB or less. Not all USB devices will be recognized - this can be a driver issue. (I've had a few devices that didn't take a USB flash drive, if the drive required a driver to run under Windows 98.) If you use an external drive (portable or desktop), keep the drive capacity to 1 TB or less.
Next what files are on the drive? This TV will only recognize JPG images, HD DivX (.avi and .divx) movies and MP3 audio files. The not all codecs may be supported with these formats. Some people report losing the ability to play movies after certain firmware updates. If the drive has too many folders or files in a folder, it may not work. (This will happen sooner with the FAT32 format.) See page 96 of the user manual to see the file format limits on the USB port. The manual is available on the TV support page: https://www.lg.com/us/support-product/lg-42LD550 . The current link to the manual is http://gscs-b2c.lge.com/downloadFile?fileId=oqXZ71Wn8YXJ3OKzy9leAw .
I hope this helps.
