My music files loaded on flash drive do not play on my TV having usb. I can play the music files on computer but not on TV. Please advise

Hi.. there various factors which affects it. First you need to make sure that size of the pen drive is supported by your TV. Secondly, you can only play music files those are supported by TV, one more thing, try to remove all files and only keep music files with in the drive. Also try to have limited number of files , say 50 files and then if it works then try to add more files.

A friend of mine had similar problem and was resolved after formatting drive and only copying music files into it.

Try formating your Pen drive to FAT. Some pen drives come formatted as NTFS or FAT32 that your TV may not support.
BTW,which TV do you have?
