Is there a software update for polaroid P32LED13 tv as mine will no longer play video files from the usb port

the model you listed will not do anything with the usb port, except maybe charge connected devices. The usb port is not an input. Its only purpose is for troubleshooting and factory service.

Yes, if your tv has the appropriate software built in to play the video files on your stick. It has been my experience that many tv's lack the proper codecs for playing some files. Your blue ray dvd's with the usb input usually play lots more of the files.

Make sure your TV will accept video files. Most USB ports were made to show still photos and to update the software in the TV itself. Newer TV's can play video files, but make sure the file format is one that the TV recognizes.

First ya need the Android TV web browser App either on your TV or download from http://play.google.com/store to your TV (Some how) and then browse http://play.google.com/store to find and download the Correct Android TV MOVIE App;
To play Movie files IE: .mov, .wmv, .avi...
Might need to try a few to get the right one :(

The USB port is for viewing still pictures and updating the software running the TV

That's not possible as the TV would need software to decode and play the video. That model of LG TV isn't listed as being a "smart" tv that can play video files. You may have to look into a separate box that can play movie files like a Roku or an AppleTV

The usb port is only for still pictures and updating the software in the tv. It will never show video

tried with other files doesn't work like mpeg4, divx and jpeg?

IN MY HAIER LCD TV L32M3
video files are not being detected from usb...

First verify the exact Model Number of your TV. Mine is a 42PF7220A/37.

go to:
http://www.p4c.philips.com/cgi-bin/dcbint/cpindex.pl?ctn=42PF7220A/37&scy=us&slg=en

On this page I found listed under "Software & drivers" the Firmware Upgrade Software 42PF7220A/37 v1.5.0.0

I downloaded the compressed file and extracted it to a USB Flash Drive.
After you extract the file you will have 2 files...."autorun.upg" and a "readme.txt".
Print out the readme file the delete it off the USB Flash Drive
Make sure the USB Flash Drive has only one file on it (autorun.upg)

Then just follow the instructions from the "readme" file.

Fixed the "Menu" problem for me.....
