My hannspree tv doesnot play all the movies from the USB or i have image with out sound or i have image and sound and subs

Some TV models have a USB port so that users could play videos and movies from USB on TV. You can try the following steps:

1. Connect your readable and writable USB drive to computer
2. Copy your movies to USB drive and then disconnect your USB drive from computer.
3. Connect the USB device to the Sony TV USB port. Turn on the connected USB device if necessary.
4. Press the HOME button on Sony remote controller to open the menu.
5. Enter the target USD drive.
6. Select the file you want to play back, and then press the play button to start playing movies on TV via USB drive.
It's quite easy to play movies from USB on smart TV devices.

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 :(

Usually you play a movie that is stored on your USB ram disk that will plug into the USB port of your TV. The movie will then load into the TV's CPU via the USB port with both video and audio signals decompressed from within the TV's CPU, then the image will be displayed on TV while the audio will be output through the TV's speakers. So there is no need to have a separate audio input USB port.

sounds to me like a design limit on the TV.

I'm not familiar with your unit. However, this is normal, since the "sub" is encoded separately in movies. I have a separate sub for my front speakers. Or if you know what you're doing you can redirect the front signal to your sub by using a switcher when you're listening to cds, then switch back to surround when watching movies. But again, you have to be experienced in the principle of A/V configuration.

If this is a flat screen maybe the TV isn't capable of decoding the audio you have for the movie. Check to see what audio the TV can decode. For instance: MP3, AC3 etc and check the movie file with a app called mediainfo and go to the audio section and see if your TV is capable of decoding that audio. Also check the extension of the movie file and see if the TV can play those as well. MKV, AVI, MPG, etc.

If the picture shows a picture briefly upon power up then goes off after a few seconds, you have a back light fault. It could have a problem in the 24vdc circuit, failing back light inverter board, or a blown CCFL lamp.

It seems that subtitle file must have exactly same name as movie file. For example: Movie file: Mission impossible.avi Subtitle file: Mission impossible.srt or Mission impossible.sub or Movie file: Mission_impossible.avi Subtitle file: Mission_impossible.srt

I would advise knocking down the resolution. Try and use software, like red kawa, to convert a few of your movies to different formats till you find a decent one. A widely accepted codec setup is Divx/XVid (both are the same) and MP3 sound.
