Don't let toddlers play with remotes, as they can accidentally find hidden features. Or take the batteries out, and they will soon get bored.

Various generic ideas in this link. Google knows everything!

Maybe the toddler reformatted the drive?

I'm trying to play movies from my USB port, but when I plug it I can't .... My LG 47" TV will recognize and open the flash drive, but shows empty.

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.

Hi
Most recent laptops come with a port to connect to a TV, depending upon the input ports the TV has. The two most common are VGA and HDMI, and you will need to check which of these each item has. It is then simply a case of getting the appropriate cable to connect the two together, and then on the TV select the input from the menu, and on the laptop, make sure that the external video port is active (usually a Fnct and "F" key - eg Fnct + F5 for a Toshiba Satellite Pro U200).
Hope this is helpful, if so would you please register that with Fixya
Cheers

I suspect that with the age of the tv that it does not support videos from the USB drive. It will support update files for the tv itself which is normally something a technician would use it for.

Is this question about watching movies made on the Meep on your TV? As I believe this has changed along the way, the OSI call center would be best able to answer that question.

Step 1. Connect your storage device (I usually use a pen drive) to your computer

Step 2. Copy Movie to the storage device

Step 3. Eject storage device and connect to your ps3 via the USB port.

Step 4. under videos an option of your storage device should be there but do not choose X button instead press triangle for options, then select display all.

Step 6. Locate your movie and select it using X button.

Step 7. Enjoy the movie!!!! This works with MOST movie files, you may find problems watching some movie because of the way they were encoded.

Step 8. Done.
Good Luck

Some VHS have a tracking button that allows the user to tune to the best signal. Usually that tracking function is used as follows.
While movie is playing on the VHS unit and signal gets fuzzy, press the channel key repeatedly (for example >> to increase the channel number). f after awhile pressing the same channel change button does not find a better picture, you should press the other channel change button (to decrease the channel number <<) to see if the picture improves.

If that does not work, IT DOES NOT MEAN that you tv/vcr combo unit is defective. It could just be the movie. The tape is magnetic and it might have been accidentally demagnetized.

If picture is better with another movie/tape, your unit is definitely OK.

The only way I know is to reinitialize the set. You do this by pressing Menu on the remote control, the pressing the number buttons 2,2,7,0 in sequence. using the remote, press the adjust button to hi lite INITIAL, then press enter on the remote. this should put it back to out of the box settings and clearing the parental lock code.
If you have kids, I recommend they do not watch you do this.
Good Luck,
