The problem is in the verticle section, if you are a technician check a verticle IC and a capacitor of that stage. to allocate a verticle stage follow 4 cables coming down from deflection coils, two of these wires goes near transformer, this is horizotal and the other two goes near an IC this is verticle. positive idea.

try turning off AND unplug for a couple minutes! USB may have pulled power down to start the switching noise. Try usb again and if it does it again then I wouldn't use that usb anymore.

My new lg 3d tv is closng on top bottom and sides is there anything i can do to cure the problem


Could you provide more information? What do you mean when you say, "closing?" Do you mean there is a black band around the picture? If so that means the original picture is recorded at a lower pixel density than your TV will display.
In the past most TV program signals provided a picture dimensions (in computer standards) very roughly 600 pixels wide by 400 pixels tall. What this means is that a picture of that pixel size will display as a small, squarish image slightly wider than it is tall on a (now) standard 1080p LCD television--which produces an image 1920 pixels wide by 1080 pixels high.
That would be nearly unwatchable (picture too small) except for the fact that most TVs compensate for the relatively small size of "standard definition TV (SD TV, as opposed to HDTV) by enlarging the image so that the top and bottom edges of the picture touch the top and bottom of the TV screen. This will leave black bands on either side of the picture. Some LCD TVs will automatically stretch BOTH dimensions of the image, which yields a distorted, "sqaushed" image.
All my comments above apply to both standard LCD and 3D-LCD TVs, by the way.

I have a 22" Logik


The problem is related to the section which processes the video/picture information in the TV. Most likely an IC or its surrounding components.
Try consulting TV repair technician.

All the best

Opeen the back panel of the tv,
near the coil you would see 6 potentometeres, (small turnng things) one is written vhold and and the other horizontal scroll, adjust these to set the picture,, Be careful nt to eletricute your self..

IF THAT FAILS THE PICTURE GETTING WIDER AND SMALLER CAN BE CAUSED BY EIGHTER THE COIL, HORISONTAL CIRCUIT OR VERTICAL CERCUIT.. most often its just a capicator.
