My tv has sound but no picture, when i look slightly closer i can see motions. What should i do?

sounds like a faulty LCD panel

Scene Select: Allows you to easily adjust your TV to the most suitable picture
and sound settings based on the scenes for the best quality result for the
contents genre you are watching (page 20 of your manual).

Additionally do not place the back closer than 3" to the wall, (stand,) 4" on either side and nothing closer than 12" from the top of the TV.

This is mainly for dissipating the heat that the TV creates, but this will also impact how the sound travels thoughout the space.

check your lcd lap drive to see if you have power to the lamp drivers

check the vacuum hose from your booster to the engine

check where your motion bar is located and notice your motions in respect to it. If you are too close your motions will be rash, and thus out of sync.... Try backing up your wii fit board and your stance when playing games. This also gives a delayed response... Make sure you are 6-10 feet away from the motion sensor bar...

Check and replace that board. Just visit the site linked here. Y Sustain board faults and symptoms of plasma display is given in details. http://electronicshelponline.blogspot.com/

I would advise you to contact your LG dealer as there was a software issue which related to this problem & would need to be carried out by an engineer.

Most high end and larger Samsung TV's are equipped with what is called auto motion detection, more or less the TV tries to anticipate where the movement is going to be. The reason your getting the trippy pictures is because the tv's refresh rate is probably twice as fast than the source feeding the video.

To turn this off just go to your menu and scroll down and choose picture option and find auto motion and turn it off there it is problem solved! It won't hurt anything and can be turned back on as easily

Your degaussing circuit is not fully 'demagnetizing' the picture tube.
You can manually degauss it using a strong magnet, but it's tricky.
With a tool made for demagnetizing you simply hold it close to the center of the picture tube and using a circular motion slowly spiral outward to the outer edge of the tube, pulling the magent further away from the tube at the same time. The same can be done using a strong magnet although the results may not be perfect. You can experiment with a magnet using wiping motions as you bring the magnet closer to and further away from the tube.

well check wires that all input output wires of your tv are in place and they are properly inserted!!!if this doesn't solve your problem then u need to go for repair!!
