LVDS cable from the T-CON
This seems like a problem with the T-CON board or it's connections. This is the low cost method to try.
If this set is under warranty you should return it to get it repaired/replaced by the seller. If not then;
This sounds like the T-CON board or the LVDS cable connection is bad. Turning on and off the set will cause the connection to heat and cool and not make good contact.
IF YOU KNOW HOW TO WORK WITH ELECTRONICS REPAIR(board replacing ) or have a friend with knowledge/skill you can fix it.

>Unplug the set and disconnect any cables.
>Lay on a flat surface covered with a cloth.

>Remove the back cover.
>The board is located near the middle of the set underneath metal shielding.
> Re-seat the cable by disconnecting and re-connecting the flat cable(s) connected to this board. See if the picture corrects.
You can try this several times.

If this does not correct the problem you may have to replace the T-CON board.
>Replace the shield and back cover.

You can search for replacement boards from places like shopjimmy.com, ebay and other sites.


The board will look something like this;

I took some photos that appeared in negative. please show me how i can repair those photos. thanks


Many image viewing/editing programs will let you change between negative and positive images, but the simplest thing in Microsoft windows is to just use the built in Paint program. Open the image and select "Invert Colors" from the "Image" menu. You may want to save it out with a different name so you don't erase the original.

It sounds like the T-CON board problem, you can try reseating the connector first, the board is mounted under the metal shield which sometime can be difficult to get to.

Negative image and then black and won't turn off!


The negative image on the screen is the DMD board (Digital Mirror Board). The cycle sound is the color wheel trying to spin but if the DMD board is going bad, it will effect the color wheel and not spin. There for your image will freeze.
