Hello,
If you can still hear audio, try to see if your TV has the feature to extend or output the display into a different device like another TV or a monitor. If it works that way, it means that the graphics device in your TV is working and the problem might be your LCD panel gone defective or something in between like the inverter or LCD cable. There is actually no easy fix for this, but you can try to open the TV if you know how and secure the cable connections inside and reseat them if you can. But, your TV might still be in 0 warranty from the manufacturer and it is always better to ask service from pros.
Cheers!

This problems likely the board that call the T-CON decoder board is the causes and the problems.This board sit at the bottom in the middle of the LCD screen panel.Tries websites like Shopjimmy.com,Ebay.com to buy a refurbish T-CON decoder board for the replacement.

It has gone into a self protect mode where it will shut down because you have a fault in the frame stage of the TV (horizontal line). This will most likely be a failure of the frame output IC. Replace this & you should restore the normal picture.

YOu need to reset the lamp use hours after replacing the lamp , as so the optical circuitry can configure and recognize the new lamps prescence. The best bet is to either contact the manufacter or their closest authorised repair agent. Good Luck.
