You probably need to replace the backlight. In parts less than 30$. If you know your way around these things, or know someone who does, it's not a super difficult thing to do. You can get a tutorial that's written for monitors here: http://www.inventgeek.com/Projects/shorts/lcdfix.aspx basically the same procedure for an LCD TV. Good luck!

Possible there is a disconnect with the main processing section as there is no signal present except the working of the backlight and display.
So it seems the main power to the mother board and the processor must be checked. Also if there is no raster or even OSD- on screen display then the processor must be checked.
Get help from Sony service if under warranty.

The fault is with its T'Con [Timing Control] board. This is the circuit board, that interfaces digital main board to LCD panel. There is no repair to this board, other than replacement. Contact any experienced service technician to replace it. If you have some knowledge in electronics, visit this site named 'Electro-help'. Check this link, and select the site. Pull up older posts there. General methods to replace T'Con board is described in detail.
