I would suspect the backlight inverter is faulty:

I would try to look on the power supply first for popped capacitors that supply the 24v rail for the backlight inverter.

Having sound is a positive when it comes to repair. This means that only your screen is not lighting.

If you repair the 24v line and check the 5v feed also going to the BN_on (on) the backlight inverter and you still have no picture...you will need a new inverter.

This could also be the CCFL bulbs that are aging and need replacement. Those are around $20 each for a bulb

Hope this helps! Please rate :)

I am having a similar problem. Try reseating the ribbon cables being very careful with the clips that hold them. On the T-Con board. Sounds like either the Lcd panel screen itself or the t-con board.

Dark area on Sony LCD screen model KDL-46XBR4


This model of SONY TV uses a Samsung display panel, the problem you have is the panel went bad.

SONY was offering an extended warranty to change the panel free, please call SONY to check it out that if they still offer the free replacement.
