This LCD could have a defective back light inverter board.
If your TV is less then a year old, still under manufacturers warranty. If not, I would suggest to contact sony and ask them for parts availability.
Let me know if you need further assistance.

SOURCE: My Sony LCD TV KLV-32V400A

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.

I brought Sony Bravia KLV-32U300A 32 in. HD-Ready LCD TV 4 years ago now it's screen fill with lots of tiny lines difficult to see pictures. i submitted it to service man. he told me problem is on...


This is the main fault, that most Sony LCD TVs. The actual cause is with a faulty T'Con board. For most Sony LCD sets, this part [T'Con board]; will be a built in part with its display panel, and can't be replaced. Display panel replacement is the only repair work. Nothing can be done, even for the authorized service center. If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience.

To turn on the TV:

Turning the Display On and Off

There is a power switch on the bottom of the display and a power button on top. The power switch is used to cut off power completely, whereas the power button turns the screen off but
allows the remote to continue working.
To turn the display on:
1. If the power light on the front of the display is off, turn on the power switch on the bottom of the display.
2. Press the POWER button.

To turn the display off:
1. Press the POWER button.
2. If the display will be unused for an extended period of time, turn off the power switch on the bottom of the display and disconnect the power.

Please make sure you rate my answer 4 thumbs up! Thanks so much for understanding, it would be a huge help to me. I would be forever grateful if you could do this for me. If you still have a question or concern about this problem please just respond / reply to my answer here before rating my answer.

Thanks
