Sony Bravia KDL-46XBR4 - Blank Screen Can't Post

I have a Sony Bravia KDL-46XBR4 which when I turn on has a Blank Screen. Can anyone point me in the right trouble as to where and what to troubleshoot?

Where is chapter 5 of that posted manual? It says if no backlight is present when removing the back cover refer to chapter 5. <br>

Also flowchart C is missing.

I gave the info necessary to determine whether your "Blank screen" was a 'No Video' or a 'No Backlight' condition (I was anticipating needing Flowchart 'F' or 'G.') (You made No mention in your initial post that the set was shutting down, nor the red Timer LED was flashing.) Flowchart C would cover the red Timer LED Flashing.

I do NOT have your TV in front of me. You have to specify how you are arriving at a conclusion.

"If the back cover is off, there are numerous holes in the rear of the panel chassis where the backlights can be easily seen. In almost all cases where the backlights do not light, the unit will shut down and indicate a diagnostics failure that will appear as a 6X (inverter) or 13X (balancer). This scenario is covered in Chapter 5 of this manual."

SO .... Flowchart A: 'Is red Timer LED Flashing?' (HOW MANY Flashes? 6 or 13?)

The backlight and picture finally came on. Only issue now is that there is some distortion in the bottom right side of the TV (approximately 3" high x 12" long.

I also noticed that the power button only works when turning the set off.
