Question about Sony Bravia KDL-46V4100 46 in. LCD HDTV
I checked on the schematic, there is a self diagnostic mode for the tv accessed with the remote control. If the TV does not turn on I would highly recommend finding a local reputable service facility as this might be completely a fault inside the TV. https://www.encompassparts.com/shop/model_research_docs/?file=/SON/sm/KDL46V4100.pdf
Please check page 12 for self diagnostic procedure.

The power supply board in your TV needs to be repaired. Please consult some Good TV Tech to do it.

If your set was manufactured around July 2005, you may need a firmware upgrade to solve this issue. On the Sony website you can enter your model # and serial # to see if you TV is affected. If so, it is easy to have done and may be free from Sony. It sounds like the issue they described in the writeup on the required formware update. I had mine done within few months of when i bought it (purchased in Dec 2005) and it has been working flawlessly since.

To wayne: The balancer board is in fact available by itself. You can get it at many different parts depots here on the web. I just suffered from a similar problem, on the same tv and it solved my problem perfectly (Stupid 13 blink, blink code...)
The searchable part number is SSB400WA20. Its referred to as a voltage inverter (for the backlight of the lcd panel.)

Most likely this is caused by a defective main board. Changing the main board will fix the issue about 95% of the time.
To be absolutely sure, the voltages need to be checked on the power supply. If they are not the values listed in the service manual, then you should replace the power supply instead (accounts for the other 5% of the time).
