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).

SOURCE: 52'' Sony Bravia will not turn on

Its fixable problem like power supply board replacement will solve the problem.
Unplug tv from wall socket for couple of minutes, replug back in and turn it On.
If problem still exist then most likely power supply got fired and will be replaced, local tv repair shop will help you to replace power supply board.

Sony KDL-52V4100 TV turns on for less than a minute then loses picture, why?

Nice TV ,but, is an LCD . most likely cause may be after long service life the 'Cold Cathode' tubes have begun to grow a carbon track down from the high voltage input . This causes the power supply for that voltage to determine too much load and shuts down . I am surprised you do not see a flashing LED pattern but this does not mean that the condition was communicated to the ECU .
That is a lot of tubes to change at about 40 usd for 10 pieces . It is also a Pain in your seat cushions to disassemble to confirm (ie: delicate connections to undo , mechanical puzzles to solve) I have seen Youtube videos of people converting to LED backlights with very nice results . It is possible but not recommended to change just the bad ones , you will soon have to do the rest anyway .
There may be a shop that does it often and could save $ compared to replacing with LED tv set that size or maybe a shop that converts(not me!)

Take any video source that you know works and connect it to a specific input on the tv. Then press the input button on the remote untill ou get to that input. If you still only have a blue screen the contact Sony for the nearest auth service or call the retailer where you bouht it to see if you can get it exchanged.
