Question about Sony KDL46EX400 46 in. HD-Ready TV
No power lights, picture or video when we plugged the TV back in. Have checked the wall plug and the cord - both are good
Double check the outlet has power and the plug at the TV is fully seated in.

When the lamp fails in this unit, often the thermal fuse opens. The error code is 6 blinks. To replace this part requires a great deal of deal of disassembly.

It is a real possibility that the power board has failed.
It is fairly easy and safe to remove it and inspect it and the burnt component will be easy to find.
Make sure you place the TV on a flat surface screen down where it is well supported. Do not put anything on the table under the set if there is a chance it will come in contact with the screen. Allowing the weight of the set to rest directly on the screen presents a real risk that the screen will break. Lying flat on a table, the set will rest on the frame around the screen which should be safe.
Do not apply power to the set with the back off as there is a risk of electrocution.
The board is available as a module and can be found on eBay occasionally. The part number is 1-789-496-11 and it will cost between $250 and $300 new.
I suggest you turn the repair over to a qualified service professional for the best outcome. Attempt any repairs at your own risk of creating further damage or replacing the wrong parts. The board failed for a reason. The core cause may not be the power board.

Since this set is still under warranty, DO NOT open it up at all. That will void the warranty. Your best bet is to report the problem and request service. Request that this service be scheduled for a few weeks out and try to see if there is a pattern to when it occurs. For example, does the problem seem to occur most often after the set is on for a while? Any information that you can provide to narrow down the conditions when the problem occurs will be helpful. Please report this as an intermittant problem. Even if nothing is intially found, if the problem becomes more regulatr after the warranty period has expired, it should still be covered.
Keep us posted,

Since the TV is still receiving power, the problem is going to be with the TV's mainboard. After you unplugged the TV and plugged it back in, you said the power light went out again, so I assume the standby light wasn't flashing again? The flashing standby light is indicating an error code so my suggestion is to contact Sony for service options regardless if there is a warranty or not because service is the only solution to this situation. Don't forget to provide them the error code or 4 flashes repeating.
