Vizio d55u-d1 no picture or backlights. The capacitors look normal and no burn marks on the boards. I turn it on and the power lights fades, blinks 15 times then shuts off.

There are (4) 1000uf @35V capacitors all together on the DM board that need to be replaced some models have 1000uf @ 16V but they are all right beside each other and all rated at 1000ufs the voltages will be stamped on the capacitor along with the uf ratings.

Does LCD screen backlight come on? If so proceed....
USE:CAUTION WHEN DOING THIS....
Try this if repairing yourself...find power supply, small board with no cover over it...check voltages on output pins/plug/connectors (white plugs) three in a row...
1 Plug has 24Volt supply..1 has 12Volt supply and 1 has 5Volt supply when read to ground (screw that holds board in) if you have these voltages it's a safe bet it's the main control board...I just replaced mine and it fixed a problem like yours.

If the capacitors have blown then it would not cost much to change them all, Capacitors in LCD tv's are a common faulty due to poor chemical compounds used to make them and heat exhaustion, especially with the tvs that have the same chassis. Try changing them all and see if it makes any difference. Vizio or other manufacturers wont say anything as its not under warranty and they dont like people looking inside their tvs :).

SOURCE: Where is the backlight inverter located in vizio sv471xvt?

Larger sets such as the one you have, will have two inverters. They usually are attached to the backside of the LCD panel on the left and right sides. If you don't see them there, then your inverters are built into your power board. If your power boards are either one of these below, then that is the case. If your inverter circuit is at fault, you will have to replace the entire power board.

Are you certain the replacement power supply is good? A defective main board or power supply can cause this problem.
