Logic Control D Board got nothing to do with this problem. This is your main power supply gone bad(usually not the sub power supply). I just repaired my VIZIO by replacing main power supply. Just remove back cover and your board will be right in the middle of the screen. Just get board part/serial # and google it. My best price was through eBay(around $100). Everything is fine now.

SOURCE: i have a vizio lcd
Here is a link to the Online User's Manual for your TV in case you don't have one already:
Some LCD TVs have a fuse fitted right where the power cord enters the case and is accessible through a small removable panel. However, I didn't see any mention of one for this model in the manual or on related forums.
It certainly seems like you are not alone in your troubles with VIZIO products though. See the disparaging comments regarding your model tv at the following link:
Unfortunately none of them seem to have any solutions either.
Sorry I couldn't help more.

Contact any service technician. This is not a service work; can be done with ease by a customer. Especially who is not aware in electronics. Gopakumar Gopalan Google

SOURCE: I will start from the beginning. Back in Sept. my vizio tv would just randomly turn off here and there, but would always turn back on. Mid october the tv randomly turned off and never turned back on.
Claim lightning damage, put old boards back in it, sell new boards on ebay while a shop fixes the set for free (minus deductible paid for by selling ebay boards). Tada, repaired!
Or just sell the panel on ebay and buy another tv. Don't break the panel shipping it.
