Vizio V585-H11 blinks white screen

Woke up one day to our Vizio V585-H11 not working. When powered on, it blinks white and black over and over forever. The audio works fine. Have gone through all of the standard options of troubleshooting to no avail (factory hard reset included). I even replaced the TCon board. I know nothing about TVs but read somewhere that most problems are solved by changing the TCon board. Not in this instance. Any ideas? The lights and everything seem to work and it has power. All connections seem fine. Am I down to a mainboard replacement? It literally blinks all white and all black with zero picture on the screen. Help!!!

I've seen this issue many times on this series of Vizio sets, you have a bad EEPROM IC on the main board, either change the main or order and solder in a new IC if you have advanced soldering skills, needless to say the chip will be a fraction the cost of the board.

Need advice in fixing Vizio TV model V585-H11 Video

It can only be a bad connection or one of the 'new' boards you put in was faulty. Start swapping back the old boards one at a time. Make sure any ribbon cables are properly seated.

This Tip I wrote a while back explains the problems you face.

What might be the problem on my Vizio XVT373SV HDTV that will not turn off and on properly?

Fault to its main board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ . In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Vizio m470nv will not come on, logo blinks orange to white.

It may not be the caps at all, a lot of the new LED Back-Lit TV have faulty LEDs. They short and pull down the power supply, and to a novice it will seem like a bad power supply. That means that you must replace the bad LED's in that particular LED strip before you can fix the problem. Not an easy repair for a rookie.

I have a Vizio VW42LFHDTV10A -- The first time I

Please check for bad electrolytic capacitors on both main board & power supply, if there is any "pup-up" one, replace it (them).
