d55u-d1 logo then power off.	Can't Post

So of course my Vizio TV is out of warranty. Recently I have an issue where the logo will display but after 10 seconds it powers off. Being out of warranty I replaced the main board myself to no avail. Before I waste more money solving this problem does anyone have any ideas as to what would cause this problem?

All the boards look good, I don't see any signs of blown capacitors, I'm just wondering what my next step should be, replace power board or replace t-con board.

Vizio tells me it can't be a firmware issue nor will they release the firmware to me.

Any ideas?

As the firmware lives on the Main Board and you've already changed it, that should have ruled out the firmware. Unless the replacement Main Board was defective or wrong version.

Also, some sets will turn off after a period of time if the set is turned on while being set to an inactive Input. Confirm that each and every LED bulb is lit for those 10 seconds.
