Vizio M3D550KDE

Everything works on this set...except the MENU function. It will appear on screen for 1-2 seconds then disappear. I am afraid the CPY on the main board has issues. Tried to find firmware..no dice. Vizio only provides updates to sets with wireless through the internet. Thought maybe a firmware issue but without MENU, I cannot connect to wireless or wired network.

Could this be caused by a failed U405 as in some other cases?

Possible eeprom fault

Could try this, might not work tho if no menu shows up.

Press the "Menu" button along the left side of the Vizio TV.


Press the "VOL-" button along the left side of the Vizio TV until the Settings icon in the shape of a wrench is selected, then press "CH-" until "Reset All Setting" is highlighted.


Press "VOL+." The Vizio TV will restart with the factory settings.
