Vizio TV,  E322VL
Reason for Service:  When you turn set on, the logo goes from amber to white, but keeps alternating amber, then white.  Set won’t start.
Solution:  Replacing main board didn’t seem to fix the set.  This set has built-in Wi-Fi, and requires a couple of minutes to initialize the boot up.   Set okay after that.
