Re: Vizio E550i-a0 no turning on
So, hold off ordering another power supply until my replacement main board arrives?
Sorry, EE, but not sure of the order of operational voltage on this TV.Leave a comment:

Re: Vizio E550i-a0 no turning on
So, I have this same type of TV from my father in law.
It has the same symptoms. Will not turn on, no LED light in the bottom right.
I have replaced the power supply (Have not check voltages).
I have just ordered a main board. Has this been known to fix this problem???
I hope so.Leave a comment:
