Re: E470VA Flickers
ok would like to try panel because seems like backlight never goes out. So i think its panel did you find out if guy would part with panel. I do not want to spend much it is a risk still may not work. May try main in yours see what happens. I tried inverter you gave me still the same. Tv was having problem from start replaced Main and power first refurbished boards im sure but problem was same next we replaced T-con still the same. Then i tried inverter got from you still does same thing.Last edited by rogmiller; 02-14-2013, 09:00 PM.Leave a comment:

E470VA Flickers
I have a E470VA Vizio that about every 16 seconds looks like it winks at you. Picture goes in then out. I have replaced TCon , Main , Power Board someone said could be a bad panel. Is there a way to test inverter to see if it could be problem.
