Re: Vizio E220VA no power
Also is it possible just to short the on switch to a standby rail with a resistor to maybe kickstart the tv?
Again I'm new here.
I've looked at EEPROM symptoms and I'm not completely convinced that that is what is wrong with mine.

Re: Vizio E220VA no power
Is there a way to fix the issue other than buying a part or a new board?Leave a comment:

Re: Vizio E220VA no power
Did you see the pic I attached earlier about a potential cross connection.
Also I got the readings
-701
5.09
3.3
0
-702
5.1
3.3
0
-703
3.3
1.2
0
-704
5.1
3.3
2.04
I will do some testing on the resistors tomorrow but everything looks sound.Leave a comment:

I've read that thread through I'm not sure I have the same problems and that is why I made a separate one.Leave a comment:

Re: Vizio E220VA no power
Started using an old smartphone for pics. I think its a bit clearer.
Ok I did not get any change in voltage but I just want to double check that I'm doing this right. I looked for DC voltage and saw no change when the button when pressed. Heres how I'm reading it

Also in this album is a picture of something on the power board which looks to me like 2 wires are touching each other (visible at top right). Upon a continuity test all of those pins are connected...Leave a comment:

Re: Vizio E220VA no power
Ok I have checked standby voltages. They were ok. I have a 5v and a 16v rail and both are functioning.
To check the signal to I just attached one lead to ground and the other to the pin, press the button and look for a voltage increase?Last edited by bigstick92; 09-08-2014, 04:23 PM.Leave a comment:

Re: Vizio E220VA no power
Sorry guys I'm kind of new to this. Thanks for all the help so far.
I got some more pictures visible here: [url]http://postimg.org/gallery/ikp8d99a/10e8b524/[/url]
Also I had trouble finding a standby rail (does this model have one?).
Is there an easy way to trace the signal being outputted by the power button?
The T.V. just turned off one day. I had it sitting for a while plugged it in yesterday it turned on then about a half hour later it shut off the display although the light was still on and it became non...Leave a comment:

Vizio E220VA no power
Hi I have a Vizio E220VA that will not power on. No lights appear on even after pushing the power button. I have opened it up and there is no visible component damage and it is getting power. Any ideas?
Thanks. -
