Re: vizio E320-A1 not working

C9810 is the main filter cap.

Right when I touch each leg, the meter reads over 100 and then drops rapidly to 0

What should the dial be set to on the volt meter? V w/ wavy line or V with straight line and a dotted line?

Re: vizio E320-A1 not working

VDC = Straight Line
AC = ~ Line
So set to DC.

I got a reading of 410

410VDC? That cannot be true.
Show the picture of your meter reading.

here ya go. I am sure i messed up some setting......

I do want to stop and thank you, for being patient and taking time to help me.

Re: vizio E320-A1 not working

Try checking 9V battery or AA battery or something.
Are you sure the meter is OK?
BTW, when you measure those Voltages on the connector of the power supply that goes to the main board, you did have it set to DCV, right?

a new 9V battery read 9.5

just let me know where to put the red and the black (which 2 pins of that 13 pin connector)

[phan1978]

Re: vizio E320-A1 not working

When I touch pin 11 & 12, I get a reading of over 11V

Re: vizio E320-A1 not working

OK, so in the beginning you had the meter setting to AC that is why you were getting nothing on the connector.
https://www.badcaps.net/forum/attach...3&d=1472951354
So put the black probe on the metal chassis of the TV then use Red probe to measure DCV of each pin except pin 1 (N.C.) and GND pins 7, 8, 9.
Report the reading of each pin like this when TV is plugged in but the power switch is not activated, and when power switch is activated
Power switch is not activated:
Pin 2: 5.2V = XXXV
Pin 3: 5.2V = XXXV
Pin 4:PS_ON = XXXV
...........

Power switch is activated:
Pin 2: 5.2V = XXXV
Pin 3: 5.2V = XXXV
Pin 4:PS_ON = XXXV

Pin 5:+24v= flips anywhere between 12 to 22v quickly

7-9 GND =
10=+12v =flipping anywhere between 3 to 11v quickly
11=+12v =flipping anywhere between 3 to 11v quickly
12= dim =0.20v
13= on/off = 0.40v

NOTE: The TV does nothing when the power button is pressed. Like I said earlier, people with this same issue have reported that the main board was the culprit....I just want to make sure I am diagnosing the correct board

Re: vizio E320-A1 not working

Right now you do not even have steady STANDBY 5.2V to run the main board.
Check the power supply board by itself without any other boards or other cables connected to it except the AC power cord and then check the DCV again.
Something is not making sense that you even has 410VDC on the main cap.

Re: vizio E320-A1 not working

I, too, have a Vizio E320-A1 that will not power on. So, rather than start a new thread, I thought I should continue here. A couple of days ago the light at the bottom left front would light up but the TV would no longer turn on. Now that little light also does not light up. To get the DCVs asked of the owners of problem TVs the only way I can guess the TV is "on" is by unplugging the TV, then plug it in and get the DCVs for "off", then hold the Power button long enough to hope it turned "on" the power and then I took the readings again of the DCVs.

Pin Off On
1
2 5.22 5.22
3 5.22 5.22
4 4.7 4.7
5 24.6 24.6
6 24.6 24.6
7 GND
8 GND
9 GND
10 12.37 12.3
11 12.36 12.3
12 96.3 47
13 57.7 30

From all that I've read I'm thinking my power card is working and the problem lies in my main board. Are there any DVs I can test on the main board to confirm it is the problem?

I have photos of the cards but I've no idea how to upload them.

Re: vizio E320-A1 not working

12 96.3 47
13 57.7 30

Retest pin 12 and 13, no way they can be that high (96V?, 57V?) without TV blowing up. Make sure to read the meter properly, may be mV instead of V?
BTW, ALWAYS put down the pin names when report the readings, see post 53.

Double posted, ignore this post.

Re: vizio E320-A1 not working

please tell me that your measurement for pin 13 is not 30v

can you recheck that when you are powering it on.

Re: vizio E320-A1 not working

you beat me to it bud!

Re: vizio E320-A1 not working

1 NC
2 5.2v
3 5.2v
4 PS_ON
5 +24.6
6 +24.6
7 GND
8 GND
9 GND
10 +12v
11 +12v
12 DIM
13 On/Off

I unplugged the TV, waited, plugged it back in and rechecked the values. No change to any. I used exclusively DCV not touching my multimeter between start and finish. Then I secured the negative probe to ground and put the positive probe on pin 12 then I depressed the on button ON the side of the TV. It continued to read 96.3 and did not change at all while I held down the ON button. Apparently the ON feature is now no longer working. And the TV did not blow up.
