Re: Vizio E320-B0 wont power up
I took more panels off and this is where the ribbon cable goes from the main board. the board it plugs into runs the entire length of the TV and I cannot find any part numbers on it.

Re: Vizio E320-B0 wont power up
ok, since I only see one ribbon cable from the main board, im assuming its other end is connected to the TCON board...which is deeper into the TV. If I disconnect the ribbon cable from the main board, then I should try and power on th TV to see if I get a LED of some sort or should I check voltages somewhere?Leave a comment:

Re: Vizio E320-B0 wont power up
Ok, I have 18.8v on both of those....so I suppose I do have standby voltage. I wasnt sure what the "sb" meant for sure. (never truly worked on TVs and didnt want to assume). So since I have standby voltage, whats to check next?
budm, I appreciate your help and I have been reading information that you have helped others out on their threads too. thank you for your help.Leave a comment:

Re: Vizio E320-B0 wont power up
I have not checked voltage on the Power Supplies. I was able to get that second power supply for $11 shipped so I just went ahead and did that.....possibly for nothing.
I could check for voltage on the board but I cannot find a pinout description of it anywhere. I read some other threads about checking for voltage.
Here is the pinout of the connector going from the power supply to the main board:

Re: Vizio E320-B0 wont power up
if the EEPROM was done, would the power LED not light up at all? wouldnt that mean that no power was getting through the power supply?Leave a comment:

Re: Vizio E320-B0 wont power up
as far as the LED giving a trouble code, nothing. No light of any sort is emitting from the power LEDLeave a comment:

Vizio E320-B0 wont power up
Hey guys,
So I have a Vizio E320-B0 tv and after not using it for awhile I realized that it would not work properly. I plugged it in and it wouldnt turn on, so I just went on with something else and tried to turn it on about 5 minutes later and it came on. It was on for about 45 seconds and then shut off. I then left it as it was overnight and tried the next morning and it worked. I had a few days of it working and then turned it off and then it wouldnt turn back on. When I say that it would not turn on, I mean the little light on the edge of the tv would not even come on, not just the...Last edited by NatureBoy; 07-29-2015, 11:44 AM. -
