Re: Vizio E320_B0E logo flashes then goes dark.
I tested the MOSFET N gate with data sheet providing pins.
This is odd though.
Source Voltage: 0.3mV
Drain Voltage: 1.60v
Gate Voltage: .8mV

OK, VOut1 gives me 18.9v and stays there. It jumps up to maybe 70 then levels back to 18.9. Led1 however peaks to 1.3v and rolls off to .2v and that's really about it. Attached and unattached wire reads the same. I noticed that led1 goes into a SOT-223 MOSFET? Not sure how I would test that.Leave a comment:

Alright, I tested the led connector. Both with it plugged in and unplugged. The TV still powers on without that cable connected. I can't get a reading on this output. Around the same time the back lighting flashes, I see a jump in voltage than it goes back to nothing. (Nothing means random numbers going rampant on the display.)
It does seem to be something on the power board then, if I could externally power the back light I could have a working tv. Not saying I would even attempt that. Just a thought

The LED strips I believe is powered off of the three wires on the powerboard towards the top. Correct?
I see LED1,NC,VOUT.Last edited by terryallen44; 10-11-2016, 05:16 PM.Leave a comment:

Thank you for replying. I tested the Backlight pin and received a constant 3.3V.Leave a comment:

Vizio E320_B0E logo flashes then goes dark.
Hello all, I got this TV from a friend that was throwing it out but I took it instead.
He advises that it would flash and then the screen would turn off however there was still sound. I was able to duplicate the issue easily.
I do believe it is something with the backlighting or the eeprom. You can turn the TV on under a bright light and see things on the set moving as well as the menus.
I'm not too sure where to go from here. Caps looked good.

Hey world. As you can see my name is Terry Allen and I mainly joined this forum in an attempt to get some help getting a TV back going that was given to me.Leave a comment:
