Re: Vizio E321VL
I'm pretty good for an amateur. I've soldered the e321vl eprom, mini-usb jacks, etc. Any idea where to find one? Google didn't help.Comment

Re: Vizio E321VL
You need to look up the part # on them, but you probably won't be able to buy them unfortunately. You could buy a "converter box" (with composite out) and program the remote to operate the TV.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!
For service manual, schematic, boardview (board view), datasheet, cad - use our search.Comment

Re: Vizio E321VL
any external device w/ a tuner can be a substitute as well, although realize your input may be SD lo-res

Re: Vizio E321VL
Hw00d,
Did you ever get anywhere on this? I just fixed an E470VL with the exact same issue. Main board. I verified the power supply was good by jumping from the 5VSB to PS-ON. I then checked all voltage outputs on the supply as jumped another wire to BL-ON to make sure the backlights worked. At that point I was certain the main was bad. TV running smooth now.Comment

Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.
Upon bringing it home and plugging it up, it showed a standby light.
I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.
The screen seems to blackout and stay black, but with a flashlight I can see the display.
With my Playstation 4 connected via HDMI, and running a game I can hear sound.

Hi.
picked up another TV. This time is a Vizio M65-C1. TV does not turn on. I had repaired another 60 inch vizio , Bad main board.
When power button is pressed, the Power led indicator on the bottom right, turns for a few seconds and then it fades away. No backlight or Vizio logo on screen. Removed back cover and repeated test.
This is the TV This TV is a little different from the Samsung I have worked on. Power supply is on the Left side, Main Bd is on the right side, T-CON , not in the picture is on the bottom. I am assuming that the boards in the middle are the LED... -
Failure Symptom
No picture, just red vertical stripes. Google search shows quite common problem for these recent Vizio M series although red vertical stripe pattern may differ. Some call it "Netflix" boot screen haha.
Where is the short?
Panel has 4x buffer boards. Quickly found the 1/4 panel buffer board with the problem by selectively disconnecting buffer board flex cables.
Having recently fixed another Vizio with similar symptoms that was a shorted ESD diode array ( link ) Probed the ESD diode array but... -
Bug looks like hardware so thought I posted it here. Exact same behavior on 2 different model 4K Vizio TVs running their SmartCast smarttv software. After launching youtube app, press vizio button on remote to return to the smarttv menu, once in awhile, a column of bad pixels will show for few seconds on the left hand side.
It seems the vizio software is reinitializing hardware when returning to the smarttv menu. In general, SmartCast software isn't very good. Also will randomly (relatively infrequent) get no network connection when on wifi and require reboot....
