Re: vizio E320ao autopsy
I have seen them in Samsung, it is back-lit (deeper chassis) instead of edge-lit (thinner chassis, edge-lit just like monitor). With back-lit, they can do zone dimming better than edge-lit.
I also use them for light box and for taking pictures of the circuit boards.Last edited by budm; 01-05-2014, 08:52 PM.Never stop learning

Re: vizio E320ao autopsy
I had heard of it, but only on premium TV, like LE40A950, called local dimming, not available except on a few exclusive models. Some edge lit TV have 5xVertical and 2xHorizontal dimming, must produce awful halo effect though.
This one probably lights them all up at same brightness regardless.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: vizio E320ao autopsy
I would like to do a hack like "budm" did ,And use the chassis to drive another panel. I couldn't find any info on the net. The chassis supply's 12v to panel and 40 v to the led'sComment

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.

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.... -
Hello everyone, I'm trying to find some service manuals or schematics for a vizio e55u-d2 55 inch tv that just conked out the other night. It has no power whatsoever.
Have tried all the reset process that vizio had.
Any Insight to this would be great and appreciated. If you all think it's not cost prohibited to fix let me know. known thank you and have a wonderful day.
