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.

EDITED: I thought my Vizio E470VL has +5VSB and no 12v on the PS board, but after plugging the cable back in and testing the pins on the Main board I realized that I do have 12V. I assume the 12V is turned on when the ON/OFF switch is pressed. The Vizio light in front does go from Standby Orange to White when ON. But, I still have no picture or sound. Test values of PS board are below.
+5VSB= +5.09
12V= +12.18
PS_ON= +2.25
I_ON/OFF= +3.27
LAMP= +3.18
DIM= +2.97
Any more testing I can do on Main board or is it just a replacement?... -

Would someone please help troubleshoot a Vizio 47" TV Switch Mode Power Supply with 5 volt output fluctuating voltage. The voltage fluctuates at 5 the volt output and at the Pulse Switch Modulating IC at VCC. I have the following notes:
1. The 3 main filter caps all have approximately 167 volts steady
2. I have replaced 4 mosfets next to what I think is called the inventor transformer (big black transformer) pictures attached
3. I have replaced Fuse F102 with an equivalent
4. I have check all diodes and caps and they seem to be ok
5. I replaced the 431... -
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...
